From 337ce80bc20903cd001582ab3dbd23019e89f531 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 19 Jun 2019 20:08:40 +0300 Subject: [PATCH] drm/i915: Switch to per-crtc vblank vfuncs MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Switch from the driver-wide vblank vfuncs to the per-crtc ones so that we don't have so many platform specific vfuncs in the driver struct. We still need to do something about the rest fo the irq vfuncs... v2: s/INTEL_GEN>=3/IS_GEN3/ Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20190619170842.20579-3-ville.syrjala@linux.intel.com Reviewed-by: Chris Wilson --- drivers/gpu/drm/i915/display/intel_display.c | 104 ++++++++++++++++--- drivers/gpu/drm/i915/i915_irq.c | 93 +++++++---------- drivers/gpu/drm/i915/i915_irq.h | 14 +++ 3 files changed, 143 insertions(+), 68 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_display.c b/drivers/gpu/drm/i915/display/intel_display.c index 5f30f348b0c0b..e55bd75528c17 100644 --- a/drivers/gpu/drm/i915/display/intel_display.c +++ b/drivers/gpu/drm/i915/display/intel_display.c @@ -13567,7 +13567,7 @@ u32 intel_crtc_get_vblank_counter(struct intel_crtc *crtc) if (!vblank->max_vblank_count) return (u32)drm_crtc_accurate_vblank_count(&crtc->base);
