AMD in 2022 continued its open-source/Linux help embrace with providing good launch-day help on each the CPU and GPU sides with their new merchandise, continued ramping up their Linux help on the consumer facet, and has labored extra on optimizations and different enhancements to their Linux help.
AMD this 12 months loved good launch-day help for his or her new Zen 4 processors each with the Ryzen 7000 collection and EPYC 9004 “Genoa” server processors, continued making refinements to their Linux laptop computer SoC help, and capped off the 12 months by having RDNA3 help in place for the Radeon RX 7900 collection launch earlier this month. In explicit having the RDNA3 help in place going again to Linux 6.0 was nice in not requiring Linux Git or the like for launch day help, which had been a requirement for among the previous AMD GPU launches.
This 12 months we have seen AMD publish extra open-source code not just for their {hardware} enablement however numerous user-space libraries and different tooling. And we have seen extra fixes from AMD’s rising variety of Linux engineers this 12 months in going again and offering fixes/optimizations for older merchandise that beforehand acquired neglected or lacked the required sources. Among the numerous patch collection volleyed this 12 months by AMD engineers, standing out has been their continued work on the AMD P-State driver and getting that into form for improved energy/effectivity on Linux with that work hopefully culminating in a couple of months with getting Guided Autonomous Mode and EPP merged. AMD’s early work on the Platform Management Framework merged will even be necessary for next-generation wares.
Of course, there may be nonetheless room for enchancment with AMD’s Linux help. The space that continues to face out is their belated new processor help inside the open-source compilers… With the AMD Zen 4 launch their GCC and LLVM Znver4 enablement got here post-launch and nonetheless stays ongoing with LLVM not but having any tuned help for Zen 4 whereas the GCC tuning work simply started touchdown days in the past due to SUSE. Meanwhile that Znver4 help will solely premiere in a couple of months in steady kind with GCC 13 and LLVM 16. Intel in the meantime had their Xeon Sapphire Rapids help in GCC already going again to final 12 months’s steady launch and has added Granite Rapids, Meteor Lake, Sierra Forest, and different next-generation CPU targets to the open-source compilers already.
But past the compiler critique, hopefully in 2023 we’ll see AMD proceed doing a lot of the identical for open-source/Linux help with well timed {hardware} enablement and pushing extra efficiency optimizations. Given the successes of AMD within the knowledge heart and continued Linux-based consumer wins with the likes of the Steam Deck and Tesla in-vehicle infotainment system, hopefully we’ll see AMD in 2023 proceed their Linux hires. If I can dream, it could even be nice to see AMD do extra round Coreboot and open-source firmware.
For wanting again at among the main AMD Linux milestones of 2022, under are the most-viewed articles on the subject for the 12 months:
