Merge patch series "RISC-V: Detect and report speed of unaligned vector accesses"
Charlie Jenkins <charlie@rivosinc.com> says:
Adds support for detecting and reporting the speed of unaligned vector
accesses on RISC-V CPUs. Adds vec_misaligned_speed key to the hwprobe
adds Zicclsm to cpufeature and fixes the check for scalar unaligned
emulated all CPUs. The vec_misaligned_speed key keeps the same format
as the scalar unaligned access speed key.
This set does not emulate unaligned vector accesses on CPUs that do not
support them. Only reports if userspace can run them and speed of
unaligned vector accesses if supported.
* b4-shazam-merge:
RISC-V: hwprobe: Document unaligned vector perf key
RISC-V: Report vector unaligned access speed hwprobe
RISC-V: Detect unaligned vector accesses supported
RISC-V: Replace RISCV_MISALIGNED with RISCV_SCALAR_MISALIGNED
RISC-V: Scalar unaligned access emulated on hotplug CPUs
RISC-V: Check scalar unaligned access on all CPUs
