[PATCH 4/7] lib: Add gem_userptr helpers
Tiago Vignatti
tiago.vignatti at intel.com
Wed Aug 12 16:29:17 PDT 2015
This patch moves userptr definitions and helpers implementation that were
locally in gem_userptr_benchmark and gem_userptr_blits to the library, so other
tests can make use of them as well. There's no functional changes.
