From 6f646095ec2f5d38a6429dd896cb2d5cbbb776dc Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Mon, 10 Dec 2012 10:46:43 -0600 Subject: drm/cma: add debugfs helpers Add helper to display fb's which can be used directly in drm_info_list: static struct drm_info_list foo_debugfs_list[] = { ... { "fb", drm_fb_cma_debugfs_show, 0 }, }; to display information about CMA fb objects, as well as a drm_gem_cma_describe() which can be used if the driver bothers to keep a list of CMA GEM objects.
