Subject: [PATCH V10 00/15] ptp: IEEE 1588 hardware clock support
Here is version 10 of the PHC patch series. We missed the boat for
2.6.38, but I hope this can be merged for the next one.
Reviewers: I think its done. How can I get this merged?
Arch maintainers (arm, blackfin, powerpc, x86): I have added you on
CC in the hope of getting your acks for the new syscall.
Thanks,
Richard
* Patch ChangeLog
** v10
*** posix clocks
- removed the (previously implied) default functions from the k_clocks
- made the ts parameter 'const' in clock_set functions
*** ptp hardware clocks
- updated to changed PPS kernel API
* Introduction
The aim of this patch set is to add support for PTP Hardware Clocks
(PHCs) into the Linux kernel.
The first eleven patches provide infrastructure supporting dynamic
POSIX clock devices. This new code will be useful for other kinds of
new clocks, not just PHCs.
The last four patches implement the PHC code.
Support for obtaining timestamps from a PHC already exists via the
SO_TIMESTAMPING socket option, integrated in kernel version 2.6.30.
This patch set completes the picture by allow user space programs to
adjust the PHC and to control its ancillary features.
* Previous Discussions
This patch set previously appeared on the netdev list. Since V5 of
the character device patch set, the discussion has moved to the
lkml.
