Description Andreas Boll 2014-02-17 18:52:08 UTC
This bug is for tracking all the outstanding HyperZ issues on r600g and radeonsi.
Comment 1 funkydude 2014-02-22 15:40:19 UTC
Is there some form of attack plan for fixing these issues?
Comment 2 commiethebeastie 2014-02-23 13:31:17 UTC
How to set R600_HYPERZ=1 by default in Unity 7?
Comment 3 Marek Olšák 2014-02-23 14:03:50 UTC
The variable is called R600_DEBUG. Type: "R600_DEBUG=help glxgears"
Comment 4 Alex Deucher 2014-02-24 14:40:02 UTC

> Is there some form of attack plan for fixing these issues?

We need to figure out what combination(s) of GL state cause a problem with hyperZ, then either disable hyperZ in those cases, or adjust the hyperZ-specific state to avoid the hang in those specific cases.  Ideally we'd be able to find a small test case where we can reproduce the issue(s).
Comment 5 funkydude 2014-02-24 16:01:34 UTC
Is that something us users can help with? :p
Comment 6 commiethebeastie 2014-02-27 09:12:59 UTC
No any regressions with R600_DEBUG=hyperz on Asus DirectCU RHD6850.

Tested on Serious Sam III, Unigine, Portal 2, Compiz, Lightsmark 2008, Europe Universalis IV, Fallout New Vegas :) 

Are you need in more info?
Comment 7 commiethebeastie 2014-02-27 09:17:35 UTC
echo $R600_DEBUG
Comment 8 Grigori Goronzy 2014-02-27 12:20:58 UTC
Please check the bugs this one depends on. There are various well known applications and games that have problems (GPU hangs and/or image corruption) with HyperZ enabled. The geometry shader refactoring also introduced a regression.

Comment 13 commiethebeastie 2014-02-27 16:38:59 UTC
Also it hangs without hyperz :( (rhd3200)
Comment 14 funkydude 2014-02-27 17:12:32 UTC
I honestly don't know why you thought spamming this ticket (and the people CC'd to it) was a good idea with something that has nothing to do with the issue. Maybe someone can purge it?

Please make a separate ticket for issues.
Comment 15 Marek Olšák 2014-02-27 23:12:32 UTC
Please file separate bug reports for your issues. This is only a meta bug aggregating all HyperZ bugs.
Comment 16 David Heidelberg (okias) 2014-05-09 21:15:00 UTC
Could be done some kind of white-list?

For example it seems work very well on 6550D APU and without HyperZ performance really suffer even for old games. There is not much reasons to not enable it here. I browsed bug reports and non of them is APU related, so maybe give a shot for these?

I did test on 3.12.18 kernel, with DPM on, GL_VERSION: 3.0 Mesa 10.3.0-devel (git-23e9f06). Tested SW: KWin with composite, Counter Strike 1.6 (improved performance), 0AD (also improved speed), glmark2 2014.03 (515 points -> 717).

Thank you

Did you test the games referenced in those bug reports?
Comment 18 David Heidelberg (okias) 2014-05-17 14:13:07 UTC
At this moment only Unigine Sanctuary (it work as expected), now downloading Unigine Heaven.

Some of games I'm not able to test, but I tested piglit quick set and no regression showed up.
Comment 19 David Heidelberg (okias) 2014-10-12 08:17:48 UTC
After Marek fixed some HyperZ issues, older issues are FIXED or waiting to confirm. As usual, I tested it and didn't noticed any problems.

Is there possibility enable HyperZ soon as possible, to be able get enough feedback until 10.4 release?
Comment 20 Andreas Boll 2014-10-24 07:34:25 UTC
Hyper-Z has been re-enabled by default with

commit 14bdcc6ff98664552216acfdb7e35d0b128003ef
Author: Andreas Boll <andreas.boll.dev@gmail.com>
Date:   Thu Oct 23 14:52:55 2014 +0200

    radeon: enable Hyper-Z on r600g and radeonsi by default
    This reverts commit 01e637114914453451becc0dc8afe60faff48d84.
    Since then many Hyper-Z issues have been fixed or worked around.
    Enable Hyper-Z by default so that we get enough feedback for the upcoming
    mesa 10.4 release.
    If you have issues with Hyper-Z try to disable Hyper-Z using the enviroment
    variable R600_DEBUG=nohyperz and please report the issue on the bugtracker.
