From 4fe75a8ccd8005f8d0322c5b85ebee6243b2e753 Mon Sep 17 00:00:00 2001 From: Cédric Le Goater Date: Mon, 18 Jun 2018 19:34:00 +0200 Subject: spapr: split the IRQ allocation sequence Today, when a device requests for IRQ number in a sPAPR machine, the spapr_irq_alloc() routine first scans the ICSState status array to find an empty slot and then performs the assignement of the selected numbers. Split this sequence in two distinct routines : spapr_irq_find() for lookups and spapr_irq_claim() for claiming the IRQ numbers. This will ease the introduction of a static layout of IRQ numbers.
