From: Jesse Zhang <jesse.zhang@xxxxxxx> commit 88a9a467c548d0b3c7761b4fd54a68e70f9c0944 upstream. Initialize the size before calling amdgpu_vce_cs_reloc, such as case 0x03000001. V2: To really improve the handling we would actually need to have a separate value of 0xffffffff.(Christian) Signed-off-by: Jesse Zhang <jesse.zhang@xxxxxxx> Suggested-by: Christian König <christian.koenig@xxxxxxx> Reviewed-by: Christian König <christian.koenig@xxxxxxx> Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> Signed-off-by: Vamsi Krishna Brahmajosyula <vamsi-krishna.brahmajosyula@xxxxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c @@ -715,7 +715,8 @@ int amdgpu_vce_ring_parse_cs(struct amdg uint32_t created = 0; uint32_t allocated = 0; uint32_t tmp, handle = 0; - uint32_t *size = &tmp; + uint32_t dummy = 0xffffffff; + uint32_t *size = &dummy; unsigned idx; int i, r = 0; Patches currently in stable-queue which might be from jesse.zhang@xxxxxxx are queue-5.4/drm-amdgpu-using-uninitialized-value-size-when-calling-amdgpu_vce_cs_reloc.patch
