From a81ef14228c6fe2893527b7b5f12855c90db3f8e Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Wed, 23 Jun 2010 21:36:20 +0800 Subject: st/egl: Build a single EGL driver. This change makes st/egl build a single egl_gallium.so and multiple st_.so and pipe_.so. When a display is initialized, the corresponding pipe driver will be loaded. When a context is created, the corresponding state tracker will be loaded. Unlike DRI drivers, no ABI compatibility is maintained. egl_gallium, pipe drivers and state trackers should always be distributed as a single package. As such, there is only a single src/gallium/targets/egl/ that builds everything for the package. --- src/gallium/targets/egl/Makefile | 75 +++++++-------- src/gallium/targets/egl/SConscript | 6 +- src/gallium/targets/egl/egl.c | 165 ++++++++++++++++++++++++++++----- src/gallium/targets/egl/pipe_i965.c | 1 + src/gallium/targets/egl/pipe_nouveau.c | 1 + src/gallium/targets/egl/pipe_radeon.c | 1 + src/gallium/targets/egl/pipe_swrast.c | 18 ++++ src/gallium/targets/egl/pipe_vmwgfx.c | 1 + 8 files changed, 205 insertions(+), 63 deletions(-) (limited to 'src/gallium/targets/egl') diff --git a/src/gallium/targets/egl/Makefile b/src/gallium/targets/egl/Makefile index 80f9c60559..b9db6bc2c9 100644 --- a/src/gallium/targets/egl/Makefile +++ b/src/gallium/targets/egl/Makefile @@ -2,8 +2,9 @@ # # This is the Makefile for EGL Gallium driver package.
