<pre>I am still unable to get the radeonsi driver working with my Radeon HD 7970.
<a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED NOTOURBUG - X 1.16.1 RC 1 segfaults and reports "XXX fail to create fbo" with Radeon HD 7970."
href="show_bug.cgi?id=84186">Bug 84186</a> was my previous attempt.
Right now I have installed:
kernel from Dave Airlie's drm-next, at commit 4e0cd68 (December 13 2014)
libgl1-mesa-glx 10.3.2-1
xserver-xorg-core 2:1.16.2.901-1
xserver-xorg-video-radeon 1:7.5.0-1
Apart from the kernel, the rest are Debian (jessie) packages.
With this configuration, X starts, but the display is a mess of grey static.
Through the static I can discern a large square which is apparently a mouse
cursor (moves when I move my mouse).
My syslog contains many complaints from the radeon driver which look like:
Dec 26 12:41:57 kano kernel: radeon 0000:01:00.0: ring 0 stalled for more than
10004msec
Dec 26 12:41:57 kano kernel: radeon 0000:01:00.0: GPU lockup (current fence id
0x0000000000000001 last fence id 0x0000000000000051 on ring 0)
Dec 26 12:41:58 kano kernel: [drm:si_gpu_check_soft_reset] MC busy: 0x00000548,
clearing.</pre>
