Subject: [PATCH 0/4] IOMMU/PCI: respect device specifics
Date: Wed, 15 Sep 2021 11:11:13 +0200 [thread overview]
Message-ID: <6b7fa64a-bd6b-353c-30cb-ec25b850cbed@suse.com> (raw)
While making the first change here it occurred to me that the recent
vPCI-related discussion about hidden devices has some relevance also
elsewhere. In the course I then came to also notice a phantom device
related quirk.
1: VT-d: defer "no DRHD" check when (un)mapping devices
2: VT-d: consider hidden devices when unmapping
3: VT-d: skip IOMMU bitmap cleanup for phantom devices
4: AMD/IOMMU: consider hidden devices when flushing device I/O TLBs

(I'm sorry for the resend, but I thought I would better add the
previously missing tag.)
