From 10028c5ab107d3765c7fc282b6c45324d1602155 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 30 Nov 2015 10:55:13 -0800 Subject: drm: Create a driver hook for allocating GEM object structs. The CMA helpers had no way for a driver to extend the struct with its own fields. Since the CMA helpers are mostly "Allocate a drm_gem_cma_object, then fill in a few fields", it's hard to write as pure helpers without passing in a driver callback for the allocate step.
