From e16bcbb011868abd9ed052f5957b77ad3f79fc67 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 9 Apr 2024 19:34:59 +0300 Subject: [PATCH] drm/i915: Handle joined pipes inside hsw_crtc_disable() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reorganize the crtc disable path to only deal with the master pipes/transcoders in intel_old_crtc_state_disables() and offload the handling of joined pipes to hsw_crtc_disable(). This makes the whole thing much more sensible since we can actually control the order in which we do the per-pipe vs. per-transcoder modeset steps. v2: Use the name 'pipe_crtc' for the per-pipe crtc pointer Tested-by: Vidya Srinivas Reviewed-by: Arun R Murthy Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20240409163502.29633-4-ville.syrjala@linux.intel.com --- drivers/gpu/drm/i915/display/intel_display.c | 66 ++++++++++++-------- 1 file changed, 40 insertions(+), 26 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_display.c b/drivers/gpu/drm/i915/display/intel_display.c index c1d8f08814ec..303625344d54 100644 --- a/drivers/gpu/drm/i915/display/intel_display.c +++ b/drivers/gpu/drm/i915/display/intel_display.c @@ -1816,29 +1816,28 @@ static void hsw_crtc_disable(struct intel_atomic_state *state, const struct intel_crtc_state *old_crtc_state = intel_atomic_get_old_crtc_state(state, crtc); struct drm_i915_private *i915 = to_i915(crtc->base.dev); + struct intel_crtc *pipe_crtc; /* * FIXME collapse everything to one hook. * Need care with mst->ddi interactions. */ - if (!intel_crtc_is_bigjoiner_slave(old_crtc_state)) { - intel_encoders_disable(state, crtc); - intel_encoders_post_disable(state, crtc); + intel_encoders_disable(state, crtc); + intel_encoders_post_disable(state, crtc); + + for_each_intel_crtc_in_pipe_mask(&i915->drm, pipe_crtc, + intel_crtc_joined_pipe_mask(old_crtc_state)) { + const struct intel_crtc_state *old_pipe_crtc_state = + intel_atomic_get_old_crtc_state(state, pipe_crtc); + + intel_disable_shared_dpll(old_pipe_crtc_state); } - intel_disable_shared_dpll(old_crtc_state); + intel_encoders_post_pll_disable(state, crtc); - if (!intel_crtc_is_bigjoiner_slave(old_crtc_state)) { - struct intel_crtc *slave_crtc; - - intel_encoders_post_pll_disable(state, crtc); - - intel_dmc_disable_pipe(i915, crtc->pipe); - - for_each_intel_crtc_in_pipe_mask(&i915->drm, slave_crtc, - intel_crtc_bigjoiner_slave_pipes(old_crtc_state)) - intel_dmc_disable_pipe(i915, slave_crtc->pipe); - } + for_each_intel_crtc_in_pipe_mask(&i915->drm, pipe_crtc, + intel_crtc_joined_pipe_mask(old_crtc_state)) + intel_dmc_disable_pipe(i915, pipe_crtc->pipe); } static void i9xx_pfit_enable(const struct intel_crtc_state *crtc_state) @@ -6869,21 +6868,31 @@ static void intel_old_crtc_state_disables(struct intel_atomic_state *state, struct intel_crtc *crtc) { struct drm_i915_private *dev_priv = to_i915(state->base.dev); - const struct intel_crtc_state *new_crtc_state = - intel_atomic_get_new_crtc_state(state, crtc); + const struct intel_crtc_state *old_crtc_state = + intel_atomic_get_old_crtc_state(state, crtc); + struct intel_crtc *pipe_crtc; /* * We need to disable pipe CRC before disabling the pipe, * or we race against vblank off. */ - intel_crtc_disable_pipe_crc(crtc); + for_each_intel_crtc_in_pipe_mask(&dev_priv->drm, pipe_crtc, + intel_crtc_joined_pipe_mask(old_crtc_state)) + intel_crtc_disable_pipe_crc(pipe_crtc); dev_priv->display.funcs.display->crtc_disable(state, crtc); - crtc->active = false; - intel_fbc_disable(crtc); - if (!new_crtc_state->hw.active) - intel_initial_watermarks(state, crtc); + for_each_intel_crtc_in_pipe_mask(&dev_priv->drm, pipe_crtc, + intel_crtc_joined_pipe_mask(old_crtc_state)) { + const struct intel_crtc_state *new_pipe_crtc_state = + intel_atomic_get_new_crtc_state(state, pipe_crtc); + + pipe_crtc->active = false; + intel_fbc_disable(pipe_crtc); + + if (!new_pipe_crtc_state->hw.active) + intel_initial_watermarks(state, pipe_crtc); + } } static void intel_commit_modeset_disables(struct intel_atomic_state *state) @@ -6923,19 +6932,21 @@ static void intel_commit_modeset_disables(struct intel_atomic_state *state) if ((disable_pipes & BIT(crtc->pipe)) == 0) continue; + if (intel_crtc_is_bigjoiner_slave(old_crtc_state)) + continue; + /* In case of Transcoder port Sync master slave CRTCs can be * assigned in any order and we need to make sure that * slave CRTCs are disabled first and then master CRTC since * Slave vblanks are masked till Master Vblanks. */ if (!is_trans_port_sync_slave(old_crtc_state) && - !intel_dp_mst_is_slave_trans(old_crtc_state) && - !intel_crtc_is_bigjoiner_slave(old_crtc_state)) + !intel_dp_mst_is_slave_trans(old_crtc_state)) continue; intel_old_crtc_state_disables(state, crtc); - disable_pipes &= ~BIT(crtc->pipe); + disable_pipes &= ~intel_crtc_joined_pipe_mask(old_crtc_state); } /* Disable everything else left on */ @@ -6943,9 +6954,12 @@ static void intel_commit_modeset_disables(struct intel_atomic_state *state) if ((disable_pipes & BIT(crtc->pipe)) == 0) continue; + if (intel_crtc_is_bigjoiner_slave(old_crtc_state)) + continue; + intel_old_crtc_state_disables(state, crtc); - disable_pipes &= ~BIT(crtc->pipe); + disable_pipes &= ~intel_crtc_joined_pipe_mask(old_crtc_state); } drm_WARN_ON(&i915->drm, disable_pipes);
