From 9d3afcb7b9f950b9b7c58ceeeb9e71f3476e69ed Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Tue, 27 Aug 2024 15:29:49 +0530 Subject: [PATCH 3062/5403] drm/amdgpu: fix MES GFX mask MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Current MES GFX mask prevents FW to enable oversubscription. This patch does the following: - Fixes the mask values and adds a description for the same - Removes the central mask setup and makes it IP specific, as it would be different when the number of pipes and queues are different. v2: squash in fix from Shashank Cc: Christian König Cc: Alex Deucher Acked-by: Christian König Signed-off-by: Shashank Sharma Signed-off-by: Arvind Yadav Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c | 3 --- drivers/gpu/drm/amd/amdgpu/amdgpu_mes.h | 2 +- drivers/gpu/drm/amd/amdgpu/mes_v11_0.c | 15 +++++++++++++-- drivers/gpu/drm/amd/amdgpu/mes_v12_0.c | 15 ++++++++++++--- 4 files changed, 26 insertions(+), 9 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c index 85f774063f9b..f8202e6ed4b1 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c @@ -150,9 +150,6 @@ int amdgpu_mes_init(struct amdgpu_device *adev) adev->mes.compute_hqd_mask[i] = 0xc; } - for (i = 0; i < AMDGPU_MES_MAX_GFX_PIPES; i++) - adev->mes.gfx_hqd_mask[i] = i ? 0 : 0xfffffffe; - for (i = 0; i < AMDGPU_MES_MAX_SDMA_PIPES; i++) { if (i >= adev->sdma.num_instances) break; diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.h index da2c9a8cb3e0..52dd54a32fb4 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.h @@ -111,8 +111,8 @@ struct amdgpu_mes { uint32_t vmid_mask_gfxhub; uint32_t vmid_mask_mmhub; - uint32_t compute_hqd_mask[AMDGPU_MES_MAX_COMPUTE_PIPES]; uint32_t gfx_hqd_mask[AMDGPU_MES_MAX_GFX_PIPES]; + uint32_t compute_hqd_mask[AMDGPU_MES_MAX_COMPUTE_PIPES]; uint32_t sdma_hqd_mask[AMDGPU_MES_MAX_SDMA_PIPES]; uint32_t aggregated_doorbells[AMDGPU_MES_PRIORITY_NUM_LEVELS]; uint32_t sch_ctx_offs[AMDGPU_MAX_MES_PIPES]; diff --git a/drivers/gpu/drm/amd/amdgpu/mes_v11_0.c b/drivers/gpu/drm/amd/amdgpu/mes_v11_0.c index c34a00500e18..4cfd86aa2ea3 100644 --- a/drivers/gpu/drm/amd/amdgpu/mes_v11_0.c +++ b/drivers/gpu/drm/amd/amdgpu/mes_v11_0.c @@ -669,6 +669,18 @@ static int mes_v11_0_misc_op(struct amdgpu_mes *mes, offsetof(union MESAPI__MISC, api_status)); } +static void mes_v11_0_set_gfx_hqd_mask(union MESAPI_SET_HW_RESOURCES *pkt) +{ + /* + * GFX pipe 0 queue 0 is being used by Kernel queue. + * Set GFX pipe 0 queue 1 for MES scheduling + * mask = 10b + * GFX pipe 1 can't be used for MES due to HW limitation. + */ + pkt->gfx_hqd_mask[0] = 0x2; + pkt->gfx_hqd_mask[1] = 0; +} + static int mes_v11_0_set_hw_resources(struct amdgpu_mes *mes) { int i; @@ -693,8 +705,7 @@ static int mes_v11_0_set_hw_resources(struct amdgpu_mes *mes) mes_set_hw_res_pkt.compute_hqd_mask[i] = mes->compute_hqd_mask[i]; - for (i = 0; i < MAX_GFX_PIPES; i++) - mes_set_hw_res_pkt.gfx_hqd_mask[i] = mes->gfx_hqd_mask[i]; + mes_v11_0_set_gfx_hqd_mask(&mes_set_hw_res_pkt); for (i = 0; i < MAX_SDMA_PIPES; i++) mes_set_hw_res_pkt.sdma_hqd_mask[i] = mes->sdma_hqd_mask[i]; diff --git a/drivers/gpu/drm/amd/amdgpu/mes_v12_0.c b/drivers/gpu/drm/amd/amdgpu/mes_v12_0.c index e6ab617b9a40..62aba0b5dbe2 100644 --- a/drivers/gpu/drm/amd/amdgpu/mes_v12_0.c +++ b/drivers/gpu/drm/amd/amdgpu/mes_v12_0.c @@ -694,6 +694,17 @@ static int mes_v12_0_set_hw_resources_1(struct amdgpu_mes *mes, int pipe) offsetof(union MESAPI_SET_HW_RESOURCES_1, api_status)); } +static void mes_v12_0_set_gfx_hqd_mask(union MESAPI_SET_HW_RESOURCES *pkt) +{ + /* + * GFX V12 has only one GFX pipe, but 8 queues in it. + * GFX pipe 0 queue 0 is being used by Kernel queue. + * Set GFX pipe 0 queue 1-7 for MES scheduling + * mask = 1111 1110b + */ + pkt->gfx_hqd_mask[0] = 0xFE; +} + static int mes_v12_0_set_hw_resources(struct amdgpu_mes *mes, int pipe) { int i; @@ -716,9 +727,7 @@ static int mes_v12_0_set_hw_resources(struct amdgpu_mes *mes, int pipe) mes_set_hw_res_pkt.compute_hqd_mask[i] = mes->compute_hqd_mask[i]; - for (i = 0; i < MAX_GFX_PIPES; i++) - mes_set_hw_res_pkt.gfx_hqd_mask[i] = - mes->gfx_hqd_mask[i]; + mes_v12_0_set_gfx_hqd_mask(&mes_set_hw_res_pkt); for (i = 0; i < MAX_SDMA_PIPES; i++) mes_set_hw_res_pkt.sdma_hqd_mask[i] = -- 2.54.0
