sys/dev/if_ndis if_ndis.c if_ndisvar.h
Log:
Modify if_ndis.c so that the MiniportISR function runs in ndis_intr()
and MiniportHandleInterrupt() is fired off later via a task queue in
ndis_intrtask(). This more accurately follows the NDIS interrupt handling
model, where the ISR does a minimal amount of work in interrupt context
and the handler is defered and run at a lower priority.
Create a separate ndis_intrmtx mutex just for the guarding the ISR.
Modify NdisSynchronizeWithInterrupt() to aquire the ndis_intrmtx
mutex before invoking the synchronized procedure. (The purpose of
this function is to provide mutual exclusion for code that shares
variables with the ISR.)
Modify NdisMRegisterInterrupt() to save a pointer to the miniport
block in the ndis_miniport_interrupt structure so that
NdisSynchronizeWithInterrupt() can grab it later and derive
ndis_intrmtx from it.
