[BUG] asynchronous reprojection - Insufficient permission to create high priority queue. #660

Open Links2004 opened 8 months ago

Links2004 commented 8 months ago

Describe the bug cap_sys_nice is set but Insufficient permission to create high priority queue. is shown in the log and asynchronous reprojection is "not supported"

$ getcap ~/.steam/steam/steamapps/common/SteamVR/bin/linux64/vrcompositor-launcher
/home/links/.steam/steam/steamapps/common/SteamVR/bin/linux64/vrcompositor-launcher cap_sys_nice=eip

the only simmular issue i found is: https://github.com/NixOS/nixpkgs/issues/217119 since it looks like that Steam Linux Runtime is using bwrap too.

$ ps aux | grep bwrap

To Reproduce Steps to reproduce the behavior:

  1. Go to start SteamVR with steam linux runtime
  2. look in log or settings page

Expected behavior the steam linux runtime chroot / isolation do allow the use of cap_sys_nice and as a result asynchronous reprojection can be enabled.

I don't think SteamVR runs inside a pressure-vessel based runtime by default, so I don't think this is a problem with CAP_SYS_NICE. I thought NVIDIA didn't support async reprojection in general yet

Links2004 commented 8 months ago

the NVIDIA driver supports it since a long time (2021) see:

https://www.nvidia.com/download/driverResults.aspx/176525/en-us/

Added support for VK_QUEUE_GLOBAL_PRIORITY_REALTIME_EXT from the VK_EXT_global_priority extension. This enables support for asynchronous reprojection in SteamVR.

VK_QUEUE_GLOBAL_PRIORITY_REALTIME_EXT is supported on Pascal GPUs and newer.

Global priorities other than VK_QUEUE_GLOBAL_PRIORITY_MEDIUM_EXT require root privileges or the CAP_SYS_NICE capability.

and vulkaninfo shows support.

The same thing started happening on a working 1.27.5 install. So it's something the Steam client did. I see that vrstartup.sh / vrsetup.sh is no started under Sniper, so I assume this is what broke a bunch of things.

Edit: Conclusions after a short investigation.

I'm unsure if it's even possible to elevate your permission in the container.

If I have more time, I may try to wrap srt-bwrap in a script that skips the container for vrstartup.sh.

Also just commenting to +1 as the issue is still affecting me.

I can work around the issue by launching ~/.steam/steam/steamapps/common/SteamVR/bin/vrstartup-helper.sh manually instead of from inside Steam and then async reprojection works perfectly, but, often times when I shut down SteamVR after it has been launched this way it just crashes my entire computer and that's no good.

However, games like DCS and Microsoft Flight Simulator are unplayable without async, so finding a better solution to this problem that doesn't risk hard crashing my computer would be nice.

(Edit: System-wide crash doesn't seem to happen on Wayland.)

When I launch SteamVR the normal way (through Steam) I see this in vrcompositor.txt
