# Zenpower
Zenpower is Linux kernel driver for reading temperature, voltage(SVI2), current(SVI2) and power(SVI2) for AMD Zen family CPUs.
Zenpower3 is a Linux kernel driver for reading temperature, voltage(SVI2), current(SVI2) and power(SVI2) for AMD Zen family CPUs, now with Zen 3 support!
Make sure that your Linux kernel have support for your CPUs as Zenpower is using kernel function `amd_smn_read` to read values from SMN. A fallback method (which may or may not work!) will be used when it is detected that kernel function `amd_smn_read` lacks support for your CPU.
For AMD family 17h Model 70h (Ryzen 3000) CPUs you need kernel version 5.3.4 or newer or kernel with this patch: https://patchwork.kernel.org/patch/11043277/
