Subject: [PATCH] drm/nouveau: Fix bug in buffer relocs for Nouveau
Date: Thu, 19 Jan 2023 23:53:51 +0100 [thread overview]
Message-ID: <20230119225351.71657-1-007047221b@gmail.com> (raw)
dma_resv_wait_timeout returns greater than zero on success
as opposed to ttm_bo_wait_ctx. As a result of that relocs
will fail and give failure even when it was a success.
