Hi,
It is my understanding that in ARM, the MMU setting for
kernel VA range ( 0xc0000000 onwards )
is set up using the section-sized mapping ( 1 Mb in size ) , as this
range maps to a contiguous physical address range.
I am trying out a memory-checking tool on Cortex. This tool has the
requirement that it needs to be able to set up PTE for each 4 Kb
range of kernel address.
So, paging_init ( arch/arm/mm/mmu.c ) is modified for this.
But , with this MMU setting, the kernel hangs somewhere after
freeing init memory. ( "freeing init mem" is the last print I see on
console. )
For 3-level page-table setting of kernel VA, do I have to change
something else also ?
thanks
