Subject: [V2 PATCH 0/8] Execute hypercalls from guests according to cpu type
Date: Thu, 15 Sep 2022 00:04:40 +0000 [thread overview]
Message-ID: <20220915000448.1674802-1-vannapurve@google.com> (raw)
This series is posted in context of the discussion at:
https://lore.kernel.org/lkml/Ywa9T+jKUpaHLu%2Fl@google.com/
Changes in v2:
* Addressed comments from Andrew and David
* Common function with constructor attribute used to setup initial state
* Changes are split in more logical granules as per feedback
Major changes:
1) Move common startup logic to a single function in kvm_util.c
2) Introduce following APIs:
kvm_selftest_arch_init: to perform arch specific common startup.
kvm_arch_post_vm_elf_load: to update the guest memory state to convey
common information to guests.
3) For x86, capture cpu type at startup and pass on the cpu type to
guest after guest elf is loaded.
4) Execute hypercall instruction from within guest VMs according to the
cpu type. This will help prevent an extra kvm exit during hypercall
execution.
