Linux Kernel for SiFive HiFive P550 Premier Arch Linux Image

The PKGBUILD file in this repository is used to build the Linux kernel for the SiFive HiFive P550 Premier board running Arch Linux. The kernel source code is available at https://github.com/sifive/riscv-linux using the branch dev/sholland/hifive-premier-p550-amdgpu. The configuration is based on the configuration that ships with the default OpenEmbedded image but enhanced to support zstd and xz initramfs and firmware images for broad OS compatibility. This also enables the radeon, amdgpu, and nouveau drivers. The patches to enable the I2C interface on the 40pin GPIO header are also included. There are also additional filesystems enabled (xfs, btrfs) as modules. Use of an initramfs is strongly recommended.

Notes on video support

This kernel do not enable the Integrated Display Controller and GPU (iGPU) and is specifically designed for use with an Dedicate GPU in the PCI-express slot (dGPU). If your goal is to use a Integrated Display Controller and GPU (iGPU) then I suggest trying the variant of this kernel package at https://github.com/edolnx/linux-edolnx-sifive-p550

Building the Kernel

The kernel can be built natively on the P550 Premier itself, just like any other Arch package. Follow these steps to build the kernel:

$ git clone https://github.com/edolnx/linux-edolnx-sifive-p550-dgpu.git
$ cd linux-edolnx-sifive-p550-dgpu
$ makepkg
