Subject: [Qemu-devel] [PATCH v2 7/7] net: remove muldiv64()
Date: Wed, 26 Aug 2015 20:05:38 +0200 [thread overview]
Message-ID: <1440612338-5912-8-git-send-email-lvivier@redhat.com> (raw)
In-Reply-To: <1440612338-5912-1-git-send-email-lvivier@redhat.com>
muldiv64() is used to convert nanoseconds to microseconds.
x = muldiv64(qemu_clock_get_ns(..), 1000000, get_ticks_per_sec());
As get_ticks_per_sec() is 10^9, it can be replaced by:
x = qemu_clock_get_us(..);
Signed-off-by: Laurent Vivier <lvivier@redhat.com>

v2: use qemu_clock_get_us() instead of qemu_clock_get_ns()/1000
