Hello there,
In the process of trying to understand the MMU and Paging in QEMU, I
stumbled upon the the following functions in monitor.c
- mem_info() and tlb_info()
Can somebody please tell me what's happenning within these functions -
I can see, though I'm not sure, that the physical memory is read for every
page directory (pgd?) and there is a condition check involving pde (page
directory entry?), some masks, and CR4, and stuff and more reads in an inner
loop. Even if I got this right, I have no clue what else is happenning in
there and _why?_. Can somebody please throw more light on what is happenning
within mem_info() and tlb_info() in monitor.c?
Thanks!
