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-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'
|

|
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)
