Subject: Kernel Profiling a device driver
Date: Wed, 19 Jun 2002 09:13:19 -0400	[thread overview]
Message-ID: <3D10836F.33E42F14@voicenet.com> (raw)
In-Reply-To: <pan.2002.05.16.14.10.05.542669.21313@sysk-net.com>

on my laptop i have a xircom 100 credit kard pcmcia device.

Unfortunately, at 100mbps, the system time goes up to nearly 100% usage.
( the on-board ethernet at 100mbps gets around 25% system usage )

Is there a way to profile the device driver so that i can zero in on the
section of code that may be spinning, doing inefficient things ?
