Welcome to the linux-ia64 wiki!

This is a project to maintain out-of-tree support for the Itanium architecture in Linux kernel after it was removed in November 2023.

Organization

The code consists of a patchset on top of the current torvalds.git master tree, intended to be merged back into master eventually. There is also a patchset for the current stable kernel in the corresponding branch. Branches created for -rc versions are for reference only and will not be updated with new fixes.

The patchset contains revert patches for ia64 removal as well as fixes of both issues introduced before the removal and after the removal. In the future, it may also include new ia64-specific enhancements and features.

Development and testing

Branch master-revert-ia64-removal is periodically rebased and boot tested on a HP Integrity rx2620 server before being pushed.

Latest version of T2 SDE supports Itanium: https://dl.t2sde.org/binary/2023/t2-23.12-ia64-minimal-desktop-gcc-glibc-itanium2.iso. If you want to build the kernel, you can even use its cross-toolchain to cross-compile it from your favorite fast machine.
