Add basic NUMA awareness routines, using a minimal src/port/pg_numa.c portability wrapper and an optional build dependency, enabled by --with-libnuma configure option. For now this is Linux-only, other platforms may be supported later. A built-in SQL function pg_numa_available() allows checking NUMA support, i.e. that the server was built/linked with the NUMA library. The main function introduced is pg_numa_query_pages(), which allows determining the NUMA node for individual memory pages. Internally the function uses move_pages(2) syscall, as it allows batching, and is more efficient than get_mempolicy(2).

# These files are used by the Postgres backend, and also by frontend
|
|
# programs. Primarily, they are meant to provide portability on systems
|
|
# with broken/missing library files.
|
|
#
|
|
# This makefile generates three outputs:
|
|
#
|
|
# libpgport.a - contains object files with FRONTEND defined,
|
|
# for use by client applications
|
|
#
|
|
# libpgport_shlib.a - contains object files with FRONTEND defined,
|
|
# built suitably for use in shared libraries; for use
|
|
# by frontend libraries
|
|
#
|
|
# libpgport_srv.a - contains object files without FRONTEND defined,
|
|
# for use only by the backend
|
|
#
|
|
# LIBOBJS is set by configure (via Makefile.global) to be the list of object
|
|
# files that are conditionally needed as determined by configure's probing.
|
|
# OBJS adds additional object files that are always compiled.
