Subject: [Qemu-devel] [PATCH v1 0/2] memory: fix alignment checks/asserts
Date: Thu, 7 Jun 2018 17:47:03 +0200 [thread overview]
Message-ID: <20180607154705.6316-1-david@redhat.com> (raw)
We can currently hit two asserts. Let's fix those.
Patch nr. 1 is a result from:
"[PATCH v4 00/14] MemoryDevice: use multi stage hotplug handlers"
We treat right now any alignment > 1GB as a violation, as it would
fragment guest memory heavily. Turn the assert into a check.
Also, we run into an assert when using alignments that are not a power of
two.
David Hildenbrand (2):
memory-device: turn alignment assert into check
exec: check that alignment is a power of two
