H A D | hwprobe.h | diff 16252e018a30486eedcfec81fc313445cac25bea Mon Jun 19 23:34:40 CEST 2023 Palmer Dabbelt <palmer@rivosinc.com> Merge patch series "RISC-V: Export Zba, Zbb to usermode via hwprobe"
Evan Green <evan@rivosinc.com> says:
This change detects the presence of Zba, Zbb, and Zbs extensions and exports them per-hart to userspace via the hwprobe mechanism. Glibc can then use these in setting up hwcaps-based library search paths.
There's a little bit of extra housekeeping here: the first change adds Zba and Zbs to the set of extensions the kernel recognizes, and the second change starts tracking ISA features per-hart (in addition to the ANDed mask of features across all harts which the kernel uses to make decisions). Now that we track the ISA information per-hart, we could even fix up /proc/cpuinfo to accurately report extension per-hart, though I've left that out of this series for now.
