[RFC PATCH 2/5] xen/grants: update initialization order of xen grant table

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The xen grant table will be initialied before parsing the PCI resources,
so xen_alloc_unpopulated_pages() ends up using a range from the PCI
window because Linux hasn't parsed the PCI information yet.

So modify the initialization order to make sure the real PCI resources
are parsed before.
