[PATCH v2 1/1] kunit: Replace kernel.h with the necessary inclusions

by Andy Shevchenko

When kernel.h is used in the headers it adds a lot into dependency hell, especially when there are circular dependencies are involved. Replace kernel.h inclusion with the list of what is really being used.

[PATCH v2] selftests/kselftest/runner.sh: Pass optional command parameters in environment

by Cristian Marussi

Some testcases allow for optional commandline parameters but as of now there is now way to provide such arguments to the runner script. Add support to retrieve such optional command parameters fron environment variables named so as to include the all-uppercase test executable name, sanitized substituting any non-acceptable varname characters with "_", following the pattern: KSELFTEST_<UPPERCASE_SANITIZED_TEST_NAME>_ARGS="options" Optional command parameters support is not available if 'tr' is not installed on the test system.

[PATCH] selftests/powerpc/spectre_v2: Return skip code when miss_percent is high

by Thadeu Lima de Souza Cascardo

A mis-match between reported and actual mitigation is not restricted to the Vulnerable case. The guest might also report the mitigation as "Software count cache flush" and the host will still mitigate with branch cache disabled. So, instead of skipping depending on the detected mitigation, simply skip whenever the detected miss_percent is the expected one for a fully mitigated system, that is, above 95%.

[PATCH v2] kunit: tool: Default --jobs to number of CPUs

by David Gow

The --jobs parameter for kunit_tool currently defaults to 8 CPUs, regardless of the number available. For systems with significantly more (or less), this is not as efficient. Instead, default --jobs to the number of CPUs available to the process: while there are as many superstitions as to exactly what the ideal jobs:CPU ratio is, this seems sufficiently sensible to me. A new helper function to get the default number of jobs is added: get_default_jobs() -- this is used in kunit_tool_test instead of a hardcoded value, or an explicit call to len(os.sched_getaffinity()), so should be more flexible if this needs to change in the future.

[PATCH v2 1/2] kunit: tool: use dataclass instead of collections.namedtuple

by Daniel Latypov

namedtuple is a terse way of defining a collection of fields. However, it does not allow us to annotate the type of these fields. It also doesn't let us have any sort of inheritance between types. Since commit df4b0807ca1a ("kunit: tool: Assert the version requirement"), kunit.py has asserted that it's running on python >=3.7. So in that case use a 3.7 feature, dataclasses, to replace these. Changes in detail: * Make KunitExecRequest contain all the fields needed for exec_tests * Use inheritance to dedupe fields * also allows us to e.g. pass a KUnitRequest in as a KUnitParseRequest * this has changed around the order of some fields * Use named arguments when constructing all request objects in kunit.py * This is to prevent accidentally mixing up fields, etc. Signed-off-by: Daniel Latypov <dlatypov(a)google.com> Reviewed-by: Brendan Higgins <brendanhiggins(a)google.com> --- v1 -> v2: no change, clean rebase onto linux-kselftest kunit branch. --- tools/testing/kunit/kunit.py | 139 +++++++++++++------------ tools/testing/kunit/kunit_tool_test.py | 6 +- 2 files changed, 75 insertions(+), 70 deletions(-) diff --git a/tools/testing/kunit/kunit.py b/tools/testing/kunit/kunit.py index 8c52faf5787c..4f5c7984cf3f 100755 --- a/tools/testing/kunit/kunit.py +++ b/tools/testing/kunit/kunit.py @@ -15,38 +15,57 @@ import time assert sys.version_info >= (3, 7), "Python version is too old" -from collections import namedtuple +from dataclasses import dataclass from enum import Enum, auto -from typing import Iterable, Sequence, List +from typing import Any, Iterable, Sequence, List, Optional import kunit_json import kunit_kernel import kunit_parser -KunitResult = namedtuple('KunitResult', ['status','result','elapsed_time']) -

[PATCH v2] kunit: tool: make `build` subcommand also reconfigure if needed

by Daniel Latypov

If I created a kunitconfig file that was incomplete, then $ ./tools/testing/kunit/kunit.py build --kunitconfig=my_kunitconfig would silently drop all the options with unmet dependencies! This is because it doesn't do the config check that `kunit.py config` does. So if I want to safely build a kernel for testing, I have to do $ ./tools/testing/kunit/kunit.py config <flags> $ ./tools/testing/kunit/kunit.py build <flags, again> It seems unlikely that any user of kunit.py would want the current `build` semantics. So make it effectively do `kunit.py config` + `kunit.py build`.

[PATCH] kunit: tool: fix newly introduced typechecker errors

by Daniel Latypov

After upgrading mypy and pytype from pip, we see 2 new errors when running ./tools/testing/kunit/run_checks.py. Error #1: mypy and pytype They now deduce that importlib.util.spec_from_file_location() can return None and note that we're not checking for this. We validate that the arch is valid (i.e. the file exists) beforehand. Add in an `asssert spec is not None` to appease the checkers. Error #2: pytype bug https://github.com/google/pytype/issues/1057 It doesn't like `from datetime import datetime`, specifically that a type shares a name with a module. We can workaround this by either * renaming the import or just using `import datetime` * passing the new `--fix-module-collisions` flag to pytype. We pick the first option for now because * the flag is quite new, only in the 2021.11.29 release. * I'd prefer if people can just run `pytype <file>` Signed-off-by: Daniel Latypov <dlatypov(a)google.com> --- tools/testing/kunit/kunit_kernel.py | 1 + tools/testing/kunit/kunit_parser.py | 4 ++-- 2 files changed, 3 insertions(+), 2 deletions(-) diff --git a/tools/testing/kunit/kunit_kernel.py b/tools/testing/kunit/kunit_kernel.py index 12085e04a80c..44bbe54f25f1 100644 --- a/tools/testing/kunit/kunit_kernel.py +++ b/tools/testing/kunit/kunit_kernel.py @@ -209,6 +209,7 @@ def get_source_tree_ops_from_qemu_config(config_path: str, # exists as a file. module_path = '.' + os.path.join(os.path.basename(QEMU_CONFIGS_DIR), os.path.basename(config_path)) spec = importlib.util.spec_from_file_location(module_path, config_path) + assert spec is not None config = importlib.util.module_from_spec(spec) # See https://github.com/python/typeshed/pull/2626 for context. assert isinstance(spec.loader, importlib.abc.Loader) diff --git a/tools/testing/kunit/kunit_parser.py b/tools/testing/kunit/kunit_parser.py index 8e42b6ef3fe3..0850cb4bce89 100644 --- a/tools/testing/kunit/kunit_parser.py +++ b/tools/testing/kunit/kunit_parser.py @@ -13,7 +13,7 @@ from __future__ import annotations import re from collections import namedtuple -from datetime import datetime +import datetime from enum import Enum, auto from functools import reduce from typing import Iterable, Iterator, List, Optional, Tuple @@ -520,7 +520,7 @@ ANSI_LEN = len(red('')) def print_with_timestamp(message: str) -> None: """Prints message with timestamp at beginning.""" - print('[%s] %s' % (datetime.now().strftime('%H:%M:%S'), message)) + print('[%s] %s' % (datetime.datetime.now().strftime('%H:%M:%S'), message)) def format_test_divider(message: str, len_message: int) -> str: """ base-commit: 7fa7ffcf9babaea2f0a81681b4ef460ee4b93278 -- 2.34.1.173.g76aa8bc2d0-goog
