Commit ecebe53fe993 ("vfio: Avoid disabling and enabling vectors
repeatedly in VFIO migration") avoid inefficiently disabling and
enabling vectors repeatedly and let the unmasked vectors to be
enabled one by one.
But we want to batch multiple routes and defer the commit, and only
commit once out
'msix_vector_poll_notifier' should be reset to NULL in the error
path in msix_set_vector_notifiers().

It's unnecessary to test against the specific return value of
VFIO_DEVICE_SET_IRQS, since any positive return is an error
indicating the number of vectors we should retry with.

Hi guys,
In vfio migration resume phase, the cost would increase if the
vfio device has more unmasked vectors. We try to optimize it in
this series.
You can see the commit message in PATCH 9 for details.
Patch 1-5 are simple cleanups and fixup.
Patch 6-8 are the preparations for the

In migration resume phase, all unmasked msix vectors need to be
setup when load the VF state. However, the setup operation would
take longer if the VM has more VFs and each VF has more unmasked
vectors.
The hot spot is kvm_irqchip_commit_routes, it'll scan and update

'msix_function_masked' is synchronized with the device's config,
we can use it to replace the complex conditional statementis in

This patch adds support for PCIe Root Complex Event Collector
(RCEC) emulation. Further, if a RCiEP supports AER capability
then a mapping is created for that RCiEP in the RCEC's
endpoint association capability.

Hi All,
This is a first attempt to add PCIe Root Complex Event Collector emulation
support to Qemu. This patch is created on Qemu commit:88afdc92b6 and tested
using Qemu Risc V virt machine and the PCIe aer error injection module in the
Linux kernel(v 5.14).
Thanks,

CPUID leaf 0x14 subleaf 0x0 and 0x1 enumerate the resource and
capability of Intel PT.
Introduce FeatureWord FEAT_14_0_EBX, FEAT_14_1_EAX and FEAT_14_1_EBX,
and complete FEAT_14_0_ECX. Thus all the features of Intel PT can be
expanded when "-cpu host/max" and can be configured in named CPU model.
Initial Intel PT support was added by making it as fixed feature set as
ICX's capabilities, which allowed different CPU model with PT enabled
live migration on ICX host. However, it breaks the PT exposure/working
on SPR machine. Because SPR has less PT capabilities regrading
KVM only allows userspace to access legal number of MSR_IA32_RTIT_ADDRn,
which is enumrated by guest's CPUID(0x14,0x1):EAX[2:0], i.e.,
env->features[FEAT_14_1_EAX] & INTEL_PT_ADDR_RANGES_NUM_MASK

Is there a rule for when we should set is_jmp to DISAS_UPDATE_NOCHAIN,
when we should set it to
commit e37a5c7fa459 ("i386: Add Intel Processor Trace feature support")
added the support of Intel PT by making CPUID[14] of PT as fixed feature
set (from ICX) for any CPU model on any host.
This truly breaks the PT exposing on Intel SPR platform because SPR has
less supported bitmap

Although the doc comment says "Called within RCU critical section" the
address_space_read() function takes the RCU read lock itself. There is
no need for the caller to hold an RCU read lock.
