Hi Grant

I’d like EBBR to specify  a solution to identify the default serial console out of existing optional indications.

Hi Francois,

This is a good topic. EBBR starts from the assumption that whether ACPI or DT is used for the system description, the data will follow the requirements of the technology. For ACPI I don't think we need to add any language, but it would be worthwhile to require stdout-path is specified in the DT. Do you want to propose some language?

On DT systems , we shall state that /chosen/stdout-path must point to a valid path.

On ACPI, we may get the info form \_SB_.COM0 @ DSDT or specify we will get the info from SPCR table. > Regardless of the method , this is required to just boot and do not have to care about clumsy command lines with early_console or console parameters.

Agree. Mucking with the commandline should not be required.


I like this topic be added to the agenda ?

yes. Can you also add an issue to track this topic please?
