From f38129bb081758176dd78304faaee95007fb8838 Mon Sep 17 00:00:00 2001 From: Aurabindo Pillai Date: Tue, 21 Mar 2023 10:25:04 -0400 Subject: [PATCH] Revert "drm/amd/display: disable SubVP + DRR to prevent underflow" This reverts commit 80c6d6804f31451848a3956a70c2bcb1f07cfcb0. The orignal commit was intended as a workaround to prevent underflow and flickering when using one normal monitor and the other high refresh rate monitor (> 120Hz). This patch is being reverted in favour of a software solution to enable SubVP+DRR Signed-off-by: Aurabindo Pillai Reviewed-by: Rodrigo Siqueira Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 5 ----- drivers/gpu/drm/amd/display/dc/dml/dcn32/dcn32_fpu.c | 4 ---- drivers/gpu/drm/amd/include/amd_shared.h | 1 - 3 files changed, 10 deletions(-) diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index 7f0dcd7af4c7..dd56e1512b0a 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -1646,11 +1646,6 @@ static int amdgpu_dm_init(struct amdgpu_device *adev) if (amdgpu_dc_feature_mask & DC_DISABLE_LTTPR_DP2_0) init_data.flags.allow_lttpr_non_transparent_mode.bits.DP2_0 = true; - /* Disable SubVP + DRR config by default */ - init_data.flags.disable_subvp_drr = true; - if (amdgpu_dc_feature_mask & DC_ENABLE_SUBVP_DRR) - init_data.flags.disable_subvp_drr = false; - init_data.flags.seamless_boot_edp_requested = false; if (check_seamless_boot_capability(adev)) { diff --git a/drivers/gpu/drm/amd/display/dc/dml/dcn32/dcn32_fpu.c b/drivers/gpu/drm/amd/display/dc/dml/dcn32/dcn32_fpu.c index a73cacef6e48..826059d5b367 100644 --- a/drivers/gpu/drm/amd/display/dc/dml/dcn32/dcn32_fpu.c +++ b/drivers/gpu/drm/amd/display/dc/dml/dcn32/dcn32_fpu.c @@ -892,10 +892,6 @@ static bool subvp_drr_schedulable(struct dc *dc, struct dc_state *context, struc int16_t stretched_drr_us = 0; int16_t drr_stretched_vblank_us = 0; int16_t max_vblank_mallregion = 0; - const struct dc_config *config = &dc->config; - - if (config->disable_subvp_drr) - return false; // Find SubVP pipe for (i = 0; i < dc->res_pool->pipe_count; i++) { diff --git a/drivers/gpu/drm/amd/include/amd_shared.h b/drivers/gpu/drm/amd/include/amd_shared.h index e4a22c68517d..f175e65b853a 100644 --- a/drivers/gpu/drm/amd/include/amd_shared.h +++ b/drivers/gpu/drm/amd/include/amd_shared.h @@ -240,7 +240,6 @@ enum DC_FEATURE_MASK { DC_DISABLE_LTTPR_DP2_0 = (1 << 6), //0x40, disabled by default DC_PSR_ALLOW_SMU_OPT = (1 << 7), //0x80, disabled by default DC_PSR_ALLOW_MULTI_DISP_OPT = (1 << 8), //0x100, disabled by default - DC_ENABLE_SUBVP_DRR = (1 << 9), // 0x200, disabled by default }; enum DC_DEBUG_MASK { -- 2.25.1
