According to foreign technology media phoronix, AMD plans to provide more complete support in the Linux ecosystem before launching Zen 5 CPU processors, and is currently actively submitting patches.
The Linux 6.8 system has initially integrated Zen 5 CPU code, and AMD has submitted performance monitoring patches to prepare for the war.
Recently, AMD has once again submitted an initial patch for Zen 5 CPU performance monitoring and perf subsystem events. This follows the release last week of performance monitoring counter documentation for AMD 1Ah series 00h to 0Fh processors (i.e. Zen 5). The patches contain diverse JSON files essential for AMD Zen 5 perf, enabling monitoring events and metrics viewable through the Linux perf tool. Zen 5 core/non-core events, metrics/mappings are basically the same as Zen 4.
The Zen 5 perf patches are up for review on the kernel mailing list. Since these patches only add JSON without risking existing hardware support, it’s uncertain whether they’ll merge into Linux 6.9.
The Zen 5 chip, which is expected to be mass-produced in the third quarter of 2024, is to strengthen AMD’s layout in the AI terminal field and increase its market share in desktops, laptops and servers. To this end, AMD continues to cooperate with TSMC to promote the production and development of Zen 5 chips code-named “Nirvana”.
After AMD launched the MI300 series AI accelerator card, it increased the scale of orders to TSMC, focusing on 3nm, 4nm and 5nm processes. Industry analysts anticipate AMD’s 3nm process Zen 5 architecture to commence mass production in Q2 2024, followed by expanded capacity for large-scale production in Q3.
