Tino Reichardt 48cf170d5a Add PPC cpu feature tests for FreeBSD and Linux ... Add needed cpu feature tests for powerpc architecture. Overview: zfs_altivec_available() - needed by RAID-Z zfs_vsx_available() - needed by BLAKE3 zfs_isa207_available() - needed by SHA2 Part 1 - Userspace - use getauxval() for Linux and elf_aux_info() for FreeBSD - direct including <sys/auxv.h> fails with double definitions - so we self define the needed functions and definitions Part 2 - Kernel space FreeBSD - use exported cpu_features of <powerpc/cpu.h> Part 3 - Kernel space Linux - use cpu_has_feature() function of <asm/cpufeature.h> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: Ryan Moeller <ryan@iXsystems.com> Signed-off-by: Tino Reichardt <milky-zfs@mcmilk.de> Closes #13725		2022-09-16 14:25:53 -07:00
