Subject: [v2 0/4] xen/arm: Enable USBAN support
Date: Thu, 29 Jun 2023 21:11:25 +0100 [thread overview]
Message-ID: <20230629201129.12934-1-julien@xen.org> (raw)
From: Julien Grall <jgrall@amazon.com>
Hi all,
At the moment, we are not able to enable UBSAN on Arm because the
final binary will be over the maximum size of Xen we currently support
(i.e. 2MB).
This patch series aim to lift the restrictions and also
enable UBSAN.
Cheers,
Julien Grall (4):
