Subject: [PATCH 19/20] smbios: error out when building type 4 table is not
possible
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: [17/18] 86b1c67bfbe9c0c14a190cd1204b6ccd1de1630f
JIRA: https://issues.redhat.com/browse/RHEL-21705
If SMBIOS v2 version is requested but number of cores/threads
are more than it's possible to describe with v2, error out
instead of silently ignoring the fact and filling core/thread
count with bogus values.
This will help caller to decide if it should fallback to
SMBIOSv3 when smbios-entry-point-type='auto'
