Subject: [PATCH 20/20] pc/q35: set SMBIOS entry point type to 'auto' by
default
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: [18/18] c7fc6ac7350bca3ff99e58620710a86218385781
JIRA: https://issues.redhat.com/browse/RHEL-21705
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

due to RHEL machine types
REHL only parts:
Fix RHEL 'pc' machine types at SMBIOS 2.X
for the latest RHEL 'q35' machine type use version autoselect
which propagates to RHEL 9.4 q35 macine type while RHEL 9.2 q35 and older
are kept at SMBIOS_ENTRY_POINT_TYPE_32 (see: pc_q35_machine_rhel920_options)
