Subject: [PATCH 4/5] drm/ttm: move the LRU into resource handling
Date: Mon, 19 Jul 2021 13:51:44 +0200 [thread overview]
Message-ID: <20210719115145.1260-4-christian.koenig@amd.com> (raw)
In-Reply-To: <20210719115145.1260-1-christian.koenig@amd.com>
This way we finally fix the problem that new resource are
not immediately evict-able after allocation.
That has caused numerous problems including OOM on GDS handling
and not being able to use TTM as general resource manager.
