[Regression] Radv

[Jhackler]

Quick summary

starting at rpcs3-v0.0.23-14063-a401a192_linux64 all games segfault when loading spu cache or right after building.

Details

rpcs3-v0.0.23-14059-6e9df9e4_linux64 is the newest build that is working on my arch system starting at rpcs3-v0.0.23-14063-a401a192_linux64 all games segfault when loading spu cache or right after building. this results in a soft lock requiring rpcs3 to be killed in the terminal. Log is from draken guard but I confirmed across 8 games. (which is all I own)

Build with regression

v0.0.23-14063-a401a192

[AniLeo]

The extension is in RADV if you're using mesa-git, either way it's detected and if it's not present then it's simply ignored.

Did you test with any other driver to deem it a radv issue?

[kd-11]

I'm unable to reproduce on all 3 drivers on my system. RADV, AMDVLK and llvmpipe. Try one of the other two and see if it crashes.

[Jhackler]

Since arch tends to get the stable mesa drivers pretty fast after they are actually release I don't use mesa git, someone in discord when I found the first version this occurred thought that might be related, and I checked the current non git mesa does not have it. As far as amdvlk I will try it later the fact it is slower and now the default if its installed has kept me from adding it lol.

[kd-11]

There is an environment variable that permanently tells AMDVLK to let RADV be the default.

[AniLeo]

I don't see the cube on latest mesa-git, there's something wrong

mesa-git-22.3.0_devel.159135.802fa57274bb.d41d8cd98f00b204e9800998ecf8427e-1-x86_64.pkg.tar.zst

Just built latest mesa-git and rpcs3-git on Arch

Cleared mesa shader caches and all RPCS3 caches.

Rendering is completely broken. Red Dead Redemption menu looks like this and uses 85% of my GPU.

OpenGL is fine by the way, this only effects RPCS3 Vulkan/RADV

It also happens to me that from the "rpcs3-v0.0.23-14063-a401a192_linux64" version there are problems with vulkan. the previous version "rpcs3-v0.0.23-14059-6e9df9e4_linux64" works fine. check the commits please.

[AniLeo]

There are two different issues here

a) One stability issue on mesa stable b) One graphical issue on mesa-git

For the first one, neither me or kd can reproduce

For the second one:

I tested with an older version of mesa and latest version of RPCS3 and it's working fine Any stable mesa up to this moment doesn't have VK_EXT_attachment_feedback_loop_layout

The regression is not on our side, I have bisected it to be within this range: PASS: mesa-git-22.3.0_devel.158313.d6b61fcf60e2.d41d8cd98f00b204e9800998ecf8427e-1-x86_64.pkg.tar.zst FAIL: mesa-git-22.3.0_devel.159135.802fa57274bb.d41d8cd98f00b204e9800998ecf8427e-1-x86_64.pkg.tar.zst

As such, a ticket needs to be opened in the mesa tracker, if it's still an on-going regression

[kd-11]

Some more details to consider:

• Only mesa-git has the attachment feedback loop layout extension. If this was what was broken, windows and NVIDIA users would also be affected.
• I used mesa-git to add support for the extension. I was able to run the emulator and play some games on it without problems after.

It seems that indeed there is a regression with RADV that needs reporting and some other issue with older mesa-stable. It may report some feature flags for the extension without actually supporting the implementation, though that shouldn't happen in stable branch.

[Jhackler]

Sorry I have not gotten to testing the amdvlk stuff yet I probably should have waited to report till I actually had time to follow up I have been very busy with work

[kd-11]

This should have been fixed. There were multiple regressions with other games as well due to some MRT changes.

it has indeed been fixed
