Hi, I've been working with 2 drivers, an i2c based touchcreen and a spi based ethernet. My problem comes when I try to change the affinity for their irqs to be handled by processor 2, change is not reflected, for the ethernet I have... # cat /proc/interrupts | grep eth0 194: 4883 0 GPIO eth0 # cat /proc/irq/194/smp_affinity 3 # echo 1 > /proc/irq/194/smp_affinity # cat /proc/irq/194/smp_affinity 3 Is there any flag needed in the irq handler to allow the affinity? I have tested the irq affinity for a keypad driver and it is working as expected... Thanks for your comments...
