Subject: [PATCH 0/6] VT-d: domain ID mapping improvements
Date: Fri, 12 Nov 2021 10:46:48 +0100	[thread overview]
Message-ID: <a97adc3d-2808-1c87-8fd6-d6b24b83bd2b@suse.com> (raw)

Two bug fixes, some cleanup, and a simplification for modern hardware.

1: properly reserve DID 0 for caching mode IOMMUs
2: split domid map cleanup check into a function
3: don't leak domid mapping on error path
4: tidy domid map handling
5: introduce helper to convert DID to domid_t
6: avoid allocating domid_{bit,}map[] when possible

This depends on the previously submitted (and already approved, except
for a possible release ack) "VT-d: per-domain IOMMU bitmap needs to
have dynamic size".
