Hi Marcin, What a great idea!
Interesting for me as I was just working on a bug where VFP stopped being reported to userspace for aarch32 mode in v6.1-rcs due to a rework in the kernel. That re-work happened in https://lore.kernel.org/all/20220909165938.3931307-2-james.mo...@arm.com and the fix for aarch32 being reported incorrectly went in here https://lore.kernel.org/linux-arm-kernel/20221103082232.19189-1-amit.kach...@arm.com/ But in short it may also be useful to capture the kernel version you tested in the table, as what is reported to userspace could change a bit especially with the latest v6.1 kernel. I wonder also if capturing aarch32 features for each SoC is also worthwhile? You can use getauxval(AT_HWCAP2) api for that. See this link for more info https://community.arm.com/arm-community-blogs/b/operating-systems-blog/posts/runtime-detection-of-cpu-features-on-an-armv8-a-cpu regards, Peter.
