When is the release of the writeup on how to do this? RAM and GPU prices are skyrocketing
Massive waste of the GPU, having it spend so much time handling PCI. I bet that part of the chip heats up like an MF while the CUs are barely getting tickled.
Is the driver not coded up like an APU?
I expect so, yes, that’s the model for handling SoC GPUs on Windows and Linux: treat it like a PCI peripheral. (Use PCI protocol, even though it’s not a PCI connection.)
This make it spend a lot of time managing PCI book-keeping, which doesn’t scale and becomes a performance bottleneck — but, more importantly, a thermal hotspot.
Console OSes don’t coordinate integrated GPUs over PCI, so they don’t have the same thermal issue.
Edit: I should specify: this is x86. ARM SoC GPUs on Linux at least (Idk about Windows) are not treated as PCI peripherals.
