And then later QEMU adds default/'-smbios type' entries on top into the same blob. It makes impossible to generate tables more than once, hence 'immutable' guard was used. Make it possible to regenerate final blob by storing user provided blobs into a dedicated area (usr_blobs) and then copy it when composing final blob. Which also makes handling of -smbios options consistent. As side effect of this and previous commits there is no need to generate legacy smbios_entries at the time options are parsed. Instead compose smbios_entries on demand from usr_blobs like it is done for non-legacy SMBIOS tables.

However doing the later makes SMBIOS tables broken since SeaBIOS doesn't expect that. Rather than trying to add support for type4 to legacy code (both QEMU and SeaBIOS), simplify smbios_get_table_legacy() by dropping not relevant check in legacy code and error out on type4 blob. Signed-off-by: Igor Mammedov Reviewed-by: Ani Sinha Tested-by: Fiona Ebner --- * The issue affects 'isapc' and pc-i440fx-2.0. the later is in deprecated state and to be dropped in near future * possibly the same issue applies to other SMBIOS types above type 1 but I haven't tested that, and well tables that aren't generated by SeaBIOS can get be added just fine (tested type11 blob). So I went with a minimal change to fixup type4 only that I'm touching. Leaving the rest for other time or when someone complains about it, which is very unlikely given it's really only remaining isapc machine. I'd very much prefer to deprecate 'isapc' and then drop all legacy related code (it will benefit not only SMBIOS but other code as well). BTW: 'isapc' is in semi-dead, I cna't boot RHEL6 on it with KVM enabled anymore (RHEL9 host), TCG still boots though. One more reason to get deprecate it. --- include/hw/firmware/smbios.h | 2 +- hw/i386/fw_cfg.c | 3 +-- hw/smbios/smbios.c | 18 ++++++++++++++---- 3 files changed, 16 insertions(+), 7 deletions(-) diff --git a/include/hw/firmware/smbios.h b/include/hw/firmware/smbios.h index 7b42e7b4ac..0f0dca8f83 100644 --- a/include/hw/firmware/smbios.h +++ b/include/hw/firmware/smbios.h @@ -313,7 +313,7 @@ void smbios_set_defaults(const char *manufacturer, const char *product, const char *version, bool uuid_encoded, SmbiosEntryPointType ep_type);

And exposing some symbols so that they could be shared between smbbios.c and new smbios_legacy.c plus some meson magic to build smbios_legacy.c only for 'pc' machine and otherwise replace it with stub if not selected.

Use newer error_setg() everywhere, beside consistency it will allow to detect error condition without killing QEMU and attempt switch-over to SMBIOS3.x tables/entrypoint in follow up patch. while at it, clear smbios_tables pointer after freeing. that will avoid double free if smbios_get_tables() is called multiple times.

So instead of it (or rather in addition) this patch will try to workaround the issue. aka, use smbios-entry-point-type=auto to make QEMU try generating conservative SMBIOS 2.0 tables and if that fails (due to limits/requested configuration) fallback to SMBIOS 3.0 tables. With this in place majority of users will use SMBIOS 2.0 tables which work fine with (Windows + legacy BIOS). The configurations that is not to possible to describe with SMBIOS 2.0 will switch automatically to SMBIOS 3.0 (which will trigger Windows bug but there is nothing QEMU can do here, so go and aks Microsoft to real fix).
