Tigran, Peter,
may a firmware package contain a few 'microcode' updates for a specific cpu?
And if so, does each of them provide independent 'errata' fixes? [*]
(or they are just different versions of the same self-consistent/full 'microcode' update and we may need to apply each of them just e.g. because we can't jump from stepping X.1 to X.3 without applying X.2 in between?
if it's [1], then I wonder why only a single 'microcode' update (which has been previously cached in 'uci->mc') is being applied for the case of system-wide resume (apply_microcode_check_cpu()). Don't we need to go through the full cpu_request_microcode() cycle to consider all updates?
TIA,
-- Best regards, Dmitry Adamushko
