Xeon Phi support removed in GCC 15 compiler

Last week I wrote about Intel aiming to remove Xeon Phi support in GCC 15 with the products being end-of-life and deprecated in GCC 14. While some openly wondered whether the open-source community would allow it given the Xeon Phi accelerators were available to buy just a few years ago and at some very low prices going back years so some potentially finding use still out of them especially during this AI boom (and still readily available to buy used for around ~$50 USD), today the Intel Xeon Phi support was indeed removed.

Xeon Phi PCIe cards are incredibly cheap on eBay, and every now and then my mouse hovers over the buy button – but I always realise just in time that the cards have become quite difficult to use, since support for them, already sparse to begin with, is only getting worse by the day. Support for them was already removed in Linux 5.10, and now GCC is pulling he plug too, so the only option is to keep using old kernels, or pass the card on to a VM running an older Linux kernel version, which is a lot of headache for what is essentially a weird toy for nerds at this point.

GCC 15 will also, sadly, remove support for Itanium, which, as I’ve said before, is a huge disgrace and a grave mistake. Itanium is the future, and will stomp all over crappy architectures like x86 and ARM. With this deprecation, GCC relegates itself to the dustbin of history.
