Clock object not created for Raspberry Pi 5 Ethernet interface #9

Closed abower-amd closed 8 months ago

abower-amd commented 8 months ago

On Raspberry Pi 5, the Ethernet interface is correctly enumerated and identified as having an associated PHC device but a corresponding 'clock' object does not get created.

The effect of this is confusion and an inability to use the NIC clock.

This was not previously a problem in testing with a CM4 but it is unconfirmed whether this is a regression or not.

The issue as reported was user error: not setting non_solarflare_nics on.

However, there were errors in sfptpd_clock.c causing sfptpd to interpret system clock information as if it were for a NIC clock and incorrectly refusing to operate with it. Now fixed.

Failure:

2024-03-14 09:14:38.563828: error: clock system: unable to adjust frequency - no phc device
2024-03-14 09:14:38.563837: warning: servo0: failed to adjust clock system, error No such device
2024-03-14 09:14:38.563848: notice: servo0: alarms changed: none -> clock-ctrl-failure

As fixed:

2024-03-16 19:39:42.114315 [servo0:phc0->system], offset: 64.219, freq-adj: -1132.022, in-sync: 1
