[PATCH v3 0/5] Building PPTT with root node and identical implementation flag
Posted by Alireza Sanaee via 6 months, 3 weeks ago
OS like Linux is using PPTT processor node's identical implementation
flag [1] to infer whether the whole system or a certain CPU cluster is
homogeneous or not [2]. QEMU currently only support building homogeneous
system, set the flag to indicate the fact. Build a root node in PPTT
for indicates the identical implementation which is needed for a
multi-socket system. Update the related PPTT tables as well.

Since we'll update the test PPTT table data, upgrade the revision of PPTT
we build to revision 3 by handy.

[1] ACPI 6.5 Table 5.158: Processor Structure Flags
[2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/acpi/pptt.c?h=v6.11-rc1#n810

History:
    v2->v3: rebase to 10

Yicong Yang (5):
  tests: virt: Allow changes to PPTT test table
  hw/acpi/aml-build: Set identical implementation flag for PPTT
    processor nodes
  hw/acpi/aml-build: Build a root node in the PPTT table
  hw/acpi/aml-build: Update the revision of PPTT table
  tests: virt: Update expected ACPI tables for virt test
