From 4cc017e505df7e5344e4dfe7fc17711117c5f11f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Tue, 22 Oct 2019 00:32:41 +0200 Subject: [PATCH] serial: register vmsd with DeviceClass MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Migration from old to new code works, however the other way fails for devices that use serial_init/serial_mm_init with "base", used as instance_id previously. (with qdev_set_legacy_instance_id, the alias_id is only used in savevm.c:find_se(), and thus can only be used to match against "legacy" instance id values. On new code, instance_id is generated incrementally from 0 with calculate_new_instance_id(), based on "qdev-path/vmsd-name") Signed-off-by: Marc-André Lureau Reviewed-by: xiaoqiang zhao --- hw/char/serial.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/hw/char/serial.c b/hw/char/serial.c index 233a9e2076..e926845843 100644 --- a/hw/char/serial.c +++ b/hw/char/serial.c @@ -990,8 +990,7 @@ SerialState *serial_init(int base, qemu_irq irq, int baudbase, s->baudbase = baudbase; qemu_chr_fe_init(&s->chr, chr, &error_abort); serial_realize_core(s, &error_fatal); - - vmstate_register(NULL, base, &vmstate_serial, s); + qdev_set_legacy_instance_id(dev, base, 2); qdev_init_nofail(dev); memory_region_init_io(&s->io, NULL, &serial_io_ops, s, "serial", 8); @@ -1006,6 +1005,7 @@ static void serial_class_init(ObjectClass *klass, void *data) /* internal device for serialio/serialmm, not user-creatable */ dc->user_creatable = false; + dc->vmsd = &vmstate_serial; } static const TypeInfo serial_info = { @@ -1069,7 +1069,7 @@ SerialState *serial_mm_init(MemoryRegion *address_space, qemu_chr_fe_init(&s->chr, chr, &error_abort); serial_realize_core(s, &error_fatal); - vmstate_register(NULL, base, &vmstate_serial, s); + qdev_set_legacy_instance_id(dev, base, 2); qdev_init_nofail(dev); memory_region_init_io(&s->io, NULL, &serial_mm_ops[end], s, -- GitLab
