High cpu usage by interrupts in A20 system
sucotronic replied to sucotronic's topic in TV Boxes's Allwinner CPU Boxes
Wow, that was a very helpful answer, thanks a lot!! With that info I can just blacklist that modules (anyway, I'm not interested in using the ADC functionality of the A20 :P) and now the system shows proper low cpu usage: root@lime:~# cat /etc/modprobe.d/fix.conf blacklist sun4i_gpadc sun4i_gpadc_iio root@lime:~# ps auxk -cpu | head USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.5 26932 5332 ? Ss 00:07 0:07 /sbin/init root 2 0.0 0.0 0 0 ? S 00:07 0:00 [kthreadd] root 3 0.0 0.0 -
I've repurposed an old TV android box with armbian, just using the Olimex based image. It works peferectly, but I'm seeing a constant constant cpu usage by kworkers: root@lime:~# uname -r 4.19.62-sunxi root@lime:~# ps auxk -%cpu | head USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 5740 8.8 0.0 0 0 ?
