Hi Experts,

When performing the iperf test with the wl12xx modules the process named irq 191 wl12xx consumes the higher percentage of CPU. Is it the ISR handler usage or which makes the huge consumption of the same ?

Hi,

Yes - please see: http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_CPU_Utilization for an estimate on the CPU usage during iPerf test.

Hi Giji Joseph,

Thanks for the prompt response, its of great help.

My query is on the percentage of use by the parameters

29% [irq/207-wl1271]
12% [kworker/u:2]
12% [kworker/0:2]
12% [kworker/u:0]
5% [kworker/u:1]

What these components actually does ? Is there any recommendation or guide on reducing the usage by optimizing ?

Hi,

What interrupt trigger are you using (Level/Edge)?
If you are using level, please see if it helps if you move to Edge trigger.

Please check the platform_quirks value in your board file to change the interrupt trigger.

Hi Joseph Gigi,

Its configured as EDGE Triggered by default.

Hi,

I checked this internally - I think what you get is the most optimized result.
