This is v3 of https://lore.kernel.org/dri-devel/20240424090429.57de7d1c@xxxxxxxxxxxxx/ 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 drivers/gpu/drm/drm_gem_shmem_helper.c | 2 ++ drivers/gpu/drm/lima/lima_gem.c | 2 +- drivers/gpu/drm/panfrost/panfrost_gem.c | 2 +- 3 files changed, 4 insertions(+), 2 deletions(-) base-commit: 75b68f22e39aafb22f3d8e3071e1aba73560788c -- 2.44.0
