I guess that's a power-saving mode where only the VRAM is powered. That would be the dGPU equivalent of ACPI S3 (the memory contents are preserved, but the rest of the system is powered off). Sounds pretty interesting, as it would provide good power savings at a reduced exit latency :-D

In any case, it would be nice to add this to the commit message:

BOMACO stands for "Bus Off Memory Alive Core Off".
