Invalid entry - mmu page tables

Ryan100

Hi,

I'm pretty much new to this. I have Level 2 table (for ARMv8 - 64KB granule) with multiple 512MB block entries inside.
Some of those blocks are not valid (belong to the reserved/not accessible memory).

Instead of them I've put INVALID entry with descriptor: 0x0000000000000002
Problem is that when this invalid entry is hit (mis-predicted), VA address is translated to PA = 0x0 and cpu will try to read from 0x0.
I thought it will dismiss this translation.

Is there a way to declare this invalid entry to dismiss/not translate this address when it is hit?

Thanks
