[Intel-gfx] [PATCH v4 4/5] drm: Add decoding of i915 ioctls
Patrik Jakobsson
patrik.jakobsson at linux.intel.com
Mon Aug 24 05:42:49 PDT 2015
First batch of i915 drm ioctls
* Makefile.am: Add compilation of drm_i915.c.
* defs.h: Add extern i915 declarations
* drm.c (drm_ioctl): Dispatch i915 ioctls.
* drm_i915.c: New file.
* xlat/drm_i915_getparams.in: New file.
* xlat/drm_i915_setparams.in: New file.
* xlat/drm_i915_ioctls.in: New file.
