Bug ID: 213419
Summary: Outdated limitation for powerpc in vdso(7)
Product: Documentation
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P1
Component: man-pages
Assignee: documentation_man-pages@kernel-bugs.osdl.org
Reporter: christophe.leroy@csgroup.eu
Regression: No
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")
