Subject: [PATCH] powerpc/prom_init: Include the termination message in ibm, os-term RTAS call
Date: Tue, 24 Mar 2020 17:12:11 -0300 [thread overview]
Message-ID: <20200324201211.1055236-1-farosas@linux.ibm.com> (raw)
QEMU can now print the ibm,os-term message[1], so let's include it in
the RTAS call. E.g.:
qemu-system-ppc64: OS terminated: Switch to secure mode failed.
