Subject: [PATCH] Revert "hw/s390x/s390-virtio-ccw: Remove the deprecated 4.1
machine type"
JIRA: https://issues.redhat.com/browse/RHEL-105900
Upstream status: downstream-only
This reverts commit 6ad3a47f15624176434490e895ac244375322607.
We still need the code for the old machine types since the -rhel7.6.0
machine type is based on these old upstream machine types.

selinux context 'system_u:object_r:virt_qemu_ga_log_t:s0', it

it's worth to mention that this is RHEL-only change for matching

Subject: [PATCH] Revert "hw/s390x/s390-virtio-ccw: Remove the deprecated 3.1
machine type"
This reverts commit 3b912daea079445aad40d8e189c40597b229cf10.
JIRA: https://issues.redhat.com/browse/RHEL-105900
Upstream status: downstream-only
We still need the code for the old machine types since the -rhel7.6.0
machine type is based on these old upstream machine types.

Subject: [PATCH] redhat: Fix -rhel7.6.0 machine type
JIRA: https://issues.redhat.com/browse/RHEL-105900
During the rebase to QEMU 10.1, we lost the S390_FEAT_LIST_QEMU_V3_1
setting for the -rhel7.6.0 machine type. Now that the upstream
patches that removed this setting got reverted, we can re-establish
it for the -rhel7.6.0 machine.

Subject: [PATCH] target/i386: add compatibility property for arch_capabilities
JIRA: https://issues.redhat.com/browse/RHEL-120257
Prior to v10.1, if requested by user, arch-capabilities is always on
despite the fact that CPUID advertises it to be off/unvailable.
This causes a migration issue for VMs that are run on a machine
without arch-capabilities and expect this feature to be present
on the destination host with QEMU 10.1.
Add a compatibility property to restore the legacy behavior for all
machines with version prior to 10.1.
To preserve the functionality (added by 10.1) of turning off
ARCH_CAPABILITIES where Windows does not like it, use directly
the guest CPU vendor: x86_cpu_get_supported_feature_word is not
KVM-specific and therefore should not necessarily use the host
CPUID.

Subject: [PATCH] target/i386: add compatibility property for pdcm feature
JIRA: https://issues.redhat.com/browse/RHEL-120257
The pdcm feature is supposed to be disabled when PMU is not
available. Up until v10.1, pdcm feature is enabled even when PMU
is off. This behavior has been fixed but this change breaks the
migration of VMs that are run with QEMU < 10.0 and expect the pdcm
feature to be enabled on the destination host.
This commit restores the legacy behavior for machines with version
prior to 10.1 to allow the migration from older QEMU to QEMU 10.1.

Subject: hw/arm/virt: Fix Manufacturer and Product Name in emulated SMBIOS
mode
Status: RHEL-only
In vm, when run 'dmidecode -t system', it outputs different Manufacturer
and Product Name on x86_64 and aarch64 system. For example:
For aarch64 vm:
Manufacturer: QEMU
Product Name: KVM Virtual Machine
For x86_64 vm:
Manufacturer: Red Hat
Product Name: KVM
Fixing this issue by changing Manufacturer to 'Red Hat' and Product
Name to 'KVM' on aarch64 platform. Thus the output is aligned on both
x86_64 and aarch64 platform.
To keep the compatability, this only apply for the RHEL9.6 machine
type. For RHEL9.4 machine type, it still keep the old Manufacturer and
Product Name.

RH-MergeRequest: 284: KVM: Dynamic sized kvm memslots array

RH-Commit: [4/7] 04d74707873b28a50b1e1bc08e4788c79455518c (peterx/qemu-kvm)
Zhiyi reported an infinite loop issue in VFIO use case. The cause of that
was a separate discussion, however during that I found a regression of
dirty sync slowness when profiling.
Each KVMMemoryListerner maintains an array of kvm memslots. Currently it's
statically allocated to be the max supported by the kernel. However after
Linux commit 4fc096a99e ("KVM: Raise the maximum number of user memslots"),
the max supported memslots reported now grows to some number large enough
so that it may not be wise to always statically allocate with the max
reported.
What's worse, QEMU kvm code still walks all the allocated memslots entries
to do any form of lookups. It can drastically slow down all memslot
operations because each of such loop can run over 32K times on the new
kernels.
Fix this issue by making the memslots to be allocated dynamically.
Here the initial size was set to 16 because it should cover the basic VM
usages, so that the hope is the majority VM use case may not even need to
grow at all (e.g. if one starts a VM with ./qemu-system-x86_64 by default
it'll consume 9 memslots), however not too large to waste memory.
There can also be even better way to address this, but so far this is the
simplest and should be already better even than before we grow the max
supported memslots. For example, in the case of above issue when VFIO was
attached on a 32GB system, there are only ~10 memslots used. So it could
be good enough as of now.
In the above VFIO context, measurement shows that the precopy dirty sync
shrinked from ~86ms to ~3ms after this patch applied. It should also apply
to any KVM enabled VM even without VFIO.
NOTE: we don't have a FIXES tag for this patch because there's no real
commit that regressed this in QEMU. Such behavior existed for a long time,
but only start to be a problem when the kernel reports very large
nr_slots_max value. However that's pretty common now (the kernel change
was merged in 2021) so we attached cc:stable because we'll want this change
to be backported to stable branches.

so to correctly name align with struct AMDVIState::variable type.
No functional change intended.

amd_iommu: Send notification when invalidate interrupt entry cache
In order to support AMD IOMMU interrupt remapping emulation with PCI
pass-through devices, QEMU needs to notify VFIO when guest IOMMU driver
updates and invalidate the guest interrupt remapping table (IRT), and
communicate information so that the host IOMMU driver can update
the shadowed interrupt remapping table in the host IOMMU.
Therefore, send notification when guest IOMMU emulates the IRT
invalidation commands.

Since the pauth and uso both should apply for the latest machine type,
move them to the arm_virt_compat_set() which applies the compat to all

RHEL9 kernels have pauth disabled while RHEL10 has it enabled,
since qemu will setup the VM/VCPU with pauth when KVM supports it
the guest visible ID registers will change when a RHEL9 qemu is
used on a RHEL10 kernel (e.g. in a container on a host with pauth
support).
Make sure that virt-rhel9* machine types in RHEL9 stay the same
independent of the kernel.

RH-Jira: RHEL-54296 RHEL-78397

RH-Commit: [14/22] e494fb6df6c363b6266e5fb7d09c31b3e7694f04 (kmwolf/centos-qemu-kvm)
The system emulator tries to automatically activate and inactivate block
nodes at the right point during migration. However, there are still
cases where it's necessary that the user can do this manually.
Images are only activated on the destination VM of a migration when the
VM is actually resumed. If the VM was paused, this doesn't happen
automatically. The user may want to perform some operation on a block
device (e.g. taking a snapshot or starting a block job) without also
resuming the VM yet. This is an example where a manual command is
necessary.
Another example is VM migration when the image files are opened by an
external qemu-storage-daemon instance on each side. In this case, the
process that needs to hand over the images isn't even part of the
migration and can't know when the migration completes. Management tools
need a way to explicitly inactivate images on the source and activate
them on the destination.
This adds a new blockdev-set-active QMP command that lets the user
change the status of individual nodes (this is necessary in
qemu-storage-daemon because it could be serving multiple VMs and only
one of them migrates at a time). For convenience, operating on all
devices (like QEMU does automatically during migration) is offered as an
option, too, and can be used in the context of single VM.

Subject: [PATCH 06/16] block: Add new bdrv_co_is_all_zeroes() function
RH-Author: Eric Blake <eblake@redhat.com>
RH-MergeRequest: 365: blockdev-mirror: More efficient handling of sparse mirrors
RH-Jira: RHEL-82906 RHEL-83015
RH-Acked-by: Stefan Hajnoczi <stefanha@redhat.com>

RH-Commit: [4/14] aabcba8323df698a72842f299e9242a5eee3aea6 (ebblake/centos-qemu-kvm)
There are some optimizations that require knowing if an image starts
out as reading all zeroes, such as making blockdev-mirror faster by
skipping the copying of source zeroes to the destination. The
existing bdrv_co_is_zero_fast() is a good building block for answering
this question, but it tends to give an answer of 0 for a file we just
created via QMP 'blockdev-create' or similar (such as 'qemu-img create
-f raw'). Why? Because file-posix.c insists on allocating a tiny
header to any file rather than leaving it 100% sparse, due to some
filesystems that are unable to answer alignment probes on a hole. But
teaching file-posix.c to read the tiny header doesn't scale - the
problem of a small header is also visible when libvirt sets up an NBD
client to a just-created file on a migration destination host.
So, we need a wrapper function that handles a bit more complexity in a
common manner for all block devices - when the BDS is mostly a hole,
but has a small non-hole header, it is still worth the time to read
that header and check if it reads as all zeroes before giving up and
returning a pessimistic answer.

RH-Commit: [13/22] 45b01b9c09d5f12715e4977cab6140d2cac90714 (kmwolf/centos-qemu-kvm)
In QEMU, nodes are automatically created inactive while expecting an
incoming migration (i.e. RUN_STATE_INMIGRATE). In qemu-storage-daemon,
the notion of runstates doesn't exist. It also wouldn't necessarily make
sense to introduce it because a single daemon can serve multiple VMs
that can be in different states.
Therefore, allow the user to explicitly open images as inactive with a
new option. The default is as before: Nodes are usually active, except
when created during RUN_STATE_INMIGRATE.

What we wanted to catch with the assertion is cases where the recursion
finds that a child was inactive before its parent. This should never
happen. But if the user tries to inactivate an image that is already
inactive, that's harmless and we don't want to fail the assertion.

RH-Commit: [17/22] f0fec0f51ed033038b565297a7217cbf61ab70f7 (kmwolf/centos-qemu-kvm)
So far the assumption has always been that if we try to inactivate a
node, it is already idle. This doesn't hold true any more if we allow
inactivating exported nodes because we can't know when new external
requests come in.
Drain the node around setting BDRV_O_INACTIVE so that requests can't
start operating on an active node and then in the middle it suddenly
becomes inactive. With this change, it's enough for exports to check
for new requests that they operate on an active node (or, like reads,
are allowed even on an inactive node).

RH-Commit: [1/14] 9de5245def80e9815ed306e4abce9caec56cef6f (ebblake/centos-qemu-kvm)
This patch is purely mechanical, changing bool want_zero into an
unsigned int for bitwise-or of flags. As of this patch, all
implementations are unchanged (the old want_zero==true is now
mode==BDRV_WANT_PRECISE which is a superset of BDRV_WANT_ZERO); but
the callers in io.c that used to pass want_zero==false are now
prepared for future driver changes that can now distinguish bewteen
BDRV_WANT_ZERO vs. BDRV_WANT_ALLOCATED. The next patch will actually
change the file-posix driver along those lines, now that we have
more-specific hints.
As for the background why this patch is useful: right now, the
file-posix driver recognizes that if allocation is being queried, the
entire image can be reported as allocated (there is no backing file to
refer to) - but this throws away information on whether the entire
image reads as zero (trivially true if lseek(SEEK_HOLE) at offset 0
returns -ENXIO, a bit more complicated to prove if the raw file was
created with 'qemu-img create' since we intentionally allocate a small
chunk of all-zero data to help with alignment probing). Later patches
will add a generic algorithm for seeing if an entire file reads as
zeroes.

RH-Commit: [12/22] e352c665f68a865859cc62fe1ed6e4044407b8e3 (kmwolf/centos-qemu-kvm)
In order for block_resize to fail gracefully on an inactive node instead
of crashing with an assertion failure in bdrv_co_write_req_prepare()
(called from bdrv_co_truncate()), we need to check for inactive nodes
also when they are attached as a root node and make sure that
BLK_PERM_RESIZE isn't among the permissions allowed for inactive nodes.
To this effect, don't enumerate the permissions that are incompatible
with inactive nodes any more, but allow only BLK_PERM_CONSISTENT_READ
for them.

RH-Commit: [9/22] 59b39138f0da734d497f3a58d458992abc348978 (kmwolf/centos-qemu-kvm)
Putting an active block node on top of an inactive one is strictly
speaking an invalid configuration and the next patch will turn it into a
hard error.
However, taking a snapshot while disk images are inactive after
completing migration has an important use case: After migrating to a
file, taking an external snapshot is what is needed to take a full VM
snapshot.
In order for this to keep working after the later patches, change
creating a snapshot such that it automatically inactivates an overlay
that is added on top of an already inactive node.

Some BDS drivers have a cap on how much block status they can supply
in one query (for example, NBD talking to an older server cannot
inspect more than 4G per query; and qcow2 tends to cap its answers
rather than cross a cluster boundary of an L1 table). Although the
existing callers of bdrv_co_is_zero_fast are not passing in that large
of a 'bytes' parameter, an upcoming caller wants to query the entire
image at once, and will thus benefit from being able to treat adjacent
zero regions in a coalesced manner, rather than claiming the region is
non-zero merely because pnum was truncated and didn't match the
incoming bytes.
While refactoring this into a loop, note that there is no need to
assign pnum prior to calling bdrv_co_common_block_status_above() (it
is guaranteed to be assigned deeper in the callstack).

RH-Commit: [15/22] 17405266afeddc47f73828816d0b8c1ab5ece462 (kmwolf/centos-qemu-kvm)
Device models have a relatively complex way to set up their block
backends, in which blk_attach_dev() sets blk->disable_perm = true.
We want to support inactive images in exports, too, so that
qemu-storage-daemon can be used with migration. Because they don't use
blk_attach_dev(), they need another way to set this flag. The most
convenient is to do this automatically when an inactive node is attached
to a BlockBackend that can be inactivated.

Add an option in BlockExportOptions to allow creating an export on an
inactive node without activating the node. This mode needs to be
explicitly supported by the export type (so that it doesn't perform any
operations that are forbidden for inactive nodes), so this patch alone
doesn't allow this option to be successfully used yet.

RH-Commit: [2/3] 0028fb11f18e16e2aba9506eabb2383c406d17b5 (stefanha/centos-stream-qemu-kvm)
When guests send misaligned discard requests, the block layer breaks
them up into a misaligned head, an aligned main body, and a misaligned
tail.
The file-posix block driver on Linux returns -EINVAL on misaligned
discard requests. This causes bdrv_co_pdiscard() to fail and guests
configured with werror=stop will pause.
Add a special case for misaligned head/tail requests. Simply continue
when EINVAL is encountered so that the aligned main body of the request
can be completed and the guest is not paused. This is the best we can do
when guest discard limits do not match the host discard limits.

RH-Commit: [4/30] b16fe5c9af4756e1856cd330df02a1a09d9f33ea (stefanha/centos-stream-qemu-kvm)
The 'fd_chr_read' method has a 4k byte array used for copying
data between the socket and device. Skip the automatic zero-init
of this array to eliminate the performance overhead in the I/O
hot path.
The 'buf' array will be fully initialized when reading data off
the network socket.

RH-Commit: [71/115] c876a59ee5bbfccea9837ac373a2e664354db3ae (bonzini/rhel-qemu-kvm)
QEMU calls kvm_arch_put_registers() when vcpu_dirty is true in
kvm_vcpu_exec(). However, for confidential guest, like TDX, putting
registers is disallowed due to guest state is protected.
Only set vcpu_dirty to true with guest state is not protected when
creating the vcpu.

+Intel Trusted Domain eXtension (TDX)
+====================================
+
+Intel Trusted Domain eXtensions (TDX) refers to an Intel technology that extends
+Virtual Machine Extensions (VMX) and Multi-Key Total Memory Encryption (MKTME)
+with a new kind of virtual machine guest called a Trust Domain (TD). A TD runs
+in a CPU mode that is designed to protect the confidentiality of its memory
+contents and its CPU state from any other software, including the hosting
+Virtual Machine Monitor (VMM), unless explicitly shared by the TD itself.
+
+Prerequisites
+-------------
+
+To run TD, the physical machine needs to have TDX module loaded and initialized
+while KVM hypervisor has TDX support and has TDX enabled. If those requirements
+are met, the ``KVM_CAP_VM_TYPES`` will report the support of ``KVM_X86_TDX_VM``.
+
+Trust Domain Virtual Firmware (TDVF)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Trust Domain Virtual Firmware (TDVF) is required to provide TD services to boot
+TD Guest OS. TDVF needs to be copied to guest private memory and measured before
+the TD boots.
+
+KVM vcpu ioctl ``KVM_TDX_INIT_MEM_REGION`` can be used to populate the TDVF
+content into its private memory.
+
+Since TDX doesn't support readonly memslot, TDVF cannot be mapped as pflash
+device and it actually works as RAM. "-bios" option is chosen to load TDVF.
+
+OVMF is the opensource firmware that implements the TDVF support. Thus the
+command line to specify and load TDVF is ``-bios OVMF.fd``
+
+Feature Configuration
+---------------------
+
+Unlike non-TDX VM, the CPU features (enumerated by CPU or MSR) of a TD are not
+under full control of VMM. VMM can only configure part of features of a TD on
+``KVM_TDX_INIT_VM`` command of VM scope ``MEMORY_ENCRYPT_OP`` ioctl.
+
+The configurable features have three types:
+
+- Attributes:
+ - PKS (bit 30) controls whether Supervisor Protection Keys is exposed to TD,
+ which determines related CPUID bit and CR4 bit;
+ - PERFMON (bit 63) controls whether PMU is exposed to TD.
+
+- XSAVE related features (XFAM):
+ XFAM is a 64b mask, which has the same format as XCR0 or IA32_XSS MSR. It
+ determines the set of extended features available for use by the guest TD.
+
+- CPUID features:
+ Only some bits of some CPUID leaves are directly configurable by VMM.
+
+What features can be configured is reported via TDX capabilities.
+
+TDX capabilities
+~~~~~~~~~~~~~~~~
+
+The VM scope ``MEMORY_ENCRYPT_OP`` ioctl provides command ``KVM_TDX_CAPABILITIES``
+to get the TDX capabilities from KVM. It returns a data structure of
+``struct kvm_tdx_capabilities``, which tells the supported configuration of
+attributes, XFAM and CPUIDs.
+
+TD attributes
+~~~~~~~~~~~~~
+
+QEMU supports configuring raw 64-bit TD attributes directly via "attributes"
+property of "tdx-guest" object. Note, it's users' responsibility to provide a
+valid value because some bits may not supported by current QEMU or KVM yet.
+
+QEMU also supports the configuration of individual attribute bits that are
+supported by it, via properties of "tdx-guest" object.
+E.g., "sept-ve-disable" (bit 28).
+
+MSR based features
+~~~~~~~~~~~~~~~~~~
+
+Current KVM doesn't support MSR based feature (e.g., MSR_IA32_ARCH_CAPABILITIES)
+configuration for TDX, and it's a future work to enable it in QEMU when KVM adds
+support of it.
+
+Feature check
+~~~~~~~~~~~~~
+
+QEMU checks if the final (CPU) features, determined by given cpu model and
+explicit feature adjustment of "+featureA/-featureB", can be supported or not.
+It can produce feature not supported warning like
+
+ "warning: host doesn't support requested feature: CPUID.07H:EBX.intel-pt [bit 25]"
+
+It can also produce warning like
+
+ "warning: TDX forcibly sets the feature: CPUID.80000007H:EDX.invtsc [bit 8]"
+
+if the fixed-1 feature is requested to be disabled explicitly. This is newly
+added to QEMU for TDX because TDX has fixed-1 features that are forcibly enabled
+by TDX module and VMM cannot disable them.
+
+Launching a TD (TDX VM)
+-----------------------
+
+To launch a TD, the necessary command line options are tdx-guest object and
+split kernel-irqchip, as below:
+
+.. parsed-literal::
+
+ |qemu_system_x86| \\
+ -accel kvm \\
+ -cpu host \\
+ -object tdx-guest,id=tdx0 \\
+ -machine ...,confidential-guest-support=tdx0 \\
+ -bios OVMF.fd \\
+
+Restrictions
+------------
+
+ - kernel-irqchip must be split;
+
+ This is set by default for TDX guest if kernel-irqchip is left on its default
+ 'auto' setting.
+
+ - No readonly support for private memory;
+
+ - No SMM support: SMM support requires manipulating the guest register states
+ which is not allowed;
+
+Debugging
+---------
+
+Bit 0 of TD attributes, is DEBUG bit, which decides if the TD runs in off-TD
+debug mode. When in off-TD debug mode, TD's VCPU state and private memory are
+accessible via given SEAMCALLs. This requires KVM to expose APIs to invoke those
+SEAMCALLs and corresonponding QEMU change.
+
+It's targeted as future work.
+
+TD attestation
+--------------
+
+In TD guest, the attestation process is used to verify the TDX guest
+trustworthiness to other entities before provisioning secrets to the guest.
+
+TD attestation is initiated first by calling TDG.MR.REPORT inside TD to get the
+REPORT. Then the REPORT data needs to be converted into a remotely verifiable
+Quote by SGX Quoting Enclave (QE).
+
+It's a future work in QEMU to add support of TD attestation since it lacks
+support in current KVM.
+
+Live Migration
+--------------
+
+Future work.

Subject: [PATCH 3/3] file-posix: Probe paths and retry SG_IO on potential path
errors
RH-Author: Kevin Wolf <kwolf@redhat.com>
RH-MergeRequest: 372: file-posix: Fix multipath failover with SCSI passthrough [9.7]
RH-Jira: RHEL-95408

RH-Commit: [2/2] 4312e9ec609e511afdfb6634e1d2370032d41543 (kmwolf/centos-qemu-kvm)
When scsi-block is used on a host multipath device, it runs into the
problem that the kernel dm-mpath doesn't know anything about SCSI or
SG_IO and therefore can't decide if a SG_IO request returned an error
and needs to be retried on a different path. Instead of getting working
failover, an error is returned to scsi-block and handled according to
the configured error policy. Obviously, this is not what users want,
they want working failover.
QEMU can parse the SG_IO result and determine whether this could have
been a path error, but just retrying the same request could just send it
to the same failing path again and result in the same error.
With a kernel that supports the DM_MPATH_PROBE_PATHS ioctl on dm-mpath
block devices (queued in the device mapper tree for Linux 6.16), we can
tell the kernel to probe all paths and tell us if any usable paths
remained. If so, we can now retry the SG_IO ioctl and expect it to be
sent to a working path.

RH-Commit: [2/14] 1f7b47ce5f5fb321aee41a16accf5bce3d1bfe95 (ebblake/centos-qemu-kvm)
Although the previous patch to change 'bool want_zero' into a bitmask
made no semantic change, it is now time to differentiate. When the
caller specifically wants to know what parts of the file read as zero,
we need to use lseek and actually reporting holes, rather than
short-circuiting and advertising full allocation.
This change will be utilized in later patches to let mirroring
optimize for the case when the destination already reads as zeroes.

JIRA: https://issues.redhat.com/browse/RHEL-68289
The semantic change has been introduced by commit 5becdc0ab0 ("hostmem:
simplify the code for merge and dump properties") even it clarifies that
no senmatic change has been introduced. After the commit, the merge
property can be applied even the corresponding memory region isn't
initialized yet. This leads to crash dump by the following command
lines.
# /home/gavin/sandbox/qemu.main/build/qemu-system-aarch64 \
-accel kvm -machine virt -cpu host \
-object memory-backend-ram,id=mem-memN0,size=4096M,merge=off
:
qemu-system-aarch64: ../system/memory.c:2419: memory_region_get_ram_ptr: \
Assertion `mr->ram_block' failed.
Fix it by applying the merge property only when the memory region is
initialized.

RH-MergeRequest: 298: [c9s] Fixes for the new s390x "boot order" feature

RH-Commit: [4/8] 7e3444e1fda776ca3b6de246b2dd696edf4980dd (thuth/qemu-kvm-cs9)
While adding the new flexible boot order feature on s390x recently,
we missed to add the "loadparm" property to the scsi-hd and scsi-cd
devices. This property is required on s390x to pass the information
to the boot loader about which kernel should be started or whether
the boot menu should be shown. But even more serious: The missing
property is now causing trouble with the corresponding libvirt patches
that assume that the "loadparm" property is either settable for all
bootable devices (when the "boot order" feature is implemented in
QEMU), or none (meaning the behaviour of older QEMUs that only allowed
one "loadparm" at the machine level). To fix this broken situation,
let's implement the "loadparm" property in for the SCSI devices, too.

RH-Commit: [3/5] e291cb45c32e0fab49b200c275553bbe76b97264 (eauger1/centos-qemu-kvm)
Currently the iommu may be reset before the devices
it protects. For example this happens with virtio-scsi-pci.
when system_reset is issued from qmp monitor: spurious
"virtio: zero sized buffers are not allowed" warnings can
be observed. This happens because outstanding DMA requests
are still happening while the SMMU gets reset.
This can also happen with VFIO devices. In that case
spurious DMA translation faults can be observed on host.
Make sure the SMMU is reset in the 'exit' phase after
all DMA capable devices have been reset during the 'enter'
or 'hold' phase.

The 'read_audio' & 'write_audio' methods have a 4k byte array used
for copying data between the audio backend and device. Skip the
automatic zero-init of these arrays to eliminate the performance
overhead in the I/O hot path.
The 'tmpbuf' array will be fully initialized when reading data from
the audio backend and/or device memory.

RH-Commit: [8/30] 6c454bcc2927e49896c62718287fb9e4b37b3bb9 (stefanha/centos-stream-qemu-kvm)
The 'cs_write_audio' method has a pair of byte arrays, one 4k in size
and one 8k, which are used in converting audio samples. Skip the
automatic zero-init of these arrays to eliminate the performance
overhead in the I/O hot path.
The 'tmpbuf' array will be fully initialized when reading a block of
data from the guest. The 'linbuf' array will be fully initialized
when converting the audio samples.

RH-Commit: [1/1] 4c7174da1dff8de3d7e2d88d84973eb69d6fc28a (sansshar/qemu-kvm-centos)
Brew build id: 5098441
In commit b88cfee90268cad we defined masks for the IBRD and FBRD
integer and fractional baud rate divider registers, to prevent the
guest from writing invalid values which could cause division-by-zero.
Unfortunately we got the mask values the wrong way around: the FBRD
register is six bits and the IBRD register is 16 bits, not
vice-versa.
You would only run into this bug if you programmed the UART to a baud
rate of less than 9600, because for 9600 baud and above the IBRD
value will fit into 6 bits, as per the table in
https://developer.arm.com/documentation/ddi0183/g/programmers-model/register-descriptions/fractional-baud-rate-register--uartfbrd
The only visible effects would be that the value read back from
the register by the guest would be truncated, and we would
print an incorrect baud rate in the debug logs.
