Hi,
As I understand it, the only thing missing with regard to nvidia dGPUs on
Coreboot are the ACPI calls to turn them on and off at run-time, which is
what Optimus is. Things like DRI_PRIME and similar work just fine as long
as the dGPU is running, even under nouveau.
What is the current status of the work to get nvidia Optimus working? From
what I gather there have been a couple of attempts and a recent restart,
but I don't know what the current status of this work is.
I have heard that some laptops currently have the option to switch the dGPU
on or off at boot-time. For which ones does this work?
If the work on Optimus is completed, what laptops are most likely to
support it? My expectation is that turning the GPU on or off may be
different for different laptops, even though the ACPI calls are the same,
and so may not work everywhere.
Thanks,
-Matt
