[Qemu-devel] [PATCH 0/7] NUMA code cleanup

[Qemu-devel] [PATCH 0/7] NUMA code cleanup

[Eduardo Habkost]

This cleans up some of the NUMA code: moves declarations to numa.h, rename some
functions, and remove some existing code that was inside main().

Eduardo Habkost (7):
  numa: Move NUMA declarations from sysemu.h to numa.h
  vl.c: Remove unnecessary zero-initialization of NUMA globals
  numa: Move NUMA globals to numa.c
  numa: Make max_numa_nodeid static
  numa: Move QemuOpts parsing to set_numa_nodes()
  numa: Rename option parsing functions
  numa: Rename set_numa_modes() to numa_post_machine_init()

[Qemu-devel] [PATCH 1/7] numa: Move NUMA declarations from sysemu.h to numa.h

[Eduardo Habkost]

Not all sysemu.h users need the NUMA declarations, and keeping them in a
separate file makes easier to see what are the interfaces provided by
numa.c.

[Qemu-devel] [PATCH 2/7] vl.c: Remove unnecessary zero-initialization of NUMA globals

[Eduardo Habkost]

There's no need to zero-initialize globals, they are automatically
initialized to zero.

[Qemu-devel] [PATCH 6/7] numa: Rename option parsing functions

[Eduardo Habkost]

Renaming set_numa_nodes() and numa_init_func() to parse_numa_opts() and
parse_numa() makes the purpose of those functions clearer.

[Qemu-devel] [PATCH 7/7] numa: Rename set_numa_modes() to numa_post_machine_init()

[Eduardo Habkost]

This function does some initialization that needs to be done after
machine init. The function may be eventually removed if we move the
CPUState.numa_node initialization to the CPU init code, but while the
function exists, lets give it a name that makes sense.

Thanks!

Do you think this should go through Michael's tree, like past NUMA
patches, or through yours?

kvm tree does not seem appropriate.
