The gauntlet continues... After solving bug 79325, Steam now starts, but when I try to resize any Steam windows, Xorg freezes: it does not react to keyboard input (VT switching or num lock) and killing Steam doesn't unlock it. But the mouse cursor still responds to mouse movements.

There is nothing in Xorg logs after the freeze. 

xorg-server 1.15.1
linux 3.15-rc8
linux-firmware a4f3bc03f1e7b1f25cc52328981c2a35871e55a1 (with PITCAIRN_mc2.bin)
xf86-video-ati 7.3.0
Tried ati-dri/mesa versions 10.2.0rc5 as well as 10.1.3
Tried glamor-egl git a4fbc7732a1e56de385f50b778aafbdd186e015c as well as 0.6.0 (patched with cccfea4454949e3e376be42bb230603848997195 per bug 79325)

gdb dump at the time of freeze:

[mi] These backtraces from mieqEnqueue may point to a culprit higher up the stack.
[mi] mieq is *NOT* the cause.  It is a victim.

Comment 5 Michel Dänzer 2014-06-09 07:30:35 UTC
I can't reproduce this with glamor from xserver Git, can you try that?

If not, or if it still happens with that, please get a backtrace with gdb, and make sure /usr/lib/xorg/modules/dri/radeonsi_dri.so and /usr/lib/xorg/modules/extensions/libglx.so have debugging symbols.

Yeah, still crashes with Glamor as of git 081a537.

Attached the gdb backtrace (both "bt" and "bt full" in this file). I also rebuilt mesa with debug symbols. I'm using kernel 3.14.4 this time.

I figured out that the "mieqEnqueue" backtraces appear when I move my mouse after the X server freezes.

That's the standalone glamor tree. I mean glamor from the current xserver Git tree.

Anyway, I think the attached backtrace can only happen if Steam uses GLX indirect rendering (current versions of Steam present a warning dialog on startup when that's the case). You can try starting Steam with LIBGL_DEBUG=verbose to see why it's not getting direct rendering.

Can/should I build glamor separately or should just build the whole xorg-server from git?

Yeah, I'm aware there are some ABI issues on Arch Linux with Steam's bundled libgcc_s.so.

You're right, it no longer crashes when building xorg-server 1.15.99.903 with --enable-glamor. I do see severe graphics glitches during resizing, but they disappear quickly after and it's not clear whose fault this is.

Is standalone glamor officialy deprecated with xorg-server 1.16?

Are you going to do anything about users of 1.15 or can indirect GLX be safely neglected? :)

You can probably avoid the issues by moving away the bundled libraries.


(In reply to comment #9)
> Is standalone glamor officialy deprecated with xorg-server 1.16?

There's no reason to use glamor from the standalone tree with a version of xserver which includes glamor.


> Are you going to do anything about users of 1.15

There are plans for backporting the glamor changes from xserver to the standalone tree, but the details are still being worked out.


> or can indirect GLX be safely neglected? :)

GLX indirect rendering is never desirable for local clients.
