From 28a62277e06f93729d0340d9659153dcfbdbe16d Mon Sep 17 00:00:00 2001 From: Ben Gamari Date: Tue, 17 Feb 2009 20:08:49 -0500 Subject: drm: Convert proc files to seq_file and introduce debugfs The old mechanism to formatting proc files is extremely ugly. The seq_file API was designed specifically for cases like this and greatly simplifies the process. Also, most of the files in /proc really don't belong there. This patch introduces the infrastructure for putting these into debugfs and exposes all of the proc files in debugfs as well.
