From 74e51a38f74537d7260f0d45fb01e675f1558163 Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Mon, 6 Jan 2020 15:56:42 +0100 Subject: spapr/xive: Deduce the SpaprXive pointer from XiveTCTX::xptr MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit And use it instead of reaching out to the machine. This allows to get rid of a call to qdev_get_machine() and to reduce the scope of another one so that it is only used within the argument list of error_append_hint(). This is an acceptable tradeoff compared to all it would require to know about the maximum number of CPUs here without calling qdev_get_machine().
