Make the fault reset interval a per-port configuration parameter. A timeout of 15 seconds is not always acceptable, make it configurable. By popular consensus, instead of using a linear number of seconds, use the 2^N format for the time interval, just like the other intervals in the PTP data sets. In addition to numeric values, let the configuration file support 'ASAP' to have the fault reset immediately. [RC - moved the handling of special case tmo=0 and added a break out of the fd event loop in case the fds have been closed. - changed the linear seconds option to log second instead. - changed the commit message to reflect the final version. ] Signed-off-by: Delio Brignoli <dbrignoli@audioscience.com> Signed-off-by: Richard Cochran <richardcochran@gmail.com>

Support hybrid E2E using unicast delay requests and responses. The draft Enterprise Profile [1] specifies a hybrid E2E delay mechanism, where the delay response message is sent "in kind". That is, if the request is unicast, then the response is also unicast. Apparently this scheme is already in widespread use in some industries. Also, it makes sense, because those messages are of no interest to the other slaves in the PTP network. Because of the address work already in place, in turns out that adding this mode is almost trivial. This patch introduces an "hybrid_e2e" option that enabled the new mode. 1. https://datatracker.ietf.org/doc/draft-ietf-tictoc-ptp-enterprise-profile Signed-off-by: Richard Cochran <richardcochran@gmail.com>

ptp4l: Use poll() instead of a try-again loop This patch modifies sk_receive in order to use poll() on POLLERR instead of the tryagain loop as this resolves issues with drivers who do not return timestamps quickly enough. It also resolves the issue of wasting time repeating every microsecond. It lets the kernel sleep our application until the data or timeout arrives. This change also replaces the old tx_timestamp_retries config value with tx_timestamp_timeout specified in milliseconds (the smallest length of time poll accepts). This does have the side effect of increasing the minimum delay before missing a timestamp by up to 1ms, but the poll should return sooner in the normal case where a packet timestamp was not dropped. This change vastly improves some devices and cleans the code up by simplifying a race condition window due to drivers returning tx timestamp on the error queue. [ RC - removed the unused 'try_again' variable. ] Signed-off-by: Jacob Keller <jacob.e.keller@intel.com>

pi_proportional_const 0.0
pi_integral_const 0.0
Adjust constants of PI servo according to sync interval. Instead of using fixed constants, set them by the following formula from the current sync to allow good performance of the servo even when the sync interval changes in runtime and to avoid instability. kp = min(kp_scale * sync^kp_exponent, kp_norm_max / sync) ki = min(ki_scale * sync^ki_exponent, ki_norm_max / sync) The scale, exponent and norm_max constants are configurable. The defaults are chosen so there is no change to the previous default constants of the servo with one second sync interval. The automatic adjustment can be disabled by setting the pi_proportional_const and pi_integral_const options to a non-zero value, but stability of the servo is always enforced.

step_threshold 0.0
Increase default first step threshold to 20 us. Most PHC drivers implement stepping (ADJ_SETOFFSET) by reading the clock, adjusting the value by the offset and writing it back. This is not perfectly accurate and if the operation is slow (e.g. due to PCIe latencies), the error can be in microseconds. Increase the default first step threshold from 100 nanoseconds to 20 microseconds to step only when the initial offset is larger than the error in the step.

clock_servo pi
Add clock sanity check. Check the sanity of the synchronized clock by comparing its uncorrected frequency with the system monotonic clock. When the measured frequency offset is larger than the value of the sanity_freq_limit option (20% by default), a warning message will be printed and the servo will be reset. Setting the option to zero disables the check. This is useful to detect when the clock is broken or adjusted by another program. Signed-off-by: Miroslav Lichvar <mlichvar@redhat.com>

tsproc: add raw and weighting modes. Add new time stamp processing modes to return raw delay and offset based on the raw delay instead of the long-term filtered delay, and to return also a weight of the sample. The weight is set to the ratio between the two delays.
