Subject: [PATCH 0/3][4.16?] VT-d: misc (regression) fixes
Date: Tue, 9 Nov 2021 15:55:38 +0100 [thread overview]
Message-ID: <d8295304-d81d-1d11-9bc2-d2539bf5a96a@suse.com> (raw)
1: per-domain IOMMU bitmap needs to have dynamic size
2: fix reduced page table levels support when sharing tables
3: don't needlessly engage the untrusted-MSI workaround
As to 4.16 considerations: Only patch 1 addresses a regression
introduced after 4.15, the others are older. Patch 3 additionally
only addresses an inefficiency; the code we have is correct from
a functional pov.
