As the number of test cases and length of execution grows it's useful to select only a subset of tests. In TLS for instance we have a matrix of variants for different crypto protocols and during development mostly care about testing a handful. This is quicker and makes reading output easier. This patch adds argument parsing to kselftest_harness. It supports a couple of ways to filter things, I could not come up with one way which will cover all cases. The first and simplest switch is -r which takes the name of a test to run (can be specified multiple times). For example: $ ./my_test -r some.test.name -r some.other.name will run tests some.test.name and some.other.name (where "some" is the fixture, "test" and "other" and "name is the test.) Then there is a handful of group filtering options. f/v/t for filtering by fixture/variant/test. They have both positive (match -> run) and negative versions (match -> skip). If user specifies any positive option we assume the default is not to run the tests. If only negative options are set we assume the tests are supposed to be run by default. Usage: ./tools/testing/selftests/net/tls [-h|-l] [-t|-T|-v|-V|-f|-F|-r name] -h print help -l list all tests -t name include test -T name exclude test -v name include variant -V name exclude variant -f name include fixture -F name exclude fixture -r name run specified test Test filter options can be specified multiple times. The filtering stops at the first match. For example to include all tests from variant 'bla' but not test 'foo' specify '-T foo -v bla'. Here we can request for example all tests from fixture "foo" to run: ./my_test -f foo or to skip variants var1 and var2: ./my_test -V var1 -V var2 Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
