From 31ae71fca7f91101613fac9deb8e858e1319b4f5 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Wed, 9 Mar 2016 10:35:45 +0100 Subject: [PATCH] drm/i915: Nuke fbc members from intel_crtc->atomic, v4. Whenever there's an update to the primary plane, fbc_pre_update and fbc_post_update are called. Kill off intel_crtc->atomic.update_fbc and now that intel_crtc->atomic is empty, kill it off too. Changes since v1: - Add a intel_fbc_supports_rotation helper. Changes since v2: - Remove intel_fbc_supports_rotation_helper. - Remove unrelated changes. Changes since v3: - Rebase Signed-off-by: Maarten Lankhorst Link: http://patchwork.freedesktop.org/patch/msgid/1457516145-32117-2-git-send-email-maarten.lankhorst@linux.intel.com Reviewed-by: Paulo Zanoni --- drivers/gpu/drm/i915/intel_display.c | 51 +++++++++------------------- drivers/gpu/drm/i915/intel_drv.h | 15 -------- 2 files changed, 16 insertions(+), 50 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 8a834261155b..ed650a4f67b6 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -4673,11 +4673,9 @@ static void intel_post_plane_update(struct intel_crtc_state *old_crtc_state) { struct intel_crtc *crtc = to_intel_crtc(old_crtc_state->base.crtc);
