From 3676f37a88432132bcff55a17dc48911239b6d98 Mon Sep 17 00:00:00 2001 From: Bokun Zhang Date: Wed, 11 Dec 2024 15:42:56 -0600 Subject: [PATCH 1256/5403] drm/amdgpu/vcn: reset fw_shared under SRIOV - The previous patch only considered the case for baremetal and is not applicable for SRIOV code path. We also need to init fw_share for SRIOV VF Fixes: 928cd772e18f ("drm/amdgpu/vcn: reset fw_shared when VCPU buffers corrupted on vcn v4.0.3") Acked-by: Alex Deucher Signed-off-by: Bokun Zhang Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/vcn_v4_0_3.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/gpu/drm/amd/amdgpu/vcn_v4_0_3.c b/drivers/gpu/drm/amd/amdgpu/vcn_v4_0_3.c index eeade7366e82..ecdc027f8220 100644 --- a/drivers/gpu/drm/amd/amdgpu/vcn_v4_0_3.c +++ b/drivers/gpu/drm/amd/amdgpu/vcn_v4_0_3.c @@ -957,6 +957,8 @@ static int vcn_v4_0_3_start_sriov(struct amdgpu_device *adev) for (i = 0; i < adev->vcn.num_vcn_inst; i++) { vcn_inst = GET_INST(VCN, i); + vcn_v4_0_3_fw_shared_init(adev, vcn_inst); + memset(&header, 0, sizeof(struct mmsch_v4_0_3_init_header)); header.version = MMSCH_VERSION; header.total_size = sizeof(struct mmsch_v4_0_3_init_header) >> 2; -- 2.54.0
