During the testing of the 1-1 mapping with PV guests (so PCI passthrough with "Patches for PCI passthrough with modified E820: http://lists.xensource.com/archives/html/xen-devel/2011-04/msg00574.html) I discovered some bugs in the way the E820 setup code works and as well when we create the P2M parallel data structures to contain the MFNs of the P2M pages (so p2m_top_mfn_p and p2m_top_mfn). The patches are located in git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git devel/p2m-e820-pci.v2 The diffstat: arch/x86/xen/p2m.c | 30 ++++++++++++++++++++++++++++-- arch/x86/xen/setup.c | 2 +- 2 files changed, 29 insertions(+), 3 deletions(-)
