Description Christoph Haag 2014-02-12 15:20:43 UTC

The kernel people at https://bugzilla.kernel.org/show_bug.cgi?id=70411 told me this needs to be fixed in mesa, so here it is.

The interesting part:

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wimbledon XT [Radeon HD 7970M]

Latest mesa git, but has probably been happening since HyperZ was enabled by default.

dmesg is attached there: https://bugzilla.kernel.org/attachment.cgi?id=125651

It's reproducible every time so I can later get more detail. For now there's the dmesg: Starting the game and showing some intro works, but shortly before displaying the menu X freezes for a few seconds and after it is usable again, I see the stuff starting at 82688.801309 in dmesg.

HyperZ seems to work fine for everything else I have tried so far. It only happens in the Distance Alpha that's only (officially) available to kickstarter backers.

It's crashing again with

0x7f76ed4687c0: i32 = ExternalSymbol'__muldi3'

For some reason the output seems to be doubled in my log.

I hope it's not a problem that llvm was built from a newer revision than clang.

Sorry to whoever got mails now, didn't mean to post this here.

Is this fixed with current Mesa git?

If not, could you please make and upload a trace file using apitrace:

Thanks.

Comment 4 Christoph Haag 2014-09-01 21:04:35 UTC

Yes, seems to work now after a few short tests. No hangs.

Thanks!

Comment 5 Marek Olšák 2014-09-01 21:29:28 UTC

Did you set this environment variable before testing?

R600_DEBUG=hyperz

There are times when I don't know what I'm doing but this time I used this in steam:

DRI_PRIME=1 GALLIUM_HUD="fps,VRAM-usage+GTT-usage" R600_DEBUG=hyperz %command%

Ok, that looks good. Thanks.
