From 276199e6be6a4058e74828728eb25179b1461978 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jos=C3=A9=20Roberto=20de=20Souza?= Date: Thu, 11 Jul 2019 10:31:01 -0700 Subject: [PATCH] drm/i915/tgl: rename TRANSCODER_EDP_VDSC to use on transcoder A MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On TGL the special EDP transcoder is gone and it should be handled by transcoder A. v2 (Lucas): - Reuse POWER_DOMAIN_TRANSCODER_EDP_VDSC (suggested by Ville) - Use crtc->dev since new_crtc_state->state may be NULL on atomic commit (suggested by Maarten) v3 (Lucas): - Rename power domain so it's clear it can also be used for transcoder A in TGL (requested by José and Manasi) Cc: Imre Deak Signed-off-by: José Roberto de Souza Signed-off-by: Lucas De Marchi Acked-by: José Roberto de Souza Reviewed-by: Manasi Navare Link: https://patchwork.freedesktop.org/patch/msgid/20190711173115.28296-8-lucas.demarchi@intel.com --- drivers/gpu/drm/i915/display/intel_display_power.c | 6 +++--- drivers/gpu/drm/i915/display/intel_display_power.h | 3 ++- drivers/gpu/drm/i915/display/intel_vdsc.c | 14 ++++++++++---- 3 files changed, 15 insertions(+), 8 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_display_power.c b/drivers/gpu/drm/i915/display/intel_display_power.c index 7e22a2704843..6a5e0d0724cb 100644 --- a/drivers/gpu/drm/i915/display/intel_display_power.c +++ b/drivers/gpu/drm/i915/display/intel_display_power.c @@ -48,8 +48,8 @@ intel_display_power_domain_str(enum intel_display_power_domain domain) return "TRANSCODER_C"; case POWER_DOMAIN_TRANSCODER_EDP: return "TRANSCODER_EDP"; - case POWER_DOMAIN_TRANSCODER_EDP_VDSC: - return "TRANSCODER_EDP_VDSC"; + case POWER_DOMAIN_TRANSCODER_VDSC_PW2: + return "TRANSCODER_VDSC_PW2"; case POWER_DOMAIN_TRANSCODER_DSI_A: return "TRANSCODER_DSI_A"; case POWER_DOMAIN_TRANSCODER_DSI_C: @@ -2450,7 +2450,7 @@ void intel_display_power_put(struct drm_i915_private *dev_priv, */ #define ICL_PW_2_POWER_DOMAINS ( \ ICL_PW_3_POWER_DOMAINS | \ - BIT_ULL(POWER_DOMAIN_TRANSCODER_EDP_VDSC) | \ + BIT_ULL(POWER_DOMAIN_TRANSCODER_VDSC_PW2) | \ BIT_ULL(POWER_DOMAIN_INIT)) /* * - KVMR (HW control) diff --git a/drivers/gpu/drm/i915/display/intel_display_power.h b/drivers/gpu/drm/i915/display/intel_display_power.h index 8f43f7051a16..cc6956132ebc 100644 --- a/drivers/gpu/drm/i915/display/intel_display_power.h +++ b/drivers/gpu/drm/i915/display/intel_display_power.h @@ -25,7 +25,8 @@ enum intel_display_power_domain { POWER_DOMAIN_TRANSCODER_B, POWER_DOMAIN_TRANSCODER_C, POWER_DOMAIN_TRANSCODER_EDP, - POWER_DOMAIN_TRANSCODER_EDP_VDSC, + /* VDSC/joining for TRANSCODER_EDP (ICL) or TRANSCODER_A (TGL) */ + POWER_DOMAIN_TRANSCODER_VDSC_PW2, POWER_DOMAIN_TRANSCODER_DSI_A, POWER_DOMAIN_TRANSCODER_DSI_C, POWER_DOMAIN_PORT_DDI_A_LANES, diff --git a/drivers/gpu/drm/i915/display/intel_vdsc.c b/drivers/gpu/drm/i915/display/intel_vdsc.c index ffec807b8960..4ab19c432ef5 100644 --- a/drivers/gpu/drm/i915/display/intel_vdsc.c +++ b/drivers/gpu/drm/i915/display/intel_vdsc.c @@ -459,17 +459,23 @@ int intel_dp_compute_dsc_params(struct intel_dp *intel_dp, enum intel_display_power_domain intel_dsc_power_domain(const struct intel_crtc_state *crtc_state) { + struct drm_i915_private *i915 = to_i915(crtc_state->base.crtc->dev); enum transcoder cpu_transcoder = crtc_state->cpu_transcoder; /* - * On ICL VDSC/joining for eDP transcoder uses a separate power well PW2 - * This requires POWER_DOMAIN_TRANSCODER_EDP_VDSC power domain. + * On ICL VDSC/joining for eDP transcoder uses a separate power well, + * PW2.
