From: Jason Ekstrand Date: Fri, 27 Jun 2014 22:34:53 +0000 (-0700) Subject: mesa: Add GL API support for ARB_copy_image X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=41b6460e08bf878ec3372937f63bef2a7b63c484;p=mesa.git mesa: Add GL API support for ARB_copy_image This adds the API entrypoint, error checking logic, and a driver hook for the ARB_copy_image extension. v2: Fix a typo in ARB_copy_image.xml and add it to the makefile v3: Put ARB_copy_image.xml in the right place alphebetically in the makefile and properly prefix the commit message v4: Fixed some line wrapping and added a check for null v5: Check for incomplete renderbuffers Signed-off-by: Jason Ekstrand Reviewed-by: Juha-Pekka Heikkila Reviewed-by: Neil Roberts v6: Update dispatch_sanity for the addition of CopyImageSubData --- diff --git a/src/mapi/glapi/gen/ARB_copy_image.xml b/src/mapi/glapi/gen/ARB_copy_image.xml new file mode 100644 index 00000000000..2fbd84557a9 --- /dev/null +++ b/src/mapi/glapi/gen/ARB_copy_image.xml @@ -0,0 +1,28 @@ + + + + + + + + + + + + + + + + + + + + + + + + + + + + diff --git a/src/mapi/glapi/gen/Makefile.am b/src/mapi/glapi/gen/Makefile.am index 212731fa404..645def4ef5c 100644 --- a/src/mapi/glapi/gen/Makefile.am +++ b/src/mapi/glapi/gen/Makefile.am @@ -117,6 +117,7 @@ API_XML = \ ARB_compressed_texture_pixel_storage.xml \ ARB_compute_shader.xml \ ARB_copy_buffer.xml \ + ARB_copy_image.xml \ ARB_debug_output.xml \ ARB_depth_buffer_float.xml \ ARB_depth_clamp.xml \ diff --git a/src/mapi/glapi/gen/gl_API.xml b/src/mapi/glapi/gen/gl_API.xml index e011509e538..619717d9e9e 100644 --- a/src/mapi/glapi/gen/gl_API.xml +++ b/src/mapi/glapi/gen/gl_API.xml @@ -8302,7 +8302,7 @@ - + diff --git a/src/mapi/glapi/gen/gl_genexec.py b/src/mapi/glapi/gen/gl_genexec.py index 4609193977d..d479e66da03 100644 --- a/src/mapi/glapi/gen/gl_genexec.py +++ b/src/mapi/glapi/gen/gl_genexec.py @@ -62,6 +62,7 @@ header = """/** #include "main/condrender.h" #include "main/context.h" #include "main/convolve.h" +#include "main/copyimage.h" #include "main/depth.h" #include "main/dlist.h" #include "main/drawpix.h" diff --git a/src/mesa/Makefile.sources b/src/mesa/Makefile.sources index 45c53ca0e0e..d02c174d912 100644 --- a/src/mesa/Makefile.sources +++ b/src/mesa/Makefile.sources @@ -31,6 +31,7 @@ MAIN_FILES = \ $(SRCDIR)main/condrender.c \ $(SRCDIR)main/context.c \ $(SRCDIR)main/convolve.c \ + $(SRCDIR)main/copyimage.c \ $(SRCDIR)main/cpuinfo.c \ $(SRCDIR)main/debug.c \ $(SRCDIR)main/depth.c \ diff --git a/src/mesa/main/copyimage.c b/src/mesa/main/copyimage.c new file mode 100644 index 00000000000..e1110dd7e00 --- /dev/null +++ b/src/mesa/main/copyimage.c @@ -0,0 +1,356 @@ +/* + * Mesa 3-D graphics library + * + * Copyright (C) 2014 Intel Corporation.
