From: Chia-I Wu Date: Wed, 26 Aug 2009 08:39:29 +0000 (+0800) Subject: EGL_i915: Make struct drm_device per display. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=49f245ea6bc2f9b7ee0345ff42cb00aa969cd316;p=mesa.git EGL_i915: Make struct drm_device per display. This is to allow a driver to drive multiple displays.
