Issue reported on SC7280: With wait-for-safe feature in smmu enabled, RT client buffer levels are checked to be safe before smmu invalidation. Since display was always set to unsafe it was delaying the invalidaiton process thus impacting the performance on NRT clients such as eMMC and NVMe. Validated this change on SC7280, With this change eMMC performance has improved significantly. Changes in v1: - Add fixes tag (Sai) - CC stable kernel (Dimtry) Changes in v2: - Correct fixes tag with appropriate hash (stephen) Fixes: 591e34a091d1 (drm/msm/disp/dpu1: add support for display for SC7280 target) Signed-off-by: Kalyan Thota Tested-by: Sai Prakash Ranjan (sc7280, sc7180) --- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c index d01c4c9..2e482cd 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c @@ -974,6 +974,7 @@ static const struct dpu_perf_cfg sdm845_perf_data = { .amortizable_threshold = 25, .min_prefill_lines = 24, .danger_lut_tbl = {0xf, 0xffff, 0x0}, + .safe_lut_tbl = {0xfff0, 0xf000, 0xffff}, .qos_lut_tbl = { {.nentry = ARRAY_SIZE(sdm845_qos_linear), .entries = sdm845_qos_linear @@ -1001,6 +1002,7 @@ static const struct dpu_perf_cfg sc7180_perf_data = { .min_dram_ib = 1600000, .min_prefill_lines = 24, .danger_lut_tbl = {0xff, 0xffff, 0x0}, + .safe_lut_tbl = {0xfff0, 0xff00, 0xffff}, .qos_lut_tbl = { {.nentry = ARRAY_SIZE(sc7180_qos_linear), .entries = sc7180_qos_linear @@ -1028,6 +1030,7 @@ static const struct dpu_perf_cfg sm8150_perf_data = { .min_dram_ib = 800000, .min_prefill_lines = 24, .danger_lut_tbl = {0xf, 0xffff, 0x0}, + .safe_lut_tbl = {0xfff8, 0xf000, 0xffff}, .qos_lut_tbl = { {.nentry = ARRAY_SIZE(sm8150_qos_linear), .entries = sm8150_qos_linear @@ -1056,6 +1059,7 @@ static const struct dpu_perf_cfg sm8250_perf_data = { .min_dram_ib = 800000, .min_prefill_lines = 35, .danger_lut_tbl = {0xf, 0xffff, 0x0}, + .safe_lut_tbl = {0xfff0, 0xff00, 0xffff}, .qos_lut_tbl = { {.nentry = ARRAY_SIZE(sc7180_qos_linear), .entries = sc7180_qos_linear @@ -1084,6 +1088,7 @@ static const struct dpu_perf_cfg sc7280_perf_data = { .min_dram_ib = 1600000, .min_prefill_lines = 24, .danger_lut_tbl = {0xffff, 0xffff, 0x0}, + .safe_lut_tbl = {0xff00, 0xff00, 0xffff}, .qos_lut_tbl = { {.nentry = ARRAY_SIZE(sc7180_qos_macrotile), .entries = sc7180_qos_macrotile
