Build Status

i2c driver for AURA capable GPUs

Installing

You can get releases for Fedora, RHEL, CentOS, OpenSUSE, and OpenMandriva from my Copr.

If you wish to use this with Secure Boot, follow this guide.

After Install

The i2c-dev module is required:

List all i2c devices with:

sudo i2cdetect -l

It will output something like

i2c-3   smbus           SMBus PIIX4 adapter port 4 at 0b00      SMBus adapter
i2c-10  i2c             AMDGPU DM i2c hw bus 4                  I2C adapter
i2c-1   smbus           SMBus PIIX4 adapter port 2 at 0b00      SMBus adapter
i2c-8   i2c             AMDGPU DM i2c hw bus 2                  I2C adapter
i2c-6   i2c             AMDGPU DM i2c hw bus 1                  I2C adapter
i2c-4   i2c             AMDGPU DM i2c hw bus 0                  I2C adapter
i2c-11  i2c             AURA GPU adapter                        I2C adapter
i2c-2   smbus           SMBus PIIX4 adapter port 3 at 0b00      SMBus adapter
i2c-0   smbus           SMBus PIIX4 adapter port 0 at 0b00      SMBus adapter
i2c-9   i2c             AMDGPU DM i2c hw bus 3                  I2C adapter
i2c-7   i2c             dmdc                                    I2C adapter
i2c-5   i2c             dmdc                                    I2C adapter

Here we can see this module "AURA GPU adapter" is detected as device number 11. We can now scan that device with:

sudo i2cdetect -y 11

It should output all clients available on that bus:

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
