Dota2 does not work if Steam is on #42

Closed silikeite closed 4 months ago

silikeite commented 5 years ago

I have primus_vk running on my Arch install. I installed both primus_vk and lib32-primus_vk from the official repositories and edited nvidia_icd.json to point to nv_vulkan_wrapper.so to make it work. I was able to test it using pvkrun vkcube with no problem. Running pvkrun ./dota.sh while Steam is off launches Dota2 properly without issues, except for Dota complaining that it lost connection to Steam. Running pvkrun ./dota.sh while Steam is on causes the game to segfault immediately. I have tried this with both steam-native and steam-runtime. I have also tried running both steam-native and steam-runtime with the pvkrun command, and I still get the same error.

The following is printed on the command prompt:

$ pvkrun ./dota.sh

I've managed to get dota2 running on my system flawlessly (see https://github.com/felixdoerre/primus_vk/issues/15#issuecomment-442394361). Those tests were definitely with steam running. From the output, it seems, you got up until here: https://github.com/felixdoerre/primus_vk/blob/master/primus_vk.cpp#L236 we need an exact location of the crash to determine what is happening. I'd suggest you build primus_vk from source and run it with a debugger or add debug print statements to determine where exactly the crash is happening.

silikeite commented 5 years ago

I'm sorry but I'm not that much of a developer (well, for native apps at least) myself. I tried building directly from the latest git and I still get the exact same error as with the packaged version from Arch. May I ask how to run with a debugger/what debugger should I use?

I presume to actually debug I'm supposed to do something else?

Steam prints this out to console

felixdoerre commented 5 years ago

for debugging that segfault gdb should be perfectly fine, when the executable you want to debug has command line args, you need to invoke gdb --args ./executable arg1 arg2. In your case Dota seems to be wrapped by a shell script. So you would need to look inside the shell script and see where the actual game executable is started and add gdb --args there.

From my limited understanding, vkGetPhysicalDeviceProperties() in Vulkan itself fails if and only if Steam is running while playing a game that connects to Steam?

felixdoerre commented 5 years ago

Yup, that is what it looks like. Can you please obtain a backtrace (gdb command bt) when gdb pauses after the segfault?

i get the same thing on both steam-native and steam-runtime (both with and without ENABLE_PRIMUS_LAYER=1)

On my system Dota launches on Vulkan if i uninstall primus_vk (though obviously on the intel card)

felixdoerre commented 5 years ago

it's not that surprising that the problem is in vkGetPhysicalDeviceProperties. Without primus_vk installed the application has only the Intel physicalDevice to put into vkGetPhysicalDeviceProperties. With primus_vk installed, the application has both physical devices at it's disposal, and is reponsible for choosing the intel device (as the dedicated device will not be able to create a surface). With primus_vk enabled, the application only gets the dedicated device and probably will put that into vkGetPhysicalDeviceProperties.

The next step would probably to install debug symbols for libvulkan and find the exact location where it crashes (https://github.com/KhronosGroup/Vulkan-Loader/blob/master/loader/trampoline.c#L728 ). Then we'd know which arguments are wrongly put into this vulkan function, and who is responsible for the crash.

silikeite commented 5 years ago

I guess that would also explain why I can't launch any vulkan apps directly to run on my Intel gpu, instead having to specify VK_ICD_FILENAMES.

How would you "install debug symbols for libvulkan"? (Sorry, I'm not used to this) Is there some package that I 'm supposed to install, or am I supposed to recompile vulkan-icd-loader or something?

felixdoerre commented 5 years ago

It seems that on arch you need to recompile the package with options (debug !strip) see here: https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces#General

silikeite commented 5 years ago

I can't seem to find a non-precompiled version of vulkan-icd-loader in AUR. In that case would I need to somehow write a custom package for it (...which I don't know how to do) or use a different method?

Running without steam still works The output from gdb for the working (without steam) dota2 is a bit too long to fit here so I posted it to pastebin https://pastebin.com/7v9DWB3e

felixdoerre commented 5 years ago

As this seems to get increasingly weird I've installed dota2 on my system and tested it. It runs flawlessly, also with steam (and even if started from within steam).

To the backtrace: (physicalDevice=0x1, pProperties=0x7fffffffb8b0) it seems the first parameter passed to vkGetPhysicalDeviceProperties is wrong. That should be a memory address of a VkPhysicalDevice-object, which 0x1 definitively isn't.

silikeite commented 5 years ago

Maybe there is something wrong with how I installed primus_vk? I switched back to the official package for Arch. For primus_vk to work for me i have to symlink nvidia_icd.json to nv_vulkan_wrapper.json (maybe this is the source of the bug?)

This time I got a different value for physicalDevice

physicalDevice=0x4400, pProperties=0x7fffffffbb20

in gdb

felixdoerre commented 5 years ago

0x4400 probably isn't a valid address either. What do you currently have in /usr/share/vulkan/icd.d? Have you tried removing nvidia_icd.json instead of replacing it with a symlink?

silikeite commented 5 years ago

Contents of icd.d would be intel_icd.i686.json intel_icd.x86_64.json
nvidia_icd.json (symlink to nv_vulkan_wrapper.json) nvidia_icd.json.bak nv_vulkan_wrapper.json

I deleted nvidia_icd.json and got physicalDevice=0x0, pProperties=0x7fffffffbca0 while steam is on. Steam off still works

When testing dota2 on your system, what hardware/distro/icd setup did you use?

silikeite commented 5 years ago

For kicks I tried running vulkaninfo.... and I got a segfault

What I still don't understand is why having Steam running in the background would make any difference

felixdoerre commented 5 years ago

Ooh sorry, I missed your question about my setup, where Dota2 runs:

silikeite commented 5 years ago

I am on:

Could the default package being built with libGLX_nvidia.so.0 be the issue?

silikeite commented 5 years ago

I recompiled with libGL.so.1 but unfortunately the problem persists

silikeite commented 5 years ago

I just thought of something Does Steam have its own icd.d?

felixdoerre commented 5 years ago

No, steam only brings a few layers: ~/.local/share/vulkan/implicit_layer.d/steam*

silikeite commented 5 years ago

I tried running Fallout New Vegaa on Proton as well Running it with Intel works... with Nvidia it crashes right afrer the intro (dmesg reporrs a vulkan segfault as well)

I can't test Fallout NV without Steam because DRM but it seems to me that something really wrong happens once Steam is involved

felixdoerre commented 5 years ago

you cold try to delete those implicit layers to forcefully disable them (and hope to be fast enough before steam puts them back in there).

adrfantini commented 5 years ago

I would like to test on my setup as well. I also run bumblebee on an nvidia card (960M) on Arch. It's not clear to me: once I installed primus_vk and lib32_primus_vk and added ENABLE_PRIMUS_LAYER=1 optirun %command% -vulkan, is there any other step I should take? I'm also trying to run Dota2 and I also get segfaults in this way, both with native and runtime steam.

greyltc commented 5 years ago

In case it helps you here, I've had good success with running proton steam stuff (in Arch) with this launch method:

ENABLE_PRIMUS_LAYER=1 VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nv_vulkan_wrapper.json:/usr/share/vulkan/icd.d/intel_icd.x86_64.json optirun steam-native
vernwinkle commented 4 months ago

I'm having difficulties running steam on my discrete GPU, https://github.com/ValveSoftware/Proton/issues/150#issuecomment-2198117039

felixdoerre commented 4 months ago

@vernwinkle I don't believe your issue has anything to do with the symptoms mentioned here. Also in the comment in the Proton repository I don't see any indication that primus_vk is running (only that the layer is installed). With that information I cannot help you. Does primus_vk work generally on your system? Did you try launching steam with gamemoderun instead of running a single game with it? A simple check to see if gamemoderun is actually launching primus_vk might be vulkaninfo | grep deviceName and check if the name of the discrete GPU is printed. Please create a new issue and describe what you were doing, and what the expected and observed behavior is.
