Since we’ve never seen a single benchmark provided by SinoVoip (that must happen for a reason, normally devs are proud that their hardware is fast and try to proove it) I’m really curious how fast the board is.
I had a look into one now available fex file and started laughing:
; B_LV1: core vdd is 1.08v if cpu frequency is (1800Mhz, 2016Mhz]
; B_LV2: core vdd is 1.00v if cpu frequency is (1608Mhz, 1800Mhz]
; B_LV3: core vdd is 0.92v if cpu frequency is (1200Mhz, 1608Mhz]
; B_LV4: core vdd is 0.84v if cpu frequency is ( 0Mhz, 1200Mhz]
; B_LV5: core vdd is 0.84v if cpu frequency is ( 0Mhz, 1200Mhz]
; B_LV6: core vdd is 0.84v if cpu frequency is ( 0Mhz, 1200Mhz]
; B_LV7: core vdd is 0.84v if cpu frequency is ( 0Mhz, 1200Mhz]
; B_LV8: core vdd is 0.84v if cpu frequency is ( 0Mhz, 1200Mhz]
2.0 Ghz @ 1.08v – LOL. Can someone please post the output of
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
dmesg | egrep "ddrfreq|dsm|cpu_freq"
and then set the stuff to maximum, switch off all CPU cores but 4, do an “apt-get install sysbench p7zip-full mbw” and do a little benchmarking:
echo performance >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 2016000000 >/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
for i in 7 6 5 4 ; do echo 0 >/sys/devices/system/cpu/cpu${i}/online ; done
sysbench --test=cpu --cpu-max-prime=20000 run --num-threads=4
7za b
mbw -t0 256 && mbw -t1 256 && mbw -t2 256
I’m really curious what to expect from a Cortex-A7 running above 2.0 GHz with these little tests (maybe just to discover that there’s an internal divider working and that the cores are running with 1 GHz in reality?)
Anyone? I would do it myself but my M3 hasn’t arrived yet.
