Subject: Using mini-os ioremap()
Date: Wed, 05 Jan 2011 14:24:55 -0500 [thread overview]
Message-ID: <4D24C587.6060907@jhuapl.edu> (raw)

I'm trying to map some mmio pages into my mini-os domain to use a
hardware device. The device is at address fed40000. I'm calling
ioremap() on this address but its failing, telling me that mfn fed40 is
in ram space. (Its failing the mfn_is_ram() check.)
What am I doing wrong here?
Thanks!
