RFC: Output ACPI info via sysfs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently, after booting a system there is no way to tell what hardware is currently in the system. The current output from sysfs only indicates what knowledge the kernel has of the system (ie, is limited by NR_CPUS, etc.). However, during ACPI initialization a lot of data is output to the console about the precise number of CPUs, lapics, etc.

Having this information is useful to anyone (or any application) interested in querying the real system information.

Any thoughts, concerns? (Code not yet generated -- just looking for an okay on the RFC)
