From 7b06894b9b902f540b23e5c235570b224d63ec5e Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Wed, 1 Dec 2021 15:57:03 +0200 Subject: [PATCH] drm/i915/display: add intel_crtc_wait_for_next_vblank() and use it MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit intel_wait_for_vblank() goes through a pipe to crtc lookup, while in most cases we already have the crtc available. Avoid the extra lookups by adding an intel_crtc based helper. v2: - Add intel_crtc_wait_for_next_vblank() helper (Ville) Signed-off-by: Jani Nikula Reviewed-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/90cfbd8c3e79a742b0ee9e3ae75493acb0785dbb.1638366969.git.jani.nikula@intel.com --- drivers/gpu/drm/i915/display/intel_crt.c | 4 +-- drivers/gpu/drm/i915/display/intel_display.c | 32 +++++++++++----------- drivers/gpu/drm/i915/display/intel_display_types.h | 12 ++++++-- drivers/gpu/drm/i915/display/intel_dp.c | 2 +- drivers/gpu/drm/i915/display/intel_sdvo.c | 2 +- drivers/gpu/drm/i915/display/intel_tv.c | 7 ++--- 6 files changed, 32 insertions(+), 27 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_crt.c b/drivers/gpu/drm/i915/display/intel_crt.c index f0f2857..42533e6 100644 --- a/drivers/gpu/drm/i915/display/intel_crt.c +++ b/drivers/gpu/drm/i915/display/intel_crt.c @@ -321,8 +321,8 @@ static void hsw_enable_crt(struct intel_atomic_state *state, intel_crt_set_dpms(encoder, crtc_state, DRM_MODE_DPMS_ON);
