[Qemu-devel] [RFC PATCH 0/9] ISA 3.00 KVM guest support

[Qemu-devel] [RFC PATCH 0/9] ISA 3.00 KVM guest support

[Sam Bobroff]

Because KVM will soon provide the necessary infrastructure for KVM guests to
run on POWER9 CPUs, we can now start exploiting this new functionality from
QEMU. See:
https://lists.ozlabs.org/pipermail/linuxppc-dev/2017-January/153433.html

This work is not yet complete but it is functional and is presented for early
review. It overlaps in some places with current work supporting the same guests
under full emulation.

This set aims to support only the following scenarios:
* A POWER9 host running in radix mode, running a guest in radix mode.
* A POWER9 host running in hash mode, running a guest in hash mode.
* A POWER9 host running in hash mode, running a guest in legacy(+) mode.
(+) Where legacy means that the guest does not support ISA 3.00.

Hash or radix mode for the host is controlled via the "disable_radix" kernel
command line parameter: the host will use radix unless disable_radix is given.
For the guest it should be automatically selected to match the host.

Bad legacy guests: There are some recent kernels (e.g. 4.9) that will, when run
as a KVM guest and if the ibm,pa-features entry in the device tree has the
Radix MMU bit set, attempt to initialize the MMU as if they were a host (which
will cause them to crash). To avoid exposing this problem, the Radix MMU bit
is removed from ibm,pa-features when a legacy guest is detected.

Prerequsites:
* This set is based on current QEMU master, but relies on some work already posted here:
https://lists.gnu.org/archive/html/qemu-devel/2017-01/msg02527.html
Specifically patches 1..4 which set up the new CPU and MMU models.

Notes:
    * Migration/snapshots are not yet investigated.
    * If the host cannot support the guest (e.g. radix host and a legacy guest)
      then the guest will crash but QEMU should probably terminate with a
      descriptive message.

[Qemu-devel] [RFC PATCH 1/9] spapr: fix off-by-one error in spapr_ovec_populate_dt()

[Sam Bobroff]

The last byte of the option vector was missing due to an off-by-one
error. Without this fix, client architecture support negotiation will
fail because the last byte of option vector 5, which contains the MMU
support, will be missed.

It took a while 'til I understood the encoding / length calculation of
the property here, but I think you're right. According to LoPAPR the
total length of the property is n+2 where n is the value of the first
byte. Since n is vec_len-1 in the QEMU code, vec_len+1 is the right
value for the property length.

This is a correct fix regardless of the rest of the series, so I've
applied it to ppc-for-2.9.

I noticed this working on another series and ended up with the same fix.

The patch doesn't apply cleanly for me though due to the "spapr_ovec_ruler"
reference. But, assuming that is unrelated to this series:

You're corret, that line is unrelated.

[Qemu-devel] [RFC PATCH 2/9] Update headers using update-linux-headers.sh

[Sam Bobroff]

This provides some new definitions needed by ISA 3.00 guests.

It is a large change because this is the first import since
some kernel header files have become autogenerated.

Note: update-linux-headers.sh currently generates a change that
(incorrectly) removes virtio_mmio.h and the change has been manually
adjusted to prevent that.

Looks like the contents of asm-arm/unistd.h has been moved to two new
files, unistd-eabi.h and unistd-oabi.h, but they are not part of your
patch. I guess update-linux-headers.sh needs a fix for that?

Ah thanks! I'll look at it.

Should I try to fix the other problem with update-linux-headers.sh at
the same time? (I'm referring to the issue I noted in the commit
message, about virtio_mmio.h)

Cheers,
Sam.

It's no great problem for this RFC series, but in general please
include the SHA of the kernel commit you're updating to, and, if it's
not in Linus's tree yet, a link to a repo containing the kernel
version in question.

[Qemu-devel] [RFC PATCH 3/9] spapr: Add ibm, processor-radix-AP-encodings to the device tree

[Sam Bobroff]

Use the new ioctl, KVM_PPC_GET_RMMU_INFO, to fetch radix MMU
information from KVM and present the page encodings in the device tree
under ibm,processor-radix-AP-encodings. This provides page size
information to the guest which is necessary for it to use radix mode.

IIUC this info is ready for direct inclusion in the device tree:
i.e. it's big-endian.  That absolutely needs a comment in the
structure.  I'm also not sure it's a good idea, since I assume the TCG
POWER9 code will eventually need to access this information directly
to implement the radix MMU.

Might be clearer to make this data structure native and do the BE
conversion when generating the device tree.

I'm not sure this belongs in CPUPPCState.  New fields should generally
be added to PowerPCCPU ("cpu") rather than to CPUPPCState ("env")
unless they need to be directly accessed from TCG generated code.

But even more, AFAICT this should vary only with the CPU type/model,
not with the individual CPU instance.  So this information could
probably go into the CPU class structure instead of the instance.

Yes, there are a lot of things that don't obey those rules already -
that's because a lot of stuff hasn't been converted since the new QOM
stuff was introduced.  But we shouldn't make it any worse with new
patches.

Putting the data in the class would avoid this ugly messing with a
static local, for one thing.

Please rename this cap_mmu_hashv3 to avoid confusion.

[Qemu-devel] [RFC PATCH 5/9] spapr: Only setup HTP if necessary.

[Sam Bobroff]

Because KVM cannot support radix and hash modes concurrently, QEMU can
avoid allocating a hash page table if KVM supports radix mode.

This isn't quite right, it's doing the HPT handling based on whether
or not we *can* do RPT rather than whether we *are* doing RPT.

It'll mostly work for now, while only radix-on-radix and hash-on-hash
are supported, but that won't be true forever.

It will already be wrong if, for example, you tried to run a POWER8
TCG guest on a host that happened to be a POWER9 in radix mode.

[Qemu-devel] [RFC PATCH 6/9] spapr: Add h_register_process_table() hypercall

[Sam Bobroff]

Both radix and hash modes require guests to use
h_register_process_table() to set up the MMU. Implement it using the
new KVM ioctl KVM_PPC_CONFIGURE_V3_MMU.

This hypercall is also necessary for fully emulated guests, so it will
need to be reworked to integrate with Suraj's TCG patchset.

Ewwww.. a static local?  Store this info in sPAPRMachineState instead;
chances are you'll want it in other places eventually anyway (even if
only for debugging).

No #defines for the bits in the hcall arguments?

[Qemu-devel] [RFC PATCH 7/9] spapr: Set ISA 3.00 radix and hash bits in OV5

[Sam Bobroff]

Set new option vector 5 bits to indicate KVM support for in-memory
radix or hash modes and related options. The existing logic will
propagate the results back to the guest in the device tree. This
allows guests to perform client architecture support negotiation on
the new radix and hash MMU modes and will cause ISA 3.00 guests to
start using h_register_process_table().

What are these last two bits about?  AFAICT nothing has been
implemented for them, and they shouldn't be set until that's the case.

[Qemu-devel] [RFC PATCH 8/9] spapr: Advertise ISA 3.0 MMU features in pa_features

[Sam Bobroff]

Set the default ibm,pa_features bits for ISA 3.0.

Providing the radix MMU support bit in ibm,pa-features will cause some
recent (e.g. 4.9) kernels to attempt to initialize the MMU as if they
were a radix host, which will cause them to crash. So, if a guest
performs a client architecture support call without indicating ISA
3.00 support (specifically, if they do not indicate that they support
either new radix or new hash mode) then the radix bit is removed from
ibm,pa-features to avoid triggering the bug.

This is a little bit icky, since cas_legacy_guest_workaround isn't
explicitly reset when you have a non-CAS reboot.  In practice it will
probably work, because it is reset on every CAS, but it does mean that
the pre-CAS value can depend on the previous guest booted which is
conceptually incorrect.

I think it would be preferable to determine whether you have a legacy
guest at the point you need it, directly from spapr->ov5_cas.  The CAS
core already manages resets of that correctly across both CAS and
non-CAS reboots.

[Qemu-devel] [RFC PATCH 9/9] spapr: Small cleanup of PPC MMU enums

[Sam Bobroff]

The PPC MMU types are sometimes treated as if they were a bit field
and sometime as if they were an enum which causes maintenance
problems: flipping bits in the MMU type (which is done on both the 1TB
segment and 64K segment bits) currently produces new MMU type
values that are not handled in every "switch" on it, sometimes causing
an abort().

This patch provides some macros that can be used to filter out the
"bit field-like" bits so that the remainder of the value can be
switched on, like an enum. This allows removal of all of the
"degraded" types from the list and should ease maintenance.

Ok, I've merged 1/9 and reviewed the rest.

So, it's reasonable to avoid migration for now.  I'm even ok merging
something without migration support *IF* it isn't a silent failure:
i.e. it must have at least a stub that will fail the migration early
if it's in a mode that's not supported.

Uh, yes, that would certainly be better.

It would help if you pushed this as a tree with all prerequisites somewhere
(github?); same about the kernel which has bits which this patchset is
using. Thanks.
