Hi,

Is there any way to access the gpu address space? Let us say my gfx card has a total of 1gb of memory. Can I access this entire memory space from the host, right from 0x00000000 to 03FFFFFF?

Sort of like the gpu mem dump.

Short answer: no!

Long answer: it might be possible as GPU Memory is mapped into kernel space, depending on your OS, to access it directly.
