Subject: How to mmap xen pages?
Date: Fri, 17 Sep 2004 15:32:47 -0600	[thread overview]
Message-ID: <414B57FF.8010109@hp.com> (raw)
In-Reply-To: <E1C8Dim-00079B-00@mta1.cl.cam.ac.uk>

I am try to convey a large data collection buffer from xen to a 
userspace program running in domain 0. I examined the xentrace facility 
and copied the code to mmap pages. My mmap fails, and upon trying out 
the xentrace program, I found that it fails in exactly the same way, ie, 
returns errno 11, "Resource Temporarily Unavailable". I have allocated 
my memory buffers just like common/trace.c does it, etc. Is this trace 
stuff not working anymore, did it ever work, and/or what is the 
recommended way to do what I want?

Thanks,

Rob Gardner
