Subject: [PATCH v2 0/2] Address issues slowing memory init
Date: Wed, 05 Sep 2018 14:13:22 -0700 [thread overview]
Message-ID: <20180905211041.3286.19083.stgit@localhost.localdomain> (raw)
This patch series is meant to address some issues I consider to be
low-hanging fruit in regards to memory initialization optimization.
With these two changes I am able to cut the hot-plug memory initialization
times in my environment in half.
v2: Added comments about why we are using __SetPageReserved
Added new config and updated approach used for page init poisoning
