[PATCH v1 13/25] hw/tricore: Add testdevice for tests in tests/tcg/ |
Date: |
Mon, 19 Apr 2021 15:54:23 +0100 |
From: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>
this device is used to verify the correctness of regression tests by
allowing guests to write their exit status to this device. This is then
used by qemu to exit using the written status.
