Which kernel, if any, supports the 36-bit physical addressing
capability (e.g., BATs, page table entries, etc.) of the 7457?
Marvell's GT64360 device has support for 36-bit physical addressing
and it also supports a maximum of 8GB of local memory. Does any
kernel support this amount of local memory?
Thanks in advance.
Curious,
Rob Baxter

Wahaaa haa haa, surely you jest?? :)
The answer, for now, is "no".

I've done some work on it, along with software TLB loading. I never
had a system with memory addressed up there so I couldn't test it.
It's out of date by now, but I could get back to it if there was
some incentive to do so :-)

Why don't you share it with us?
