eDP? That's probably not very helpful to you, I'm sorry.

You can find an example of similar code in src/drivers/lenovo/ > hybrid_graphics/. I'll work on this, then. _______________________________________________ coreboot mailing list -- [email protected] To unsubscribe send an email to [email protected]
