dump MMU translation table for A9 in Linux

mivascu over 5 years ago

Hello,

I would like to know how to read the translation table info for A9 from embedded Linux.

In freeRTOS I have translation_table.S but I do not find anything similar for ARM architecure in linux kernel.

Should I just dump TTBR0/TTBR1 registers?

Thanks,

Mihaita

Thanks for your answer. Do you know at which offset I can read CP15 register(that enables me to read TTBR0) ?

I could not find it in the programming model, the register offset.

Thanks,

Mihaita
