[Xen-devel] frame_table initialisation

[PUCCETTI Armand <armand.puccetti@xxxxxx>]

It is unclear for me how variable frame_table is initialised:

1. According to function __start_xen:
Variable frame_table is initialised by __start_xen -> init_frametable.

but

2. some lines before in __start_xen, this variable is referenced by 
function map_pages_to_xen -> virt_to_xen_l2 -> alloc_xen_pagetable -> 
mfn_to_page.
What should the value of frame_table be there?

Do I miss some pre-initialisation(s)?

Armand
