I see. I can drop this patch for now, but I suspect this
means this host always produced warning and possibly
that the tables are all wrong.
Could you send me the actual and expected files please?
Preferably both dsl and binary.

Sure, if you can give me commands to run to do that.

They are produced as part of the test.
So we have:
acpi-test: Warning! DSDT mismatch. Actual [asl:/tmp/asl-NKUU2Z.dsl,
aml:/tmp/aml-UERV2Z], Expected [asl:/tmp/asl-3ITW2Z.dsl,
aml:tests/data/acpi/q35/DSDT].
You would do something like:
tar cvzf tests.tgz /tmp/asl-NKUU2Z.dsl /tmp/aml-UERV2Z /tmp/asl-3ITW2Z.dsl tests/data/acpi/q35/DSDT
And then send the tarball.

Changelog:
- from v4:
* uefi support has been merged already, but only ARM part wasn't due to
test failing on ARM 32 bit host. It turned out that's aarch64 TCG issue
on 32-bit ARM host. Blacklist aarch64 test on 32 bit ARM host for now.
Series adds reference tables and a ACPI test case for arm/virt machine

this patch is ahead fo "tests: acpi: add simple arm/virt testcase"
to keep 'make check' working during bisection and not to pollute

adds simple arm/virt test case that starts guest with
bios-tables-test.aarch64.iso.qcow2 boot image which
initializes UefiTestSupport* structure in RAM once
guest is booted.

v6:
* Since aarch64 TCG is broken on 32 bit arm host,
blacklist it till it's fixed
* add aarch64 to rebuild script list
v4:
* force test to use TCG accelerator
v3:
* use firmware blobs directly from pc-bios directory
* use bios-tables-test.aarch64.iso.qcow2 as test boot image
* drop leftover qtest-uefi-images-aarch64 iMakefile rule from
previos version (Laszlo)
* add Makefile rule to include bios-tables-test into
check-qtest-aarch64 target
v2:
* specify in test_data where board's RAM starts and RAM size

I think you could also capture the following link here, in a comment:
# https://bugs.launchpad.net/qemu/+bug/1830872
> +ifneq ($(ARCH),arm)
Can we exclude all 32-bit host arches, not just ARM? The discussion in
LP#1830872 indicates aarch64-on-i386 can fail too (not this specific
guest payload FWIW, but the "tests/memory" test).
Other than that:

Michael,
could you fix it up on commit?
or we could merge v4
[PATCH v4 13/15] tests: acpi: add simple arm/virt testcase
which is the same modulo this blacklisting hunk, if
[RFC PATCH] cputlb: use uint64_t for interim values for unaligned load
fix is used as prerequisite.

I'd guess it's topic for a separate discussion (considering bios-tables-test
isn't affected it's probably not upto me to pull this trigger).

Expected table change is then handled like this:
1. add table to diff allowed list
2. change generating code (can be combined with 1)
3. maintainer runs a script to update expected +
blows away allowed diff list

'family' option is not part of type 2 table and if user tries to use it
as such QEMU will error out with an unknow option error.
Drop it from docs lest it confuse users.

'family' option is not part of type 2 table and if user tries to use it
as such QEMU will error out with an unknow option error.
Drop it from docs lest it confuse users.
Fixes: b155eb1d04 ("smbios: document cmdline options for smbios type 2-4, 17 structures")

This patch set tries to generalize MCFG table build process. Several patches
are already merged and these two are left for the following reasons:
* conflict with latest upstream
* ACPI_PCI dependency fix
* missed reserved[8] in MCFG
v4->v5:
* ACPI_PCI depends on both ACPI and PCI
* rebase on latest master, adjust arm Kconfig
* miss the reserved[8] of MCFG, add it back
* make sure bios-tables-test all OK

Now we have two identical build_mcfg functions.
Consolidate them in acpi/pci.c.
Signed-off-by: Wei Yang <richardw.yang@linux.intel.com>
v4:
* ACPI_PCI depends on both ACPI and PCI
* rebase on latest master, adjust arm Kconfig
v3:
* adjust changelog based on Igor's suggestion

build_append_foo() API doesn't need explicit endianness conversions
which eliminates a source of errors and it makes build_mcfg() look like
declarative definition of MCFG table in ACPI spec, which makes it easy
to review.

* [Qemu-devel] [PATCH v4 0/5] Simplify some not-really-necessary PCI bus callbacks
@ 2019-05-13 6:19 David Gibson
2019-05-13 6:19 ` [Qemu-devel] [PATCH v4 1/5] pcie: Remove redundant test in pcie_mmcfg_data_{read, write}() David Gibson
` (4 more replies)
0 siblings, 5 replies; 107+ messages in thread
From: David Gibson @ 2019-05-13 6:19 UTC (permalink / raw)
To: mst, qemu-devel; +Cc: aik, Mark Cave-Ayland, groug, qemu-ppc, David Gibson
c2077e2c "pci: Adjust PCI config limit based on bus topology"
introduced checking the availability of extended config space for
PCI-E devices which are in a bus topology that doesn't permit extended
config space access (e.g. under PCI-E to PCI then PCI to PCI-E
bridges).
This caused some problems for the spapr para-virtual PCI bus which
_does_ allow extended config space access, despite acting in most ways
like a vanilla PCI bus.
Greg Kurz made a fix for that which was merged as 1c685a90263 "pci:
Allow PCI bus subtypes to support extended config space accesses".
While that was an appropriate minimal fix for the 4.0 hard freeze, it
was kind of a hack longer term.
This series implements a simpler way of handling the extended config
space permission, which works for both the normal and weird-PAPR
cases. While we're there, we also make other small cleanups to the
PCI code.
Changes since v3:
* Remove a redundant call to pci_find_bus_nr() found during review
Changes since v2:
* Add some minor additional cleanups (patches 4 & 5)
* Minor whitespace tweak to patch 3
David Gibson (5):
pcie: Remove redundant test in pcie_mmcfg_data_{read,write}()
pci: Simplify pci_bus_is_root()
pcie: Simplify pci_adjust_config_limit()
pci: Make is_bridge a bool
pci: Fold pci_get_bus_devfn() into its sole caller

These functions have an explicit test for accesses above the device's
config size. But pci_host_config_{read,write}_common() which they're
about to call already have checks against the config space limit and
do the right thing. So, remove the redundant tests.

pci_bus_is_root() currently relies on a method in the PCIBusClass.
But it's always known if a PCI bus is a root bus when we create it, so
using a dynamic method is overkill.
This replaces it with an IS_ROOT bit in a new flags field, which is set on
root buses and otherwise clear. As a bonus this removes the special
is_root logic from pci_expander_bridge, since it already creates its bus
as a root bus.

Since c2077e2c "pci: Adjust PCI config limit based on bus topology",
pci_adjust_config_limit() has been used in the config space read and write
paths to only permit access to extended config space on buses which permit
it. Specifically it prevents access on devices below a vanilla-PCI bus via
some combination of bridges, even if both the host bridge and the device
itself are PCI-E.
It accomplishes this with a somewhat complex call up the chain of bridges
to see if any of them prohibit extended config space access. This is
overly complex, since we can always know if the bus will support such
access at the point it is constructed.
This patch simplifies the test by using a flag in the PCIBus instance
indicating whether extended configuration space is accessible. It is
false for vanilla PCI buses. For PCI-E buses, it is true for root
buses and equal to the parent bus's's capability otherwise.
For the special case of sPAPR's paravirtualized PCI root bus, which
acts mostly like vanilla PCI, but does allow extended config space
access, we override the default value of the flag from the host bridge
code.
This should cause no behavioural change.

From: Michael S. Tsirkin @ 2019-06-03 18:08 UTC (permalink / raw)
To: qemu-devel; +Cc: Peter Maydell, qemu-ppc, Greg Kurz, David Gibson
From: David Gibson <david@gibson.dropbear.id.au>
Since c2077e2c "pci: Adjust PCI config limit based on bus topology",
pci_adjust_config_limit() has been used in the config space read and write
paths to only permit access to extended config space on buses which permit
it. Specifically it prevents access on devices below a vanilla-PCI bus via
some combination of bridges, even if both the host bridge and the device
itself are PCI-E.
It accomplishes this with a somewhat complex call up the chain of bridges
to see if any of them prohibit extended config space access. This is
overly complex, since we can always know if the bus will support such
access at the point it is constructed.
This patch simplifies the test by using a flag in the PCIBus instance
indicating whether extended configuration space is accessible. It is
false for vanilla PCI buses. For PCI-E buses, it is true for root
buses and equal to the parent bus's's capability otherwise.
For the special case of sPAPR's paravirtualized PCI root bus, which
acts mostly like vanilla PCI, but does allow extended config space
access, we override the default value of the flag from the host bridge
code.
This should cause no behavioural change.

* [Qemu-devel] [PATCH v4 4/5] pci: Make is_bridge a bool
@ 2019-05-29 16:37 ` Michael S. Tsirkin

The is_bridge field in PCIDevice acts as a bool, but is declared as an int.
Declare it as a bool for clarity, and change everything that writes it to
use true/false instead of 0/1 to match.

The is_bridge field in PCIDevice acts as a bool, but is declared as an int.
Declare it as a bool for clarity, and change everything that writes it to
use true/false instead of 0/1 to match.

* [Qemu-devel] [PATCH v4 5/5] pci: Fold pci_get_bus_devfn() into its sole caller

The only remaining caller of pci_get_bus_devfn() is pci_nic_init_nofail(),
itself an old compatibility function. Fold the two together to avoid
re-using the stale interface.
While we're there replace the explicit fprintf()s with error_report().

The only remaining caller of pci_get_bus_devfn() is pci_nic_init_nofail(),
itself an old compatibility function. Fold the two together to avoid
re-using the stale interface.
While we're there replace the explicit fprintf()s with error_report().

Hi,
This patch series aims to add supprot to migrate a VM with a vhost-scsi device.
The 1st patch fixes a bug of mistakenly not stopping vhost-scsi backend when a
VM is stopped (As happens on migratino pre-copy completion).
The 2nd patch adds ability to save/load vhost-scsi device state in VMState.
The 3rd and final paqtch adds a flag to vhost-scsi which allows admin to specify
it's setup supports vhost-scsi migratino. For more detailed information on why
this is valid, see commit message of specific patch.
Regards,
-Liran

vhost-scsi doesn’t takes into account whether the VM is running or not in
order to decide if it should start/stop vhost backend.
This would lead to vhost backend still being active when VM's RunState
suddenly change to stopped.
An example of when this issue is encountered is when Live-Migration Pre-Copy
phase completes. As in this case, VM state will be changed to stopped (while
vhost backend is still active), which will result in
virtio_vmstate_change() -> virtio_set_status() -> vhost_scsi_set_status()
executed but vhost_scsi_set_status() will just return without stopping
vhost backend.
To handle this, change code to consider that vhost processing should be
stopped when VM is not running. Similar to how it is done in vhost-vsock
device at vhost_vsock_set_status().

In order to perform a valid migration of a vhost-scsi device,
the following requirements must be met:
(1) The virtio-scsi device state needs to be saved & loaded.
(2) The vhost backend must be stopped before virtio-scsi device state
is saved:
(2.1) Sync vhost backend state to virtio-scsi device state.
(2.2) No further I/O requests are made by vhost backend to target
SCSI device.
(2.3) No further guest memory access takes place after VM is stopped.
(3) Requests in-flight to target SCSI device are completed before
migration handover.
(4) Target SCSI device state needs to be saved & loaded into the
destination host target SCSI device.
Previous commit ("vhost-scsi: Add VMState descriptor")
add support to save & load the device state using VMState.
This meets requirement (1).
When VM is stopped by migration thread (On Pre-Copy complete), the
following code path is executed:
migration_completion() -> vm_stop_force_state() -> vm_stop() ->
do_vm_stop().
do_vm_stop() calls first pause_all_vcpus() which pause all guest
vCPUs and then call vm_state_notify().
In case of vhost-scsi device, this will lead to the following code path
to be executed:
vm_state_notify() -> virtio_vmstate_change() ->
virtio_set_status() -> vhost_scsi_set_status() -> vhost_scsi_stop().
vhost_scsi_stop() then calls vhost_scsi_clear_endpoint() and
vhost_scsi_common_stop().
vhost_scsi_clear_endpoint() sends VHOST_SCSI_CLEAR_ENDPOINT ioctl to
vhost backend which will reach kernel's vhost_scsi_clear_endpoint()
which process all pending I/O requests and wait for them to complete
(vhost_scsi_flush()). This meets requirement (3).
vhost_scsi_common_stop() will stop the vhost backend.
As part of this stop, dirty-bitmap is synced and vhost backend state is
synced with virtio-scsi device state. As at this point guest vCPUs are
already paused, this meets requirement (2).
At this point we are left with requirement (4) which is target SCSI
device specific and therefore cannot be done by QEMU. Which is the main
reason why vhost-scsi adds a migration blocker.
However, as this can be handled either by an external orchestrator or
by using shared-storage (i.e. iSCSI), there is no reason to limit the
orchestrator from being able to explictly specify it wish to enable
migration even when VM have a vhost-scsi device.
Considering all the above, this commit allows orchestrator to explictly
specify that it is responsbile for taking care of requirement (4) and
therefore vhost-scsi should not add a migration blocker.
