Date: Wed, 14 Jan 1998 08:57:40 -0600 [thread overview]
Message-ID: <19980114145740.ESdkrV66BIlUL56Fqxu3dGdSho2pa7om5vUyRsuwI_8@z> (raw)
Some further questions.
How do I abort a command?
If a driver needs to time out on a command and reclaim the
memory, how do I tell the DPT that not only am I not interested
in command anymore, but if it returns with the address of
a ccb the driver has reused, bad things will happen.
If there is a way to abort the command to the adapter,
how long does it wait for the queued command to come back
from the target? What happens if that is not long enough?
Or does the adapter tell the target to abort the queued
operation?
In my Adaptec 154x driver, I send a ccb abort message and the
controller acknowledges it before I reuse the memory.
Is there a current technical reference manual?
