Subject: PS3: Fix memory hotplug
Date: Tue, 13 May 2008 09:23:22 -0700 [thread overview]
Message-ID: <4829C07A.4040407@am.sony.com> (raw)
A change was made to walk_memory_resource() in commit
4b119e21d0c66c22e8ca03df05d9de623d0eb50f that added a
check of find_lmb(). Add the corresponding lmb_add()
call to ps3_mm_add_memory() so that that check will
succeed.
This fixes the condition where the PS3 boots up with
just the 128 MiB of boot memory.
