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_gfx.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c index a819360a4b6a..ebea3f655826 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c @@ -719,7 +719,7 @@ uint32_t amdgpu_kiq_rreg(struct amdgpu_device *adev, uint32_t reg) * * also don't wait anymore for IRQ context * */ - if (r < 1 && (adev->in_gpu_reset || in_interrupt())) + if (r < 1 && (amdgpu_in_reset(adev) || in_interrupt())) goto failed_kiq_read; might_sleep(); @@ -777,7 +777,7 @@ void amdgpu_kiq_wreg(struct amdgpu_device *adev, uint32_t reg, uint32_t v) * * also don't wait anymore for IRQ context * */ - if (r < 1 && (adev->in_gpu_reset || in_interrupt())) + if (r < 1 && (amdgpu_in_reset(adev) || in_interrupt())) goto failed_kiq_write; might_sleep(); -- cgit v1.2.3-70-g09d2
