* cmd_dhry.c: Use lldiv for vax_mips calculation as wellTom Rini2016-03-171-1/+1
| | | | | | | | | | Since dhry_per_sec is a u64 we must also use lldiv here when working with it. Otherwise: ../lib/dhry/cmd_dhry.c:(.text.do_dhry+0xd8): undefined reference to `__udivdi3' On some platforms. Signed-off-by: Tom Rini <trini@konsulko.com>
* dhry: Correct dhrystone calculation for fast machinesSimon Glass2016-03-171-3/+5
| | | | | | | At present samus reports about 5600 DMIPS. With the default iteration count this is OK, but if 10 million runs are performed it overflows. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add a dhrystone benchmark commandSimon Glass2015-07-211-0/+34
Drystone provides a convenient sanity check that the CPU is running at full speed. Add this as a command which can be enabled as needed. Note: I investigated using Coremark for this but there was a license agreement and I could not work out if it was GPL-compatible. Signed-off-by: Simon Glass <sjg@chromium.org>
