[Xen-ia64-devel] Re: Problem with xen-unstable cset 7937 (grant table tr
That changeset only changes gnttab_transfer, which is used only by
netfront/netback. Since those don't yet build on ia64 I'm not sure how
domU boot has been broken.

It appears that a grant table fix Keir made (cset 7937 in
xen-unstable) has broken Xen/ia64 domU boot. I am getting:
WARNING: g.e. still in use!
WARNING: leaking g.e. and page still in use!
a number of times, leading to "unable to read superblock"
and "Cannot open root device".
As noted in previous discussions, ia64 uses a separate file
for grant_table.c, though there are more similarities than
differences. (This was a development convenience to avoid
adding ifdefs.) So changes to common/grant_table.c -- with
corresponding usage changes in sparse/arch/xen/kernel/gnttab.c,
which *is* a common file between Xen/x86 and Xen/ia64 -- are
likely to break Xen/ia64. Hopefully a fix will just be a matter
of merging Keir's changes from xen/common/grant_table.c into
xen/arch/ia64/xen/grant_table.c, but ideally the ia64 variant
should be merged back into the common file, though it may
take a few ifdefs.
Any volunteers?
Thanks,
Dan
