Hello,
kernel test robot noticed "kselftests.kvm.hyperv_evmcs.fail" on:
commit: 7fecb27e8d353adda91989eb01b3ae200b846a42 ("KVM: selftests: Always assert that vmwrite() succeeds") https://github.com/sean-jc/linux x86/evmcs_vmptrldst
in testcase: kselftests
version: kselftests-x86_64-f5098b6bae76-1_20260727
with following parameters:
group: kvm
config: x86_64-rhel-9.4-kselftests
compiler: gcc-14
test machine: 16 threads Intel(R) Core(TM) i7-13620H (Raptor Lake) with 32G memory
If you fix the issue in a separate patch/commit (i.e. not just a new version of the same patch/commit), kindly add following tags

I managed to *repeatedly* not update the repository I was using to build selftests.
Thank you friendly kernel test robot for saving me from major embarassment!

Ok, this is too funny not to tell someone, even if that someone ends up being a
bot.
I thought for sure I messed up the encoding, i.e. that the "vmwrite[0x0]" in the
report was either wrong, or or the encoding was getting clobbered along the way.
Nope, it just so happens that VIRTUAL_PROCESSOR_ID is encoding '0', and the very
first thing done by prepare_vmcs() => init_vmcs_control_fields() is:
vmwrite(VIRTUAL_PROCESSOR_ID, 0);
The actual bug is stupid simple (and also hilarious/typical):

}
Just to double check that I didn't botch the formatting, I verified that this:
