Issue setting overclock values on Nvidia card #170

Open dylanparry opened 5 years ago

dylanparry commented 5 years ago

Describe the bug I get an error when I attempt to overclock my Nvidia card

To Reproduce Steps used to reproduce the behavior:

  1. Launch gamemod with the following config file:
[general]
; The reaper thread will check every 5 seconds for exited clients and for config file changes
reaper_freq=5

; The desired governor is used when entering GameMode instead of "performance"
desiredgov=performance
; The default governer is used when leaving GameMode instead of restoring the original value
defaultgov=powersave

; GameMode can change the scheduler policy to SCHED_ISO on kernels which support it (currently
; not supported by upstream kernels). Can be set to "auto", "on" or "off". "auto" will enable
; with 4 or more CPU cores. "on" will always enable. Defaults to "off".
softrealtime=off

; GameMode can renice game processes. You can put any value between 0 and 20 here, the value
; will be negated and applied as a nice value (0 means no change). Defaults to 0.
renice=0

; By default, GameMode adjusts the iopriority of clients to BE/0, you can put any value
; between 0 and 7 here (with 0 being highest priority), or one of the special values
; "off" (to disable) or "reset" (to restore Linux default behavior based on CPU priority),
; currently, only the best-effort class is supported thus you cannot set it here
ioprio=0

; Sets whether gamemode will inhibit the screensaver when active
; Defaults to 1
inhibit_screensaver=1

[gpu]

; Setting this to the keyphrase "accept-responsibility" will allow gamemode to apply GPU optimisations such as overclocks
apply_gpu_optimisations=accept-responsibility

; The DRM device number on the system (usually 0), ie. the number in /sys/class/drm/card0/
gpu_device=1

; Nvidia specific settings
nv_powermizer_mode=1
nv_core_clock_mhz_offset=150
nv_mem_clock_mhz_offset=1000
  1. Run gamemodrun glxgears
  2. View output of 'systemctl --user status gamemode.service`
  3. See error:

Expected behavior The GPU should be overclocked.

System Info (please complete the following information):

Additional context I've found that the only settings that allow my GPU to be overclocked are:

Which differ slightly from the ones that are trying to be used in the above status log.

What GPU and driver version are you using?

dylanparry commented 5 years ago

GPU is GeForce GTX 1050, and driver version is 430.40

mdiluz commented 5 years ago

Hmm, wouldn't be surprised if something has changed in the Nvidia driver since I implemented this - for instance on my machine nvidia-settings doesn't even expose GPUGraphicsClockOffset or GPUMemoryTransferRateOffset anymore.

What happens when you run gamemoded -t? I get this when I check now, on a laptop GPU (perhaps part of the problem).

I get this:

~$ gamemoded -t

: Tests Failed!

Not sure what the "other client" it refers to is as there's no games running.

From the reading I did, it looks like GPUGraphicsClockOffset and GPUMemoryTransferRateOffset were replaced with GPUGraphicsClockOffsetAllPerformanceLevels and GPUMemoryTransferRateOffsetAllPerformanceLevels respectively. I couldn't find anywhere that knew exactly when this change occurred, but it looks like it was some time during the 390.x series of drivers. I also couldn't find any official documentation for this anywhere :\

mdiluz commented 5 years ago

Not the best log message, but:

ERROR: gamemode_query_status failed to return other client connected (expected 1)!

Is complaining that with an extra fake client connected, gamemode_query_status didn't return 1 to say that there was a client active. That's strange. Does the issue repeat? If so, the output of journalctl --user --unit=gamemoded --follow during the same time as running the tests would be interesting to see.

The tests didn't even get to taking a look at the GPU stuff anyway, because of that core failure :(

Ugh yeah, that's happened before, and now the code would need a special case for each version. I'm starting to think more complicated GPU overclocking should be handled outside of GameMode, using the custom start/end scripts.

This is what I get:

I've resorted to running a start/end script that does the overclocking manually for now, and that works just fine.
