Description Mike Lothian 2016-05-22 20:53:28 UTC

Hi

I've been having issues starting the game with high settings at 4k resolution on Tonga, at lower settings I'm seeing graphical glitches https://www.youtube.com/watch?v=ZyKjahCamLQ

If I start the game in low settings and turn up the settings the game freezes up (I've also had the same issues with high settings on DiRT)

I'm running agd5f's drm-next-4.8-wip branch, I've also tried with kernel 4.5 & 4.6

The issue goes away if I'm running llvm-3.8 & Mesa 11.2.2 or running llvm-3.8 with Mesa-git, I can't compile Mesa 11.2.2 with llvm-git

This is a prime system Skylake/Tonga - I don't have any issues starting these games on Skylake or see any graphical glitches (of course the game is very slow with these settings)

I think these are the same issues that were spotted on Phoronix too

Once the apitrace is uploaded I'll post the link

Comment 3 Mike Lothian 2016-05-22 21:08:40 UTC

To clarify, when the settings are too high, the same starts and plays the intro videos but at the point where the cursor normally appears and the main menu is shown, the screen just remains black. I can switch out of the app but I can't kill the process. The only way to stop it is to restart the machine - the graphics card remains powered

Trace taken with Apitrace 7.1 can be downloaded from https://drive.google.com/file/d/0BySKFkadlRnpOC04aEJCNGNKeVk/view?usp=sharing

Comment 5 Michel Dänzer 2016-05-24 07:01:48 UTC

If you replay the apitrace, does it produce exactly the same visuals and other symptoms as when playing the game itself? I get what looks like essentially random vertices all over the place, which might indicate that something went wrong when capturing the apitrace. Maybe try setting the environment variable MESA_EXTENSION_OVERRIDE="-GL_ARB_buffer_storage" for capturing the apitrace.

Comment 6 Mike Lothian 2016-05-24 23:41:52 UTC

No it doesn't play correctly when I try and reply it:

Comment 7 Mike Lothian 2016-05-24 23:43:52 UTC

I tried re-recording with MESA_EXTENSION_OVERRIDE="-GL_ARB_buffer_storage" but where the main menu would normally appear, the screen turned white with small coloured dots

Would you like me to try and record with i965 and replay on radeonsi to see if the same issue still happens?

Comment 8 Jan Ziak (http://atom-symbol.net) 2016-05-30 09:43:34 UTC

R9 390:

- The game has no problems starting at 1080p resolution with any in-game preset setting

- There are graphical glitches (flags and mirrors)

The rendering glitches seem to be purely a LLVM_3.9-related issue.

Comment 9 Vedran Miletić 2016-05-30 18:47:53 UTC

Discussed on #radeon, couldn't reproduce on Tonga:

Hi, I have the same problem on SI (verde). Should I open new raport?

Problem has started since llvm-r266378

Patch of the revert of D19091

This patch is the reversion of D19091

Which fixes the issue for me - the graphical glitches are gone

Matt, any ideas?

Trimmed R600_DEBUG=vs,ps output & shader GL calls with LLVM r273782

I could not record an apitrace (game hangs before getting to the main menu, possibly performance related), but I was able to dump the shaders and narrow down (some of) the affected ones.

The game uses two passes to render the flags and banners: The first pass (possibly a z prepass?) uses pipeline=20 in the attached logs (vertex shader=73, program=74; fragment shader=89, program=90).

The second pass is depth-tested against the results of the first, but uses different shaders - pipeline=105 (vertex shader=383 program=384; fragment shader=381, program=382).

With LLVM r266378 reverted, the results of the two passes line up, with current LLVM they do not causing the z-fighting visible in the video linked in the bug description. Even when disabling the depth test in the second pass, there are still visible parts of "white" background so this is a) most likely an issue with one of the vertex shaders and b) not just a depth precision issue. You can also see this by looking closely at the flags in the video - the while (holes punched by the z-prepass) and textured parts sway differently.

Since the game compiles an enormous amount of shaders on startup, the full  R600_DEBUG=cs,vs,tcs,tes,gs,ps output is quite large - I have attached a trimmed output that only contains the two vertex/fragment shader pairs used for the banners. The full logs are available at:
 http://constexpr.org/tmp/bioshockinfinite-bad.log (20 MiB)
 http://constexpr.org/tmp/bioshockinfinite-good.log (21 MiB)

Comment 16 Mike Lothian 2016-06-30 15:24:51 UTC

The revert nolong applied cleanly since "CodeGen: Use MachineInstr& in TargetInstrInfo, NFC"

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@274189 91177308-0d34-0410-b5e6-96231b3b80d8

Is there any chance you could revert the original change until a fix can be found for the regression

Comment 17 Matt Arsenault 2016-07-01 00:11:59 UTC

This is going to be a pre-existing bug. Can you narrow it down to a particular shader? I'm not familiar with debugging graphics

D21961 which isn't currently in llvm master fixes the issue for me

I have a feeling https://reviews.llvm.org/D22032 fixed the issue where I could run the game at Ultra settings, certainly one of the changes in the last two days has fixed it for me
