Subject: missing set_gpfn_from_mfn in XENMEM_add_to_physmap/XENMAPSPACE_gmfn for xenpaging
Date: Wed, 13 Oct 2010 16:27:40 +0200	[thread overview]
Message-ID: <20101013142740.GA10265@aepfle.de> (raw)


Hello,

while starting xenpaging early from the python code, I ran into the
ASSERT in guest_physmap_remove_page -> p2m_remove_page, called from
arch_memory_op with op==XENMEM_add_to_physmap,
xatp.space==XENMAPSPACE_gmfn. Its called from the hvmloader code.

For some reason the mfn passed to get_gpfn_from_mfn() is different than
the one returned from ->get_entry() in p2m_remove_page().

Any idea where the missing set_gpfn_from_mfn has to be added for a just
paged-in page?


Olaf
