Setting custom profile through rocm-smi #57

Closed sabbaghm closed 5 years ago

sabbaghm commented 5 years ago

How exactly we can define and set a custom power profile for an RX 580 (polaris) GPU through rocm-smi ?

When I try: rocm-smi --setprofile 6

I receive the following error: ======================== ROCm System Management Interface ======================== Unable to write to sysfs file /sys/class/drm/card0/device/pp_power_profile_mode GPU[0] : Unable to set CUSTOM Power Profile values WARNING: One or more commands failed ======================== End of ROCm SMI Log ========================

rocm-smi --showprofile prints:

I have the latest version of ROCm from AMD repos on Ubuntu 16.04. Thank you!

I believe to set a custom profile, you need to actually fully define the profile in your command.

SMU7 (which is used on Polaris 10 GPUs like what you have) requires 8 values to be passed in to define those profiles. This is defined in smu7_set_power_profile_mode in the smu7_hwmgr.c file in your driver.

The fields are, in order:

  1. Do you want to have a custom SCLK (graphics clock) profile? 1 if yes, 0 if no.
  2. SCLK_UP_HYST
  3. SCLK_DOWN_HYST
  4. SCLK_ACTIVE_LEVEL
  5. Do you want to have a custom MCLK (memory clock) profile? 1 if yes, 0 if no.
  6. MCLK_UP_HYST
  7. MCLK_DOWN_HYST
  8. MCLK_ACTIVE_LEVEL

These values are all in a quoted string argument to --setprofile. For example, this is an example of setting the custom profile to be identical to the 3D_FULL_SCREEN profile on my Fiji (also SMU7) GPU:

$ rocm-smi -d 1 --showprofile

@jlgreathouse Thank you! I could successfully set the custom profile using the suggested command template: rocm-smi --setprofile "CustomSCLKFlag SCLK_UP_HYST SCLK_DOWN_HYST SCLK_ACTIVE_LEVEL CustomMCLKFlag MCLK_UP_HYST MCLK_DOWN_HYST MCLK_ACTIVE_LEVEL"
