Significance of x in TTBR0 / HTTBR . Cortex A why do we need such detail
in a pointer which points to a table
Pardon my ignorance on this topic. In order to translate VA to PA, you
take first few bits of the VA and take that as an index into a table. This
table is stored at a particular address which has to be aligned and can be
anywhere in 4g space. Now there is a x in TTBR0 and HTTBR. I dont
understand what is the significance of limits and rules on Address where
the table is stored.
Can someone point out a use case where x plays its part
