If present, indicates that the hardware supports stashing buffer descriptors in the L2. The interpretation of time values for these clocks is unspecified. This property is only really needed if the connection is of type “rgmii-id”, as all other connection types are detected by hardware.

[PATCH,v3 1/3] doc: dt: Update eTSEC bindings doc

Arcturus also appears to offer an optional enclosure for the Hostboard. Article Here is the sixth linnux of my patch set adding PTP hardware clock support to the Linux kernel. The last five add the new PTP hardware clock features. Added a clock driver for the IXP46x.

[3/3] gianfar: Implement workaround for eTSEC-A erratum – Patchwork

I want to know what files i should change in order for linux to work in this new condition. For each device that exists on this bus, a child node should be created.

Implement the functionality anew. In reference board one eTSEC is connected to a phy and another is connected to a gigabit ethernet switch.


Arcturus now offers a variety of embedded COMs and integrated systems for VoIP gateways and general industrial applications. The system also ships with a kit including a Hostboard carrier board, as well as schematics and extensive documentation. In the current patch set the kernel functionality is not implemented, since there are some issues to consider first. Previously, I had tried to present the posix clock changes all by themselves, but commentators asked to see the whole context.

From discussions on the lkml, a repeated wish was to ensure that any changes in the POSIX clock code would be general enough to support other new hardware clocks that might appear in the future, not just the particulars of PHCs.

The PHC can be synchronized to within nanoseconds of an external time source, while timer wakeup latency even with rt kernels is tens of microseconds.

Etswc information may be found at the Arcturus Networks uCP product page. IEEE hardware clock support. Linux is a registered trademark of Linus Torvalds. This patch set completes the picture by allow user space programs to adjust the PHC and to control its ancillary features. The Linux BSP, development kit, and demo software, are pre-installed on the module along with Arcturus Management Middleware for remote etec and other duties. Later, the company made reference designs for Renesas SuperH processors, among etesc products.

Time stamp external eteec 2. The ability to directly tune linhx PHC is essential to reap the benefit of hardware timestamping. PowerPC still plays a large role in networking and industrial equipment, but the rtsec has shifted toward ARM and MIPS based systems, which for the most part, also typically run Linux.


[PATCH 6/8] ptp: Added a clock that uses the eTSEC found on the MPC85xx.

I don’t mind leaving both ways in, either. Other interfaces include USB 2.

The main difference to v5 is that the character device interface has been replaced with one based on the posix clock system calls. By adding one additional mode flag to the struct timex, the requirements linjx PHCs are also satisfied. The package includes installation support and access to a dedicated support site.

Linuc, the idea of generating a clock id dynamically seems to have gained acceptance. At this point I am not optimistic about either approach, and I would vote for postponing the timer issue indefinitely.

Offset and length of the register set for the device lijux interrupts: Perhaps one could associate an event device with a hrtimer via the timer itself.
