The Linux 6.11-rc2 kernel will be released later today, and until then, there will be "x86/emergency" material to be merged every week. This week's x86/urgent merge includes a deadlock fix for the aperf/mperf driver and a few other fixes. Perhaps most notable is the addition of some unsupported AMD Zen5 CPU models.
AMDLinux code has always treated Zen5 as a 1Ah series processor with model IDs between 0x00 to 0x2f, 0x40 to 0x4f, and 0x70 to 0x7f. But it turns out that the accepted Zen5 model numbers should be 0x60 to 0x7f... so the current Linux kernel (models 96 to 111) does not cover the 0x60 to 0x6F model range.
The current AMD Ryzen AI300 "StrixPoint" processor is the 26 series 36 model, and the upcoming Ryzen 9000 "Granite Ridge" is the 26 series 68 model. Therefore, it is not urgent that the kernel fails to recognize the flaw of the entire Zen5 series, but it can be speculated that the newly expanded series will eventually be released with some additional parts.
So far, Family26 (1Ah) is only available for Zen5 processors, and in some areas, like the LLVMClang compiler, all Family26 processors model 128 or smaller are considered Zen5.
Anyway, today's x86/urgent pull request will be merged ahead of tonight's release of Linux 6.11-rc2, which contains the extended range of AMD Zen5 models.
