From ebd6be089b4c87554362b516c3ba530217d3f3db Mon Sep 17 00:00:00 2001 From: David Gibson Date: Thu, 26 Sep 2019 14:11:23 +1000 Subject: spapr, xics, xive: Move cpu_intc_create from SpaprIrq to SpaprInterruptController MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This method essentially represents code which belongs to the interrupt controller, but needs to be called on all possible intcs, rather than just the currently active one. The "dual" version therefore calls into the xics and xive versions confusingly. Handle this more directly, by making it instead a method on the intc backend, and always calling it on every backend that exists. While we're there, streamline the error reporting a bit.
