More questions about memory

[Alan B. <al...@ms...>]

Hi,

under APUS, what does phys_to_virt operate on?

When doing a phys_to_virt(0x1200) I am getting what appears
to be bogus memory addresses returning...eg stuff in 59xxxxxx

I'm sure that my memory starts at 0x66000000 and that APUS
looks at the execption vectors at 0xfff00000 (the last is certainly
true according to the kernel sources! ;-) )

do we have a value of KERNELBASE or MEM_OFFSET that operate under
APUS?

if phys_to_virt isnt working normally, then what function do I use
to replace

start_val = phys_to_virt(0x1200);

start_val = 0xfff01200;   ??

Thanks if anyone can help....I'm getting worried about no responses from
this list
