Hang on startup after bd722f786f5a74f8282d903bd5eb3d331c4cd920 on NV

Hangs on startup on NVIDIA after https://github.com/ValveSoftware/gamescope/commit/bd722f786f5a74f8282d903bd5eb3d331c4cd920

Note that this is not with any of the reshade stuff enabled.

Not sure what is bad about this commit. The log says its grabbing 2 as the async compute queue and 0 as the general one.

Seems like we hang in a CVulkanDevice::wait, despite not ever using the general queue anywhere at all. Seems like merely grabbing both queues here seems to break vkWaitSemaphores.

Nothing interesting in validation...

I've filed internal bug 4330963 to track investigation within NVIDIA.

same issue here with wayland+wlroots+sway+nvidia on Arch GNU/Linu

 gamescope

this was working fine before.

Issue continues in 3.13.8

@HWG90 I've just updated my nvidia-fix branch, which has a workaround for the current nvidia driver bug w/ gamescope, to the latest git revision of gamescope. I've tested my building and running gamescope from my branch w/ nvidia, and it seems to work as long as you set ENABLE_GAMESCOPE_WSI=0 (e.i. ENABLE_GAMESCOPE_WSI=0 gamescope <params> -- <game>) if you're using hybrid graphics, you'll have to run gamescope like so: ENABLE_GAMESCOPE_WSI=0 gamescope --prefer-vk-device $(env MESA_VK_DEVICE_SELECT=list vulkaninfo) <params> -- <game>

to build from my branch:

git clone https://github.com/sharkautarch/gamescope.git
cd gamescope
git checkout nvidia-fix
meson setup -Dc_args="-Wno-uninitialized -Wno-maybe-uninitialized" -Dcpp_args="-Wno-uninitialized -Wno-maybe-uninitialized" --reconfigure build
ninja -C build
meson install -C build

ReillyBrogan commented 10 months ago

I would note that that revert breaks gamescope on AMD cards at least, and likely Intel ones as well. In Solus we handled this by building 3.13.8 twice, once with the Nvidia revert applied and once without. The Nvidia revert build is installed at /usr/bin/gamescope-nvidia while the unpatched build is at /usr/bin/gamescope. Just a though on how to handle this if there are any other distribution maintainers watching this thread.

Thank you for providing this. vkcube now starts, but it stops after a few seconds, then after exactly 30 seconds later, I get the following spammed forever in the terminal until I SIGKILL gamescope-wl:

Try running it with: ENABLE_GAMESCOPE_WSI=0 gamescope --prefer-vk-device “10de:$(vulkaninfo -o /dev/stdout | grep -i 10de -A1 | tail -n 1 | tr ‘x’ ‘ ‘ | awk ‘{print $4}’)” <params> — <game>

You could also try building from my nvidia-fix-and-vblank-debug-extra-experimental-v4.5 idk if said branch would work if nvidia-fix branch doesn’t for you

Try running it with:

I have tried using the --prefer-vk-device flag before, sadly it still doesn't work.

nvidia-fix-and-vblank-debug-extra-experimental-v4.5

The new branch doesn't seem to work either.

Huh, strange… Can you provide the terminal output of gamescope (up until it just repeatedly outputs vblankmanager: write failed: Resource temporarily unavailable)

Also are you also using 535 nvidia drivers? (Those are what I’m using right now, tho I’m currently specifically on the 6.6 Linux kernel w/ the 535 dkms nvidia drivers)

Hmmm I feel like I’ve seen that vblankmanager: write failed: Resource temporarily unavailable message before, but I don’t remember the context for it…

I have tried using the --prefer-vk-device flag before, sadly it still doesn't work.

Did you also try running it with --prefer-vk-device “10de:$(vulkaninfo -o /dev/stdout | grep -i 10de -A1 | tail -n 1 | tr ‘x’ ‘ ‘ | awk ‘{print $4}’)”

Because I think that above may work whereas —prefer-vk-device $(env MESA_VK_DEVICE_SELECT=list vulkaninfo) doesn’t

That just outputs 1f07 which is what I tried before.

Small nitpick: Please make sure to convert your backticks and backquotes to ticks and quotes when asking to run commands :)

nvidia-dkms 535.113.01-2

$ ENABLE_GAMESCOPE_WSI=0 gamescope -w 2560 -h 1440 -e -- steam

So the problem is with how the 545 series of drivers handle things.

Can confirm that both your branches (nvidia-fix and nvidia-fix-and-vblank-debug-extra-experimental-v4.5) work.

Not perfectly, but I can actually load Half-Life 2 and a few other games, using GE_Proton8_24 where needed.

Guess we'll just have to wait for @cubanismo to hopefully fix it internally :)

Huh, maybe there was a really new update to 545 that unbroke whatever was causing an issue? idk

Can you run nvidia-smi after running gamescope to confirm that gamescope is using the nvidia gpu w/ your 545 driver? (Just checking that it isn't just using a different gpu in the case that your system has another non-nvidia gpu)

If this is a reply to me, it's a desktop with only a 3060ti for graphics (no APU or iGPU at all).

Granted, just to cover my bases but on a slightly unrelated note, I have to run gamescope with __GL_THREADED_OPTIMIZATIONS=0 as per https://github.com/ValveSoftware/gamescope/issues/526#issuecomment-1744609920 - otherwise the error in that thread occurs for me. But this applies to "normal" gamescope (pre-present day issue here) as well.

no just try the nvidia-fix-and-vblank-debug-extra-experimental-v4.6 branch w/ nvidia 535 the v4.6 might just feel a bit smoother for you (tho it might not be noticable) (compared to the v4.5 branch)

Sure, it feels OK :) Thank you!

jkozera commented 10 months ago

@sharkautarch I'm just testing nvidia-fix-and-vblank-debug-extra-experimental-v4.7 because I also encounter vblankmanager: write failed: Resource temporarily unavailable errors.

I got an STL exception from std::clamp with !(__hi < __lo), so I've replaced the debugging calls with a custom safe_clamp:

template<class T>
constexpr const T& safe_clamp(const T& v, const T& lo, const T& hi)
{
    if (lo > hi) {
           std::cout << "lo > hi" << lo << " " << hi << "; returning lo\n";
           return lo;
    }
    return std::clamp(v, lo, hi);
}

And now I get many of these

lo > hi16666666 7638888; returning lo
lo > hi18316666 8333332; returning lo
lo > hi16414964 7638888; returning lo
lo > hi18064964 7291666; returning lo

which are probably not very helpful because I don't see which call these come from, but I just thought you might be interested in knowing about this STL exception.

Do you know which gamescope cpp file is generating these exceptions from? (or is calling whatever STL function/method that then produces these exceptions?)
If you don't, you should be able to figure it out by:

first making sure your linux OS is set to dump coredumps:

if ! grep -qi 'kernel.core_pattern' /etc/sysctl.conf; then
sudo sh -c 'echo "kernel.core_pattern=core.%p.%u.%s.%e.%t" >> /etc/sysctl.conf'
sudo sysctl -p
fi
ulimit -c unlimited

run gamescope again to generate the core dump for the STL exception
run ls -lt | less and you should see a file that starts with the word core near/at the top
if you're on a distro like arch, make sure you have the debuginfod package installed
Analyze the core dump with gdb: gdb <path/to/gamescope-binary> ./<core dump file>
get a backtrace by entering: bt or: thread apply all bt let me know what you find from that see also: https://linuxconfig.org/gdb-debugging-tutorial-for-beginners

It's definitely vblankmanager.cpp changed in the nvidia-fix-and-vblank-debug-extra-experimental-v4.7 branch, because after I've replaced the std::clamp calls in that file, the exceptions no longer happen.

Ok, can you still try to get the core dump from the exceptions, and then analyze it with gdb as I showed You might be able to see the specific line in vblankmanager.cpp that had the std::clamp which caused the exception

I just realized that I ordered the parameters to std::clamp wrong lol

I just fixed all of the std::clamp and pushed out the fix to the nvidia-fix-and-vblank-debug-extra-experimental-v4.7 branch

Thanks for spotting that!

also let me know if there are still any issues with nvidia-fix-and-vblank-debug-extra-experimental-v4.7

jkozera commented 10 months ago

Now it seems better, because it runs for a bit longer time, but it still crashes, in the same line. Maybe it's because of larger latency occuring? Because it crashes shortly after VBlankTimeInfo_t receive latency: 2.42ms while previous latencies were on order of 0.01ms.

ok I've just pushed out another fix, hopefully it at least doesn't crash on the same exact line in vblankmanager.cpp again...

jkozera commented 10 months ago

It doesn't crash anymore, but sadly it still hangs with "vblankmanager: write failed: Resource temporarily unavailable". The "receive latency" messages stop appearing, then the game hangs, then after a few (10-30) seconds the "vblankmanager: write failed: Resource temporarily unavailable" start appearing repeatedly in terminal.

What nvidia driver are you using? Some people have said that the problem goes away after switching from nvidia 545 to nvidia dkms 535 I myself am using the nvidia dkms 535 driver

jkozera commented 10 months ago

I use 545. I haven't tried switching back to an older one yet, it's on my TODO list. :)

Can you tell me how to fix this error when building from your branch @sharkautarch? I have a 3090 and would like to try this fix with the newest nvidia drivers src/meson.build:95:18: ERROR: Include dir reshade/source does not exist.

I'm running this command:

meson setup -Dc_args="-Wno-uninitialized -Wno-maybe-uninitialized" -Dcpp_args="-Wno-uninitialized -Wno-maybe-uninitialized" --reconfigure build

sharkautarch commented 10 months ago

Replying to https://github.com/ValveSoftware/gamescope/issues/948#issuecomment-1842093063

I believe you just need to also run git submodule update --init --recursive and then run ninja -C build again

ageisen2000 commented 10 months ago

@sharkautarch, thank you!! The build worked. ~This is probably a dumb question.... but where do I get the binary that was built? How do run the gamescope command with it?~

Figured it out, missed the meson install -C build step

ageisen2000 commented 10 months ago

@sharkautarch, do you know if this patch would cause artifacting issues on Nvidia cards? I can't launch my game without a lot of artifacting / glitchy graphics.

@sharkautarch, do you know if this patch would cause artifacting issues on Nvidia cards? I can't launch my game without a lot of artifacting / glitchy graphics.

For which? nvidia-fix or nvidia-fix-and-vblank-debug-extra-experimental-v4.7?

Well for either case, try my new branch: nvidia-fix-and-vblank-debug-extra-experimental-v4.8

ageisen2000 commented 10 months ago

I was using the 4.7 patch. I'll try 4.8 tonight and let you know how it goes

The vulkan beta driver released yesterday claims to Fix Gamescope hang on startup [Linux] but the current master still hangs for me (or gives no video output anyway, no errors from gamescope) in embedded mode. I didn't try nested.

ageisen2000 commented 10 months ago

@sharkautarch , the 4.8 branch seems to have crashed my computer when I ran it from a TTY. I couldn't swap TTYs and I didn't see any logs or anything. Command I ran: gamescope -W 3440 -H 1440 --immediate-flips -O DP-1 -e -- steam

I'm considering just giving up on Nvidia support for this for now, but if you need help debugging or anything shoot me a message and maybe we could work together over discord or something

detiam commented 10 months ago

I'm on driver 545, and with branch nvidia-fix-and-vblank-debug-extra-experimental-v4.8 I can run gamescope on nested mode (under X) perfectly, on embedded mode (under tty) without option --adaptive-sync it works fine, with this option gamescope will freeze, but program still running, and my monitor shows it only have 48hz refresh rate. log.txt

EDIT: oh actually if only have --immediate-flips set, on my end everything fine, but log above have

drm: Immediate flips are not supported by the KMS driver

so I guess on my end --immediate-flips dose nothing.

sharkautarch commented 10 months ago

I'm not surprised that gamescope still crashing with certain options with nvidia.. I might try compiling gamescope w/ clang sanitizers and vulkan validation and see if I find anything that pops up when using --immediate-flips or --adaptive-sync

EDIT: does anything change if you add the environment variable ENABLE_GAMESCOPE_WSI=0 gamescope --immediate-flips ... ?

When I enable that environment variable it actually loads up.

maybe try running export VK_INSTANCE_LAYERS=VK_LAYER_KHRONOS_validation ENABLE_GAMESCOPE_WSI=0 gamescope --immediate-flips ... and see if it prints anything else useful (you might need to add > some_file.out at the end so that you'll be able to see what it printed out)

log.txt with command

VK_INSTANCE_LAYERS=VK_LAYER_KHRONOS_validation ENABLE_GAMESCOPE_WSI=0 gamescope --adaptive-sync -- vkcube > log.txt 2>&1

it will first load up, show vkcube spin for one second then freeze, monitor shows 48 refresh rate, when I press esc vkcube will exit and gamescope exit.

ageisen2000 commented 10 months ago

I ran

sudo setcap 'CAP_SYS_NICE=eip' /usr/local/bin/gamescope
VK_INSTANCE_LAYERS=VK_LAYER_KHRONOS_validation ENABLE_GAMESCOPE_WSI=0 gamescope -W 3440 -H 1440 -r 175 --immediate-flips -O DP-2 -- glxgears > glxgearsout.log

And got a bunch of garbage on the screen. I could see the app, but weirdly enough even in TTY mode I saw a steam window. Idk whats going on there.

I think there's also an issue with running gamescope w/ nvidia after setting 'CAP_SYS_NICE=eip' tho I think I might be able to find a workaround to that specifically

EDIT: I just found a workaround to the issue I've experienced with running gamescope w/ nvidia after setting 'CAP_SYS_NICE=eip' ... Since you haven't mentioned issues with 'CAP_SYS_NICE=eip', maybe it works fine for you since you are using the nvidia 545 driver, whereas I'm currently using the nvidia 535 dkms driver...

For --immediate-flips, I'm guessing that it probably won't be able to work, or that is, even if we could find a way to prevent gamescope on nvidia from crashing when using it, it'll probably just do nothing. Just gotta hope that it'll be patched in an nvidia driver update... fingers crossed

If you want to try to reduce latency, try running gamescope w/ MESA_VK_WSI_PRESENT_MODE=mailbox ENABLE_GAMESCOPE_WSI=0 gamescope ... or MESA_VK_WSI_PRESENT_MODE=mailbox ENABLE_GAMESCOPE_WSI=0 gamescope ... -- env MESA_VK_WSI_PRESENT_MODE=immediate ...

unhappy-ending commented 10 months ago

Hello, just adding some feedback. I could run nvidia+gamescope on anything that was native wayland apps just fine. Problem was anything using Xwayland would give me a black screen. I installed the 535.43.20 vulkan beta driver @brain-anti-freeze posted about earlier and it fixed gamescope for me. I'm not using the @sharkautarch nvidia-fix patch, just vanilla gamescope from the Gentoo repo.
