From f3b176402fa92149320dcd5479916ccb39cfa0a8 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Thu, 28 Nov 2013 17:27:02 +0100 Subject: isa: Clean up use of cannot_instantiate_with_device_add_yet MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Drop it when there's no obvious reason why device_add could not work. Else keep and document why. * isa-fdc: drop * i8042: drop, even though its I/O base is hardcoded (because you could conceivably still add one to a board that has none), and even though PC board code wires up the A20 line (because that wiring is optional) * port92: keep because it needs additional wiring by port92_init() * mc146818rtc: keep because it needs to be wired up by rtc_init() * m48t59_isa: keep because needs to be wired up by m48t59_init_isa() * isa-pit, kvm-pit: keep (in their abstract base pic-common) because the PIT needs additional wiring by board code, depending on HPET presence * pcspk: keep because of pointer property pit, and because realize sets global pcspk_state * vmmouse: keep because of pointer property ps2_mouse * vmport: keep because realize sets global port_state * isa-i8259, kvm-i8259: keep (in their abstract base pic-common), because the PICs' IRQ input lines are set up by board code, and the wiring of the slave to the master is hard-coded in device model code Signed-off-by: Markus Armbruster Signed-off-by: Andreas Färber --- hw/audio/pcspk.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'hw/audio') diff --git a/hw/audio/pcspk.c b/hw/audio/pcspk.c index 8e3e178f38..f980d66b2f 100644 --- a/hw/audio/pcspk.c +++ b/hw/audio/pcspk.c @@ -192,8 +192,9 @@ static void pcspk_class_initfn(ObjectClass *klass, void *data) dc->realize = pcspk_realizefn; set_bit(DEVICE_CATEGORY_SOUND, dc->categories); - dc->cannot_instantiate_with_device_add_yet = true; /* FIXME explain why */ dc->props = pcspk_properties; + /* Reason: pointer property "pit", realize sets global pcspk_state */ + dc->cannot_instantiate_with_device_add_yet = true; } static const TypeInfo pcspk_info = { -- cgit v1.2.3
