Subject: [PATCH drm-misc-next] drm/nouveau: uvmm: fix unset region pointer on remap
Date: Mon, 21 Aug 2023 00:29:16 +0200 [thread overview]
Message-ID: <20230820222920.2344-1-dakr@redhat.com> (raw)
Transfer the region pointer of a uvma to the new uvma(s) on re-map to
prevent potential shader faults when the re-mapped uvma(s) are unmapped.
