First of all, Thanks.
I suppose the egl-drm will use /usr/lib/dri/* drivers, what does the
pipe_swrast.so for? and why we can't use swrast with DRM?
It seems drmdpy->event_handler->new_drm_screen at
gallium/state_trackers/egl/drm/native_drm.c is just for it.
By the way, configure.ac:
if test "$mesa_driver" = dri; then
# build egl_dri2 when xcb-dri2 is available
PKG_CHECK_MODULES([XCB_DRI2], [x11-xcb xcb-dri2 xcb-xfixes],
[have_xcb_dri2=yes],[have_xcb_dri2=no])
Would there need some kind of warnings about package missing or just don't
check them up to users?
Best Regards,
Arthur
