From 97b447ee480a09a744094562da36b019a3eeb10f Mon Sep 17 00:00:00 2001 From: Kyle Brenneman Date: Wed, 4 Jan 2017 11:31:58 -0700 Subject: [PATCH 1/2] EGL: Implement the libglvnd interface for EGL (v2) Added separate --enable-libglvnd-glx and --enable-libglvnd-egl configure options to enable libglvnd for GLX and EGL. The existing --enable-libglvnd option will now enable both EGL and GLX. The new interface mostly just sits on top of the existing library. The only change to the existing EGL code is to split the client extension string into platform extensions and everything else. On non-glvnd builds, eglQueryString will just concatenate the two strings. The EGL dispatch stubs are all generated. The script is based on the one used to generate entrypoints in libglvnd itself. v2: Rebased against master. Reworked the EGL makefile to use separate libtool targets instead of an automake substitution "lib@EGL_LIB@_la_*" in the variable names. Using the substitution broke automake's dependency tracking for "make dist". Made the EGL code generation scripts work with Python 2 or 3. Change gen_egl_dispatch.py to use argparse for the command line arguments. Assorted formatting and style cleanup in the Python scripts. --- configure.ac | 154 ++- src/egl/Makefile.am | 97 +- src/egl/generate/egl.xml | 2412 ++++++++++++++++++++++++++++++++++ src/egl/generate/eglFunctionList.py | 197 +++ src/egl/generate/egl_other.xml | 47 + src/egl/generate/genCommon.py | 223 ++++ src/egl/generate/gen_egl_dispatch.py | 250 ++++ src/egl/main/50_mesa.json | 6 + src/egl/main/eglapi.c | 6 +- src/egl/main/egldispatchstubs.c | 110 ++ src/egl/main/egldispatchstubs.h | 26 + src/egl/main/eglglobals.c | 47 +- src/egl/main/eglglobals.h | 13 +- src/egl/main/eglglvnd.c | 82 ++ 14 files changed, 3576 insertions(+), 94 deletions(-) create mode 100755 src/egl/generate/egl.xml create mode 100644 src/egl/generate/eglFunctionList.py create mode 100644 src/egl/generate/egl_other.xml create mode 100644 src/egl/generate/genCommon.py create mode 100755 src/egl/generate/gen_egl_dispatch.py create mode 100644 src/egl/main/50_mesa.json create mode 100644 src/egl/main/egldispatchstubs.c create mode 100644 src/egl/main/egldispatchstubs.h create mode 100644 src/egl/main/eglglvnd.c diff --git a/configure.ac b/configure.ac index de8af874ec..839b25c057 100644 --- a/configure.ac +++ b/configure.ac @@ -528,8 +528,6 @@ else DEFINES="$DEFINES -DNDEBUG" fi -DEFAULT_GL_LIB_NAME=GL - dnl dnl Check if linker supports -Bsymbolic dnl @@ -627,23 +625,6 @@ esac AM_CONDITIONAL(HAVE_COMPAT_SYMLINKS, test "x$HAVE_COMPAT_SYMLINKS" = xyes) -DEFAULT_GL_LIB_NAME=GL - -dnl -dnl Libglvnd configuration -dnl -AC_ARG_ENABLE([libglvnd], - [AS_HELP_STRING([--enable-libglvnd], - [Build for libglvnd @<:@default=disabled@:>@])], - [enable_libglvnd="$enableval"], - [enable_libglvnd=no]) -AM_CONDITIONAL(USE_LIBGLVND_GLX, test "x$enable_libglvnd" = xyes) -#AM_COND_IF([USE_LIBGLVND_GLX], [DEFINES="${DEFINES} -DUSE_LIBGLVND_GLX=1"]) -if test "x$enable_libglvnd" = xyes ;
