What is ESEL in TLB ?

[vinothkumars]

Hi All,

I am doing u-boot debugging in T4160RDB target.

disable_tlb(14);

disable_tlb(15);

14 and 15 are ESEL (Entry Select) parameter.

What is entry select (ESEL) ?

How ESEL related with MMU TLB ?

Regards,

It is a part of the chip's memory-management unit. The TLB stores the recent translations of virtual memory to physical memory and can be called an address-translation cache shareit apk.

These are specific entries numbers in the selected TLB array.
