Charlie Jenkins <charlie@rivosinc.com> says: All extensions, both standard and vendor, live in one struct "riscv_isa_ext". There is currently one vendor extension, xandespmu, but it is likely that more vendor extensions will be added to the kernel in the future. As more vendor extensions (and standard extensions) are added, riscv_isa_ext will become more bloated with a mix of vendor and standard extensions. This also allows each vendor to be conditionally enabled through Kconfig. * b4-shazam-merge: riscv: cpufeature: Extract common elements from extension checking riscv: Introduce vendor variants of extension helpers riscv: Add vendor extensions to /proc/cpuinfo riscv: Extend cpufeature.c to detect vendor extensions Link: https://lore.kernel.org/r/20240719-support_vendor_extensions-v3-0-0af7587bbec0@rivosinc.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
