Subject: [patch 16/24] virtio_rtc: Use provided clock ID for history snapshot
Date: Tue, 26 May 2026 19:14:47 +0200 [thread overview]
Message-ID: <20260526171223.901103717@kernel.org> (raw)
In-Reply-To: 20260526165826.392227559@kernel.org
The PTP core indicates in system_device_crosststamp::clock_id the clock ID
for which the system time stamp should be taken. That allows to utilize
hardware timestamps with e.g. AUX clocks.
Use ktime_get_snapshot_id() and hand the provided clock ID in.
No functional change.
