About time spend when processing Dispatch routine?

NTDEV
1

Can someone tell me how long can driver be on a Dispatch_LEVEL, I mean time
in seconds (inside Dispatch routine)? I don’t remeber if I have read this in
DDK.

These are some of the time constraints…

Not more than 50 Microseconds at Device IRQL

Not more than 25 Microseconds while holding any DISPATCH_LEVEL Spinlocks…

Not more than 1 Millisecond at DISPATCH_LEVEL (Dpc routine, startio routine, I/o timer routine, I/o Completion Call backs, AdapterControl Routines…)

IIRC the recommendation is - not more than several timeslices (10ms on
NT4).
