Subject: [PATCH v2 0/2] iommu/amd: Fix GAM IRTEs affinity and GALog restart
Date: Thu, 16 Mar 2023 20:02:17 +0000	[thread overview]
Message-ID: <20230316200219.42673-1-joao.m.martins@oracle.com> (raw)

Hey,

This small series expands from v1 with one more patch:

Patch 1) Fix affinity changes to already-in-guest-mode IRTEs which would
         otherwise be nops.

Patch 2) Handle the GALog overflow condition by restarting it

I have a follow-up 3-patch series but being an potential optimization[0]
I prefer making it separate. This series just tackles bugs.

Comments appreciated.

Thanks,
	Joao

Changes since v1[1]:
- Adjust commit message in first patch (Suravee)
- Add Rb in the first patch (Suravee)
