From c591b1e59454db2e8854e36852e0d413ce38b2f2 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Tapani=20P=C3=A4lli?= Date: Tue, 31 Oct 2017 10:56:28 +0200 Subject: [PATCH] i965: expose SRGB visuals and turn on EGL_KHR_gl_colorspace MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Patch exposes sRGB visuals and adds DRI integer query support for __DRI2_RENDERER_HAS_FRAMEBUFFER_SRGB. Further changes make sure that we mark if the app explicitly wanted sRGB and for these framebuffers we don't turn sRGB off in intel_gles3_srgb_workaround. This way we keep compatibility for existing applications relying on default sRGB and ony add more visual support. With this change, following dEQP tests start to pass: dEQP-EGL.functional.wide_color.window_8888_colorspace_srgb dEQP-EGL.functional.wide_color.pbuffer_8888_colorspace_srgb v2: some code cleanup (Emil Velikov) update num_formats correctly (reported by deveee@gmail.com) v3: cleanup, remove redundant is_srgb rename explicit_srgb as 'need_srgb' to follow style better Signed-off-by: Tapani Pälli Reviewed-by: Emil Velikov (v2) Reviewed-by: Kenneth Graunke Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=102264 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=102354 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=102503 --- src/mesa/drivers/dri/i965/brw_context.c | 16 ++++++++++------ src/mesa/drivers/dri/i965/intel_fbo.h | 5 +++++ src/mesa/drivers/dri/i965/intel_screen.c | 12 +++++++++++- 3 files changed, 26 insertions(+), 7 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_context.c b/src/mesa/drivers/dri/i965/brw_context.c index 0ebd4329935..19d5a2e3503 100644 --- a/src/mesa/drivers/dri/i965/brw_context.c +++ b/src/mesa/drivers/dri/i965/brw_context.c @@ -1168,8 +1168,8 @@ intelUnbindContext(__DRIcontext * driContextPriv) * * Unfortunately, renderbuffer setup happens before a context is created.
