AMD actively submits Linux performance monitoring patches to prepare for Zen 5 CPU release

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). These patches include various JSON files required by AMD Zen 5 perf for various performance monitoring events and metrics, and can be displayed via the Linux perf tool. Zen 5 core/non-core events, metrics/mappings are basically the same as Zen 4.

These Zen 5 perf patches have been posted on the kernel mailing list for review. Given that these patches only involve JSON additions, with no risk of rolling back existing hardware support, it's unclear if they will be merged 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. According to the observations of industry analysts, AMD's 3nm process Zen 5 architecture is expected to be put into mass production in the second quarter of 2024, and then large-scale mass production will begin in the third quarter after increasing monthly production capacity.
