Subject: [PATCH 02/27] kernel: Add Monotonic boot time support
Date: Fri, 9 Nov 2018 12:37:05 +0000 [thread overview]
Message-ID: <20181109123730.8743-3-vincenzo.frascino@arm.com> (raw)
In-Reply-To: <20181109123730.8743-1-vincenzo.frascino@arm.com>
Currently, datapage.h has no support for CLOCK_BOOTTIME.
CLOCK_BOOTTIME is identical to CLOCK_MONOTONIC, but includes
any time spent in suspend.
This patch adds monotonic boot time support (btm_nsec) to datapage.h.
