Help needed - amdgpu linux config files

dreadknot2077 · March 22, 2023, 11:45pm

do i have the made right for the `amdgpu-custom-state.cardX file if thats what its supposed to or what

For Navi (and Radeon7) we can only set highest SCLK & MCLK, “state 1”:

OD_SCLK:
0: 500Mhz
1: 2520Mhz
OD_MCLK:
0: 850Mhz
1: 1050MHz

More fine-grain control of clocks and voltages are done with VDDC curve:

OD_VDDC_CURVE:
0: 850MHz @ 750mV
1: 2520MHz @ 1050mV

Force power limit (in micro watts):

FORCE_POWER_CAP: 105000000
FORCE_PERF_LEVEL: manual

the original pp_od_clk_voltage file looks like this

OD_SCLK:
0: 850Mhz
1: 2520Mhz
OD_MCLK:
0: 500Mhz
1: 850MHz
\00\00\00\00\00\00OD_VDDGFX_OFFSET:
-60mV
\00\00\00\00\00\00\00\00\00OD_RANGE:
SCLK: 500Mhz 2520Mhz
MCLK: 850Mhz 1050Mhz
\00\00\00\00\00\00\00\00\00\

this is for my 6700xt on pop os with corectrl app

what that correct format to struture this an how an were do the right files go

## AMDGPU Clocks

### Introduction

This is a simple script that can be used to set custom power states for recent
AMD GPUs that are driven by **amdgpu** Linux kernel driver. The script is able
to set custom clocks, voltages and some other power states, assuming that
Radeon OverDrive is enabled in the driver. The OverDrive is not enabled by
default as of Linux 5.x, it can be enabled by setting 14th bit (0x4000) of a
**ppfeaturemask** amdgpu driver to 1. For example, setting
**amdgpu.ppfeaturemask=0xfffd7fff** or **amdgpu.ppfeaturemask=0xffffffff**
kernel boot option will do the trick. This would enable amdgpu driver sysfs
API that allows fine grain control of GPU power states (GPU & VRAM clocks &
voltages, depending on actual hardware).
It should work on Polaris, Vega (unfortunately Vega found on AMD APUs does
not expose this API) and Navi cards, and it can be used to easily manage
multiple AMD graphics cards.

### How does it work
