Subject: [Qemu-devel] [PATCH 0/2] Architectural watchpoint check
Date: Mon, 14 Sep 2015 13:50:49 +0300 [thread overview]
Message-ID: <1442227851-11414-1-git-send-email-serge.fdrv@gmail.com> (raw)
This series is intended to fix ARM watchpoint emulation misbehavior.
QEMU hangs when QEMU watchpoint fires but it does not pass additional
architectural checks in ARM CPU debug exception handler. For details,
please see individual patches. The most relevant parts of the original
discussion about ARM breakpoint and watchpoint emulation misbehavior can be
found at:
