Subject: [PATCH 3/3] powerpc/powernv: only call OPAL_RESEND_DUMP if firmware supports it
Date: Wed, 18 Feb 2015 11:03:44 +1100 [thread overview]
Message-ID: <1424217824-30596-4-git-send-email-stewart@linux.vnet.ibm.com> (raw)
In-Reply-To: <1424217824-30596-1-git-send-email-stewart@linux.vnet.ibm.com>
Not all OPAL platforms support resending system dumps, so check
that current firmware supports it first. Otherwise we get firmware
complaining:
"OPAL: Called with bad token 91 !"
