Subject: [PATCH 1/2] vdso.7: Remove outdated limitation for powerpc
Date: Sat, 3 Jul 2021 19:26:03 +0200 [thread overview]
Message-ID: <20210703172604.79658-1-alx.manpages@gmail.com> (raw)
Christophe Leroy via Bugzilla:
[
https://man7.org/linux/man-pages/man7/vdso.7.html
(as of today, flagged 2021-03-22)
ppc/32 and ppc/64 sections both have the following note:
The CLOCK_REALTIME_COARSE and CLOCK_MONOTONIC_COARSE clocks
are not supported by the __kernel_clock_getres and
__kernel_clock_gettime interfaces; the kernel falls back to
the real system call
This note has been wrong from quite some time now,
since commit 654abc69ef2e
("powerpc/vdso32: Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE")
and commit 5c929885f1bb
("powerpc/vdso64: Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE")
]
