Use smbios-entry-point-type='auto' for newer machine types as a workaround for Windows not detecting SMBIOS tables. Which makes QEMU pick SMBIOS tables based on configuration (with 2.x preferred and fallback to 3.x if the former isn't compatible with configuration)
Default compat setting of smbios-entry-point-type after series for pc/q35 machines: * 9.0-newer: 'auto' * 8.1-8.2: '64' * 8.0-older: '32' Resolves: https://gitlab.com/qemu-project/qemu/-/issues/2008 Signed-off-by: Igor Mammedov <imamm...@redhat.com> Reviewed-by: Ani Sinha <anisi...@redhat.com> Tested-by: Fiona Ebner <f.eb...@proxmox.com> --- hw/i386/pc.c | 2 +- hw/i386/pc_piix.c | 4 ++++ hw/i386/pc_q35.c | 3 +++ 3 files changed, 8 insertions(+), 1 deletion(-) diff --git a/hw/i386/pc.c b/hw/i386/pc.c index 44eb073abd..e80f02bef4 100644 --- a/hw/i386/pc.c +++ b/hw/i386/pc.c @@ -1832,7 +1832,7 @@ static void pc_machine_class_init(ObjectClass *oc, void *data) mc->nvdimm_supported = true; mc->smp_props.dies_supported = true; mc->default_ram_id = "pc.ram"; - pcmc->default_smbios_ep_type = SMBIOS_ENTRY_POINT_TYPE_64; + pcmc->default_smbios_ep_type = SMBIOS_ENTRY_POINT_TYPE_AUTO; object_class_property_add(oc, PC_MACHINE_MAX_RAM_BELOW_4G, "size", pc_machine_get_max_ram_below_4g, pc_machine_set_max_ram_below_4g, diff --git a/hw/i386/pc_piix.c b/hw/i386/pc_piix.c index c9a6c0aa68..18ba076609 100644 --- a/hw/i386/pc_piix.c +++ b/hw/i386/pc_piix.c @@ -525,12 +525,16 @@ DEFINE_I440FX_MACHINE(v9_0, "pc-i440fx-9.0", NULL, static void pc_i440fx_8_2_machine_options(MachineClass *m) { + PCMachineClass *pcmc = PC_MACHINE_CLASS(m); + pc_i440fx_9_0_machine_options(m); m->alias = NULL; m->is_default = false; compat_props_add(m->compat_props, hw_compat_8_2, hw_compat_8_2_len); compat_props_add(m->compat_props, pc_compat_8_2, pc_compat_8_2_len); + /* For pc-i44fx-8.2 and 8.1, use SMBIOS 3.X by default */ + pcmc->default_smbios_ep_type = SMBIOS_ENTRY_POINT_TYPE_64; } DEFINE_I440FX_MACHINE(v8_2, "pc-i440fx-8.2", NULL, diff --git a/hw/i386/pc_q35.c b/hw/i386/pc_q35.c index 8a427c4647..b5922b44af 100644 --- a/hw/i386/pc_q35.c +++ b/hw/i386/pc_q35.c @@ -376,11 +376,14 @@ DEFINE_Q35_MACHINE(v9_0, "pc-q35-9.0", NULL, static void pc_q35_8_2_machine_options(MachineClass *m) { + PCMachineClass *pcmc = PC_MACHINE_CLASS(m); pc_q35_9_0_machine_options(m); m->alias = NULL; m->max_cpus = 1024; compat_props_add(m->compat_props, hw_compat_8_2, hw_compat_8_2_len); compat_props_add(m->compat_props, pc_compat_8_2, pc_compat_8_2_len); + /* For pc-q35-8.2 and 8.1, use SMBIOS 3.X by default */ + pcmc->default_smbios_ep_type = SMBIOS_ENTRY_POINT_TYPE_64; } DEFINE_Q35_MACHINE(v8_2, "pc-q35-8.2", NULL, -- 2.39.3
