[PATCH 0/3] hw/smbios: Add dedicated handle range for Type 8 tables

Posted by Alexander Gryanko 1 week ago

This is a continuation of the work originally proposed by Felix Wu [1],
which changed the SMBIOS Type 8 handle base unconditionally. As Igor
Mammedov pointed out in review, an unconditional change would break
live migration between hosts running different QEMU versions.
This series addresses the review feedback by:
- Using machine-type versioning (pc-*-11.2) to opt in to the new
  behavior, preserving T0_BASE for older machine types
- Adding a PCMachineClass field to control the setting per machine type
- Adding tests for both new and compat machine versions
