From 522f82f35fd0057cae326ad21a5f93a221b08b25 Mon Sep 17 00:00:00 2001 From: Anthony Koo Date: Wed, 30 Jan 2019 16:14:38 -0500 Subject: [PATCH] drm/amd/display: make seamless boot work generically [Why] Seamless boot code not working on all ASICs because of some underflow issues caused by some uninitialized HW state. [How] Keep some logical and power gating init code in hw_init. Move some per pipe init code to enable accelerated mode Signed-off-by: Anthony Koo Reviewed-by: Aric Cyr Acked-by: Leo Li Signed-off-by: Alex Deucher --- .../display/dc/dce110/dce110_hw_sequencer.c | 3 ++ .../amd/display/dc/dcn10/dcn10_hw_sequencer.c | 35 +++++++++++++------ 2 files changed, 27 insertions(+), 11 deletions(-) diff --git a/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c b/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c index 5c7fb92d081c..21a621822a59 100644 --- a/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c +++ b/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c @@ -1551,6 +1551,9 @@ void dce110_enable_accelerated_mode(struct dc *dc, struct dc_state *context) } } + if (dc->hwss.init_pipes) + dc->hwss.init_pipes(dc, context); + if (edp_link) { /* this seems to cause blank screens on DCE8 */ if ((dc->ctx->dce_version == DCE_VERSION_8_0) || diff --git a/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c index 8ba895c4b445..62a059d99d33 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c +++ b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c @@ -889,22 +889,23 @@ void hwss1_plane_atomic_disconnect(struct dc *dc, struct pipe_ctx *pipe_ctx) dcn10_verify_allow_pstate_change_high(dc); } -static void plane_atomic_power_down(struct dc *dc, struct pipe_ctx *pipe_ctx) +static void plane_atomic_power_down(struct dc *dc, + struct dpp *dpp, + struct hubp *hubp) { struct dce_hwseq *hws = dc->hwseq; - struct dpp *dpp = pipe_ctx->plane_res.dpp; DC_LOGGER_INIT(dc->ctx->logger); if (REG(DC_IP_REQUEST_CNTL)) { REG_SET(DC_IP_REQUEST_CNTL, 0, IP_REQUEST_EN, 1); dpp_pg_control(hws, dpp->inst, false); - hubp_pg_control(hws, pipe_ctx->plane_res.hubp->inst, false); + hubp_pg_control(hws, hubp->inst, false); dpp->funcs->dpp_reset(dpp); REG_SET(DC_IP_REQUEST_CNTL, 0, IP_REQUEST_EN, 0); DC_LOG_DEBUG( - "Power gated front end %d\n", pipe_ctx->pipe_idx); + "Power gated front end %d\n", hubp->inst); } } @@ -931,7 +932,9 @@ static void plane_atomic_disable(struct dc *dc, struct pipe_ctx *pipe_ctx) hubp->power_gated = true; dc->optimized_required = false; /* We're powering off, no need to optimize */ - plane_atomic_power_down(dc, pipe_ctx); + plane_atomic_power_down(dc, + pipe_ctx->plane_res.dpp, + pipe_ctx->plane_res.hubp); pipe_ctx->stream = NULL; memset(&pipe_ctx->stream_res, 0, sizeof(pipe_ctx->stream_res)); @@ -1001,9 +1004,6 @@ static void dcn10_init_pipes(struct dc *dc, struct dc_state *context) struct dpp *dpp = dc->res_pool->dpps[i]; struct pipe_ctx *pipe_ctx = &context->res_ctx.pipe_ctx[i]; - // W/A for issue with dc_post_update_surfaces_to_stream - hubp->power_gated = true; - /* There is assumption that pipe_ctx is not mapping irregularly * to non-preferred front end.
