Hi there,

I've compiled kernel with switcheroo enabled, but can't see those debugfs 
entries. Diggigng around I can't get where those calls of switcheroo are 
called from. Is it firmware image to trigger those calls? And does it mean
only that combination of vga adapters/drivers/firmware will be compatible 
with switcheroo?

Some details:
