From: Maarten Lankhorst Date: Fri, 5 Oct 2018 09:52:44 +0000 (+0200) Subject: drm/i915: Make shared dpll functions take crtc_state, v3. X-Git-Tag: v5.4-rc1~1388^2~28^2~579 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=65c307fd08dd6cc7771220ee0238a152db552d97;p=platform%2Fkernel%2Flinux-rpi.git drm/i915: Make shared dpll functions take crtc_state, v3. Do not rely on crtc->config any more. Remove the assertion from ibx_pch_dpll_disable, because we the dpll state tracking should already handle this case correctly. Changes since v1: - Fixup accidental early return in intel_prepare_shared_dpll, oops! Changes since v2: - Don't use the freed crtc_state in intel_crtc_disable_noatomic() Signed-off-by: Maarten Lankhorst Reviewed-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20181005095244.1324-1-maarten.lankhorst@linux.intel.com --- diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index df5ae1e..2d526fc 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -4758,7 +4758,7 @@ static void ironlake_pch_enable(const struct intel_atomic_state *state, * Note that enable_shared_dpll tries to do the right thing, but * get_shared_dpll unconditionally resets the pll - we need that to have * the right LVDS enable sequence. */ - intel_enable_shared_dpll(crtc); + intel_enable_shared_dpll(crtc_state); /* set transcoder timing, panel must allow it */ assert_panel_unlocked(dev_priv, pipe); @@ -5600,8 +5600,8 @@ static void ironlake_crtc_enable(struct intel_crtc_state *pipe_config, intel_set_cpu_fifo_underrun_reporting(dev_priv, pipe, false); intel_set_pch_fifo_underrun_reporting(dev_priv, pipe, false); - if (intel_crtc->config->has_pch_encoder) - intel_prepare_shared_dpll(intel_crtc); + if (pipe_config->has_pch_encoder) + intel_prepare_shared_dpll(pipe_config); if (intel_crtc_has_dp_encoder(intel_crtc->config)) intel_dp_set_m_n(intel_crtc, M1_N1); @@ -5719,8 +5719,8 @@ static void haswell_crtc_enable(struct intel_crtc_state *pipe_config, intel_encoders_pre_pll_enable(crtc, pipe_config, old_state); - if (intel_crtc->config->shared_dpll) - intel_enable_shared_dpll(intel_crtc); + if (pipe_config->shared_dpll) + intel_enable_shared_dpll(pipe_config); if (INTEL_GEN(dev_priv) >= 11) icl_map_plls_to_ports(crtc, pipe_config, old_state); @@ -6295,7 +6295,7 @@ static void intel_crtc_disable_noatomic(struct drm_crtc *crtc, intel_fbc_disable(intel_crtc); intel_update_watermarks(intel_crtc); - intel_disable_shared_dpll(intel_crtc); + intel_disable_shared_dpll(to_intel_crtc_state(crtc->state)); domains = intel_crtc->enabled_power_domains; for_each_power_domain(domain, domains) @@ -12744,7 +12744,7 @@ static void intel_atomic_commit_tail(struct drm_atomic_state *state) dev_priv->display.crtc_disable(old_intel_crtc_state, state); intel_crtc->active = false; intel_fbc_disable(intel_crtc); - intel_disable_shared_dpll(intel_crtc); + intel_disable_shared_dpll(old_intel_crtc_state); /* * Underruns don't always raise diff --git a/drivers/gpu/drm/i915/intel_dpll_mgr.c b/drivers/gpu/drm/i915/intel_dpll_mgr.c index e6cac92..10e8208 100644 --- a/drivers/gpu/drm/i915/intel_dpll_mgr.c +++ b/drivers/gpu/drm/i915/intel_dpll_mgr.c @@ -131,11 +131,11 @@ void assert_shared_dpll(struct drm_i915_private *dev_priv, * This calls the PLL's prepare hook if it has one and if the PLL is not * already enabled.
