I am using imx8 (octa core processor A53-4 & A72-2 ) board for biodiversity surveillance system based application. But i couldn’t able to find on which task allocation is the core is working on which architecture for task allocation process on octa core processor. So i want your guidance regarding the core architecture task allocation algorithm followed on octa core imx8 processor
blktrace is a tool used for tracing and analyzing I/O operations on block devices such as hard disks, SSDs, and RAID devices. And will not help to find on which task allocation is the core is working on.
Some blktrace manuals:
As per your suggestion used the perf command to check threads per core but unable to find each core power. Also uses perf script -v, --itrace [=p] which is mentioned in your provided link above as a power synthesize power events. Can you guide me how can we check or any tool which can be used to find the core power usage and frequency?
Actually i am working on imx8 power scheduling algorithm but for that first i want to analyze that how can we check the power and frequency of each core along with tasks allocation for better analyzing process.
So during testing, i cannot able to recognize the power and frequency of each core. As per your toradex documentation you have mentioned power of each core. could you please guide me that how can we measure or any tool can be used ?
As I it was already stated in this conversation you can use a lots of Linux tools. Like
Most powerful one is the perf
Unfortunately it’s nor t easy to measure power consumed by each CPU core but you can get a data how many processor cycles was spend by each core. You can also get each CPU frequency info either by cpufreq-info or by using cpufreq_get_policy() function
I apologize if my previous responses seemed unhelpful. Please note that providing guidance on Linux commands and usage is outside the scope of our free support. However, there are many resources available online to learn about Linux commands and usage, including online courses, tutorials, and documentation.
