While Intel's GPU compute stack for Linux is fully open-source, one area where it still has room for improvement is getting it packaged up on more Linux distributions. The reference binaries published by Intel for their Compute-Runtime and Level Zero components are just Debian/Ubuntu packages but with time -- and as Arc Graphics and other hardware becomes available -- we are seeing more distributions taking a stab at offering up their own package builds...

Back in October AMD sent out their initial Zen 4 "znver4" enablement for the GCC compiler. That initial Zen 4 support was since merged for GCC 13 but that initial enablement carried over the cost tables from Zen 3 and didn't do much in the way of tuning but rather just flipping on the new instructions supported by the Ryzen 7000 series and EPYC 9004 series processors. Today there is finally some juicy tuning patches being sent out for GCC...
