From 53b3f8f40e6cff36ae12b11e6d6b308af3c7e53f Mon Sep 17 00:00:00 2001 From: Dennis Li Date: Wed, 19 Aug 2020 17:23:03 +0800 Subject: drm/amdgpu: refine codes to avoid reentering GPU recovery if other threads have holden the reset lock, recovery will fail to try_lock. Therefore we introduce atomic hive->in_reset and adev->in_gpu_reset, to avoid reentering GPU recovery. v2: drop "? true : false" in the definition of amdgpu_in_reset Reviewed-by: Hawking Zhang Signed-off-by: Dennis Li Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c index 35fed75a4397..79b397800cbc 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c @@ -127,7 +127,7 @@ static unsigned int amdgpu_debugfs_autodump_poll(struct file *file, struct poll_ poll_wait(file, &adev->autodump.gpu_hang, poll_table); - if (adev->in_gpu_reset) + if (amdgpu_in_reset(adev)) return POLLIN | POLLRDNORM | POLLWRNORM; return 0; -- cgit v1.2.3
