From d9c34f9c6c745f6a8123a872b33990ab564c614a Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Wed, 3 May 2017 14:56:58 +0200 Subject: [PATCH] hw/arm/virt: explicitly allocate cpu_index for cpus Currently cpu_index is implicitly auto assigned during cpu.realize() time cpu_exec_realizefn()->cpu_list_add(). It happens to match index in possible_cpus so take control over it and make board initialize cpu_index to possible_cpus index explicitly. It will at least document that board is in control of it and when '-device cpu' support comes it will keep cpu_index stable regardless of order cpus are created so it won't break migration. Within this series it will be used for internal conversion from storing cpu_index based NUMA node bitmaps to property based mapping with possible_cpus, And will allow map cpu_index to a CPU entry in possible_cpus array.
