Hi Salil,
Below patch resolves VM live migration CPU stall issues.

memset(cpu->kvm_init_features, 0,
sizeof(cpu->kvm_init_features));
Root Cause:
It's too early to attach kvm_arm_vm_state_change handler in
kvm_arch_init_vcpu
since vcpus were not yet enabled at this stage
Because of this, QEMU is not fetching virtual time from KVM before
saving VM state
Also not able to restore virtual time back to KVM after restoring VM state
It is causing misconfiguration of vtimer offset and leading to CPU stall
issues.
Attaching kvm_arm_vm_state_change handler in virt_cpu_plug after
enabling each vCPU
makes more reasonable to me. Any suggestions are welcome here.
This helps to properly configure vtimer offset. And didn't see any
timing issues
_Regards_,
-Vishnu.

MPAM buglet..
by Jonathan Cameron
Given you mentioned rebasing MPAM :) One trivial bug that might still be hanging around.
When adding resources parsed from the MPAM ACPI table I think you are adding one byte
too much for IORESOURCE_MEM
https://git.kernel.org/pub/scm/linux/kernel/git/morse/linux.git/tree/driver…
should be a -1 similar to IORT handling.
https://elixir.bootlin.com/linux/latest/source/drivers/acpi/arm64/iort.c#L1…
As a side note, I'm emulating MPAM on QEMU so I can poke the corners of the code
beyond the real implementations we have access to and in a fashion I can talk about
more freely.
Other than the above, mostly seems to be working fine beyond a bug in the upstream
PPTT parsing code that doesn't affect what you have implemented so far.
There is an infinite loop / deadlock hiding somewhere though in one of the error paths
though that I haven't chased down yet. Maybe I'll be lucky and you've fixed it already :)
It's holiday season so might take a while to get the QEMU implementation finished / through
internal review - but I'll post any bugs I find in the meantime.

ARM64 vCPU Hotplug Kernel patches for discussion in community?
by Salil Mehta
Hi James,
Are you planning to push the next version (-V2) of vCPU Hotplug kernel changes to the community?
Is it possible to figure out any blockers on your end which are restricting you to move ahead.
I think kernel can move even when Qemu patches have not been pushed to community and
are only shared as repository. Though I shall been posting them soon.
It would be better if we can get kernel patches in discussion and then hope for their acceptance
as soon as possible. This is very important for acceptance of Qemu patches and to be frank
for anybody to take Qemu patches seriously even for discussion.
Many thanks
Salil.

[Question] Regarding the new _OSC capability to negotiate type of CPU Hotplug support (i.e. present/enable)
by Salil Mehta
Hi James,
Few questions related to new _OSC capabilities to negotiate the type of CPU hotplug(if any):
Q1: ACPI Standard Update: Do we have any Bugzilla-id for the change related to these new
_OSC capabilities for the type of CPU hotplug support (i.e. Enabled/Present cpu)?
Q2: Have you intentionally omitted below function in the _OSC related kernel change
shared in the repository [1]?
bool acpi_processor_hotplug_enabled_supported(void)
Q3: I am sure you would want to extend usage of these APIs in the acpi_processor.c as
well to decide what kind of hotplug (if any) is enabled? Is code related to _OSC changes
complete?
[1] https://gitlab.arm.com/linux-arm/linux-jm/-/commit/220b0d8b0261d7467c8705e6…

[Question - ARM CCA] Regarding vCPU Hotplug Support in ARM Realm world
by Salil Mehta
Hi James,
I recently got a chance to look into the ARM CCA specifications. And if I understood correctly then
in Realm world PSCI is managed by RMM but the Realm vCPUs are taken care by the host.
As per our recent changes we handle the SMC/HVC hyper call exits in user-space. If the VMs
are to run in Realm world and vCPU Hotplug needs to be supported then do we need
to consider any change there?
Thanks

[PATCH V3 1/1] qemu_v8: add support to run secondary OP-TEE
by shiju.jose＠huawei.com
From: Shiju Jose <shiju.jose(a)huawei.com>
Add changes to run a secondary OP-TEE at S-EL1 for SPMC_AT_EL=2,
where Hafnium is loaded at S-EL2.
Signed-off-by: Shiju Jose <shiju.jose(a)huawei.com>
Changes:
V2 -> V3
1. Changes w.r.t the relocatable OP-TEE support.
2. Remove building of secondary OP-TEE as the primary OP-TEE
binary use as the secondary OP-TEE as well.
V1 -> V2
1. Changed patch subject and patch description.
2. Fix for the comments from Jens Wiklander by adding separate
build flags and build path for the secondary OP-TEE.
