Hello,
I run lstopo on my APU A10-7850K (4CPUs + 8 GPUs), they are detected
(see included picture) but the 8 GPUs are detected on the PCI bus, while
they are on the same die as the CPUs and directly share parts of the RAM.
... I don't understand the signification of the numbers PCI 1002:130f
Hello,
That's an interesting question:
Even if the GPU is physically-located inside the die, it is exposed as a
"virtual" PCI device (vendor number 1002 and model number 130f), and
that's how we detect it, and that's how the driver configures it. Many
components of the CPU die are configured
