# tuned-amdgpu
|
|
|
|
hacky solution to integrate AMDGPU power profile control in `tuned` with Ansible
|
|
|
|
## Notable variables
|
|
- Power control: (float) multipliers to determine power _limits_ from board power _capability_
|
|
- `power_max_default_multi`: Controls power for the generated `default` GPU profile. Provided: `0.75` for 75% board power capability.
|
|
- `power_max_custom_multi`: Controls power for the generated `custom` GPU profile. Provided: `1.0` for 100% board power capability.
|
|
- `card`: Sets the `card#` to use in the qualified `sysfs` path `/sys/class/drm/{{ card }}/device/pp_power_profile_mode`. Default: `card0`
|
|
- `base_profiles`: List of base tuned profiles to clone in the new AMDGPU profiles. Defaults (based on `Fedora`):
|
|
- `balanced`
|
|
- `desktop`
|
|
- `latency-performance`
|
|
- `network-latency`
|
|
- `network-throughput`
|
|
- `powersave`
|
|
- `virtual-host`
|
|
- `amdgpu_profiles`: Mapping of AMDGPU power profiles (`name`/`value`) defined in the `sysfs` path above. Varies, sample is with a 6900XT. Defaults:
|
|
- `{ name: 'default', value: 0 }`
|
|
- `{ name: 'custom', value: 6 }`
|
|
|
|
## Example profiles/output
|
|
```
|
|
$ tuned-adm profile
|
|
Available profiles:
|
|
- accelerator-performance - Throughput performance based tuning with disabled higher latency STOP states
|
|
- balanced - General non-specialized tuned profile
|
|
- balanced-amdgpu-custom - balanced + TCP/RAID tweaks + AMDGPU pp_power_profile_mode = 6 (custom)
|
|
- balanced-amdgpu-default - balanced + TCP/RAID tweaks + AMDGPU pp_power_profile_mode = 0 (default)
|
|
- desktop - Optimize for the desktop use-case
|
|
- desktop-amdgpu-custom - desktop + TCP/RAID tweaks + AMDGPU pp_power_profile_mode = 6 (custom)
|
|
- desktop-amdgpu-default - desktop + TCP/RAID tweaks + AMDGPU pp_power_profile_mode = 0 (default)
|
|
- hpc-compute - Optimize for HPC compute workloads
|
|
- intel-sst - Configure for Intel Speed Select Base Frequency
|
|
- latency-performance - Optimize for deterministic performance at the cost of increased power consumption
|

|
|
- latency-performance-amdgpu-default- latency-performance + TCP/RAID tweaks + AMDGPU pp_power_profile_mode = 0 (default)
|
|
- network-latency - Optimize for deterministic performance at the cost of increased power consumption, focused on low latency network performance
|
|
- network-latency-amdgpu-custom- network-latency + TCP/RAID tweaks + AMDGPU pp_power_profile_mode = 6 (custom)
|
|
- network-latency-amdgpu-default- network-latency + TCP/RAID tweaks + AMDGPU pp_power_profile_mode = 0 (default)
|
|
- network-throughput - Optimize for streaming network throughput, generally only necessary on older CPUs or 40G+ networks
|
|
- network-throughput-amdgpu-custom- network-throughput + TCP/RAID tweaks + AMDGPU pp_power_profile_mode = 6 (custom)
|
|
- network-throughput-amdgpu-default- network-throughput + TCP/RAID tweaks + AMDGPU pp_power_profile_mode = 0 (default)
|
|
- optimize-serial-console - Optimize for serial console use.
|
|
- powersave - Optimize for low power consumption
|
|

|
|
- powersave-amdgpu-default - powersave + TCP/RAID tweaks + AMDGPU pp_power_profile_mode = 0 (default)
|
|
- throughput-performance - Broadly applicable tuning that provides excellent performance across a variety of common server workloads
|
|
- virtual-guest - Optimize for running inside a virtual guest
|
|
- virtual-host - Optimize for running KVM guests
|
|
- virtual-host-amdgpu-custom - virtual-host + TCP/RAID tweaks + AMDGPU pp_power_profile_mode = 6 (custom)
|

|
|
Current active profile: network-latency-amdgpu-default
