Cross compiler toolchain

Cross compiling the Linux kernel for PA-RISC is easy nowadays:

Debian

apt install gcc-hppa-linux-gnu gcc-hppa64-linux-gnu

Fedora

yum install gcc-hppa64-linux-gnu gcc-hppa-linux-gnu binutils-hppa64-linux-gnu binutils-hppa-linux-gnu

How to build the kernel

make ARCH=parisc menuconfig
make ARCH=parisc

Before Kernel v5.17 you need to give CROSS_COMPILE= on the command line when cross-compiling, e.g.:

make ARCH=parisc CROSS_COMPILE=hppa64-linux-gnu-   # to build a 32- or 64-bit kernel (depending on the value in the .config file)

Starting with Kernel v5.17 you don’t need to give CROSS_COMPILE= on the command line any longer, just run:

make ARCH=parisc  # to build a 32-bit kernel

or:

make ARCH=parisc64  # to build a 64-bit kernel
