Subject: RE: [PATCH v2 00/25] Enable FRED with KVM VMX
Date: Mon, 15 Apr 2024 17:58:58 +0000 [thread overview]
Message-ID: <SA1PR11MB67345E7BB7842141DA2560F5A8092@SA1PR11MB6734.namprd11.prod.outlook.com> (raw)
In-Reply-To: <20240207172646.3981-1-xin3.li@intel.com>
> This patch set enables the Intel flexible return and event delivery

Obviously I will drop the 2 clean patches in the next iteration.
> Patch 3-15 add FRED support to VMX.
> Patch 16-21 add FRED support to nested VMX.
> Patch 22 exposes FRED and its baseline features to KVM guests.
> Patch 23-25 add FRED selftests.
Please help to review and comment on the FRED KVM/VMX patches.
Thanks!
