Guys,
I have added IRQ coalescing to sata_mv, but need a way to activate/tune it.
There are two simple parameters: an IRQ count threshold, and a time threshold.
Whenever either the count or the time threshold is exceeded,
the chip will generate an interrupt (assuming at least one completed event).
These two parameters are per-chip (actually, per group of four ports within the chip).
How can I export these for setting/query withing sysfs ?
It is all rather easy to create per-SCSI-host attrs in sysfs,
but I don't see any obvious way to do it per-chip.
Suggestions?
For now, I'm doing it with a module parameter,
but that's really rather stone-age in the sysfs era.
Thanks.
