Linux kernel source for SoC FPGA Intel

[ihsan28]

Hi,

I notice that there are two sources for building a Linux kernel for SoC FPGA. First is https://github.com/altera-fpga/linux-socfpga, and the second is https://github.com/altera-fpga/gsrd-socfpga . Could anyone give an easy explanation about the differences? And when should I use one of those?

Thank you.

The first one looks like straight Linux while the second includes the GSRD to configure the FPGA and HPS for running Linux on particular dev kits.  You can use either.  The second one obviously works best with dev kits and is more complete but can also be used as a starting point for building a hardware design for a custom board.

Hi @ihsan28 ,

The first (linux-socfpga) is the actual Linux kernel source for SoC FPGA devices.

The second (gsrd-socfpga) is a set of metadata and scripts to build a Yocto based Linux distribution for a given devkit (i.e. an image you can use to boot a board).

If you just want to build a Linux kernel from source the first repo is enough. If you want to build a full Linux image for a devkit use the second.
