From c8e7e3c2215e286ebfe66fe828ed426546c519e6 Mon Sep 17 00:00:00 2001 From: Srinivasan Shanmugam Date: Tue, 25 Nov 2025 21:20:45 +0530 Subject: [PATCH] drm/amdgpu/sdma6: Update SDMA 6.0.3 FW version to include UMQ protected-fence fix MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On GFX11.0.3, earlier SDMA firmware versions issue the PROTECTED_FENCE write from the user VMID (e.g. VMID 8) instead of VMID 0. This causes a GPU VM protection fault when SDMA tries to write the secure fence location, as seen in the UMQ SDMA test (cs-sdma-with-IP-DMA-UMQ) Fixes the below GPU page fault: [ 514.037189] amdgpu 0000:0b:00.0: amdgpu: [gfxhub] page fault (src_id:0 ring:40 vmid:8 pasid:32770) [ 514.037199] amdgpu 0000:0b:00.0: amdgpu: Process pid 0 thread pid 0 [ 514.037205] amdgpu 0000:0b:00.0: amdgpu: in page starting at address 0x00007fff00409000 from client 10 [ 514.037212] amdgpu 0000:0b:00.0: amdgpu: GCVM_L2_PROTECTION_FAULT_STATUS:0x00841A51 [ 514.037217] amdgpu 0000:0b:00.0: amdgpu: Faulty UTCL2 client ID: SDMA0 (0xd) [ 514.037223] amdgpu 0000:0b:00.0: amdgpu: MORE_FAULTS: 0x1 [ 514.037227] amdgpu 0000:0b:00.0: amdgpu: WALKER_ERROR: 0x0 [ 514.037232] amdgpu 0000:0b:00.0: amdgpu: PERMISSION_FAULTS: 0x5 [ 514.037236] amdgpu 0000:0b:00.0: amdgpu: MAPPING_ERROR: 0x0 [ 514.037241] amdgpu 0000:0b:00.0: amdgpu: RW: 0x1 v2: Updated commit message v3: s/gfx11.0.3/sdma 6.0.3/ in patch title (Alex) Cc: Alex Deucher Cc: Christian König Cc: stable@vger.kernel.org Signed-off-by: Srinivasan Shanmugam Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/sdma_v6_0.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/amdgpu/sdma_v6_0.c b/drivers/gpu/drm/amd/amdgpu/sdma_v6_0.c index 0ceeb19df2e5..217040044987 100644 --- a/drivers/gpu/drm/amd/amdgpu/sdma_v6_0.c +++ b/drivers/gpu/drm/amd/amdgpu/sdma_v6_0.c @@ -1390,7 +1390,7 @@ static int sdma_v6_0_sw_init(struct amdgpu_ip_block *ip_block) adev->userq_funcs[AMDGPU_HW_IP_DMA] = &userq_mes_funcs; break; case IP_VERSION(6, 0, 3): - if ((adev->sdma.instance[0].fw_version >= 27) && !adev->sdma.disable_uq) + if (adev->sdma.instance[0].fw_version >= 29 && !adev->sdma.disable_uq) adev->userq_funcs[AMDGPU_HW_IP_DMA] = &userq_mes_funcs; break; case IP_VERSION(6, 1, 0): -- 2.47.3
