From efe2add7cb7f870ebd90ac4f9637161a4821200a Mon Sep 17 00:00:00 2001 From: Cédric Le Goater Date: Tue, 5 Jun 2018 08:56:26 +0200 Subject: spapr/vio: deprecate the "irq" property VIO devices have an "irq" property that can be used by the sPAPR IRQ allocator as an IRQ number hint. But it is not set in QEMU nor in libvirt. It brings unnecessary complexity to the underlying layers managing the IRQ number space and it is in full opposition with the new static IRQ allocator we want to introduce in sPAPR. Let's deprecate it to simplify the spapr_irq_alloc routine in the future.
