Hi All,
I am working with Ninja Developer Platform (NDP) with following specifications:
- Operating System: CentOS Linux 7 (Core)
- Kernel: Linux 3.10.0-514.10.2.el7.x86_64
- Architecture: x86-64 Intel(R) Xeon Phi(TM) CPU 7210 @ 1.30GHz
I have many questions around the system as I wish to run and collect data using command line only. If anyone can help me with following questions, then it will be really helpful.
System:
- Does above system only support performance and powersave governors because of intel_pstate driver?
- Any future plans to support ondemand, interactive, and conservative governors?
- On sysfs interface, I can't find a files/paths where per core utilization is updated. Is it possible to collect per core utilization?
- Is it possible to configure MCDRAM mode (flat, cache, hybird) using sysfs?
- To capture power usage, is this the correct sysfs path: /sys/class/powercap/intel-rapl/intel-rapl\:0/energy_uj ?
- Using sysfs again, how can I change memory power budget?
- What is the cooling device interface at this path: /sys/class/thermal/cooling_device ?
- I couldn't find sysfs entry for reading per core/cluster temperature. Any such path on sysfs?
- Possible to capture power usage separately using sysfs for: core/cluster, memory, and GPU?
- How to find range of frequencies Xeon Phi supports? On sysfs I couldn't find sysfs which list range of frequencies.
- Is there any Intel tool that can profile workload and simulatenously capture system details like: governor, frequency, utilization, temperature, online cores, and performance counters, all via command line?
- What is "uncore_cha_X" interface at /sys/devices ?
Booting:
- Is this the correct link to download kernel and operating system files?
- Since NDP is a dektop host, and not a development board. I want to know if there is a documentation on how to boot NDP via network file system? This way, I don't have to touch default system and kernel files on host, and can quickly test any kernel changes I want to implement.
Thanks.
