[PATCH v2 0/7] uapi: export all headers under uapi directories

[PATCH v2 0/7] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Here is the v2 of this series. The first 5 patches are just cleanup: some
exported headers were still under a non-uapi directory.
The patch 6 was spotted by code review: there is no in-tree user of this
functionality.
The last patch remove the use of header-y. Now all files under an uapi
directory are exported.

asm is a bit special, most of architectures export asm/<arch>/include/uapi/asm
only, but there is two exceptions:
 - cris which exports arch/cris/include/uapi/arch-v[10|32];
 - tile which exports arch/tile/include/uapi/arch.
Because I don't know if the output of 'make headers_install_all' can be changed,
I introduce subdir-y in Kbuild file. The headers_install_all target copies all
asm/<arch>/include/uapi/asm to usr/include/asm-<arch> but
arch/cris/include/uapi/arch-v[10|32] and arch/tile/include/uapi/arch are not
prefixed (they are put asis in usr/include/). If it's acceptable to modify the
output of 'make headers_install_all' to export asm headers in
usr/include/asm-<arch>/asm, then I could remove this new subdir-y and exports
everything under arch/<arch>/include/uapi/.

Note also that exported files for asm are a mix of files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/x86/include/uapi/asm/Kbuild;
 - arch/x86/include/asm/Kbuild.
This complicates a lot the processing (arch/x86/include/asm/Kbuild is also
used by scripts/Makefile.asm-generic).

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. I don't know if it should be
made against antoher tree.

Comments are welcomed,
Nicolas

[PATCH v2 5/7] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that unput-files3-name is genhdr-y.

[PATCH v2 7/7] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-unicore32/shmparam.h
asm-unicore32/ucontext.h
asm-hexagon/shmparam.h
asm-mips/ucontext.h

+All headers under include/uapi/, include/generated/uapi/,

-	header-y specifies header files to be exported.
+	subdir-y may be used to specify a subdirectory to be exported.
 
 		Example:

+			#arch/cris/include/uapi/asm/Kbuild

-	genhdr-y specifies generated files to be exported.
-	Generated files are special as they need to be looked

It should rather not be exported - please remove it from
arch/x86/include/uapi/asm/Kbuild instead.

Thanks.

Just hint for the future:
-M (move)
-C (copy)
-D (delete) [though this is NOT for applying]

Moving the file is correct as far as I can tell, but the extra
#include is not necessary here, as the kernel will automatically
search both arch/arm/include/ and arch/arm/include/uapi/.

The same applies to patches 2 and 4.

This one is only a redirect to an asm-generic header, so it can be
removed completely and replaced with a line in the 
arch/nios2/include/uapi/asm/ file:

generic-y += setup.h

Since this is meant as a cleanup, I commented on this to point out a cleaner
way to do the same.

This is interesting, though not your problem. Maybe someone who understands
cris better can comment on this: How is the decision made about which of
the arch/user.h headers gets used? I couldn't find that in the sources,
but it appears to be based on kernel compile-time settings, which is
wrong for user space header files that should be independent of the kernel
config.

I don't know if anyone still uses "make headers_install_all", I suspect
distros these days all use "make headers_install", so it probably
doesn't matter much.

In case of cris, it should be easy enough to move all the contents of the
uapi/arch-*/*.h headers into the respective uapi/asm/*.h headers, they
only seem to be referenced from there.

For tile, I suspect that would not work as the arch/*.h headers are
apparently defined as interfaces for both user space and kernel.

The series should probably get merged through the kbuild tree, but testing
it on mainline is fine here.

Indeed, I'd like to see the include/asm file gone.

I'm pretty sure these should not be exported!

I believe it's since the CRISv10 and CRISv32 are very different beasts,
and that is selected via kernel config...

This part of the CRIS port has been transformed a couple of times from
the original layout without uapi, and there's still some legacy silliness,
where some files might have been exported but never used from userspace
except for some corner cases.

Those files are created in every directory:
$ find usr/include/ -name '\.\.install.cmd' | wc -l
71
$ find usr/include/ -name '\.install' | wc -l
71

That still does not mean they should be exported.

Anything but headers (and directories as a skeleton structure) is maximally suspicious.

What I was trying to say is that I export those directories like other are.
Removing those files is not related to that series.

Perhaps the correct solution is to only copy files matching "*.h" to
reduce the risk of copying files incidentally created by kbuild but
which shouldn't be installed as uapi headers.

[PATCH v3 0/8] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Here is the v3 of this series. The first 5 patches are just cleanup: some
exported headers were still under a non-uapi directory or (x86 case) were
wrongly exported.
The patch 6 was spotted by code review: there is no in-tree user of this
functionality.
Patches 7 and 8 remove the need to list explicitly headers. Now all files
under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. If I must rebase it against the kbuild
tree, just tell me ;-)

v2 -> v3:
 - patch #1: remove arch/arm/include/asm/types.h
 - patch #2: remove arch/h8300/include/asm/bitsperlong.h
 - patch #3: remove arch/nios2/include/uapi/asm/setup.h
 - patch #4: don't export msr-index.h
 - patch #5: fix a typo: s/unput-files3-name/input-files3-name
 - patch #6: no change
 - patch #7: fix include/uapi/asm-generic/Kbuild.asm by introducing mandatory-y
 - add patch #8

v1 -> v2:
 - add patch #1 to #6
 - patch #7: remove use of header-y

Comments are welcomed,
Nicolas

[PATCH v3 5/8] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

[PATCH v3 7/8] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-unicore32/shmparam.h
asm-unicore32/ucontext.h
asm-hexagon/shmparam.h

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/<arch>/include/uapi/asm/Kbuild;
 - arch/<arch>/include/asm/Kbuild.

[PATCH v3 8/8] uapi: export all arch specifics directories

[Nicolas Dichtel]

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
 - arch-v[10|32] for cris;
 - arch for tile.

These weren't defined by the kernel before, so why do we need to define them
now?

Will defining __UINTPTR_TYPE__ cause problems in compiling libboost by
changing the signature on C++ functions that use uintptr_t?

I see it on my desktop as /usr/include/asm/msr-index.h and it's been there at
least four years - and as such it's part of the UAPI.  I don't think you can
remove it unless you can guarantee there are no userspace users.

It is listed in include/uapi/asm-generic/Kbuild.asm, which is included by
arch/arm/include/uapi/asm/Kbuild.

You can also have a look at patch #5 to see why it was exported even if it was
not in an uapi directory.

I keep it in the v2 of the series, but the maintainer, Borislav Petkov, asks me
to un-export it.

I will follow the maintainer decision.

I mentioned it to David, and he says it's because the long list of
recipients is breaking his mailer.  I've already posed the question
about whether that's exploitable!

We really should not be installing non-uapi header files to userland
under _any_ circumstance - this to me sounds like a bug in kbuild.

The assumption is that headers outside of uapi directories are not
part of the user visible API, and so can be freely modified - which
in the presence of this bug is untrue.

However, as it's happening, and this header has been there since 2013
(commit 09096f6a0ee2 - "ARM: 7822/1: add workaround for ambiguous C99
stdint.h types") it's now well and truely part of the user API whether
we intended it to be or not, so your patch looks to me like the correct
thing to do.

I think it needs further evaluation to make sure kbuild isn't going to
do something else silly, like subsitute include/asm-generic/types.h for
the now missing arch/arm/include/asm/types.h

I wonder how many more headers are unintentionally exported.

... what a mess. :(

I'm not the maintainer. I simply think that exporting that file was
wrong because it if we change something in it, we will break userspace.
And that should not happen - if userspace needs MSRs, it should do its
own defines.

I'm taking this patch, but with the following commit log:

  Due to the way kbuild works, this header was unintentionally exported
  back in 2013 when it was created, despite it not being in a uapi/
  directory.  This is very non-intuitive behaviour by Kbuild.

  However, we've had this include exported to userland for almost four
  years, and searching google for "ARM types.h __UINTPTR_TYPE__" gives
  no hint that anyone has complained about it.  So, let's make it
  officially exported in this state.

If anyone has any objections, they better shout sooner rather than
later.

[Razvan Cojocaru]

This series aims to prevent the display from freezing when
enabling altp2m and switching to a new view (and assorted problems
when resizing the display).

The first patch introduces p2m_{init,free}_logdirty(), the second
allocates  a new logdirty rangeset for each new altp2m, and the
fourth propagates (under lock) changes to all p2ms.

Since the last version of the series, what has previously been
the first patch is already upstream, and two patches kindly
authored by George Dunlap have been appended. The patches
optimize the way rangeset changes are propagated in
change_type_range().

[PATCH V7 1/5] x86/mm: introduce p2m_{init,free}_logdirty()
[PATCH V7 2/5] x86/mm: allocate logdirty_ranges for altp2ms
[PATCH V7 3/5] x86/altp2m: fix display frozen when switching to a new view early

Subject: [PATCH v9] VT-d: use correct BDF for VF to search VT-d unit

When SR-IOV is enabled, 'Virtual Functions' of a 'Physical Function' are under
the scope of the same VT-d unit as the 'Physical Function'. A 'Physical
Function' can be a 'Traditional Function' or an ARI 'Extended Function'.
And furthermore, 'Extended Functions' on an endpoint are under the scope of
the same VT-d unit as the 'Traditional Functions' on the endpoint. To search
VT-d unit, the BDF of PF or the BDF of a traditional function may be used. And
it depends on whether the PF is an extended function or not.

Current code uses PCI_SLOT() to recognize an ARI 'Extended Funcion'. But it
is conceptually wrong w/o checking whether PF is an extended function and
would lead to match VFs of a RC endpoint to a wrong VT-d unit.

This patch uses VF's 'is_extfn' field to indicate whether the PF of this VF is
an extended function. The field helps to use correct BDF to search VT-d unit.

Reported-by: Crawford, Eric R <Eric.R.Crawford@intel.com>
Signed-off-by: Chao Gao <chao.gao@intel.com>
---
v9:
 - check 'is_virtfn' first in pci_add_device() to avoid potential error if
 linux side sets VF's 'is_extfn'
 - comments changes to make it clear that we use VF's 'is_extfn' intentionally
 otherwise the patch seems like a workaround.

v8:
 - use "conceptually wrong", instead of "a corner case" in commit message
 - check 'is_virtfn' first in acpi_find_matched_drhd_unit()

v7:
 - Drop Eric's tested-by
 - Change commit message to be clearer
 - Re-use VF's is_extfn field
 - access PF's is_extfn field in locked area

Hi, thanks for the reply.

Literally 10 minutes after sending this, I thought that a bzero would

Hi guys,

Do you know when *recognized* Virtual Interrupt on VM-Entry will be
delivered if Virtual-Interrupt Delivery is enabled and interrupt delivery
is blocking by STI?

Previously, VMM used Interrupt-Window, but as I see in XEN code,
Interrupt-Window is not used when Virtual Interrupt Delivery is enabled.

Does it mean, we will get Virtual Interrupt on the next VM-entry?

Thank you!

This means you have not installed the libvirt, libxl driver. Or that
you have, but trying to load it is failing.

There should be something in the libvirt logs.

However, since you said you've installed Xen from sources, you probably
need to build and install libvirt from sources too.

In fact, I don't know how exactly it is in Ubuntu, but in all the
distro I've tried, trying to install libvirt-daemon-driver-libxl (or
whatever the package is called), would fail, unless Xen hypervisor,
toolstack and libraries are also installed with the distro package
mamanger.

If that is not the case, install would either fail, or would bring in
those Xen packages, which would then either overrun or conflict with
your source installation.

As said above. In all the distro I tried, when I build Xen from source,
I've always also had to build libvirt from sources.

Hello,

I have installed Ubuntu 15.10 in which have installed Xen with source.

Booting is done with Xen as well as commands like xl infor, xl list are
also working fine.

For creating Virtual Machine, I have installed Virtual Machine Manager, but
when I try to run it, it gives error as follows:







*Unable to connect to libvirt.internal error: libxenlight state driver is
not activeVerify that: - A Xen host kernel was booted - The Xen service has
been started*

I tried by installing libvirt as
apt-get install libvirt-bin

but, still the same problem is found. Libvirtd service is also not getting
started.

Where am I lacking?

Thank you,

Thankyou for the fixes; they are both good.

For future fixes, please can you CC the appropriate maintainers
(https://wiki.xen.org/wiki/Submitting_Xen_Project_Patches#Cc_the_maintainer_of_the_code_you_are_modifying),
and you probably want to join the xen-devel mailing list to avoid

You need to add your Signed-off-by to all patches you touched for

This kind of situation is not that uncommon.  For any part of our
system where we don't offer a stable API, or at least one-way
intercompatibility, it is necessary to make incompatible changes both
in the producer and in all consumers.

(Sometimes this can mean a patch to xen.git needs to be combined with
a QEMU_TAG update for qemu-trad, too; in theory trying to decouple the
Xen API for qemu upstream.)

Ian.

   Recently , I made a test to compare the performance of I/O between xen project and xenserver. I found the performance of xenserver is much better than that of xen project .

I want to find the reason why xenserver is better so I search through google.com. On the website www.xenproject.org<http://www.xenproject.org> , I found url http://wiki.xenproject.org/wiki/Tuning_Xen_for_Performance and http://wiki.xenproject.org/wiki/Network_Throughput_and_Performance_Guide .
I set these parameters as the url given. But , it looks doesn’t work. The performance got no obvious improvement.

So , I send this mail to get some advise . will you help me ? if so , I’ll  be much appreciate.

I think it often does make sense to check things out by component.  And
of course before xenalyze was in tree, it doesn't matter when the change
was done.  I suppose I've always been prejudiced against
xentrace_format, which is why I'd never thought about regressions in it
(although I probably should have).

But now that xenalyze is in-tree, I think we want to avoid situations
where the in-tree xenalyze is broken, even just for one changeset, if we
can avoid it.

Thanks,
 -George

So, you're saying I should change both Xen, xentrace_format and
xenalyze.c all at once, in the same patch, right?

I'm asking just to double check, as, although I see your point,
separating things by component seemed a good thing to do to me, even at
the price you describe, and I've done it before. :-)

As said, I'm fine doing that, I just want to be sure this is what you
are asking.

The change looks good in itself; but it makes me realize that
technically by changing the trace format, the previous patch
introduced a regression which is fixed here.  There's a part of me
that's tempted to overlook it because it's minor, but on balance I
think we should try to be diligent with this sort of thing.

Could you re-send this with the trace change moved from the previous
patch to this patch?

If you don't make any other changes, you can retain the reviewed-by of
the previous patch, and add this one to this patch:

Subject: Bump library names just after branching
Reply-To: 

Hello,

Currently we bump the shared library names just before the release, so ATM 
xen-unstable is still using the library names from the 4.6 release. This is 
an issue if someone wants to install both Xen 4.6 and xen-unstable in the 
same box (unless you use a different prefix/DESTDIR), because libraries from 
xen-unstable will replace the stable ones.

IMHO, it would make more sense to bump the library names just *after* we 
branch and open the tree for development again. We could even have the 
library name versions be set based on XEN_VERSION and XEN_SUBVERSION, so 
that we don't need to go around the different library makefiles bumping the 
versions manually.

Roger.

Hello,
As asked of in the previous mail, I tried compiling Xen from source.
I am not sure whether we can ask questions for the task given, but I have
been stuck at it from yesterday.
I followed all the steps, and wherever there was some problem, I looked up
that in wiki of Xen, but after building and installing that with ovmf
enabled in ./configure, I moved on to the network configuration, and on
rebooting after the configuration, it is showing ' ERROR: Can't find
hypervisor information in sysfs!' on xm list and brctl shows no bridge
enabled. On further checking, it showed 'ERROR: Not running inside Xen'.
I have tried finding the problem, and I will check this again but I can't
move forward until the hypervisor runs!
Not sure where to check for the error.

Thank you,

Ayushi.

I'm intending to be able to do database schema updates.  But I don't
want to play around with such code on a live database.  So I need a
test database.

Thus, a yak: arrangements to make a test database.

As I say, I have tested this and it now does the right things in,
apparently, the right order, and seems to leave things in a good state
even when it collapses halfway or is ^C'd.

In v2 I have addressed the comments, and added a couple of new safety
catches.  For ease of review these are mostly as followup patches to
the mg-schema-test-database script, rather than folded in.

Your Core i3 is a Dual Core Processor with Hyper Threading. Hyper Threading allows each Core to run two Threads simultaneously, in what is called physical Core and virtual Core (Or around those lines, but you get the idea). They share resources, and the extra Thread actually gets the free resources/execution time that weren't used by the main Thread. As Core 3 is the virtual core of the physical Core 2 (Assuming that on Linux it sees and numbers them as Physical Core 0, Logical Core 1, Physical Core 2 and Logical Core 3 and so on), you're giving that VM just a spare virtual Core with the free resources that weren't used by the physical Core. You should try with a full physical Core (Core 2 and 3), otherwise whatever runs on Core 2 WILL impact heavily what you see on Core 3.

I think most i3's have Intel's hyper-threading. If this is a 2 core/4 
thread chip, I would expect this kind of result. I also know that for 
the "sandy bridge" version I am using:

Intel® Xeon® E3-1260L processors (“Sandy Bridge” microarchitecture)
(2.4/2.5/3.3 GHz, 4 cores/8 threads)

How many instruction per second a thread gets does depend on the 
"idleness" of other threads (no longer just the hyperThread's parther). 
For example running my test code that does:


0x0000000000400ee0 <workerMain+432>: inc %eax
0x0000000000400ee2 <workerMain+434>: cmp $0xffffffffffffffff,%eax
0x0000000000400ee5 <workerMain+437>: jne 0x400ee0 <workerMain+432>

for almost 4GiI in this loop.

On the setup:

Curious.  Lets try ruling some things out.

How are you measuring time in pv499?

What is your Cstates and Pstates looking like?  If you can, try
disabling turbo?

Hi all,

I  am  now successfully running my little operating system inside Xen.
It  is  fully  preemptive and working a treat, but I have just noticed
something  I  wasn't expecting, and will really be a problem for me if
I can't work around it.

My configuration is as follows:

1.- Hardware: Intel i3, 4GB RAM, 64GB SSD.

2.- Xen: 4.4 (just pulled from repository)

3.- Dom0: Debian Wheezy (Kernel 3.2)

4.- 2 cpu pools:

# xl cpupool-list
Name               CPUs   Sched     Active   Domain count
Pool-0               3    credit       y          2
pv499                1  arinc653       y          1

5.- 2 domU:

# xl list
Name                                        ID   Mem VCPUs      State   Time(s)

pv499                                        3   128     1     -b----      61.2

6.- All VCPUs are pinned:

# xl vcpu-list

7.- pv499 is the domU that I am testing. It has no disk or vif devices
(yet). I am running a little test program in pv499 and the timing I
see is varies depending on disk activity.

My test program runs prints up the time taken in milliseconds for a
million cycles. With no disk activity I see 940 ms, with disk activity
I see 1200 ms.

I can't understand this as disk activity should be running on cores 0,
1  and 2, but never on core 3. The only thing running on core 3 should
by my paravirtual machine and the hypervisor stub.

Any idea what's going on?

This had been posted way way back:  https://lkml.org/lkml/2013/1/16/696

and the discussion about it was:
 - If there are no uses of v2, then why not rip out the support for it.
   [b/c the work for it would be in the networking code and I am still
    hoping that will be done?]
 - Why not do all of this in the toolstack. Enforce that the guest
   can only use v1 ".. if the backend isn't going to make use of them."
   (Matt).
   I am not sure how one would set up the plumbing to properly figure out
   whether the backend (say a driver domain) would communicate to hypervisor
   or XenBus that it is going to use v1 only if it has not yet started.
   (It would not have started b/c the guest hasn't started yet).

   My thinking is that once the frontend and backend start using the
   esoteric features of v2 we can rip this patch out. And also implement
   the proper code for PVHVM/PVH to actually use v2 grants.

These document pretty important aspects of behavior (fixing what might 
be considered documentation bugs), and obviously can have no functional 
impact.  I guess the only risk is that they might be wrong and mislead 
someone, but I think that's pretty low. :-)

This series removes the usleeps and waiting loops in libxl_dom.c and
replaces them with event-callback code.

Firstly, some documentation of things I had to reverse-engineer:
 01/23 xen: Document XEN_DOMCTL_subscribe
 02/23 xen: Document that EVTCHNOP_bind_interdomain signals
 03/23 docs: Document event-channel-based suspend protocol
 04/23 libxc: Document xenctrl.h event channel calls
Arguably these might be 4.4 material (hence the CC to George).

We want some additional libxl event facilities:
 05/23 libxl: init: Provide a gc later in libxl_ctx_alloc
 06/23 libxl: init: libxl__poller_init and _get take gc
 07/23 libxl: events: const-correct *_inuse, *_isregistered
 08/23 libxl: events: Provide libxl__xswait_*
 09/23 libxl: events: Use libxl__xswait_* in spawn code
 10/23 libxl: events: Provide libxl__ev_evtchn*

We need to clean up some unfortunate code in libxc:
 11/23 libxc: suspend: Rename, improve xc_suspend_evtchn_init
 12/23 libxc: suspend: Fix suspend event channel locking

We do some shuffling around of the libxl suspend control flow:
 13/23 libxl: suspend: Async libxl__domain_suspend_callback
 14/23 libxl: suspend: Async domain_suspend_callback_common
 15/23 libxl: suspend: Reorg domain_suspend_callback_common
 16/23 libxl: suspend: New libxl__domain_pvcontrol_xspath
 17/23 libxl: suspend: New domain_suspend_pvcontrol_acked
No functional change in those five.  These changes are broken down
just to make the changes reviewable.

Finally, we can start to work on the event code, removing the bugs,
usleeps and loops one at a time:
 18/23 libxl: suspend: domain_suspend_callback_common xs errs
 19/23 libxl: suspend: Async xenstore pvcontrol wait
 20/23 libxl: suspend: Abolish usleeps in domain suspend wait
 21/23 libxl: suspend: Fix suspend wait corner cases
 22/23 libxl: suspend: Async evtchn wait
 23/23 libxl: suspend: Apply guest timeout in evtchn case

I have tested this with a Debian pvops kernel (xenstore pvcontrol
suspend signalling) and OpenSUSE 11 (event channel suspend
signalling).

Shriram: I haven't really touched the Remus-specific code here but
this series ought to be suitable for you to base things on, assuming
my co-maintainers like the general approach.

Thanks,
Ian.

According to http://wiki.xen.org/wiki/Xen_Version_Compatibility :

"Xen supports migration (including live migration and save restore)
both within a stable release branch (e.g. between any versions in the
4.2.x branch) and from one major release to the next (e.g. from
release N to releaseN+1). This allows one to upgrade a pool of Xen
hosts by evacuating and upgrading the hosts one by one.

"Although it is not formally supported skipping a major release (e.g.
migration from release N to release N+2) may often work. "

Unfortunately that would mean 3.1 -> 3.2 -> 3.3 -> 3.4 -> 4.0 -> 4.1
-> 4.2... at that point shutting down the VM and starting it back up
again looks like the more attractive option.

This is an RFC of Linux guest-side implementation of the FIFO-based
event channel ABI described in this design document:

http://xenbits.xen.org/people/dvrabel/event-channels-E.pdf

Refer also to the Xen series.

Remaining work:

* Add an function to set a event channel's priority and use this to
  set the VIRQ timer to the highest priority.

Patch 1 is a obvious refactoring of common code.

Patch 2-6 prepare for supporting multiple ABIs.

Patch 7 adds the low-level evtchn_ops hooks.

Patch 8-9 add an additional hook for ABI-specific per-port setup
(used for expanding the event array as more event are bound).

Patch 10 allows many more event channels to be supported by altering
how the event channel to irq map is allocated.  Note that other
factors limit the number of supported IRQs (IRQs is 8192 + 64 *
NR_CPUS).

Patch 11 is some trival refactoring.

Patch 12-13 add the ABI and the implementation.

Hi,

In my case I used the live migration for VoIP service. I make a simple
measurement by using wireshark,  I generate the call and then shut down one
of my virtual machine. Then using packet captured via wireshark I generate
the jitter using telephony RTP stream anaysis. If you read the report you
may see the maximum delta that correlated to the downtime in my case for my
voip service.

Is it possible for Xen to resync its wallclock time from the RTC device
whenever it gets a request of starting a new guest? as usually a new
guest OS needs to get the time base from Xen's wallclock anyway.

Yep.  The shadow code uses the same p2m implementataion as NPT, so that
should all be fine.

Yep.  You'll already be doing a p2m lookup to get the MFN, so you just
need to look at the p2ma as well.

Yes.  The common case will be handled in _sh_propagate, which is where
the shadow PTE is constructed.  For the rest you'll need to look at the
places where the shadow fault handler calls the emulator and DTRT
(either before the call or in the callbacks that the emulator uses to
access guest memory).

That's right.  It's also used to track which parts of an emulated
framebuffer have been updated, to make VNC connections more efficient.

There's one set of shadows per domain, shared among all VCPUs.  A given
page of memory may have multiple shadows though, e.g. if it's seen both
as a top-level pagetables and a leaf pagetable. 

Shadows are kept around until:
 - it looks like the page is no longer a pagetable;
 - the guest explicitly tells us it's no longer a pagetable; or
 - we need the memory to shadow some other page. 

Mostly, a pages's shadow(s) are kept in sync with any changes the guest
makes to the page, by trapping and emulating all writes.  For
performance, we allow some l1 pagetables to be 'out of sync' ('oos' in
the code), letting the guest write to the page directly.  On guest CR3
writes (and other TLB-flush-related activity) we make sure any OOS
shadows are brought up to date.

It depends how often you're changing the access permissions.
sh_remove_all_mappings() and sh_remove_write_access() will try to flush
mappings of a single MFN from the shadows, but they can be expensive
(e.g. involving a brute-force scan of all shadows) so if you're going to
do a lot of them it may be worth considering batching them up and
calling shadow_blow_tables() once instead.

Cheers,

Tim.

[-- Attachment #1.1: Type: text/plain, Size: 3206 bytes --]

Hi,

I'm finally to a point where I can start looking at this more closely. I'm
trying to wrap my head around the shadow code to figure out the right
course of action.

I'd want HVMOP_set_mem_access to work with both shadow and EPT, so I'd want
things to work via p2m somehow. I think I understand this part.

* HVMOP_set_mem_access is used to change the p2m_access_t for the target
page(s). This should already be implemented I think?
* During propagation, I'll check the p2m map to see if I should mask off
any permission bits.
* On a shadow paging fault, I'll check if the fault was caused by p2m
permissions, somehow integrating that with the code for read-only guest
page tables safely.

Questions:

* Just for background, am I correct in my understanding that the log_dirty
code is used to track which gfns have been written to by the guest, in
order to speed up migration?
* Are multiple shadow tables maintained per domain? Is there one per VCPU?
One shadow table per guest page table? Is it blown away every time the
guest changes CR3? I'm having some trouble tracking this down.
* How should I clear/update existing shadow entries after changing the
p2m_access_t? Can I clear the shadow tables somehow and force everything to
be repopulated? Is that insane?

Thanks!

Greetings All,

I am very new to Xen but have spent a considerable amount of time
researching various emulators and simulators like QEMU, Virtualbox, Bochs,
etc.... to find out which may be good for a project that I am interested in
moving towards related to the x86_64 platform.

It seems that XEN may be the best solution as I need something that can be
billed as a Type I and also Type II emulator. Xen and HXen meet these goals.

Now I am entering the learning curve to get a feel for the source code but
had a question related to the layout of Xen.

I am trying to understand where the main init functions are in Xen as for
example in QEMU they are in the v1.c file and as to where the mian loops
are for the hypervisor are to loop through the vCPU's.

I am also trying to get a feel for where the memory allocation functions
are in Xen.

Also, in the Xen 4.2.1 distro, is qemu called for each HPV.

Please forgive these questions if they should be obvious to me, but I would
like to get a good feel for the booting sequence and control loops that Xen
has to utilize.

I have read a number of documents on the website that give me briev
overview of how Xen operates with  Dom0 and DomU guests but now it is time
for me to get a feel for the sources so that I might be able to learn and
contribute to the effort of a very wonderful hypervisor.

Any guidance or help would be greatly appreciated.

Kind Regards and have a great day,
Lonnie T. Cumberland

Does xcp supports assignment of USB or xen-api ? I know that spice allows
for USB redirection. Also remote desktop supports redirection of devices. I
like using android devices with xen hosted servers as remote desktop
exports my SD cards to server.

Digvijay,

You have cross posted this message to multiple lists I have already
asked you not to do this on at least one occasion.

You have also CCd various people, including myself, seemingly at random,
*and* posted the same message three times in quick succession.

Please stop this antisocial behaviour.

Post to a single list (xen-users@ in the common case for the sorts of
questions you are asking) and wait a reasonable amount of time (i.e.
measured in days) for a response before pinging.

Ian.

It might be useful to get mem-event working with shadow by following
Tim's suggestions to achieve what you are after.

Yes, the mem-event api, and in particular the HVMOP_set_mem_access
hypercall, looks like what you want.  As you say, there isn't much
documentation for it, except the xen-access.c client and the mailing
list archive.

It works by EPT.  The guest can't detect it by looking at its pagetables
or page fault patterns, though it might be able to detect it by looking
at timings.

Your best bet is to modify _sh_propagate.  Look at how it handles
shadow_mode_log_dirty() -- any time a writeable mapping is shadowed, the
shadow PTE is made read-only until the guest is actually doing a write,
then mark_dirty can be called.  You should be able to do the same thing
for other kinds of access.

Cheers,

Tim.

You'll find it in the xen-unstable tree.  In general the memory-sharing
code in 4.1.x is not stable enough to use.

Hi all,

These 2 patches try to fix the "perf top" soft lockups under Xen
reported by Steven at: https://lkml.org/lkml/2012/2/9/506

I tested it with 3.4-rc2 and "perf top" works well now.

Steven,
Could you please help to test it too?

The soft lockup code path is:

__irq_work_queue
  arch_irq_work_raise
    apic->send_IPI_self(IRQ_WORK_VECTOR);
      apic_send_IPI_self
        __default_send_IPI_shortcut
          __xapic_wait_icr_idle

static inline void __xapic_wait_icr_idle(void)
{
        while (native_apic_mem_read(APIC_ICR) & APIC_ICR_BUSY)
                cpu_relax();
}

The lockup happens at above while looop.
                                                                
The cause is that Xen has not implemented the APIC IPI interface yet.
Xen has IPI interface: xen_send_IPI_one, but it's only used in
xen_smp_send_reschedule, xen_smp_send_call_function_ipi and
xen_smp_send_call_function_single_ipi, etc.

So we need to implement Xen's APIC IPI interface as Ben's patch does.
And implement Xen's IRQ_WORK_VECTOR handler.

Ben Guthro (1):
      xen: implement apic ipi interface

      xen: implement IRQ_WORK_VECTOR handler

Then I think your Dom0 (i.e. kernel 3.x.x) has some problems with
xsave/xrstor.

I didn't change the kernel, it's a fresh install.
I tried the latest for Fedora 16 and Xubuntu 11.10 both 
rebooted the machine.

Xen-unstable supports xsave/xrstor. You are using kernel 3.x.x, which
should support xsave/xrstor too. You can try to set xsave=0 in xen.gz
line of grub entry and boot again. Something like this:

kernel /boot/xen.gz blah blah xsave=0
module blah blah
blah

Oh, i see, it's some new functionality. I will try it tomorrow and then let you know how it goes.

Thank you for the help.

The xsave=0 command line parameter solves the problem.

Thank you,

[Wei Huang]

Then I think your Dom0 (i.e. kernel 3.x.x) has some problems with 
xsave/xrstor.

Xen-unstable supports xsave/xrstor. You are using kernel 3.x.x, which
should support xsave/xrstor too. You can try to set xsave=0 in xen.gz
line of grub entry and boot again. Something like this:

kernel /boot/xen.gz blah blah xsave=0
module blah blah
blah

Oh, i see, it's some new functionality. I will try it tomorrow and then let you know how it goes.

Sorry about the untitled message. 

Should I be the one disabling xsave or is that for Andrew to change something?
How can I do that?

Anyway, shouldn't Xen support it?

What is your Linux command line? does it include "console=hvc0"? 
Perhaps some early_printk settings are required.

Please include my email in your replies, thank you.

Yes, it includes hvc0. I used your tutorial to setup the SOL.

title        Xen 3.4.2 / pv_ops Linux dom0 2.6.31.6 with a serial console

Something like this, I am not at the machine anymore.

Once again, I have not executed the code in this series!

These three are intended to be bugfixes to sort out
the deadlock problem that Roger Pau Monne reported:
 01/15 libxl: ao: allow immediate completion
 02/15 libxl: fix hang due to libxl__initiate_device_remove

These are other bugfixes:
 03/15 libxl: Fix eventloop_iteration over-locking
 04/15 libxl: Fix leak of ctx->lock
 05/15 libxl: abolish libxl_ctx_postfork
 06/15 tools: Correct PTHREAD options in config/StdGNU.mk
 07/15 libxl: Use PTHREAD_CFLAGS, LDFLAGS, LIBS
 08/15 libxl: Crash (more sensibly) on malloc failure

These are handy new bits for internal libxl users:
 09/15 libxl: Make libxl__zalloc et al tolerate a NULL gc
 10/15 libxl: Introduce some convenience macros
 11/15 libxl: Protect fds with CLOEXEC even with forking threads
 12/15 libxl: libxl_event.c:beforepoll_internal, REQUIRE_FDS
 14/15 libxl: Provide libxl_string_list_length
 15/15 libxl: Introduce libxl__sendmsg_fds and libxl__recvmsg_fds

This is the new child-handling machinery:
 13/15 libxl: event API: new facilities for waiting for subprocesses

There are not any users for much of this code in this series.  I have
a half-written rework of libxl_bootloader.c to make it event-driven,
but it's not suitable for review at this stage.  It doesn't even
compile.

Subject: [RFC PATCH 0/6] libxl: New child process handling
In-Reply-To: 

This is the first draft of my new libxl API for child process
handling.

 1/6 libxl: Fix leak of ctx->lock
 2/6 libxl: abolish libxl_ctx_postfork
 3/6 tools: Correct PTHREAD options in config/StdGNU.mk
 4/6 libxl: Protect fds with CLOEXEC even with forking threads
 5/6 libxl: libxl_event.c:beforepoll_internal, REQUIRE_FDS
 6/6 libxl: event API: new facilities for waiting for subprocesses

Please comment.  I'm particularly keen on comments about:

 * The correctness of the pthread_atfork logic in 4/6.
 * The sufficiency for applications of the child handling API in 6/6.
 * The portability of the pthread command line option changes in 3/6.
 * Correctness :-).

If you want to apply it to make sense of, you'll need to know that
this series is on top of my recently-posted 3-patch libxl event fixup
series.

Thanks,
Ian.

This is a 2.6.18-xen patch. I'm not especially interested in that tree
-- Jan looks after it though and picked up this patch from the resend.

netback: disable features not supported by netfront

Netback works by first setting all possible features, and then
resetting some after connection, if the front-end didn't negotiate them.
Except that in the old 2.6.18 tree the "resetting" part was missing.
In the pvops tree, this should work correctly through the fix_features
mechanism.

[-- Attachment #1.1: Type: text/plain, Size: 1585 bytes --]

We have implemented hugepage support for guests in following manner

In
 our implementation we added a parameter hugepage_num which is specified
 in the config file of the DomU. It is the number of hugepages that the 
guest is guaranteed to receive whenever the kernel asks for hugepage by 
using its boot time parameter or reserving after booting (eg. Using echo
 XX > /proc/sys/vm/nr_hugepages). During creation of the domain we 
reserve MFN's for these hugepages and store them in the list. The 
listhead of this list is inside the domain structure with name 
"hugepage_list". When the domain is booting, at that time the memory 
seen by the kernel is allocated memory  less the amount required for hugepages. The function 
reserve_hugepage_range is called as a initcall. Before this function the
 xen_extra_mem_start points to this apparent end of the memory. In this 
function we reserve the PFN range for the hugepages which are going to 
be allocated by kernel by incrementing the xen_extra_mem_start. We 
maintain these PFNs as pages in "xen_hugepfn_list" in the kernel. 

Now before the kernel requests for hugepages, it makes a hypercall HYPERVISOR_memory_op  to get count of hugepages allocated to it and accordingly reserves the pfn range.
then whenever kernel requests for hugepages it again make hypercall HYPERVISOR_memory_op to get the preallocated hugepage and according makes the p2m mapping on both sides (xen as well as kernel side)

The approach can be better explained using the presentation attached.

OK, I'll recheck bug in squeeze and report it separately.

Main problem for this bug is very high value of free memory when OOM
killer starts. In my tests it appear when about 300MiB was free. And it
kill not most 'badness' process, but runs repeatedly for few (or even
all) process. 

But, again, I'll recheck it in clean environment with reproducible
behavior and submit it.

I wasn't aware that this issue was present on Squeeze as well as Lenny,
there is no mention of that in the bug.

The two kernels have practically nothing in common wrt the Xen port
(Lenny was classic-Xen patch based and Squeeze is pvops based) so if you
are seeing something similar under Squeeze as well please file a
separate bug report.

(Note that only the OS in the specific VM which is exhibiting the
problem is relevant, so even if you are seeing the issue with a Lenny VM
hosted on a Squeeze dom0 that does not imply the bug is present in
Squeeze).

I'm afraid that at this point I do not have cycles to spend on the Lenny
issue. Unfortunately my best recommendation is not to balloon such
systems too aggressively or to use a more recent kernel (e.g. a backport
of the Squeeze kernel).

Ian.

They were posted on my personal website
http://www.hellion.org.uk/debian/test/
and referred to by
http://lists.xensource.com/archives/html/xen-devel/2010-08/msg01912.html
but I moved them to xen.org and just left a pointer on my website, I
didn't bother to announce this.

I'm afraid the necessary meta data is not present to allow them to be
used as an apt source so they are download+dpkg only.

Originally they were intended to simply verify that the issues people
were seeing related to changesets which had been excluded from the
Debian kernel.

I haven't decided if these are something I necessarily want to maintain
for the lifetime of Squeeze. For the moment I build them for my own
personal use and so I publish them, since I might as well do so, but
they are not a formal xen.org service or anything like that.

For something provided by xen.org I think we would more likely want to
track the latest xen.git#xen/stable-2.6.x.y branch rather than the
Debian packages.

Ian.

Please note this bug:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=595711

This behavior confirmed in lenny and squeeze. Kernel is very unstable
(compare to centos/suse) and cause OOM killer without any rational
reason.

We intend to publish debian and centos packages for the xen hypervisor
and tools, however the project is stalling a bit recently.
Hopefully those packages will be published in the next few weeks.

I have search the archives for reference to Ian Campbell's Debian binaries found at: http://xenbits.xen.org/people/ianc/


http://lists.xensource.com/archives/cgi-bin/namazu.cgi?query=http%3A%2F%2Fxenbits.xen.org%2Fpeople%2Fianc%2F&submit=Search!&idxname=xen-devel&max=20&result=normal&sort=score


I am wondering if the http://xenbits.xen.org/people/ianc/squeeze/ or http://xenbits.xen.org/people/ianc/sid/ HTTP folders can in some way be added to Debian's apt sources file?


Thanks.

Add a x86_mcinfo_reserve() function, to reserve space from mc_info.

With this method, we don't need to collect bank and globalinformation to a
local variable and do x86_mcinfo_add() to copy that information to mc_info.
This avoid copy and also we can be aware earlier if there is enough space
in the mc_info.

Also extract function that get global/bank information to seperated
function mca_init_bank/mca_init_global.

It's meaningless to get the current information in mce context, keep it here
but should be removed in future.

Also a flag added to mc_info, to indicate some information is lost due to OOM.

[Eads, Joshua Michael (S&T-Student)]

I have an HVM guest and I am trying to have a usermode program in Dom0 query the context (CPU registers, specifically) of the guest.  

I first tried using xc_domain_getcontext() in xenctrl.h but I haven't figured out what data structure ctxt_buf is that it returns.  Next, I have tried using xc_vcpu_getcontext() in xenctrl.h but so far it always returns -1 for failure.  For xc_vcpu_getcontext, I am passing in a vcpu number of 1 (I only have a single virtual CPU domU running) along with an unallocated vcpu_guest_context_t pointer.

Is this the right direction to pull guest registers, or is there another method I need to use to get the HVM guest context?

Thanks,
Josh

Hi all,

My Dom0 crashed if I use the first grub configuration, but is ok if I use
the following one.

kernel          /boot/xen-3.4-unstable.gz
module          /boot/vmlinuz-2.6.18.8-xen root=/dev/sda2 ro

kernel          /boot/xen-3.4-unstable.gz com1=9600,8n1 console=com1 iommu=1
module          /boot/vmlinuz-2.6.18.8-xen root=/dev/sda2 ro xencons=ttyS
console=tty0 console=ttyS0

I've attached the full boot trace. Below is a snippet of the crash region.
Does anyone have any idea what's going on?

Thanks and have a nice day.

If you are referring to the gplpv drivers, then I have only developed
with scsiport at the moment. Storport is only supported under 2003 and
later and I didn't want to maintain two versions of the same code. I'm
not yet convinced that storport will give any noticeable advantage over
scsiport for what we are doing.

xenvbd (scsi emulation of block device) and xenscsi (pvscsi scsi
passthrough) are both scsiport drivers, but xenscsi doesn't work at the
moment as it only worked with a slightly modified version of the 3.2
version of pvscsi. It will be incompatible with the 3.3 version. I will
update it once I get 3.3 installed on my dev box (waiting for some
Debian packages).

Thanks

James

Does anybody know if Storport is supported on XEN?  I only see references to SCSIPORT (i.e xenscsi.sys).

hi all,
  can anyone tell me what exactly the iret hypercall does?
and, is there any way to disable the fast system call handlers and use
normal system call handling?

Hi,

i am using two domains, which are internally connected by one virtual interface.

xendom1: Backend Domain without a physical interface
xendom2: normal Domain-U using xendom1 as a vif-Backend-Domain

 ---------      ---------
| xendom1 |    | xendom2 |
|         |    |         |
|  vif2.0--------eth0    |
|         |    |         |
 ---------      ---------

Then i add another virtual interface to xendom2.

 ---------      ---------
| xendom1 |    | xendom2 |
|         |    |         |
|  vif2.0--------eth0    |

Attached is a patch which extends vmxassist to handle two cases 
related to mode switching found while experimenting with different 
boot loaders.

The first case is use of the JMP instruction with memory location 
operands to complete a switch to protected mode. This patch adds 
emulation for this form of the JMP instruction to vmxassist.

The second case is where boot loader code does not save/restore a 
non-zero SS register across a protected mode traversal. 
Zeroing the SS register in vmxassist results in all sorts of problems 
in the domU after returning back to real mode. This patch stores 
segment register values before entering protected mode and correctly 
restores the old values (instead of an incorrect zero value) when 
reentering real mode.

Hello!

Just wanted to let everyone know Jiuxing  has populated a mercurial
tree (very kindly hosted by XenSource) with his code at the following site:

http://xenbits.xensource.com/ext/xen-smartio.hg

This contains the current source code for a xen infiniband frontend
and backend driver. The source code is in very preliminary stages
of development, just a proof of concept for now (works). We have
a long way to go.  We'd like to invite interested folks to take a look
and get involved in the continuing design and development as an
open-source community.

We will be putting up a Wiki page for this shortly on the Xen Wiki.
Stay tuned...

There is also a mailing list we set up for discussion on
virtualization of smart I/O in Xen at:

http://lists.xensource.com/cgi-bin/mailman/listinfo/xen-smartio

However, at Ian's request we're going to contain most discussion
to xen-devel itself.


thanks,
Nivedita

I am facing problems with debugging DomU.

I have made changes in the gdt table in the file head.S for Dom U. Because
of that the domain is crashing.

For debugging, I followed the steps mentioned in the file
/xen-unstable/tools/debugger/gdb/README. I also made changes in the
/xen/Rules.mk file and compiled domU with -g C flag.

However, as mentioned in the README file no
/var/xen/dump/<Domain-name>.<DomainID>.core file is generated.

Rules.mk file :
verbose     ?= y
debug       ?= y
perfc       ?= n
perfc_arrays?= n
domu_debug  ?= y
crash_debug ?= y

Am I missing something?

Thanks for replies.

Thanks for the info, Michael. Just wondering if this code has been checked 
into the Xen-unstable branch, or around when it would be checked in.
(I din't find any related checkin by searching at

Oops, I tried it only using a cross-compiler.  When I compiled
natively on ia64, it is still necessary to specify
LINUX_ARCH=ia64 on the make-line, else I get x86 configs.

I think the fix is to change in buildconfig/Rules.mk from

ifneq ($(ARCH),ia64)
  to
ifneq ($(XEN_TARGET_ARCH),ia64)

I'll roll this fix in at the next merge with xen-ia64-unstable.

Thanks very much!  I tried it and it works great!  Using
this, I have started committing files into the ia64 subdirs

I'll check it in tomorrow, and I'll make it set LINUX_ARCH
dependent on ARCH, like you did in your original patch...

No, it's not in my shell environment.  However, when I run make
to build for ia64 I run it as: 'make LINUX_ARCH=ia64 ...' and
I'm guessing make must export it to subshells.  If I add the
'echo', I do get ia64 in /tmp/xxxxxx and the ia64 hook scripts
do get run.

But if I build (for xen/x86) with just 'make', nothing gets
echoed to the file and, as you pointed out, no hook script
gets run.  But that's the default behavior we want, correct?

I suppose it would be nice if on ia64 just 'make' did the
right thing, e.g. set LINUX_ARCH=ia64 without the need to
specify it on the command line.  In that case, adding it
to all the calls to mkbuildtree is necessary.  How do
I set LINUX_ARCH in Rules.mk so that it is set to 'xen'
if x86 (or x86_64) and the architecture it is running on
(e.g. ia64) otherwise?

So I think the patch is OK as is... I've built successfully
for both x86 and ia64... but I can still change it and
resubmit if you prefer the other way.

Thanks,
Dan

Rules.mk is fine.  What I meant is that LINUX_ARCH won't get
passed to mkbuildtree unless you add it to its environment.
I confirmed this now by adding this to mkbuildtree:
echo ${LINUX_ARCH} >>/tmp/xxxxxxxx
LINUX_ARCH is empty and thus your hook script won't run.  Maybe
you have LINUX_ARCH set in your shell environment where you ran
make?  Odd...

I'm not sure I follow... I don't know exactly how make or bash
work wrt to exporting... I didn't explicitly export LINUX_ARCH
but it seems to be known by mkbuildtree and all the mk.linux's
anyway.  (I successfully built for x86 and ia64 with the
patch.)

Or are you suggesting I *not* define it in buildconfigs/Rules.mk
so as to avoid polluting the environment?

You have to export LINUX_ARCH to the script.  We don't want to
unconditionally polute the environment of all the commands we
run, so you'll have to add it to all the calls to mkbuildtree.

I think I'd prefer xen-mkbuildtree-{pre,post} as the name of the scripts
to run, but not too fussed about that...

Ok, let's go with the pre/post link scripts for now, but I think
it would be good to make our changes work when building non-x86/non-xen.

I've just used this for convenience.  The defconfigs in
Linux/ia64 cause prompting and the config change required for
Xen/ia64 support (because it is transparently paravirtualized)
is adding "CONFIG_XEN=y".  But I can easily put the output
of make oldconfig in the xen defconfig file if the
preference is to have no prompting (thus the "yes" pipe
is removed from the previously posted patch).

Dan

Do the changes have no impact to non-Xen non-x86 kernels?
Since xenlinux/ia64 is transparently paravirtualized,
the changes looked like they might be xen-specific, and
xenlinux/ia64 has been running out-of-tree without any
of those changes, the script moves them aside.  If there's
no impact, I can move them back in (but will probably
do so slowly for testing purposes).

In any case, drivers/xen definitely is not yet fully
archdep, so I need to use the pre- or post-mkbuildtree
to do some patching in the short term.  Agree in the longer
term, these files should be empty but if you don't mind
greatly, having the archdep hooks there will probably
make things easier for arch's for now.

I think it's preferable to have default config files which don't cause
any prompting.

Also if people upgrade, they probably want to be prompted on any new
options.  If not, then let's get the default behaviour for "make
oldconfig" changed upstream...

I guess, to answer <ret> (choose default) to any questions oldconfig throws

This mechanically does the same as manually hitting

Please define LINUX_ARCH in buildconfigs/Rules.mk and use that where
we run make ARCH=xen.
If you can name your config file xen0_defconfig_ia64 and use
LINUX_ARCH for the path, then you won't need to duplicate the config
file code.
Please also change all mk.linux files.

Why do you need to move these out of the way in the first place?  If
any of the changes we've made break ia64, then we should cleanup our
changes.

[-- Attachment #1: Type: text/plain, Size: 1493 bytes --]

Attached is an (ugly but relatively simple) patch that allows
Xenlinux/ia64 to be built using the linux "-sparse" tree
methodology (once I populate some files in the -sparse tree).

The changes are not dramatic and I think they can be done
much more cleanly, but I'm not a build expert so would
appreciate improvements from those more comfortable with
the Xen build environment... and perhaps it can be
made more generic so the ppc guys can benefit too.

The primary changes are:
1) wherever a make is done with ARCH=xen, this needs
   to be converted to ARCH=ia64.  (This can probably
   be done as ARCH=$(XENARCH) or something like that
   but I'm not sure how to do it without requiring x86
   and x86_64 builds to specify XENARCH= at build time.)
2) A sequence of mkbuildtree "massage" commands need to
   be executed before mkbuildtree does its linking thing.
   Perhaps this could be done as:
    if -e mkbuildtree.prelink.$XENARCH
        mkbuildtree.prelink.$XENARCH
   Though ia64 doesn't need it, maybe also add a "postlink"
   equivalent?

There is also one change because the ia64 defconfig filename
is different.  I can change this filename to conform with
the existing convention but perhaps the defconfig pathname
could be set as part of the prelink file?

Could someone with the necessary build knowledge make
the improvements and commit this please? Let me know if/when
it goes in and I will populate the ia64 -sparse branches.

Thanks,
Dan

Hi,

has anybody tried linux-iscsi-4.0.2 with linux-2.6.11-xen0?
scsi-transport-iscsi failed to compile due to different structure
definitions in scsi_transport_iscsi.h
Using scsi-transport-iscsi from linux-2.6.11-xen0 distro I was able
to open iscsi session. However, there is tons of kernel errors like below.
Any ideas how to cure it?

Correct. The DOM0 interface treats "non-existing" ssidref configurations 
now
differently (sets them to 0 instead of ffffffff).

Hello ，
    I am interested in Xen project,but  I am a stranger .
    I have got the code of Xen project,but there is no explanation in the lines ,I can not understand the code ,

    Could you give me a document about  software construction of Xen project ,including how many modules ,how these modules are organised and etc.

   Who have designed the CPU modules ,can you shou me a light on how you organise the CPU modules?

Not that much has been checked in since then. You could try backing out 
the local APIC code changes (checked in on 16th April) but even that 
seems unlikely to break the floppy driver, I think.

Thank you sir, I will check that. I did do another build with 12apr05 xen-unstable and it did not have the same symptom/problem, xen-unstable changed around 16-17apr05, to expose this symptom on a thinkpad. Will look deeper.

Have you tried messing with the 'floppy=' parameter on the kernel
command line?
See Documentation/floppy.txt

Alternatively, just config the driver out of your kernel, to confirm
that this is what is causing the hang.

We use the floppy driver in PIO rather than DMA mode, and this is must
be causing the probe code to get confused under some circumstances.
(thinkpad floppy drives are somewhat notorious, and there's lots of work
arounds in the probe code)

I like all the patches. Any comments from anyone else?

I guess there's enough fixes in 2.0-testing to warrant a release,  but
I'd like to leave all the patches in testing for a couple of days to get
exercised.

[Adam Heath]

I spent last night and this morning splitting the single patch I had, into 13
separate patches.  Most are build system tweaks(DESTDIR, parallel make,
INSTALL, proper target depends).  Also, proper PIC support in the libs, and a
few other things.

Below is the meta-info that my patch oriented build system maintains.  I'll be
sending each patch as a separate mail(I apologize for the mail flood ahead of
time).

ps: I decided to split out these patches, and send upstream, before uploading
    my deb packages.  If possible, I'd like to have these applied, and a new
    version rolled based on them.

pps: These are generated against 2.0.3.

Description: use DESTDIR correctly
 Standard makefiles always attempt to install to the root(/).  Setting
 DESTDIR is the normal way to install to an alternative location.
 .
 Setting prefix has the possibility of breaking programs, as the prefix
 may have been embedded inside a compiled binary.

All these problems are to be expected - the guest can't make privileged 
access to the machine's hardware so updating microcode, clock, etc won't 
work. I'm not actually sure what "keytable" does but it doesn't look like 
it's needed ;-), gpm is definitely not needed.

It's nothing to worry about - you should just disable these services so 
that they don't get run. e.g. on Redhat something like

# chkconfig --del servicename

for each service.  Or use you favourite console / GUI admin tool.

As mentioned in another post, the microcode update seems to be trying to 
load the module for the wrong kernel version (which is odd). Even if it 
were the right version, it still wouldn't work...

Cheers,
Mark

It's actually xenU I want to test it in (but compiling under xen0), and a make says this:

Note: using kernel source from /lib/modules/2.6.7-xen0/build containing
kernel version 2.6.7

Note: using kernel config from /boot/config-2.6.7-xen0

So i set TOPDIR too, and also had to patch iscsi-id.c to fix these two errors:

iscsi-id.c:90: error: too few arguments to function `sysfs_open_class_device'
iscsi-id.c:94: error: too few arguments to function `sysfs_open_class_device'

by changing the calls to sysfs_open_class_device_path. hope that's the right thing to do. I must have a different version of sysfs (debian version is 1.1.0-1)

'make ARCH=xen' seems to do the right thing, but 'make ARCH=xen install' says:

Installing iSCSI driver for Linux 2.6.7-xen0

doh!

then I replaced all occurences of 'shell uname -r' in the makefile with 'shell echo 2.6.7-xenU'

and it compiles finally. The only problem is that I just did a bk pull and enabled SCSI in xenU, and now the kernel won't compile. i've attached the output of 'make linux26' (but it got rejected so i'm posting it without), the errors are to do with undefined references to 'direct_remap_area_pages'. Do you think that it is to do with the latest bk pull or to do with me enabling device drivers in an unprivileged kernel?

i'll get there eventually!

thanks

James

Brian,

I've done basically the same thing with the Xen FAQ. I've watched the 
list and updated the FAQ as new questions came along. In order to 
centralize the Xen documentation, won't you pull the Xen FAQ into the 
wiki? It can be found here:
http://xen.epiuse.com/xen-faq.txt

Once you're done that I'll replace the FAQ with an automatic redirect 
to your page. The FAQ was last updated about 3 months ago (Sorry 
everybody about that! Work got a bit hectic).

Jan
