I will have to do some approximations using a combination of the processor and

mapped by
the graphics driver. Some of those is real memory, some are registers and
are entirely virtual - there isn't any physical DRAM backing them.
These aren't all the regions exposed by video card, because if multiple
apps write to video card register directly it will lock up hard, freezing
PCIe bus. Instead, this is arbitrated by the kernel driver.
best

etching makes access much faster, so you would read and
write non-critical data there, issue a barrier of some sort and then
trigger by writing to register in non-prefetchable space. This is pure
speculation, read noveau driver to find out.
