Hi Ralf,

I am sorry if it is not clear from my last mail.

What I want to convey is,
"See MIPS Run" explains "window on physical memory (cached)" will start
@ 0x9000_0000_0000_0000.
You can see "See MIPS Run" page under suspect from this link

How ever as you mentioned Linux source defines CAC_BASE

The Linux header file is correct; the cached and uncached regions are swapped in the "See MIPS Run" diagram.

The full MIPS64 memory map is documented in Volume III of the architecture manual which you can download from
