Greetings,
I'm currently working on a coreboot port to the hp g7-2247us[1] and am
looking to implement the needed bits to enable smart battery support in
the acpi tables, and am running into a some issues and potential
misunderstandings as to how it should be handled.
Currently I end up with the following message in dmesg:
sbs: probe of ACPI0002:000 failed with error -62
Which is drivers/acpi/sbshc.c:wait_transaction_complete -ETIME; it was
my understanding that the _EC field 0xYYZZ should be the offset of the
EC ram's for the various SMBus stuff and 0xZZ should be the ec _QZZ
query method to handle it (gathered from some macbook acpi tables I've
located online which implement it). I believe the proper hardware is
there for this to work)
Any suggestions or pointers on this would be of great help.
Regards,
Marty
