Subject: [PATCH v3 0/2] drm: Fix dma_resv deadlock at drm object pin time
This is v3 of https://lore.kernel.org/dri-devel/20240424090429.57de7d1c@collabora.com/
The goal of this patch series is fixing a deadlock upon locking the dma reservation
of a DRM gem object when pinning it, at a prime import operation.
Changes from v2:
- Removed comment explaining reason why an already-locked
pin function replaced the locked variant inside Panfrost's
object pin callback.
- Moved already-assigned attachment warning into generic
already-locked gem object pin function
Adrián Larumbe (2):
drm/panfrost: Fix dma_resv deadlock at drm object pin time
drm/gem-shmem: Add import attachment warning to locked pin function
