After more searching and looking in RadeonHD source code, I think that the issue is related to the new AtomBios support.
First it tries to disable the Power Management (Attempting to disable power management
) which fails because AtomBIOS command table 19 does not exist
Then it tries to disable the clock gating (Attempting to %sable clock gating
) which leads to Unusupported SetVoltage Revision
and the function rhdAtomGetVoltage returns ATOM_NOT_IMPLEMENTED. (by the way there is a typo in the error message, it should be Unsupported).
So I guess the problem is that AtomBios does not work with my BIOS as there are several functions that return ATOM_NOT_IMPLEMENTED
. I read somewhere that AtomBIOS is reading the Video BIOS
. Do integrated graphics cards have a separate bios from the system one e.g. RS690?
I am currently having installed on my Laptop the following bios: AMIBIOS 2006, A16 3BAMS Ver. 1.0A. Do you think that upgrading it to a newer version will fix the problem?
Is there any documentation about the supported hardware and Bios versions by AtomBIOS?
P.S. I found online several similar problems, but they were actually finishing in another branch of the function rhdAtomGetVoltage: Not supporting SetVoltage V1 yet
