tests: acpi: allow to override default accelerator
By default test cases were run with 'kvm:tcg' accelerators to speed up
tests execution. While it works for x86, were change of accelerator
doesn't affect ACPI tables, the approach doesn't works for ARM usecase
though.
In arm/virt case, KVM mode requires using 'host' cpu model, which
isn't available in TCG mode. That could be worked around with 'max'
cpu model, which works both for KVM and TCG. However in KVM mode it
is necessary to specify matching GIC version, which also could use
'max' value to automatically pick GIC version suitable for host's CPU.
Depending on host cpu type, different GIC versions would be used,
which in turn leads to different ACPI tables (APIC) generated.
As result while comparing with reference blobs, test would fail if
host's GIC version won't match the version on the host where
reference blobs where generated.
Let's keep testing simple for now and allow ARM tests run in TCG only
mode. To do so introduce 'accel' parameter in test configuration, so
test case could override default "kvm:tcg" with accelerator of choice.

set auto_finalize=false so the job will remain in the block graph as
long as we need it. This allows us to drop the rate limiting, too,

The only problem with this is that there is a single place that yields a
different error message depending on whether the stream job is still
copying data (so COR is enabled) or not (COR has been disabled, but the
job still has the WRITE_UNCHANGED permission on the target node). We
can easily address that by expecting either error message.

active commit job, because It never completes without an explicit

qemu-img: block/io.c:2093: bdrv_co_block_status: Assertion `*pnum &&
QEMU_IS_ALIGNED(*pnum, align) && align > offset - aligned_offset'

This is because bdrv_co_block_status() checks that the result returned
by the driver's implementation is aligned to the request_alignment, but
file-posix can fail to do so, which is actually mentioned in a comment
there: "[...] possibly including a partial sector at EOF".
Fix this by rounding up those partial sectors.
There are two possible alternative fixes:
(1) We could refuse to open unaligned image files with O_DIRECT
altogether. That sounds reasonable until you realize that qcow2
does necessarily not fill up its metadata clusters, and that nobody
runs qemu-img create with O_DIRECT. Therefore, unpreallocated qcow2
files usually have an unaligned image tail.
(2) bdrv_co_block_status() could ignore unaligned tails. It actually
throws away everything past the EOF already, so that sounds
reasonable.
Unfortunately, the block layer knows file lengths only with a
granularity of BDRV_SECTOR_SIZE, so bdrv_co_block_status() usually
would have to guess whether its file length information is inexact
or whether the driver is broken.
Fixing what raw_co_block_status() returns is the safest thing to do.
There seems to be no other block driver that sets request_alignment and
does not make sure that it always returns aligned values.

qmp_cont in RUN_STATE_FINISH_MIGRATE may lead to moving vm to
RUN_STATE_RUNNING, before actual migration finish. So, when migration
thread will try to go to RUN_STATE_POSTMIGRATE, assuming transition
RUN_STATE_FINISH_MIGRATE->RUN_STATE_POSTMIGRATE, it will crash, as
current state is RUN_STATE_RUNNING, and transition
RUN_STATE_RUNNING->RUN_STATE_POSTMIGRATE is forbidden.

block: Use BDRV_REQUEST_MAX_BYTES instead of BDRV_REQUEST_MAX_SECTORS
There are a few places in which we turn a number of bytes into sectors
in order to compare the result against BDRV_REQUEST_MAX_SECTORS
instead of using BDRV_REQUEST_MAX_BYTES directly.

qcow2: Define and use QCOW2_COMPRESSED_SECTOR_SIZE
When an L2 table entry points to a compressed cluster the space used
by the data is specified in 512-byte sectors. This size is independent
from BDRV_SECTOR_SIZE and is specific to the qcow2 file format.
The QCOW2_COMPRESSED_SECTOR_SIZE constant defined in this patch makes
this explicit.

block/file-posix: Truncate in xfs_write_zeroes()
XFS_IOC_ZERO_RANGE does not increase the file length:
$ touch foo
$ xfs_io -c 'zero 0 65536' foo
$ stat -c "size=%s, blocks=%b" foo
size=0, blocks=128
We do want writes beyond the EOF to automatically increase the file
length, however. This is evidenced by the fact that iotest 061 is
broken on XFS since qcow2's check implementation checks for blocks
beyond the EOF.

virtfs: Fix documentation of -fsdev and -virtfs
This fixes several things:

- add documentation and usage of the synth fsdriver
- add "throttling.*" description to -fsdev local
- add some missing periods
- add proper reference to the virtfs-proxy-helper(1) manual page
- document that the virtio device may be either virtio-9p-pci, virtio-9p-ccw

vl: Deprecate -virtfs_synth
The synth fsdriver never got used for anything else but the QTest
testcase for VirtIO 9P. And even there, QTest uses -fsdev synth and
-device virtio-9p-... directly.

fsdev: Error out when unsupported option is passed
Each fsdriver only supports a subset of the options that can be passed
to -fsdev. Unsupported options are simply ignored. This could cause the
user to erroneously think QEMU has a bug.
Enforce strict checking of supported options for all fsdrivers. This
shouldn't impact libvirt, since it doesn't know about the synth and
proxy fsdrivers.
Greg Kurz [Fri, 17 May 2019 15:34:48 +0000 (17:34 +0200)]
fsdev: Move some types definition to qemu-fsdev.c
It would make sense for these types to be defined in a header file if
we had an API for fsdrivers to register themselves. In practice, we
only have three of them and it is very unlikely we add new ones since
the future of file sharing between host and guest is the upcoming
virtio-fs.
Move the types to qemu-fsdev.c instead since they are only used there.
