Commit c87759ce876a fixed a regression affecting pc-q35 machines by
introducing a new pc-q35-4.0.1 machine version to be used instead
of pc-q35-4.0. The only purpose was to revert the default behaviour
of not using split irqchip, but the change also introduced the usual
hw_compat and pc_compat bits

These were designed to facilitate testing but should provide enough function to
be useful in other contexts.
Only a subset of the functions of each peripheral is implemented, mainly due to
the lack of a standard way to handle electrical connections (like GPIO pins).

Add struct NumaState in MachineState and move existing numa global
nb_numa_nodes(renamed as "num_nodes") into NumaState. And add variable
numa_support into MachineClass to decide which submachines support NUMA.

Hi,
This series seems to have some coding style problems. See output below for
more information:
Subject: [Qemu-devel] [PATCH 0/3] Collecting TB Execution Frequency
Type: series
Message-id: 20190614135332.127
This series of patches will build Heterogeneous Memory Attribute Table (HMAT)
according to the command line. The ACPI HMAT describes the memory attributes,
such as memory side cache attributes and bandwidth and latency details,
related to the System Physical Address (SPA) Memory Ranges.
