[PATCH v3 0/2] hw/i386/pc: Update max_cpus and default to SMBIOS

Posted by Suravee Suthikulpanit 10 months, 3 weeks ago

In order to support large number of vcpus, a newer 64-bit SMBIOS
entry point type is needed. Therefore, upgrade the default SMBIOS version
for PC machines to SMBIOS 3.0 for newer systems. Then increase the maximum
number of vCPUs for Q35 models to 1024, which is the limit for KVM.

Changes from V2:
(https://lore.kernel.org/qemu-devel/20230531225127.331998-1-suravee.suthikulpanit@amd.com/)
* Add patch 1.

Changes from V1:
(https://lore.kernel.org/all/YnkDGsIi1vFvXmiP@redhat.com/T/)
 * Bump from 512 to KVM_MAX_VCPUS (per Igor's suggestion)

Thank you,
Suravee
