Hi, Will, Marc,
Is there any further comment on the v3 series I post previously?
None, I was planning to queue them for 5.12 over the weekend.
If they are not fine to you, then I think maybe we should just turn

Randy found that with the following Kconfig settings we have duplicate

The ACRN Hypervisor builds an I/O request when a trapped I/O access
happens in User VM. Then, ACRN Hypervisor issues an upcall by sending
a notification interrupt to the Service VM. HSM in the Service VM needs
to hook the notification interrupt to handle I/O requests.

ACRN Hypervisor reports hypervisor features via CPUID leaf 0x4001
which is similar to KVM. A VM can check if it's the privileged VM using
the feature bits. The Service VM is the only privileged VM by design.

We will start building overlays for platforms soon in the kernel and
would need fdtoverlay going forward. Lets start building it.
The fdtoverlay program applies (or merges) one or more overlay dtb
blobs to a base dtb blob. The kernel build system would later use
fdtoverlay to generate the overlaid

What is the context switch buffer?
I think you mean simply the xstate per-task buffer which is switched on
context switches...
