From 1bf703e4ea5c4f742bc7ba55d01e5afc3f4e11f9 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Fri, 28 Jul 2017 17:30:34 +0200 Subject: [PATCH] dri_interface,egl,gallium: only expose RGBA visuals on Android MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit X/GLX can't handle them. This removes almost 500 GLX visuals that were incorrectly exposed. Add an optional getCapability callback for querying what the loader can do. I'm not splitting this patch, because it's already too small. v2: also add the callback to __DRIimageLoaderExtension Reviewed-by: Nicolai Hähnle Cc: 17.2 --- include/GL/internal/dri_interface.h | 28 +++++++++++++++++++-- src/egl/drivers/dri2/platform_android.c | 18 +++++++++++-- src/gallium/state_trackers/dri/dri_screen.c | 24 +++++++++++++++++- 3 files changed, 65 insertions(+), 5 deletions(-) diff --git a/include/GL/internal/dri_interface.h b/include/GL/internal/dri_interface.h index a8f5af145df..c314a43faad 100644 --- a/include/GL/internal/dri_interface.h +++ b/include/GL/internal/dri_interface.h @@ -967,7 +967,15 @@ struct __DRIbufferRec { }; #define __DRI_DRI2_LOADER "DRI_DRI2Loader" -#define __DRI_DRI2_LOADER_VERSION 3 +#define __DRI_DRI2_LOADER_VERSION 4 + +enum dri_loader_cap { + /* Whether the loader handles RGBA channel ordering correctly.
