From e74c8a461139b41075ede68f40c313a268445284 Mon Sep 17 00:00:00 2001 From: Joshua Aberback Date: Mon, 31 Aug 2020 01:58:03 -0400 Subject: [PATCH] drm/amd/display: Update idle optimization handling [How] - use dc interface instead of hwss interface in cursor functions, to keep dc->idle_optimizations_allowed updated - add dc interface to check if idle optimizations might apply to a plane Signed-off-by: Joshua Aberback Acked-by: Alex Deucher Reviewed-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/display/dc/core/dc.c | 6 ++++-- drivers/gpu/drm/amd/display/dc/dc.h | 4 ++++ drivers/gpu/drm/amd/display/dc/dc_hw_types.h | 1 + drivers/gpu/drm/amd/display/dc/dcn30/dcn30_hwseq.c | 13 +++++++++++++ drivers/gpu/drm/amd/display/dc/dcn30/dcn30_hwseq.h | 2 ++ drivers/gpu/drm/amd/display/dc/dcn30/dcn30_init.c | 1 + .../gpu/drm/amd/display/dc/dcn30/dcn30_resource.c | 4 ++++ drivers/gpu/drm/amd/display/dc/inc/hw_sequencer.h | 2 ++ 8 files changed, 31 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/amd/display/dc/core/dc.c b/drivers/gpu/drm/amd/display/dc/core/dc.c index cf0bcf674a91..8f1cadb823c7 100644 --- a/drivers/gpu/drm/amd/display/dc/core/dc.c +++ b/drivers/gpu/drm/amd/display/dc/core/dc.c @@ -3138,9 +3138,11 @@ void dc_lock_memory_clock_frequency(struct dc *dc) core_link_enable_stream(dc->current_state, &dc->current_state->res_ctx.pipe_ctx[i]); } -bool dc_is_plane_eligible_for_idle_optimizaitons(struct dc *dc, - struct dc_plane_state *plane) +bool dc_is_plane_eligible_for_idle_optimizaitons(struct dc *dc, struct dc_plane_state *plane) { + if (dc->hwss.does_plane_fit_in_mall && dc->hwss.does_plane_fit_in_mall(dc, plane)) + return true; + return false; } diff --git a/drivers/gpu/drm/amd/display/dc/dc.h b/drivers/gpu/drm/amd/display/dc/dc.h index 3aedadb34548..90fdddb72e3b 100644 --- a/drivers/gpu/drm/amd/display/dc/dc.h +++ b/drivers/gpu/drm/amd/display/dc/dc.h @@ -171,6 +171,9 @@ struct dc_caps { bool dmcub_support; uint32_t num_of_internal_disp; enum dp_protocol_version max_dp_protocol_version; + unsigned int mall_size_per_mem_channel; + unsigned int mall_size_total; + unsigned int cursor_cache_size; struct dc_plane_cap planes[MAX_PLANES]; struct dc_color_caps color; }; @@ -499,6 +502,7 @@ struct dc_debug_options { bool dmcub_emulation; #if defined(CONFIG_DRM_AMD_DC_DCN) bool disable_idle_power_optimizations; + unsigned int mall_size_override; #endif bool dmub_command_table; /* for testing only */ struct dc_bw_validation_profile bw_val_profile; diff --git a/drivers/gpu/drm/amd/display/dc/dc_hw_types.h b/drivers/gpu/drm/amd/display/dc/dc_hw_types.h index 701aa7178a89..b41e6367b15e 100644 --- a/drivers/gpu/drm/amd/display/dc/dc_hw_types.h +++ b/drivers/gpu/drm/amd/display/dc/dc_hw_types.h @@ -71,6 +71,7 @@ struct dc_plane_address { union { struct{ PHYSICAL_ADDRESS_LOC addr; + PHYSICAL_ADDRESS_LOC cursor_cache_addr; PHYSICAL_ADDRESS_LOC meta_addr; union large_integer dcc_const_color; } grph; diff --git a/drivers/gpu/drm/amd/display/dc/dcn30/dcn30_hwseq.c b/drivers/gpu/drm/amd/display/dc/dcn30/dcn30_hwseq.c index 3deb3fb1724d..b83c13d3d8b7 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn30/dcn30_hwseq.c +++ b/drivers/gpu/drm/amd/display/dc/dcn30/dcn30_hwseq.c @@ -814,6 +814,19 @@ bool dcn30_apply_idle_power_optimizations(struct dc *dc, bool enable) return true; } +bool dcn30_does_plane_fit_in_mall(struct dc *dc, struct dc_plane_state *plane) +{ + // add meta size?
