From: Aurabindo Pillai <aurabindo.pillai@xxxxxxx> [ Upstream commit f38129bb081758176dd78304faaee95007fb8838 ] 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 <aurabindo.pillai@xxxxxxx> Reviewed-by: Rodrigo Siqueira <Rodrigo.Siqueira@xxxxxxx> Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- 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 7acd73e5004fb..80756c7b92a54 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 0c4c3208def17..d7eca24bd09d2 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 @@ -880,10 +880,6 @@ 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 e4a22c68517d1..f175e65b853a0 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 { -- 2.39.2
