Subject: [kvm-unit-tests PATCH v3 6/6] arm64: dump stack on bad exception
Date: Wed, 28 Jun 2023 00:13:55 +0000 [thread overview]
Message-ID: <20230628001356.2706-8-namit@vmware.com> (raw)
In-Reply-To: <20230628001356.2706-1-namit@vmware.com>
From: Nadav Amit <namit@vmware.com>
Upon a bad exception, the stack is rather useful for debugging, splat it
out.
