Subject: Looking for a way to trigger error on network adapter
Date: Wed, 21 Feb 2001 14:45:22 +0100 [thread overview]
Message-ID: <20010221144521.A18673@se1.cogenit.fr> (raw)
Hello,
Context:
HDLC PCI adapter + line at 2 Mb/s + external traffic generator that fills
the line with 5 to x1000 bytes frame.
I want to see how my code bahaves during rare (?) events: an overflow of
the RX fifo (256 bytes) and a TX underrun. It's my understanding that if the
adapter pains at DMAing, those errors should be triggered.
Could I/O at a inocuous location (a well-choosen PCI register ?) be enough
for that ?
