From 674dedc87a860f7aea41d5a37d8fd842e196dfdd Mon Sep 17 00:00:00 2001 From: Topi Pohjolainen Date: Tue, 26 Mar 2013 15:14:20 +0200 Subject: [PATCH] dri: propagate extra dma_buf import attributes to the drivers v2: do not break ABI, but instead introduce new entry point for dma buffers and bump up the dri-interface version to eight v3 (Chad): allow the hook to specify an error originating from the driver. For now only unsupported format is considered. I thought about rejecting the hints also as they are addressing only YUV sampling which is not supported at the moment but then thought against it as the spec is not saying one way or the other. v4 (Eric, Chad): restrict to rgb formatted only v5: rebased on top of i915/i965 split v6 (Chad): document using full extension name Signed-off-by: Topi Pohjolainen Reviewed-by: Chad Versace --- include/GL/internal/dri_interface.h | 39 +++++++++++++++++- src/mesa/drivers/dri/i965/intel_regions.h | 7 ++++ src/mesa/drivers/dri/i965/intel_screen.c | 48 ++++++++++++++++++++++- 3 files changed, 91 insertions(+), 3 deletions(-) diff --git a/include/GL/internal/dri_interface.h b/include/GL/internal/dri_interface.h index 5c99d5596df..be31bb874b9 100644 --- a/include/GL/internal/dri_interface.h +++ b/include/GL/internal/dri_interface.h @@ -940,7 +940,7 @@ struct __DRIdri2ExtensionRec { * extensions. */ #define __DRI_IMAGE "DRI_IMAGE" -#define __DRI_IMAGE_VERSION 7 +#define __DRI_IMAGE_VERSION 8 /** * These formats correspond to the similarly named MESA_FORMAT_* @@ -1027,6 +1027,25 @@ struct __DRIdri2ExtensionRec { * 7+.
