From 73263cb6e2fe77681e872f94999458db27d8d7bc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 31 Oct 2019 18:56:47 +0200 Subject: [PATCH] drm/i915: Expose alpha formats on VLV/CHV primary planes MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently we expose VLV/CHV alpha blending only on the sprite planes, but the primary planes can do it as well. Let's flip it on. v2: Rebase due to fp16 landing Signed-off-by: Ville Syrjälä Reviewed-by: Uma Shankar Link: https://patchwork.freedesktop.org/patch/msgid/20191031165652.10868-3-ville.syrjala@linux.intel.com --- drivers/gpu/drm/i915/display/intel_display.c | 62 +++++++++++++++++++- drivers/gpu/drm/i915/i915_reg.h | 1 + 2 files changed, 60 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_display.c b/drivers/gpu/drm/i915/display/intel_display.c index c689cb5f94d3..983649c483a1 100644 --- a/drivers/gpu/drm/i915/display/intel_display.c +++ b/drivers/gpu/drm/i915/display/intel_display.c @@ -111,6 +111,21 @@ static const u32 i965_primary_formats[] = { DRM_FORMAT_XBGR16161616F, };
