mic clock running at slower frequency

[kvs]

Hi All, My phi card does not seem to be running at its fastest clock Can anyone shed some light what might be happening. It looks like max scaling freq is set to 1238094 whereas it should have been 1333332. Any suggestion how this can be set correctly. ~ # cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 1238094 ~ # cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq 1333332 ~ # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 619047 666666 714285 761904 857142 952380 1047618 1142856 1238094 1333332 ~ # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 1238094 ~ # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 619047 ~ # echo 1333332 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq ~ # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 1238094 ~ # cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state 619047 0 666666 0 714285 0 761904 0 857142 0 952380 0 1047618 0 1142856 0 1238094 181873382 1333332 0 MicInfo Utility Log Created Fri Jan 3 17:42:40 2014 System Info HOST OS : Linux OS Version : 2.6.32-358.el6.x86_64 Driver Version : 6720-19 MPSS Version : 2.1.6720-19 Host Physical Memory : 32847 MB Device No: 0, Device Name: mic0 Version Flash Version : 2.1.03.0386 SMC Firmware Version : 1.15.4830 SMC Boot Loader Version : 1.8.4326 uOS Version : 2.6.38.8-gefd324e Device Serial Number : ADKC32301210 Board Vendor ID : 0x8086 Device ID : 0x225c Subsystem ID : 0x7d95 Coprocessor Stepping ID : 2 PCIe Width : x16 PCIe Speed : 5 GT/s PCIe Max payload size : 256 bytes PCIe Max read req size : 512 bytes Coprocessor Model : 0x01 Coprocessor Model Ext : 0x00 Coprocessor Type : 0x00 Coprocessor Family : 0x0b Coprocessor Family Ext : 0x00 Coprocessor Stepping : C0 Board SKU : C0-7120 P/A/X/D ECC Mode : Enabled SMC HW Revision : Product 300W Passive CS Cores Total No of Active Cores : 61 Voltage : 1024000 uV Frequency : 1238095 kHz Thermal Fan Speed Control : N/A Fan RPM : N/A Fan PWM : N/A Die Temp : 55 C GDDR GDDR Vendor : Samsung GDDR Version : 0x6 GDDR Density : 4096 Mb GDDR Size : 15872 MB GDDR Technology : GDDR5 GDDR Speed : 5.500000 GT/s GDDR Frequency : 2750000 kHz GDDR Voltage : 1501000 uV Thanks kvs

According to the coprocessor datasheet, 1.333 GHz is the Max Turbo Frequency. This frequency can only be reached in Turbo mode. Under normal conditions, the maximum clock frequency is 1.238 GHz. Hence the max scaling frequency has been set accordingly.

Micsmc-gui has a radio Button for turbo

Only certain SKUs (i.e. card versions) have turbo implemented. I think it's 7120P.

To set turbo and other settings, you need to be privileged.
