[Mesa-dev] [PATCH 01/10] loader: introduce the loader util lib
Emil Velikov
emil.l.velikov at gmail.com
Sun Jan 12 16:01:03 PST 2014
All the various window system integration layers duplicate roughly the
same code for figuring out device and driver name, pci-id's, etc. Which
is sad. So extract it out into a loader util lib.
Signed-off-by: Rob Clark <robclark at freedesktop.org>
v2 (Emil)
* Separate the introduction of libloader from the code de-duplication.
* Strip out non-pci devices support.
* Add scons + Android build system support.
* Add VISIBILITY_CFLAGS to avoid exporting the loader funcs.
v3 (Emil)
* PIPE_OS_ANDROID is undefined at this scope, use ANDROID
* Make sure we define _EGL_NO_DRM when building only swrast
