This bug is for tracking all the outstanding HyperZ issues on r600g and radeonsi.
Is there some form of attack plan for fixing these issues?
How to set R600_HYPERZ=1 by default in Unity 7?
The variable is called R600_DEBUG. Type: "R600_DEBUG=help glxgears"

> 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).
Is that something us users can help with? :p
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?
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.

Also it hangs without hyperz :( (rhd3200)
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.
Please file separate bug reports for your issues. This is only a meta bug aggregating all HyperZ bugs.
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).

Did you test the games referenced in those bug reports?
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.
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?
Hyper-Z has been re-enabled by default with

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.
