[PATCH] Documentation, mm/unaccepted: document accept_memory kernel parameter

From: Vlastimil Babka
Date: Tue Dec 12 2023 - 12:21:59 EST


The accept_memory kernel parameter was added in commit dcdfdd40fa82
("mm: Add support for unaccepted memory") but not listed in the
kernel-parameters doc. Add it there.

+ accept_memory= [MM]
+ Format: { eager | lazy }
+ default: lazy
+ By default, unaccepted memory is accepted lazily to
+ avoid prolonged boot at the cost of some runtime
+ overhead until all memory is eventually accepted. In
+ most cases the overhead is negligible but for some
+ workloads or for debugging purposes accept_memory=eager
+ can be used to accept all memory at once during boot.
