the SMP affinity for th SCSI controller (IRQ 24). Now that we've got the IRQ, we can change the processor affinity. To do this, we'll go into the /proc/irq/24/ directory, and see what the affinity is currently set to: [root@archimedes Documentation]# cat /proc/irq/24/smp_affinit...
Yes, I know that IRQ affinity cannot be set for individual GPIO interrupt. So, I also know that IRQ affinity can be set to the entire GPIO Bank (in this case bank 5). So, could you ask your development team to find out how IRQ affinity can be set to GPIO B...
