Screen capture of kinfocenter on Core i5-1035G1 (10th gen)

Hi Everyone.

Thanks for a very nice port to Fedora 36. I really like Fedora and the KDE combo.

I'm running kinfocenter. I noticed Processors shows upto SSE4.1/SSE4.2 as Supported Instruction Sets. On my Core i5-1035G1 (10th gen), the list of ISA is missing AVX, AVX2 and AVX512. It is also missing others interesting ISAs, like AES, SHA, RDRAND, RDSEED, ADX and BMI. But the AVX's are the important ones.

According to /proc/cpuinfo (and cleaned up with grep and fold), here is a list of ISAs for the processor:

    fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush
    dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm

    avx512_vnni avx512_bitalg avx512_vpopcntdq rdpid fsrm md_clear flush_l1d 
    arch_capabilities

I'm guessing some interesting AMD processor ISAs may be missing, too. But I can't test it at the moment.

I attached a screenshot of kinfocenter's device information.
