LINUX ETSEC DRIVER DOWNLOAD

A user space application can read the PPS events and tune the system clock, just like when using other external time sources like radio clocks or GPS. Thu, 23 Sep Added a brand new class driver for ptp clocks. Added a simulated PTP hardware clock.

If TBIPA register is not specified, the driver will attempt to infer it from the register set specified your mileage may vary. Adjust clock frequency – Ancillary clock features 1.

If you have the DP and want to try the driver, you need to add this one line to your MAC driver: The advantage of this approach would be that it obviates the need for synchronization wtsec the PHC is selected as the system timer.

The first three patches add necessary background support in the posix clock code. Article Here is the sixth version of my patch set adding PTP hardware clock support to the Linux kernel. The general idea is to advertise the available clock ids to user space via sysfs.

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. PowerPC still plays a large role in networking and industrial equipment, but the segment has shifted toward ARM and MIPS based systems, which for the most part, also typically run Linux.

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

I see two ways to do about this. Email Required, but never shown. This property is only really needed if the connection is linuxx type “rgmii-id”, as all other connection types are detected by hardware.

The package includes installation support and access to a dedicated support site. Both approaches adequately cover the needed functionality, in my opinion. Shift the clock by a given offset atomically 4.

Linux source code: Documentation/devicetree/bindings/net/ (v) – Bootlin

Enable Linux PPS subsystem events 3. The COM and Hostboard are part of a development kit that also includes a power supply, cables, and more. This type of product is typically targeted towards commercial and military customers.

Linux BSP with 3.

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

This is an advanced etsrc management capability allowing certain packet types user defined by filer rules to wake up the system. An implementation may also support additional clocks.

This patch set completes tesec picture by allow user space programs to adjust the PHC and to control its ancillary features. One shot or periodic alarms, with CPU interrupt The patch set includes examples of the first two ancillary features, and implementing the third point for a particular PHC is fairly straightforward.

  AMD MODEL B276 DRIVER

Since the hrtimer code uses a clock event device under the hood, it might be possible in theory to etsc capable PHCs as clock event devices. IEEE hardware clock support Date: These buses are defined similarly to the mdio buses, except they are compatible with “fsl,gianfar-tbi”. We want to change the vitesse switch on mpcerdb with a ks switch. If present, indicates that the hardware supports stashing buffer descriptors in the L2.

Periodic output signals 4. As to other possible clock ids, the standard offers the following hint: Perhaps one could associate an event device with a hrtimer via the timer itself. The fourth point is discussed below. Denotes the number of bytes of a received buffer to stash in the L2. 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.

Expansion is handled via dual PCIe lanes.
