From 6edbd6abb783d54f6ac4c3ed5cd9e50cff6c15e9 Mon Sep 17 00:00:00 2001 From: Christian König Date: Mon, 10 May 2021 16:14:09 +0200 Subject: dma-buf: rename and cleanup dma_resv_get_excl v3 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When the comment needs to state explicitly that this doesn't get a reference to the object then the function is named rather badly. Rename the function and use rcu_dereference_check(), this way it can be used from both rcu as well as lock protected critical sections. v2: improve kerneldoc as suggested by Daniel v3: use dma_resv_excl_fence as function name Signed-off-by: Christian König Acked-by: Daniel Vetter Reviewed-by: Jason Ekstrand Link: https://patchwork.freedesktop.org/patch/msgid/20210602111714.212426-4-christian.koenig@amd.com --- drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c index 73c76a3e2b12..7d5aaf584634 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c @@ -226,7 +226,7 @@ static void amdgpu_gem_object_close(struct drm_gem_object *obj, if (!amdgpu_vm_ready(vm)) goto out_unlock; - fence = dma_resv_get_excl(bo->tbo.base.resv); + fence = dma_resv_excl_fence(bo->tbo.base.resv); if (fence) { amdgpu_bo_fence(bo, fence, true); fence = NULL; -- cgit From d3fae3b3daac09961ab871a25093b0ae404282d5 Mon Sep 17 00:00:00 2001 From: Christian König Date: Wed, 2 Jun 2021 13:01:15 +0200 Subject: dma-buf: drop the _rcu postfix on function names v3 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The functions can be called both in _rcu context as well as while holding the lock. v2: add some kerneldoc as suggested by Daniel v3: fix indentation Signed-off-by: Christian König Reviewed-by: Jason Ekstrand Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20210602111714.212426-7-christian.koenig@amd.com --- drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c index 7d5aaf584634..1c3e3b608332 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c @@ -526,8 +526,7 @@ int amdgpu_gem_wait_idle_ioctl(struct drm_device *dev, void *data, return -ENOENT; } robj = gem_to_amdgpu_bo(gobj); - ret = dma_resv_wait_timeout_rcu(robj->tbo.base.resv, true, true, - timeout); + ret = dma_resv_wait_timeout(robj->tbo.base.resv, true, true, timeout); /* ret == 0 means not signaled, * ret > 0 means signaled -- cgit
