Subject: Exclusive access to hardware for test purpose
Date: Thu, 28 Oct 2004 23:35:52 +0100 (BST)	[thread overview]
Message-ID: <20041028223552.71331.qmail@web52801.mail.yahoo.com> (raw)

Hi,

Is anyone aware of kernel call which allows a test
tool developer to have exclusive access to PCI adapter
hardware. By exclusive access I mean both
driver as well as kernel should not touch hardware. 

I have been using driver's remove call to simulate the
situation as if adapter has been hot plugged out. And
once my testing is done I call driver's probe
call to put adapter back. But this seems to create a
problem when somehow kernel calls driver's remove
call.

Also If I dont call probe for the removed adapter, on
next reboot machine hangs !

Any information/suggestions please .....

Thanks in advance.

best regards,
Mehul.
