Since Linux 5.7, on MIPS, we use AT_BASE_PLATFORM to pass ISA level. The values may be: mips2, mips3, mips4, mips5, mips32, mips32r2, mips32r6, mips64, mips64r2, mips64r6. This behaivor is different with PowerPC. https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=e585b768da111f2c2d413de6214e83bbdfee8f22 Signed-off-by: YunQiang Su <syq@xxxxxxxxxx> --- man3/getauxval.3 | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/man3/getauxval.3 b/man3/getauxval.3 index 456371c6a..518faf5d3 100644 --- a/man3/getauxval.3 +++ b/man3/getauxval.3 @@ -60,9 +60,10 @@ values are present on all architectures.
