Rather than having to explicitly list each and every driver to disable in a build, we can use a small python script and the python glob library to expand out the wildcards. This means that we can configure meson using e.g.
meson -Ddisable_drivers=crypto/*,event/* build to do a build omitting all the crypto and event drivers. Explicitly specified drivers e.g. net/i40e, work as before, and can be mixed with wildcarded drivers as required. Signed-off-by: Bruce Richardson <bruce.richard...@intel.com> --- V3: - added check for correct number of params - replaced list comprehension with loops for simplicity - allow running without meson environmental vars set (for easier testing) V2: - fixed file suffix - since it's being called from meson, make this python3 only - remove use of chdir() - use '\n' rather than ',' between entries --- buildtools/list-dir-globs.py | 21 +++++++++++++++++++++ buildtools/meson.build | 2 +- drivers/meson.build | 3 ++- 3 files changed, 24 insertions(+), 2 deletions(-) create mode 100755 buildtools/list-dir-globs.py diff --git a/buildtools/list-dir-globs.py b/buildtools/list-dir-globs.py new file mode 100755 index 000000000..b9a536869 --- /dev/null +++ b/buildtools/list-dir-globs.py @@ -0,0 +1,21 @@ +#! /usr/bin/env python3 +# SPDX-License-Identifier: BSD-3-Clause +# Copyright(c) 2020 Intel Corporation + +import sys +import os +from glob import iglob +from os.path import join, relpath, isdir + +if len(sys.argv) != 2: + print("Usage: {0} <path-glob>[,<path-glob>[,...]]".format(sys.argv[0])) + sys.exit(1) + +root = '.' +if 'MESON_SOURCE_ROOT' in os.environ and 'MESON_SUBDIR' in os.environ: + root = join(os.environ['MESON_SOURCE_ROOT'], os.environ['MESON_SUBDIR']) + +for path in sys.argv[1].split(','): + for p in iglob(join(root, path)): + if isdir(p): + print(relpath(p)) diff --git a/buildtools/meson.build b/buildtools/meson.build index cd1d05403..0f563d89a 100644 --- a/buildtools/meson.build +++ b/buildtools/meson.build @@ -4,7 +4,7 @@ subdir('pmdinfogen') pmdinfo = find_program('gen-pmdinfo-cfile.sh') - +list_dir_globs = find_program('list-dir-globs.py') check_experimental_syms = find_program('check-experimental-syms.sh') # set up map-to-def script using python, either built-in or external diff --git a/drivers/meson.build b/drivers/meson.build index 29708cc2b..3ee998d80 100644 --- a/drivers/meson.build +++ b/drivers/meson.build @@ -17,7 +17,8 @@ dpdk_driver_classes = ['common', 'event', # depends on common, bus, mempool and net.
