RH-MergeRequest: 176: Enable KVM AMX support
RH-Commit: [13/13] 38f147c911258e84e01336271ebd23a1c24371fc
RH-Bugzilla: 1916415
RH-Acked-by: Cornelia Huck <cohuck@redhat.com>
RH-Acked-by: Igor Mammedov <imammedo@redhat.com>
RH-Acked-by: Paolo Bonzini <pbonzini@redhat.com>
Some AMD processors expose the PKRU extended save state even if they do not have
the related PKU feature in CPUID. Worse, when they do they report a size of
64, whereas the expected size of the PKRU extended save state is 8, therefore
the esa->size == eax assertion does not hold.
The state is already ignored by KVM_GET_SUPPORTED_CPUID because it
was not enabled in the host XCR0. However, QEMU kvm_cpu_xsave_init()
runs before QEMU invokes arch_prctl() to enable dynamically-enabled
save states such as XTILEDATA, and KVM_GET_SUPPORTED_CPUID hides save
states that have yet to be enabled. Therefore, kvm_cpu_xsave_init()
needs to consult the host CPUID instead of KVM_GET_SUPPORTED_CPUID,
and dies with an assertion failure.
When setting up the ExtSaveArea array to match the host, ignore features that
KVM does not report as supported. This will cause QEMU to skip the incorrect
CPUID leaf instead of tripping the assertion.

Commit [2] broke original '\0' padding of OEM ID and OEM Table ID
fields in headers of ACPI tables. While it doesn't have impact on
default values since QEMU uses 6 and 8 characters long values
respectively, it broke usecase where IDs are provided on QEMU CLI.
It shouldn't affect guest (but may cause licensing verification
issues in guest OS).
One of the broken usecases is user supplied SLIC table with IDs
shorter than max possible length, where [2] mangles IDs with extra
spaces in RSDT and FADT tables whereas guest OS expects those to
mirror the respective values of the used SLIC table.

bdrv_subtree_drained_end() requires the caller to hold the AioContext
lock for the drained node. Not doing this for nodes outside of the main
AioContext leads to crashes when AIO_WAIT_WHILE() needs to wait and
tries to temporarily release the lock.

RH-Commit: [1/3] 1a1fe37f8d8f0344dd8639d6cc9d884d1aff9096

bdrv_refresh_limits() recurses down to the node's children. That does
not seem necessary: When we refresh limits on some node, and then
recurse down and were to change one of its children's BlockLimits, then
that would mean we noticed the changed limits by pure chance. The fact
that we refresh the parent's limits has nothing to do with it, so the
reason for the change probably happened before this point in time, and
we should have refreshed the limits then.
Consequently, we should actually propagate block limits changes upwards,
not downwards.  That is a separate and pre-existing issue, though, and
so will not be addressed in this patch.
The problem with recursing is that bdrv_refresh_limits() is not atomic.
It begins with zeroing BDS.bl, and only then sets proper, valid limits.
If we do not drain all nodes whose limits are refreshed, then concurrent
I/O requests can encounter invalid request_alignment values and crash
qemu. Therefore, a recursing bdrv_refresh_limits() requires the whole
subtree to be drained, which is currently not ensured by most callers.
A non-recursive bdrv_refresh_limits() only requires the node in question
to not receive I/O requests, and this is done by most callers in some
way or another:
- bdrv_open_driver() deals with a new node with no parents yet
- bdrv_set_file_or_backing_noperm() acts on a drained node
- bdrv_reopen_commit() acts only on drained nodes
- bdrv_append() should in theory require the node to be drained; in
practice most callers just lock the AioContext, which should at least
be enough to prevent concurrent I/O requests from accessing invalid
limits
So we can resolve the bug by making bdrv_refresh_limits() non-recursive.

Per the 82078 datasheet, if the end-of-track (EOT byte in
the FIFO) is more than the number of sectors per side, the
command is terminated unsuccessfully:
* 5.2.5 DATA TRANSFER TERMINATION
The 82078 supports terminal count explicitly through
the TC pin and implicitly through the underrun/over-
run and end-of-track (EOT) functions. For full sector
transfers, the EOT parameter can define the last
sector to be transferred in a single or multisector
transfer. If the last sector to be transferred is a par-
tial sector, the host can stop transferring the data in
mid-sector, and the 82078 will continue to complete
the sector as if a hardware TC was received. The
only difference between these implicit functions and
TC is that they return "abnormal termination" result
status. Such status indications can be ignored if they
were expected.
* 6.1.3 READ TRACK
This command terminates when the EOT specified
number of sectors have been read. If the 82078
does not find an I D Address Mark on the diskette
after the second· occurrence of a pulse on the
INDX# pin, then it sets the IC code in Status Regis-
ter 0 to "01" (Abnormal termination), sets the MA bit
in Status Register 1 to "1", and terminates the com-
mand.
* 6.1.6 VERIFY
Refer to Table 6-6 and Table 6-7 for information
concerning the values of MT and EC versus SC and
EOT value.
* Table 6·6. Result Phase Table
* Table 6-7. Verify Command Result Phase Table
Fix by aborting the transfer when EOT > # Sectors Per Side.

RH-Commit: [2/2] f838a57f74487eb394794de00006d5d2b9e84344
kvm_put_sregs2() fails to reset 'locked' CR4/CR0 bits upon vCPU reset when
it is in VMX root operation. Do kvm_put_msr_feature_control() before
kvm_put_sregs2() to (possibly) kick vCPU out of VMX root operation. It also
seems logical to do kvm_put_msr_feature_control() before
kvm_put_nested_state() and not after it, especially when 'real' nested
state is set.

be stale after an incoming migration, kvm_arch_put_registers() may
end up failing or putting vCPU in a weird state.

RH-Commit: [1/1] 1e702e735ff63f2b8b69c20cac1b309dd085cd62

When we still have an AIOCB registered for DMA operations, we try to
settle the respective operation by draining the BlockBackend associated
with the IDE device.
However, this assumes that every DMA operation is associated with an
increment of the BlockBackend’s in-flight counter (e.g. through some
ongoing I/O operation), so that draining the BB until its in-flight
counter reaches 0 will settle all DMA operations. That is not the case:
For TRIM, the guest can issue a zero-length operation that will not
result in any I/O operation forwarded to the BlockBackend, and also not
increment the in-flight counter in any other way. In such a case,
blk_drain() will be a no-op if no other operations are in flight.
It is clear that if blk_drain() is a no-op, the value of
s->bus->dma->aiocb will not change between checking it in the `if`
condition and asserting that it is NULL after blk_drain().
The particular problem is that ide_issue_trim() creates a BH
(ide_trim_bh_cb()) to settle the TRIM request: iocb->common.cb() is
ide_dma_cb(), which will either create a new request, or find the
transfer to be done and call ide_set_inactive(), which clears
s->bus->dma->aiocb. Therefore, the blk_drain() must wait for
ide_trim_bh_cb() to run, which currently it will not always do.
To fix this issue, we increment the BlockBackend's in-flight counter
when the TRIM operation begins (in ide_issue_trim(), when the
ide_trim_bh_cb() BH is created) and decrement it when ide_trim_bh_cb()
is done.

Subject: [PATCH 3/5] iotests: Test blockdev-reopen with iothreads and
throttling
RH-Author: Kevin Wolf <kwolf@redhat.com>
RH-MergeRequest: 142: block: Lock AioContext for drain_end in blockdev-reopen
RH-Commit: [2/2] 91d365864c391ca7db7db13260913fb61987b833
RH-Bugzilla: 2067118
RH-Acked-by: Emanuele Giuseppe Esposito <eesposit@redhat.com>

RH-Acked-by: Hanna Reitz <hreitz@redhat.com>
The 'throttle' block driver implements .bdrv_co_drain_end, so
blockdev-reopen will have to wait for it to complete in the polling
loop at the end of qmp_blockdev_reopen(). This makes AIO_WAIT_WHILE()
release the AioContext lock, which causes a crash if the lock hasn't
correctly been taken.

RH-Author: Hanna Reitz <hreitz@redhat.com>
RH-MergeRequest: 189: block: Make bdrv_refresh_limits() non-recursive
RH-Commit: [3/3] b9dffe09bef6cf9b2f0aad69b327ea1df92e847a
RH-Bugzilla: 2072932
RH-Acked-by: Eric Blake <eblake@redhat.com>

RH-Acked-by: Kevin Wolf <kwolf@redhat.com>
Test the following scenario:
1. Some block node (null-co) attached to a user (here: NBD server) that
performs I/O and keeps the node in an I/O thread
2. Repeatedly run blockdev-add/blockdev-del to add/remove an overlay
to/from that node
Each blockdev-add triggers bdrv_refresh_limits(), and because
blockdev-add runs in the main thread, it does not stop the I/O requests.
I/O can thus happen while the limits are refreshed, and when such a
request sees a temporarily invalid block limit (e.g. alignment is 0),
this may easily crash qemu (or the storage daemon in this case).
The block layer needs to ensure that I/O requests to a node are paused
while that node's BlockLimits are refreshed.

Add a helper to cleanup the transport listener.
When do it, we should also null-ify the cleanup hook and the data, then it's
even safe to call it multiple times.
Move the socket_address_list cleanup altogether, because that's a mirror of the
listener channels and only for the purpose of query-migrate. Hence when
someone wants to cleanup the listener transport, it should also want to cleanup
the socket list too, always.
No functional change intended.

Previously migration didn't have an easy way to cleanup the listening
transport, migrate recovery only allows to execute once. That's done with a
trick flag in postcopy_recover_triggered.
Now the facility is already there.
Drop postcopy_recover_triggered and instead allows a new migrate-recover to
release the previous listener transport.

physical block size
RH-Author: Thomas Huth <thuth@redhat.com>
RH-MergeRequest: 207: pc-bios/s390-ccw: Fix booting with logical block size < physical block size
RH-Commit: [1/1] ab22832592e0a48277bf7aca1b941a1be79aeab6
RH-Bugzilla: 2112296
RH-Acked-by: Cornelia Huck <cohuck@redhat.com>
RH-Acked-by: David Hildenbrand <david@redhat.com>
RH-Acked-by: Claudio Imbrenda <None>
For accessing single blocks during boot, it's the logical block size that
matters. (Physical block sizes are rather interesting e.g. for creating
file systems with the correct alignment for speed reasons etc.).
So the s390-ccw bios has to use the logical block size for calculating
sector numbers during the boot phase, the "physical_block_exp" shift
value must not be taken into account. This change fixes the boot process
when the guest hast been installed on a disk where the logical block size
differs from the physical one, e.g. if the guest has been installed
like this:
qemu-system-s390x -nographic -accel kvm -m 2G \
-drive if=none,id=d1,file=fedora.iso,format=raw,media=cdrom \
-device virtio-scsi -device scsi-cd,drive=d1 \
-drive if=none,id=d2,file=test.qcow2,format=qcow2
-device virtio-blk,drive=d2,physical_block_size=4096,logical_block_size=512
Linux correctly uses the logical block size of 512 for the installation,
but the s390-ccw bios tries to boot from a disk with 4096 block size so
far, as long as this patch has not been applied yet (well, it used to work
by accident in the past due to the virtio_assume_scsi() hack that used to
enforce 512 byte sectors on all virtio-block disks, but that hack has been
well removed in commit 5447de2619050a0a4d to fix other scenarios).

pc-bios/s390-ccw: Split virtio-scsi code from virtio_blk_setup_device()
The next patch is going to add more virtio-block specific code to
virtio_blk_setup_device(), and if the virtio-scsi code is also in
there, this is more cumbersome. And the calling function virtio_setup()
in main.c looks at the device type already anyway, so it's more
logical to separate the virtio-scsi stuff into a new function in
virtio-scsi.c instead.

pc-bios/s390-ccw/bootmap: Improve the guessing logic in zipl_load_vblk()
The logic of trying an final ISO or ECKD boot on virtio-block devices is
very weird: Since the geometry hardly ever matches in virtio_disk_is_scsi(),
virtio_blk_setup_device() always sets a "guessed" disk geometry via
virtio_assume_scsi() (which is certainly also wrong in a lot of cases).
zipl_load_vblk() then sees that there's been a "virtio_guessed_disk_nature"
and tries to fix up the geometry again via virtio_assume_iso9660() before
always trying to do ipl_iso_el_torito(). That's a very brain-twisting
way of attempting to boot from ISO images, which won't work anymore after
the following patches that will clean up the virtio_assume_scsi() mess
(and thus get rid of the "virtio_guessed_disk_nature" here).
Let's try a better approach instead: ISO files always have a magic
string "CD001" at offset 0x8001 (see e.g. the ECMA-119 specification)
which we can use to decide whether we should try to boot in ISO 9660
mode (which we should also try if we see a sector size of 2048).
And if we were not able to boot in ISO mode here, the final boot attempt
before panicking is to boot in ECKD mode. Since this is our last boot
attempt anyway, simply always assume the ECKD geometry here (if the sector
size was not 4096 yet), so that we also do not depend on the guessed disk
geometry from virtio_blk_setup_device() here anymore.

pc-bios/s390-ccw/virtio: Beautify the code for reading virtqueue configuration
It looks nicer if we separate the run_ccw() from the IPL_assert()
statement, and the error message should talk about "virtio device"
instead of "block device", since this code is nowadays used for
non-block (i.e. network) devices, too.

pc-bios/s390-ccw/virtio: Read device config after feature negotiation
Feature negotiation should be done first, since some fields in the
config area can depend on the negotiated features and thus should
rather be read afterwards.
While we're at it, also adjust the error message here a little bit
(the code is nowadays used for non-block virtio devices, too).

the device. The s390-ccw bios skipped these steps so far and seems
like QEMU never cared. Anyway, it's better to follow the spec, so
let's set these bits now in the right spots, too.

pc-bios/s390-ccw/virtio-blkdev: Remove virtio_assume_scsi()
The virtio_assume_scsi() function is very questionable: First, it
is only called for virtio-blk, and not for virtio-scsi, so the naming
is already quite confusing. Second, it is called if we detected a
"invalid" IPL disk, trying to fix it by blindly setting a sector
size of 512. This of course won't work in most cases since disks
might have a different sector size for a reason.
Thus let's remove this strange function now. The calling code can
also be removed completely, since there is another spot in main.c
that does "IPL_assert(virtio_ipl_disk_is_valid(), ...)" to make
sure that we do not try to IPL from an invalid device.

pc-bios/s390-ccw/virtio-blkdev: Request the right feature bits
The virtio-blk code uses the block size and geometry fields in the
config area. According to the virtio-spec, these have to be negotiated
with the right feature bits during initialization, otherwise they
might not be available. QEMU is so far very forgiving and always
provides them, but we should not rely on this behavior, so let's
better request them properly via the VIRTIO_BLK_F_GEOMETRY and
VIRTIO_BLK_F_BLK_SIZE feature bits.

pc-bios/s390-ccw/virtio-blkdev: Simplify/fix virtio_ipl_disk_is_valid()
The s390-ccw bios fails to boot if the boot disk is a virtio-blk
disk with a sector size of 4096. For example:
dasdfmt -b 4096 -d cdl -y -p -M quick /dev/dasdX
fdasd -a /dev/dasdX
install a guest onto /dev/dasdX1 using virtio-blk
qemu-system-s390x -nographic -hda /dev/dasdX1
The bios then bails out with:
! Cannot read block 0 !
Looking at virtio_ipl_disk_is_valid() and especially the function
virtio_disk_is_scsi(), it does not really make sense that we expect
only such a limited disk geometry (like a block size of 512) for
our boot disks. Let's relax the check and allow everything that
remotely looks like a sane disk.

commit 2df59b73e0864f021f6179f32f7ed364f6d4f38d
Author: Nico Boehr <nrb@linux.ibm.com>
Date: Thu Dec 16 14:16:57 2021 +0100
s390x/css: fix PMCW invalid mask
Previously, we required bits 5, 6 and 7 to be zero (0x07 == 0b111). But,
as per the principles of operation, bit 5 is ignored in MSCH and bits 0,
1, 6 and 7 need to be zero.
As both PMCW_FLAGS_MASK_INVALID and ioinst_schib_valid() are only used
by ioinst_handle_msch(), adjust the mask accordingly.
Fixes: db1c8f53bfb1 ("s390: Channel I/O basic definitions.")

s390x/ipl: support extended kernel command line size
In the past s390 used a fixed command line length of 896 bytes. This has changed
with the Linux commit 5ecb2da660ab ("s390: support command lines longer than 896
bytes"). There is now a parm area indicating the maximum command line size. This
parm area has always been initialized to zero, so with older kernels this field
would read zero and we must then assume that only 896 bytes are available.

KVM support for AMX includes a new system attribute, KVM_X86_XCOMP_GUEST_SUPP.
Commit 19db68ca68 ("x86: Grant AMX permission for guest", 2022-03-15) however
did not fully consider the behavior on older kernels. First, it warns
too aggressively. Second, it invokes the KVM_GET_DEVICE_ATTR ioctl
unconditionally and then uses the "bitmask" variable, which remains
uninitialized if the ioctl fails. Third, kvm_ioctl returns -errno rather
than -1 on errors.
While at it, explain why the ioctl is needed and KVM_GET_SUPPORTED_CPUID
is not enough.

When user uses '-acpitable' to add SLIC table, some ACPI
tables (FADT) will change its 'Oem ID'/'Oem Table ID' fields to
match that of SLIC. Test makes sure thati QEMU handles
those fields correctly when SLIC table is added with
'-acpitable' option.

Previous patch [1] added explicit whitespace padding to OEM_ID/OEM_TABLE_ID

testcase ceased to test values that were shorter than max possible
length values.

The next commit will revert OEM fields whitespace padding to

Table ID for:

after reverting whitespace padding, it will be replaced with
'\0' which effectively will shorten OEM table ID to 6 and 2
