How to disable L2 Cache?

(Farzad Farshchi) #1

Is it possible to disable L2 cache so that all the memory accesses go to the DRAM? It’ll be more desirable to do it without having to modify the boot-loader.

No. You can restrict the amount of L2 down to direct-mapped 128kB, but if you do that, it also affects the L1 because the L2 is inclusive.
