[Mesa-dev] How to use pipe_swrast.so for rendering?

[Arthur Zhu]

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
