[PATCH 0/4] KVM: x86: Advertise new instruction CPUIDs for Intel Diamond Rapids

Posted by Zhao Liu 1 week, 4 days ago

Hi,

This series advertises new instruction CPUIDs to userspace, which are
supported by Intel Diamond Rapids platform.

I've attached the spec link for each (family of) instruction in each
patch. Since the instructions included in this series don't require
additional enabling work, pass them through to guests directly.

This series is based on the master branch at the commit 23cb64fb7625
("Merge tag 'soc-fixes-6.18-3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc").

Thanks for your review!

Best Regards,
Zhao
