From 73511edf8b196e6f1ccda0fdf294ff57aa2dc9db Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20K=C3=B6nig?= Date: Tue, 9 Nov 2021 11:08:18 +0100 Subject: dma-buf: specify usage while adding fences to dma_resv obj v7 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of distingting between shared and exclusive fences specify the fence usage while adding fences. Rework all drivers to use this interface instead and deprecate the old one. v2: some kerneldoc comments suggested by Daniel v3: fix a missing case in radeon v4: rebase on nouveau changes, fix lockdep and temporary disable warning v5: more documentation updates v6: separate internal dma_resv changes from this patch, avoids to disable warning temporary, rebase on upstream changes v7: fix missed case in lima driver, minimize changes to i915_gem_busy_ioctl Signed-off-by: Christian König Reviewed-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20220407085946.744568-3-christian.koenig@amd.com --- drivers/gpu/drm/lima/lima_gem.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'drivers/gpu/drm/lima/lima_gem.c') diff --git a/drivers/gpu/drm/lima/lima_gem.c b/drivers/gpu/drm/lima/lima_gem.c index e0a11ee0e86d..0f1ca0b0db49 100644 --- a/drivers/gpu/drm/lima/lima_gem.c +++ b/drivers/gpu/drm/lima/lima_gem.c @@ -364,10 +364,9 @@ int lima_gem_submit(struct drm_file *file, struct lima_submit *submit) fence = lima_sched_context_queue_task(submit->task); for (i = 0; i < submit->nr_bos; i++) { - if (submit->bos[i].flags & LIMA_SUBMIT_BO_WRITE) - dma_resv_add_excl_fence(lima_bo_resv(bos[i]), fence); - else - dma_resv_add_shared_fence(lima_bo_resv(bos[i]), fence); + dma_resv_add_fence(lima_bo_resv(bos[i]), fence, + submit->bos[i].flags & LIMA_SUBMIT_BO_WRITE ? + DMA_RESV_USAGE_WRITE : DMA_RESV_USAGE_READ); } drm_gem_unlock_reservations((struct drm_gem_object **)bos, -- cgit v1.2.3
