Part Number: DRA72XEVM
Hi teams
using another ID(https://e2e.ti.com/support/processors-group/processors/f/processors-forum/587925/linux-am4379-how-to-change-interrupt-priority-for-ethernet) suggesting "ps -A | grep ksoftirq" to get PID. I can't get other pids except:
9 root 0 SW [ksoftirqd/0]
17 root 0 SW [ksoftirqd/1]
how do I to increase priority of IRQ(number 95 as follows) which is used in cpu0.
root@dra7xx-evm:~# cat /proc/interrupts
CPU0 CPU1
17: 0 0 CBAR 32 Level gp_timer
94: 0 0 WUGEN 132 Level arm-pmu
95: 6053 0 4805b000.gpio 10 Edge gpoi-uart-timesync
160: 0 0 pinctrl 992 Edge 4806a000.serial:wakeup
161: 0 0 4805d000.gpio 27 Edge 4809c000.mmc cd
IPI0: 0 1 CPU wakeup interrupts
I have two question.
1. how to change priority of 95(gpio-uart-timesync), I find the delay-time of IRQ by MCU is about 5ms to 10ms. this difference is unacceptable。
2. Can you give me a plan that change IRQ from cpu0 to cpu1. and increase the priority IRQ.
thanks.
