other thing I should have told you: tmem will not work on 32-bit hardware

change you suggest below is incorrect... all alloc_xenheap_pages calls need to

Dan~<BR> <BR> The problem in first mail I have found:
in 26 lines of tmem_xen.h: <BR> #define
tmem_alloc_tmemheap_pages(_o) alloc_xenheap_pages(_o,0) have 2 arguments to
function alloc_xenheap_pages,but it should be only 1 argument.
<BR> so, I think it can change as
below:<BR> #define tmem_alloc_tmemheap_pages(_o)
alloc_xenheap_pages(_o)<BR> <BR> best

Ruby --<BR><BR>Thanks for your feedback!<BR><BR>Tmem requires both a

interested in memory allocation method of xen and I have follow your
self-balloon and tmem. After rebuild self-ballooning, I think it's a
good idea of constructing a memory pool which can implemet dynamic
memory allocation and reduce IO paging, then I read your mail list and
you summit slide. It's really good idea and long-term planning of your
tmem.<BR>Now I have some problem of your tmem. For I didn't find readme
of tmem, I didn't know how to use it, that means after I patched
successfully how do I know tmem can work correctly?<BR>Another problem
is how do you test the usage rate of the whole memory? You have said the
tmem pool can full with the whole memory space, but how do you know? Is
it some test bench for you to say that?<BR><BR>Best Wishes!<BR>

--<BR><BR>Tmem is still under active development and I've been focused
on keeping up with xen-unstable. It is difficult to keep active
development synchronized with many versions (of both xen and Linux) but
I have started working on a patch to work with Xen 3.3.1 (not 3.3.0).
Would that work for you? If so, I should have it in a few
days.<BR><BR>Would you mind describing what you are planning to use tmem
