Subject: [PATCH 1/2] rust: time: expose as_nanos for clock sources.
Date: Mon, 02 Nov 2026 17:17:40 +1000	[thread overview]
Message-ID: <20261102-nova-timer-v1-1-b347ead64469@redhat.com> (raw)
In-Reply-To: <20261102-nova-timer-v1-0-b347ead64469@redhat.com>

From: Dave Airlie <airlied@redhat.com>

The nouveau C driver does ktime_to_ns(ktime_get()) to program
the cpu ns into some hw/fw, so allow this method for rust drivers.
