[Qemu-devel] Qemu: write on physical address

[Liaojianwei]

hello,
i would like to write on physical address, so, i use stl_phys 
(phys_addr, xxx) function (in exec.c) to do that.
it seems that write is okay because i can get the data xxx by calling 
ldl_phys (phys_addr) function. however, when i use pmemsave to dump 
physical memory, i cannot find the data xxx in certain physical address.
i was wondering about that, does any can give me an explanation about that.
thank you in advance, thank you.
liao
