Subject: [PATCH v1 0/2] Initialize backend memory objects in parallel
Date: Mon,  8 Jan 2024 09:10:39 -0600	[thread overview]
Message-ID: <20240108151041.529716-1-mark.kanda@oracle.com> (raw)

QEMU initializes preallocated backend memory when parsing the corresponding
objects from the command line. In certain scenarios, such as memory being
preallocated across multiple numa nodes, this approach is not optimal due to
the unnecessary serialization.

This series addresses this issue by initializing the backend memory objects in
parallel.
