The goal here is to build ACPI tables for PVHv2/HVMlite guests while reusing existing
hvmloader's ACPI builder code. The builder is provided as a library in tools/libacpi.
This is version 3 of the series, see individual patches for changes. It can
be fetched from git://oss.oracle.com/git/bostrovs/xen.git:acpi_v3
The series is probably still gated by lack of an ACK from Lenovo for the
relicensing patch (included here as patch 1).
Boris Ostrovsky (19):
acpi: Re-license ACPI builder files from GPLv2 to LGPLv2.1
acpi/hvmloader: Collect processor and NUMA info in hvmloader

acpi/hvmloader: Replace mem_alloc() and virt_to_phys() with memory ops
acpi/hvmloader: Translate all addresses when assigning addresses in
ACPI tables
acpi/hvmloader: Link ACPI object files directly
acpi/hvmloader: Include file/paths adjustments
acpi: Move ACPI code to tools/libacpi

ACPI builder is currently distributed under GPLv2 license.
We plan to make the builder available to components other
than the hvmloader (which is also GPLv2). Some of these
components (such as libxl) may be distributed under LGPL-2.1
so that they can be used by non-GPLv2 callers. But this
will not be possible if we incorporate the ACPI builder in
those other components.
To avoid this problem we are relicensing sources in ACPI
bulder directory to the Lesser GNU Public License (LGPL)
version 2.1

Components that wish to use ACPI builder will need to provide their own
mem_alloc() and virt_to_phys() routines. Pointers to these routines will
be passed to the builder as memory ops.
Signed-off-by: Boris Ostrovsky <boris.ostrovsky@oracle.com>

Changes in v3:
* Constified more function call parameters
* Added a free() nop hook in util.c

ACPI sources will be available to various component which will build
them according to their own rules. ACPI's Makefile will only generate
necessary source files.

In prepearation to moving acpi sources into generally available
libacpi:
1. Pass IOAPIC/LAPIC/PCI mask values via struct acpi_config
2. Modify include files search paths to point to acpi directory
3. Macro-ise include file for build.c that defines various
utilities used by that file. Users of libacpi will be expected
to define this macro when compiling build.c
Signed-off-by: Boris Ostrovsky <boris.ostrovsky@oracle.com>

Changes in v3:
* Instead of adding x86.h pass APIC/IOAPIC info via acpi_config parameter.
* Use <> instead of "" for include directive

PVH guests require DSDT with only ACPI INFO (Xen-specific) and Processor
objects. We separate ASL's ACPI INFO definition into dsdt_acpi_info.asl so
that it can be included in ASLs for both HVM and PVH2.
Signed-off-by: Boris Ostrovsky <boris.ostrovsky@oracle.com>
---
Changes in v3:
* Added comment to dsdt_acpi_info.asl indicating that the structure
there must match struct acpi_info
* Use QEMU_NONE in mk_dsdt.c
* Makefile tweaks

Provide ability to load multiple ACPI modules. Thie feature is needed
by PVHv2 guests and will be used in subsequent patches.
We assume that PVHv2 guests do not load their ACPI modules specified
in the configuration file. We can extend support for that in the future
if desired.

libxl__domain_make() may want to use b_info so we should set defaults
a little earlier.

Changes in v3:
* Some constification of call parameters
* Format adjustments
* New acpi_mem_free hook (a nop)
* Changes in init_acpi_config() to deal with constified acpi_numa's
pointers (initialize pointers as temp variabales)
* Add '-include acpi' directive in Makefile to make sure acpi
target is built before build.o dependencies are processed
(specifically, ssdt_*.h files need to exist)

... the body of this function was actually a brief comment,
clarifying why this does nothing.

Why uint16_t? Legacy APIC IDs in MADT are in an 8-bit field, and
x2APIC IDs require 32 bits. Depending on whether we want to be
able to re-use the same function for x2APIC support (once that
gets added) the return type should change accordingly. (But if we
were to re-use it, I guess a second parameter would then also be
needed.)
And then - down the road you're not planning to build a shared
library using this interface? Otherwise we'd need to consider some
compatibility aspects.

Hadn't I seen you switch to use intermediate files with all this output
redirection in v2? Did that get lost, or do I misremember?
Everything else looks fine.

How is this (or really the rules using this directory) supposed to work
when other than "all" gets built?
> vpath iasl $(PATH)

And how is the temporary directory going to get cleaned up when
interrupting make? I think you really should use a subdirectory
underneath the build directory, which then can stay there until
"make clean". And then you can also use mv instead of cp below,
or even move-if-changed.

There not being (or getting added) any users of these in libacpi/, I
wonder how this is related to the subject of the patch. If this is
data that only libxl needs for its own purposes, then surely this
shouldn't get added to struct acpi_ctxt, but should be a libxl
private extension of that structure.

No good reason for uint16_t, should be uint8_t.
I think deciding on how interface will look for x2APIC should be
deferred until when we support it.

No specific plans for now, the objects are expected to be built and
linked directly to whoever wants to use this (so libacpi is somewhat of
a misnomer, similar to libelf).

I realize it's a somewhat weak argument but only 'all' and 'clean'
targets are supposed to be used. In fact I was thinking about explicitly
making a check for targets.

The reason I am doing this in /tmp and use tmp_XXXXX as template is
because I found that at least one old versions of iasl has a bug where
it can't process path that has a '.' in it. It drops anything after the
dot, presumably because it thinks it's file suffix.
This is true on fedora12 (2009), which is what we still use as build
environment. I know that fedora 18 doesn't have this problem but I don't
know at which point this got fixed. (Interestingly enough, I tried to
build from F12's sources for iasl and could not reproduce this. Now, i
built with new tools so perhaps the bug is not in iasl itself but in
something like yacc, which is used for the build).
I don't think we have any requirement on supported iasl version so I am
not sure we can ignore this error.

Hmm, that would be quite limiting in case one wants to analyze a
problem with just a single build step. (On the hypervisor side I,
every once in a while, find it helpful to be able to compile individual
files into .o, or even produce the intermediate .i or .s.)

That . is a leading one, as in ./path/file.ext? If so, why can't this be
made path/file.ext? The leading ./ shouldn't be necessary after all.
Also this part of your answer doesn't address the cleanup aspect at
all. (And btw., thinking about it again I don't see the need for a
subdirectory. We have ample room to name the intermediate files
suitably without causing any name collision.)

That's one option; I'd prefer
struct libxl_acpi_ctxt {
struct acpi_ctxt ctxt;
...
};
though, together with whatever equivalent to container_of() exists
in libxl.

Yes.
I tried to figure out a way for Makefile to always execute a rule when
before it exits but didn't find anything. You can do it as a *first*
rule (with "-include <file>") but not as a final one.
My only defense here (again, pretty weak) is that making libacpi 'all'
target is pretty fast.

No, not a leading one. Inside a name:
Expected:
[root@ovs104 libacpi]# mkdir -p /tmp/root/xen.git
[root@ovs104 libacpi]# iasl -vs -p /tmp/root/xen.git/dsdt_anycpu -tc
/tmp/dsdt_anycpu.asl &>/dev/null
[root@ovs104 libacpi]# ls -R /tmp/root/
/tmp/root/:
xen.git
/tmp/root/xen.git:
dsdt_anycpu.aml dsdt_anycpu.hex
[root@ovs104 libacpi]#
Fedora 12:
[root@ovs104 libacpi]# mkdir -p /tmp/root/xen.git
[root@ovs104 libacpi]# ~/iasl.f12 -vs -p /tmp/root/xen.git/dsdt_anycpu
-tc /tmp/dsdt_anycpu.asl &>/dev/null
[root@ovs104 libacpi]# ls -R /tmp/root/
/tmp/root/:
xen.aml xen.git xen.hex
/tmp/root/xen.git:
[root@ovs104 libacpi]#
I tried escaping the dot, putting path in quotes, etc. but without any
success.

Again, not the greatest way to deal with this, but we will leave temp
directory in /tmp on interrupts. (And on error I could have added an
error handling target but decided not to do that so that it's easier to
debug the error).

That, in fact, is what I initially had --- I just added an extra temp
suffix to intermediate files during a build. And right before sending
the series I figured I'd give it a spin on our build server. Big mistake!
So I agree that this is not the best solution but I haven't come up with
anything better.

Yes, this is better. I don't see it defined in libxl but I can define
one myself.

Big mistake? You leave me curious, but unable guess.

It's called CONTAINER_OF. See tools/libxl/CODING_STYLE, and/or the
output of something like `git grep -i contain tools/libxl'.

Apparently it doesn't like any dots:

This seems to suggest that it looks for the last dot, not the first
one.
If you provide a filename which has an "extension", as it seems to
expect, does it DTRT ?

Indeed!
In fact, I can just append a dot to the name:
[root@ovs104 tmp]# mkdir -p /tmp/root/xen.git
[root@ovs104 tmp]# ~/iasl.f12 -vs -p /tmp/root/xen.git/dsdt_anycpu -tc
/tmp/dsdt_anycpu.asl &>/dev/null
[root@ovs104 tmp]# ls -aR /tmp/root/
/tmp/root/:
. .. xen.aml xen.git xen.hex
/tmp/root/xen.git:
. ..
[root@ovs104 tmp]# ~/iasl.f12 -vs -p /tmp/root/xen.git/dsdt_anycpu. -tc
/tmp/dsdt_anycpu.asl &>/dev/null
[root@ovs104 tmp]# ls -aR /tmp/root/
/tmp/root/:
. .. xen.aml xen.git xen.hex
/tmp/root/xen.git:
. .. dsdt_anycpu.aml dsdt_anycpu.hex
[root@ovs104 tmp]#
With that I can go back to my original version where I don't need to
have a temp directory at all.
Thanks Ian.

I think it would be less weird to append a dot and then an actual
extension with some letters or something. I'm not sure what the
extension ought to be but just a dot is going to be weird and
confusing.

Yes, I will append some sort of a suffix and add a comment explaining
why it is needed.

Didn't you ask to test with a relative path?
(Not this this is needed anymore, now that Ian suggested a solution).

Yes, and I gave an example of what I meant: dir/name.ext; no
./ or ../ or alike.

Hi Bros,
It looks like you forgot to add 'C_SRC-$(CONFIG_X86)' here. Will you add
it in your next version?

I know I said that I'd do it but then I realized that it would probably
make more sense to add this macro when a non-x86 target is first
introduced (which I believe is patch 3 in your series). It's a one-line
change IIRC so it shouldn't be too disruptive to your series.
I should have mentioned it when I posted v3 of my patches, I apologize
for forgetting it.

So I looked again at commit 801d469ad8b2b88f669326327df03d03200efbfb
(which is the patch from Lenovo) and it only does 2 things (assuming I
parsed ASL correctly):
* Adds _PIC method
* Controls and describes legacy PCI interrupt routing. This
functionality has actually been moved into mk_dsdt.c and so this ASL
code is now generated.
Neither of these two things is used by libxl so technically we may not
need the ACK from Lenovo. OTOH, we may forget about this restriction in
the future and accidentally include those two later.

Does it mean this series may not be in Xen 4.8? If so, this will also
delay other series such as the ACPI guest support for ARM.

I would like to see this and the subsequent ARM series in 4.8 -- it is
still possible we get an ack from Lenovo any time, but the issue is out
of our control at the moment. It's just one unfortunate incident in open
source software development. Sigh.

One option could be to provide a 'gpl_all' (or some such) target in
libacpi in addition to 'all' and that target will be careful about not
including these small un-ACKed portions of the code.
It will be ugly though.

I agree that it is not nice, but it would help us to get this features
(and the other ones that depend on it) in Xen 4.8. Otherwise we would
have to wait another 6 months to get those features.

If Jan (who is/will be libacpi maintainer) agrees to this it can be
easily added.

I'd like to make this dependent on how ugly it ends up being.

Something along the lines of this (attached as well to prevent line

Maybe even without changes to mk_dsdt.c

Looks reasonable with some polishing (GPL=y on the make lines and
using C_SRC-$(GPL) and CSRC-y).

But isn't that the critical part? And - what functionality do we lose
without that code? There's no point in generating something that's
of no practical use.
And then there's the question of whether excluding things from the
build, but having them present in the sources actually helps.

Not necessarily since we'd use --gpl option only for
dsdt_anycpu_qemu_xen, dsdt_anycpu and dsdt_15cpu and these files are not
used by the non-GPL caller, which is libxl (it only wants dsdt_pvh).
Of course, this is what we have currently.

We don't lose any functionality (again, currently). In fact, this
indirectly prevents us from generating unnecessary files listed above.
> And then there's the question of whether excluding things from the

The main reason for this whole relicensing debacle is to prevent non-GPL
binaries from linking against GPL objects, and this patch allows us to
do that. Yes, there will be be two non-LGPL files (dsdt.asl amd
mk_dsdt.c, which I will revert back to GPL) in an otherwise LGPL
directory but that's an in-convenience and not a license violation.

Right - and with the goal to guard against future changes I think
we'd better not omit those parts.

Agreed - I got the sense of the check in mk_dsdt.c the wrong way
round.

Well, if linking is all this is about, then it's fine of course. I'm just
not a license expert, so we'd need this acked by someone who is
more familiar with the differences and implications.

I think Ian and Lars (added both here) would be the most experienced in
this matter.
I could move these two files into tools/libacpi/gpl subdirectory to
emphasize their special licensing.

It is all about linking. The terms of the GPL "spread" to derivative works
through both “dynamic” and “static” linking of binaries only. So you can
have one directory, which contains GPL and non-GPL licensed files, and not
suffer GPL-contagion as long as you can guarantee that the binaries
produced are of a specific license and you only link compatible binaries
with each other. Of course that is brittle and error prone.

Has it been
a) moved,
b) re-implemented in a different language using the ASL code as template,
or
c) implemented in C based on the ACPI spec?
Given that mk_dsdt.c is C and the original contribution is entirely ASL
(note that acpi_dsdt.c was generated from the ASL), a) does not appear to
be the case.
b) can probably not be excluded, in which case it may be safer to keep
mk_dsdt.c as GPL. But it would be a grey area.
If we knew for sure or it is plausible enough that it was c), then
mk_dsdt.c does not need to be GPL. And then the remaining Lenovo code in
dsdt.asl may be simple enough to not be copyrightable.
Whatever the answer, I would like to get Ian's opinion.
And it is still preferable though to have the entire component in LGPL and
to get a Lenovo ACK.

That would definitely make things easier and avoid any future mistakes
which lead to licensing issues.
Another general comment is that the component should have a COPYING file
and maybe a README.source file in the new component (that will make future
forensics easier).

Lars

_S5 object still exists but it's content has been modified by subsequent
non-Lenovo changes so I think we can not worry about lines 20-30.
But lines 30-43 are still present in current code.

Both hand-crafted and mk_dsdt-generated ASL file are *conforming* to
ACPI spec but the values (i.e. the topology that the ASL file describes)
are specifically chosen so I don't think (c) is the right answer.
Having said that it is entirely plausible that the author of the patch
ran iasl on his machine and took the output from it to produce the
patch, possibly with minor tweaks. But we, of course, don't know for sure.

I'll add a COPYING file (we already have a README).

Are we really having this much trouble over 13 lines ? Do we have
someone (who hasn't read the existing code) who could write 13 lines
of DSDT ?
Ian.

This is a bug fix (it implements section 5.8.1 of the spec, to be exact)
and presumably anyone with basic ASL knowledge would have been able to
write it.
But we'd still have to deal with mk_dsdt.c which is where the second,
larger, chunk of Lenovo patch went.
