[XenARM] RE: Strange behaviour...

[ROSSIER Daniel <Daniel.Rossier@xxxxxxxxxx>]

Sorry, the function is setup_pg_tables() and not build_pagetable()….

Hello,

 

Just a question:

The following code is taken from domain_build.c in Samsung's port, in the build_pagetable() function:

 

…

for (count = 0; count < 4; count++) {

                *(pde + count) = l2e_from_paddr((unsigned long)pte, __L2_PAGE_USER_TABLE);

                pte += 256; /* coarse page table on ARM */

        }

…

 

However, the l2e_from_paddr() begins with the following assertion: ASSERT((pa & ~(PADDR_MASK & PAGE_MASK)) == 0);

 

Which will fail since the pte address is incremented with 256 (*4), and is not 4 KB-page aligned.

 

Is the build_pagetable() function not used anymore?

 

Cheers

Daniel
