From 73511edf8b196e6f1ccda0fdf294ff57aa2dc9db Mon Sep 17 00:00:00 2001 From: Christian König 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/i915/i915_vma.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'drivers/gpu/drm/i915/i915_vma.c') diff --git a/drivers/gpu/drm/i915/i915_vma.c b/drivers/gpu/drm/i915/i915_vma.c index bae3423f58e8..524477d8939e 100644 --- a/drivers/gpu/drm/i915/i915_vma.c +++ b/drivers/gpu/drm/i915/i915_vma.c @@ -1826,7 +1826,8 @@ int _i915_vma_move_to_active(struct i915_vma *vma, } if (fence) { - dma_resv_add_excl_fence(vma->obj->base.resv, fence); + dma_resv_add_fence(vma->obj->base.resv, fence, + DMA_RESV_USAGE_WRITE); obj->write_domain = I915_GEM_DOMAIN_RENDER; obj->read_domains = 0; } @@ -1838,7 +1839,8 @@ int _i915_vma_move_to_active(struct i915_vma *vma, } if (fence) { - dma_resv_add_shared_fence(vma->obj->base.resv, fence); + dma_resv_add_fence(vma->obj->base.resv, fence, + DMA_RESV_USAGE_READ); obj->write_domain = 0; } } @@ -2078,7 +2080,7 @@ int i915_vma_unbind_async(struct i915_vma *vma, bool trylock_vm) goto out_rpm; } - dma_resv_add_shared_fence(obj->base.resv, fence); + dma_resv_add_fence(obj->base.resv, fence, DMA_RESV_USAGE_READ); dma_fence_put(fence); out_rpm: -- cgit v1.2.3
