* ptp: add testptp mask testXabier Marquiegui2023-10-151-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add option to test timestamp event queue mask manipulation in testptp. Option -F allows the user to specify a single channel that will be applied on the mask filter via IOCTL. The test program will maintain the file open until user input is received. This allows checking the effect of the IOCTL in debugfs. eg: Console 1: ``` Channel 12 exclusively enabled. Check on debugfs. Press any key to continue ``` Console 2: ``` 0x00000000 0x00000001 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 ``` Signed-off-by: Xabier Marquiegui <reibax@gmail.com> Suggested-by: Richard Cochran <richardcochran@gmail.com> Suggested-by: Vinicius Costa Gomes <vinicius.gomes@intel.com> Signed-off-by: David S.

* selftests/ptp: Add -X option for testing PTP_SYS_OFFSET_PRECISEAlex Maftei2023-07-281-1/+30

* ptp: Add .getmaxphase callback to ptp_clock_infoRahul Rameshbabu2023-06-201-2/+4
| | | | | | | | | | | | | | | | | Enables advertisement of the maximum offset supported by the phase control functionality of PHCs. The callback is used to return an error if an offset not supported by the PHC is used in ADJ_OFFSET. The ioctls PTP_CLOCK_GETCAPS and PTP_CLOCK_GETCAPS2 now advertise the maximum offset a PHC's phase control functionality is capable of supporting. Introduce new sysfs node, max_phase_adjustment.

* selftests/ptp: Fix timestamp printf format for PTP_SYS_OFFSETAlex Maftei2023-06-151-3/+3
| | | | | | | | | | | | | | | | | Previously, timestamps were printed using "%lld.%u" which is incorrect for nanosecond values lower than 100,000,000 as they're fractional digits, therefore leading zeros are meaningful. This patch changes the format strings to "%lld.%09u" in order to add leading zeros to the nanosecond value.

* testptp: add option to shift clock by nanosecondsMaciek Machnikowski2022-02-221-4/+14
| | | | | | | | | | | | | Add option to shift the clock by a specified number of nanoseconds. The new argument -n will specify the number of nanoseconds to add to the ptp clock. Since the API doesn't support negative shifts those needs to be calculated by subtracting full seconds and adding a nanosecond offset.

* testptp: set pin function before other requestsMiroslav Lichvar2022-01-051-12/+12
| | | | | | | | | | | | | | | When the -L option of the testptp utility is specified with other options (e.g. -p to enable PPS output), the user probably wants to apply it to the pin configured by the -L option. Reorder the code to set the pin function before other function requests to avoid confusing users.

* testptp: add new options for perout phase and pulse widthVladimir Oltean2020-07-201-4/+37
| | | | | | | | | | | | | | | | | | | | | | Extend the example program for PTP ancillary functionality with the ability to configure not only the periodic output's period (frequency), but also the phase and duty cycle (pulse width) which were newly introduced. The ioctl level also needs to be updated to the new PTP_PEROUT_REQUEST2, since the original PTP_PEROUT_REQUEST doesn't support this functionality. For an in-tree testing program, not having explicit backwards compatibility is fine, as it should always be tested with the current kernel headers and sources.

In addition it will probably never make sense to implement this functionality. This patch removes the misleading example code which seems to suggest that posix timers for PHC devices will ever be a thing.
