[PULL 01/54] acpi: add interface to build device specific AML

[Michael S. Tsirkin]

From: Igor Mammedov <imammedo@redhat.com>

There is already ISADeviceClass::build_aml() callback which
builds device specific AML blob for some ISA devices.
To extend the same idea to other devices, add TYPE_ACPI_DEV_AML_IF
Interface that will provide a more generic callback which
will be used not only for ISA but other devices. It will
allow get rid of some data-mining and ad-hoc AML building,
by asking device(s) to generate its own AML blob like it's
done for ISA devices.

[PULL 02/54] acpi: make isa_build_aml() support AcpiDevAmlIf interface

[Michael S. Tsirkin]

From: Igor Mammedov <imammedo@redhat.com>

To allow incremental conversion from ISADeviceClass::build_aml
to AcpiDevAmlIf, add support for the later without removing
the former. Once conversion is complete, another commit will
drop ISADeviceClass::build_aml related code.

[PULL 13/54] ipmi: acpi: use relative path to resource source

[Michael S. Tsirkin]

From: Igor Mammedov <imammedo@redhat.com>

smbus-ipmi AML description needs to specify a path to its parent
node in _CRS. The rest of IPMI inplementations (ISA based)
do not need path at all. Instead of passing through a full path
use relative path to point to smbus-ipmi's parent node, it will
let follow up patches to create IPMI device AML in a generic
way instead of current ad-hoc way. (i.e. AML will be generated
the same way it's done for other ISA device, and smbus will be
converted to generate AML for its slave devices the same way
as ISA)

expected AML change:
     Name (_CRS, ResourceTemplate ()  // _CRS: Current Resource Settings
     {
        I2cSerialBusV2 (0x0000, ControllerInitiated, 0x000186A0,

[PULL 15/54] acpi: ich9-smb: add support for AcpiDevAmlIf interface

[Michael S. Tsirkin]

From: Igor Mammedov <imammedo@redhat.com>

wire AcpiDevAmlIf interface to build ich9-smb and its slave
devices AML. It will be used by followup patches to switch
from creating AML in ad-hoc way to a more systematic one
that will scan present devices and ask them to provide
their AML code like it's done with ISA devices.

This patch is a partial conversion, as it only fetches
AML from slave devices attached to its I2C bus.

The conversion will be completed when PCI bus is
switched to use AcpiDevAmlIf and build_smb0() could be
dropped.

[PULL 16/54] acpi: ipmi: use AcpiDevAmlIf interface to build IPMI device descriptors

[Michael S. Tsirkin]

From: Igor Mammedov <imammedo@redhat.com>

convert ad-hoc way we use to generate AML for ISA/SMB IPMI devices
to a generic approach (i.e. make devices provide its own AML blobs
like it is done with other ISA devices (ex. KBD))

[PULL 17/54] q35: acpi: drop not needed PCMachineClass::do_not_add_smb_acpi

[Michael S. Tsirkin]

From: Igor Mammedov <imammedo@redhat.com>

by default we do not version ACPI AML as it's considered
a part of firmware. Drop do_not_add_smb_acpi that blocked
SMBUS AML description on 3.1 and older machine types without
providing justification.

[PULL 19/54] acpi: pc: isa bridge: use AcpiDevAmlIf interface to build ISA device descriptors

[Michael S. Tsirkin]

From: Igor Mammedov <imammedo@redhat.com>

replaces ad-hoc build_isa_devices_aml() with generic AcpiDevAmlIf
way to build bridge AML including all devices that are attached to
its ISA bus.

Later when PCI is converted to AcpiDevAmlIf, build_piix4_isa_bridge()
will also be dropped since PCI parts itself will take care of
building device prologue/epilogue AML for each enumerated PCI
device.

Expected AML change is contextual, where ISA devices are moved
from separately declared _SB.PCI0.ISA scope , directly under
Device(ISA) node.

[PULL 24/54] acpi: applesmc: use AcpiDevAmlIfClass:build_dev_aml to provide device's AML

[Michael S. Tsirkin]

From: Igor Mammedov <imammedo@redhat.com>

  .. and clean up not longer needed conditionals in DSTD build
code. applesmc AML will be fetched and included when ISA bridge
will build its own AML code (incl. attached devices).

Expected AML change:
the device under separate _SB.PCI0.ISA scope is moved directly
under Device(ISA) node.

[PULL 28/54] acpi: pvpanic-isa: use AcpiDevAmlIfClass:build_dev_aml to provide device's AML

[Michael S. Tsirkin]

From: Igor Mammedov <imammedo@redhat.com>

.. and clean up not longer needed conditionals in DSTD build code
pvpanic-isa AML will be fetched and included when ISA bridge will
build its own AML code (including attached devices).

Expected AML change:
   the device under separate _SB.PCI0.ISA scope is moved directly
   under Device(ISA) node.

From: Igor Mammedov <imammedo@redhat.com>

.. and clean up not longer needed conditionals in DSTD build code
tpm-tis AML will be fetched and included when ISA bridge will

Expected AML change:
    the device under separate _SB.PCI0.ISA scope is moved directly
    under Device(ISA) node.

[PULL 35/54] x86: acpi-build: do not include hw/isa/isa.h directly

[Michael S. Tsirkin]

From: Igor Mammedov <imammedo@redhat.com>

the last remaining dependency on ISA in acpi-build.c
is iapc_boot_arch_8042() which pulls in in isa.h
in its own header hw/input/i8042.h. Clean up
not longer needed direct inclusion of isa.h in
acpi-build.c

[PULL 36/54] hw/cxl: Make the CXL fixed memory window setup a machine parameter.

[Michael S. Tsirkin]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Paolo Bonzini requested this change to simplify the ongoing
effort to allow machine setup entirely via RPC.

Includes shortening the command line form cxl-fixed-memory-window
to cxl-fmw as the command lines are extremely long even with this
change.

The json change is needed to ensure that there is
a CXLFixedMemoryWindowOptionsList even though the actual
element in the json is never used. Similar to existing
SgxEpcProperties.

Update qemu-options.hx to reflect that this is now a -machine
parameter.  The bulk of -M / -machine parameters are documented
under machine, so use that in preference to M.

Update cxl-test and bios-tables-test to reflect new parameters.

[PULL 40/54] pci/pci_expander_bridge: For CXL HB delay the HB register memory region setup.

[Michael S. Tsirkin]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

As the CXLState will no long be accessible via MachineState
at time of PXB_CXL realization, come back later from the machine specific
code to fill in the missing memory region setup. Only at this stage
is it possible to check if cxl=on, so that check is moved to this
later point.

Note that for multiple host bridges, the allocation order of the
register spaces is changed. This will be reflected in ACPI CEDT.

Stubs are added to handle case of CONFIG_PXB=n for machines that
call these functions.

The bus walking logic is common to all machines so add a utility
function + stub to cxl-host*.

[PULL 41/54] tests/acpi: Update q35/CEDT.cxl for new memory addresses.

[Michael S. Tsirkin]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

The CEDT table includes addreses of host bridge registers.
There are allocated in a different order due to the previous
patch, so update to the table is needed.

[PULL 42/54] hw/cxl: Move the CXLState from MachineState to machine type specific state.

[Michael S. Tsirkin]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

This removes the last of the CXL code from the MachineState where it
is visible to all Machines to only those that support CXL (currently i386/pc)
As i386/pc always support CXL now, stop allocating the state independently.

Note the pxb register hookup code runs even if cxl=off in order to detect
pxb_cxl host bridges and fail to start if any are present as they won't
have the control registers available.

[PULL 43/54] hw/machine: Drop cxl_supported flag as no longer useful

[Michael S. Tsirkin]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

As all the CXL elements have moved to boards that support
CXL, there is no need to maintain a top level flag.

[PULL 44/54] pci: fix overflow in snprintf string formatting

[Michael S. Tsirkin]

From: Claudio Fontana <cfontana@suse.de>

the code in pcibus_get_fw_dev_path contained the potential for a
stack buffer overflow of 1 byte, potentially writing to the stack an
extra NUL byte.

This overflow could happen if the PCI slot is >= 0x10000000,
and the PCI function is >= 0x10000000, due to the size parameter
of snprintf being incorrectly calculated in the call:

    if (PCI_FUNC(d->devfn))
        snprintf(path + off, sizeof(path) + off, ",%x", PCI_FUNC(d->devfn));

since the off obtained from a previous call to snprintf is added
instead of subtracted from the total available size of the buffer.

Without the accurate size guard from snprintf, we end up writing in the
worst case:

name (32) + "@" (1) + SLOT (8) + "," (1) + FUNC (8) + term NUL (1) = 51 bytes

In order to provide something more robust, replace all of the code in
pcibus_get_fw_dev_path with a single call to g_strdup_printf,
so there is no need to rely on manual calculations.

Found by compiling QEMU with FORTIFY_SOURCE=3 as the error:

*** buffer overflow detected ***: terminated

Thread 1 "qemu-system-x86" received signal SIGABRT, Aborted.

[PULL 48/54] hw/acpi/viot: build array of PCI host bridges before generating VIOT ACPI table

[Michael S. Tsirkin]

From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

Perform the generation of the VIOT ACPI table in 2 separate passes: the first pass
enumerates all of the PCI host bridges and adds the min_bus and max_bus information
to an array.

Once this is done the VIOT table header is generated using the size of the array
to calculate the node count, which means it is no longer necessary to use a
sub-array to hold the PCI host bridge range information along with viommu_off.

Finally the PCI host bridge array is iterated again to add the required entries
to the final VIOT ACPI table.

[PULL 52/54] hw/virtio/vhost-user: don't use uninitialized variable

[Michael S. Tsirkin]

From: Changpeng Liu <changpeng.liu@intel.com>

Variable `vdev` in `struct vhost_dev` will not be ready
until start the device, so let's not use it for the error
output here.

[PULL 53/54] hw/vhost-user-scsi|blk: set `supports_config` flag correctly

[Michael S. Tsirkin]

From: Changpeng Liu <changpeng.liu@intel.com>

Currently vhost-user-scsi driver doesn't allow to change
the configuration space of virtio_scsi, while vhost-user-blk
support that, so here we set the flag in vhost-user-blk driver
and unset it in vhost-user-scsi.

[PULL 54/54] crypto: Introduce RSA algorithm

[Michael S. Tsirkin]

From: zhenwei pi <pizhenwei@bytedance.com>

There are two parts in this patch:
1, support akcipher service by cryptodev-builtin driver
2, virtio-crypto driver supports akcipher service

In principle, we should separate this into two patches, to avoid
compiling error, merge them into one.

Then virtio-crypto gets request from guest side, and forwards the
request to builtin driver to handle it.

Test with a guest linux:
1, The self-test framework of crypto layer works fine in guest kernel
2, Test with Linux guest(with asym support), the following script
test(note that pkey_XXX is supported only in a newer version of keyutils):
  - both public key & private key
  - create/close session
  - encrypt/decrypt/sign/verify basic driver operation
  - also test with kernel crypto layer(pkey add/query)

All the cases work fine.

Run script in guest:
rm -rf *.der *.pem *.pfx
modprobe pkcs8_key_parser # if CONFIG_PKCS8_PRIVATE_KEY_PARSER=m
rm -rf /tmp/data
dd if=/dev/random of=/tmp/data count=1 bs=20

openssl req -nodes -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -subj "/C=CN/ST=BJ/L=HD/O=qemu/OU=dev/CN=qemu/emailAddress=qemu@qemu.org"
openssl pkcs8 -in key.pem -topk8 -nocrypt -outform DER -out key.der
openssl x509 -in cert.pem -inform PEM -outform DER -out cert.der

PRIV_KEY_ID=`cat key.der | keyctl padd asymmetric test_priv_key @s`
echo "priv key id = "$PRIV_KEY_ID
PUB_KEY_ID=`cat cert.der | keyctl padd asymmetric test_pub_key @s`
echo "pub key id = "$PUB_KEY_ID

keyctl pkey_query $PRIV_KEY_ID 0
keyctl pkey_query $PUB_KEY_ID 0

echo "Enc with priv key..."
keyctl pkey_encrypt $PRIV_KEY_ID 0 /tmp/data enc=pkcs1 >/tmp/enc.priv

I checked this building log, and noticed that clang-13 reports this 
error. I tested this by clang-11(from Debian10). Sadly, clang-11 did not 
report this.

I'll fix&test this patch by clang-13, then send this patch again.

Thanks!

Hi. On my macos machine (an x86 one), 'make check' output for
the bios-tables-test for both i386 and x86-64 guests now includes
a warning message:

qemu-system-i386: -device isa-applesmc: warning: Using AppleSMC with invalid key

I have not bisected but I rather suspect that this is the result of
the applesmc test changes in this pullreq.

Like warning says, test case doesn't have SMC key after which
QEMU uses some made up default.

It can't suppressed with 'qtest_enabled()' since QEMU in test
doesn't use qtest as accelerator.

I'm more inclined to removing warning.

yes:

    if (!s->osk || (strlen(s->osk) != 64)) {
        warn_report("Using AppleSMC with invalid key");
        s->osk = default_osk;
    }

I would say the incorrect length is right in producing the
warning, but the !s->osk case shouldn't warn.

Alex what do you think?

Hi,
while trying to reproduce another issue, I ended up with a Windows 10
guest that would boot with QEMU 7.0, but get stuck after the Windows
logo/spinning circles with QEMU 7.1 (also with 8.0.0-rc1). Machine type
is pc-i440fx-6.2[0]. Bisecting led to this commit.

It only happens the first time the VM is booted, killing the process and
re-trying always worked afterwards. So it's not a big deal and might
just be some ACPI-related Windows quirk. But I thought I should ask here
to be sure.

For bisecting, I restored the disk state after each attempt. While
getting stuck sometimes took 3-4 attempts, I tested about 10 times until
I declared a commit good, and re-tested the commit before this one 15
times, so I'm pretty sure this is the one where the issue started appearing.

So, anything that could potentially be wrong with the commit or is this
most likely just some Windows quirk/bug we can't do much about?

If you need more information, please let me know!

Best Regards,
Fiona

Please describe in more detail your setup/steps where it reproduces
(incl. Windows version/build, used QEMU CLI) so I could try to reproduce it locally.

(in past there were issues with German version that some where
experience but not reproducible on my side, that resolved with
upgrading to newer QEMU (if I recall correctly issue was opened
on QEMU's gitlab tracker))

Windows 10 Education
Version 1809
Build 17763.1

It's not the German ISO, I used default settings (except location
Austria and German keymap) and I don't think I did anything other than
shutdown after the install was over.

The command line is below. I did use our patched QEMU builds when I got
into the situation, but I don't think they touch anything ACPI-related
and bisecting was done without our patches on top.

I tried to reproduce the situation again from scratch today, but wasn't
able to. I do still have the problematic disk (snapshot) where the issue
occurs as an LVM-Thin volume. If you'd like to have access to that,
please send me a direct mail and we can discuss the details there.

I couldn't reproduce the issue on my host either.
If you still have access to 'broken' disk image, you can try to enable
kernel debug mode in guest and try to attach with debugger to it to see
where it is stuck.

quick instructions how to do it:

or read more extensive MS docs on topic.

Hmm, I guess I won't be able to enable kernel debug mode without losing
the problematic state of the image. The VM only gets stuck during the
first boot attempt.

Still, I wanted to give it a shot in the hope I can trigger it again
when shutting down with QEMU 6.2.0 and booting with QEMU 7.1.0. I made a
copy of the VM intending to use it as the debug host, but didn't get the
COM port to show up in the guest with
-serial unix:/tmp/com1,server,nowait
I checked in the Device Manager with "Show hidden devices" enabled.

Anyway, when starting the original problematic VM again, it now also got
stuck (visually, in the same place) with QEMU 6.2.0! But only until I
rebooted my host, which made it working with QEMU 6.2.0 again. So I'd
say this commit has nothing to do with the issue after all, just made it
more likely to trigger for me. And also seems less likely to be a QEMU
issue now :)

Fiona

[Mike Maslenkin]

Sorry for the noise, but just curious, how did you shutdown Windows?
Did you use 'shutdown /s' or just press power button?
Could it be that Windows was actually hibernated.
So, when you try to boot it on the new (old) QEMU version with changed
PCI topology, this could make it upset.
I observed similar behaviour in case of Windows for ARM, but there was
true GSOD afterwards.
When windows is starting again its hibernated state dropped and all goes fine.

Mike

I think I either pressed the shutdown button in our UI, which sends
system_powerdown via QMP or via "Shut down" in the Windows start menu.
Hibernation is surely something I need to consider (next time), so thank
you for the hint, but if it were that, I'd be surprised at why it got
stuck even with QEMU 6.2.0 today.

If I try "shutdown /h" explicitly, I get "The request is not
supported.(50)".

Fiona

Re: [PULL 19/54] acpi: pc: isa bridge: use AcpiDevAmlIf interface to build ISA device descriptors

Hibernate is disabled by default, that is why "shutdown /h" fails.
It can be enabled by 'powercfg.exe /h /size 100; powercfg.exe /h on'

anyway, my hypotheses can be checked easily: just run the VM with
changed RAM size (±1). This should have to drop hibernate state.

BTW I couldn't reproduce problem as well.

You got it! The VM boots when I change the RAM size. I now enabled
hibernation and tried to reproduce the issue with "shutdown /h", but
couldn't. And not sure how the VM ended up hibernated when it was
disabled, maybe somehow as part of the installation/upgrades?
