From 4ce4728b5113245c731ac3baef36dce0482cce0c Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 1 Oct 2014 09:17:12 -0400 Subject: [PATCH] drm/radeon: add new callback for info ioctl register accessor MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This adds a callback for each asic family to determine what registers are allowed to be read back via the info ioctl. The idea here is to allow usermode to query things like GPU status registers or GPU harvest registers for profiling and determining the gfx config.
