Tool/software: Linux
Hi, Everyone
I have a question about RTLinux for AM437x using AM437xSK.
My customer develop for EtherCAT Master using RTLinux.
They want to change interrupt proority.
They see 2 Ethernet interrupt using "cat /proc/interrupts"command.
==
173: 0 WUGEN 41 Level 4a100000.ethernet
174: 0 WUGEN 42 Level 4a100000.ethernet
==
and They looked for SoftIrqHandler of Ethernet using "ps –A | grep irq" command.

but We do not find Ethernet interrupt in SoftIrqHandler.
If we find, I guess we can change priority. but we do not see this interrupt.
Can you tell me how to change Ethernet interrupt priority ?
