Subject: [PATCH 03/20] hw/i386/pc: Defer smbios_set_defaults() to machine_done
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
RH-Author: Igor Mammedov <imammedo@redhat.com>
RH-MergeRequest: 230: Workaround Windows failing to find 64bit SMBIOS entry point with SeaBIOS
RH-Jira: RHEL-21705
RH-Acked-by: MST <mst@redhat.com>
RH-Acked-by: Ani Sinha <None>
RH-Commit: [1/18] 9d4c1d1a910fec7d310429d6fc0b10c798932db7
JIRA: https://issues.redhat.com/browse/RHEL-21705
commit: a0204a5ed091dfe79aced7ec8f3ce1931fd25816
Author: Bernhard Beschow <shentey@gmail.com>
Handling most of smbios data generation in the machine_done notifier is similar
to how the ARM virt machine handles it which also calls smbios_set_defaults()
there. The result is that all pc machines are freed from explicitly worrying
about smbios setup.

Conflicts: hw/i386/pc_q35.c, hw/i386/pc_piix.c
due to missing 4d3457fef9 (w/i386/pc: Merge pc_guest_info_init() into pc_machine_initfn())
and different signature of smbios_set_defaults() downstream
Fixup: hw/i386/fw_cfg.c to account for downstream changes smbios_set_defaults()
