Subject: dri_inteface: add define for checking presence of drm.h
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0b932284f2294a1dc02004d3b6ef6dfb633bc4bb;p=mesa.git

dri_inteface: add define for checking presence of drm.h

__NOT_HAVE_DRM_H is a like a feature, defined by default on specific platforms
and allows to be defined externally as well.

__NOT_HAVE_DRM_H should only be used by xserver and mesa swrast_dri drivers
