Message-ID: <200712160342.38771.carlos@strangeworlds.co.uk> (raw)

Actually, a bit of further reading suggests that this is my fault :(
The original ACPI error was quite correct - there is no EC region handler
installed - because the EC handler is only installed for the EC device
(PNP0C09), not WMI (PNP0C14).
Had I read through the EC code earlier I would have spotted that one. So, my
apologies for wasting your time with this.
So, what I need to do is update WMI to install a handler for the
EmbeddedControl region in PNP0C14.
Alexey - I suspect the easiest way would be to make such a handler just call
ec_read & ec_write, and let the EC driver do the real work, rather than
trying to do anything more complicated in WMI?
-Carlos
(Hoping WMI doesn't keep throwing up more "surprises"...)
