How feasible/reasonable would it be to have linuxbios use ACPI as its
table format?
The ACPI guys seem the listen and respond to feedback, they might even
consider changes to drivers/acpi for linuxbios, if the changes were
generally useful.
And, slight tangent, the general ia32 OS kernel method for probing
memory size(s) is via BIOS INT e820 (or is it e802?). Anyway, it
provides a list of memory ranges, and what type of information that
memory range contains (useable RAM, ACPI table, etc.). Providing e820
info to ia32 OS kernels would be a big step towards providing an easy
way to serve memory info and ACPI tables to all OS's.
