Hi,
I am writing a driver for Dom0 to access DomU''s memory and
encounter a problem to operate dom0''s page table. In my implementation,
I
have a pmd entry, which points to a L1 page table(A). Then this L1 page
table(A)''s address is kept, and the same pmd points to another L1 page
table(B) using set_pmd. But, when I use the former L1 page table(A) again
using set_pmd, my code does not work! Also I know xen puts the former L1
page table''e type when the new L1 page table(B) was set. Any other
considerations? How can I operate Dom 0''s process page table correctly?
