kunit: Fix TabError, remove defconfig code and handle when there is no kunitconfig

2020-06-01T20:14:07+00:00

The identation before this code
(`if not os.path.exists(cli_args.build_dir):``)
was with spaces instead of tabs after fixed up merge conflits,
this commit revert spaces to tabs:

[iha@bbking linux]$ tools/testing/kunit/kunit.py run
  File "tools/testing/kunit/kunit.py", line 247
    if not linux:
                ^

    request.defconfig,

Handles when there is no .kunitconfig, the error due to merge conflicts
between the following:

kunit: use KUnit defconfig by default

2020-05-22T22:23:28+00:00

To improve the usability of KUnit, defconfig is used
by default if no kunitconfig is present.

To make KUnit easier to use, and to avoid overwriting object and
.config files, the default KUnit build directory is set to .kunit

kunit: kunit_tool: Separate out config/build/exec/parse

2020-05-11T22:53:40+00:00

Add new subcommands to kunit.py to allow stages of the existing 'run'
subcommand to be run independently:
- 'config': Verifies that .config is a subset of .kunitconfig
- 'build': Compiles a UML kernel for KUnit
- 'exec': Runs the kernel, and outputs the test results.
- 'parse': Parses test results from a file or stdin

The 'run' command continues to behave as before.

Merge tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx

2020-04-03T20:12:26+00:00

Pull SPDX updates from Greg KH:
 "Here are three SPDX patches for 5.7-rc1.

  One fixes up the SPDX tag for a single driver, while the other two go
  through the tree and add SPDX tags for all of the .gitignore files as
  needed.

  Nothing too complex, but you will get a merge conflict with your
  current tree, that should be trivial to handle (one file modified by
  two things, one file deleted.)

  All three of these have been in linux-next for a while, with no
  reported issues other than the merge conflict"

test_prefix_poundsign and test_output_with_prefix_isolated_correctly

kunit: subtests should be indented 4 spaces according to TAP

2020-03-26T20:08:41+00:00

Introduce KUNIT_SUBTEST_INDENT macro which corresponds to 4-space
indentation and KUNIT_SUBSUBTEST_INDENT macro which corresponds to
8-space indentation in line with TAP spec (e.g. see "Subtests"
section of https://node-tap.org/tap-protocol/).

Use these macros in place of one or two tabs in strings to clarify
why we are indenting.

kunit: kunit_tool: Allow .kunitconfig to disable config items

2020-03-25T18:13:16+00:00

Rework kunit_tool in order to allow .kunitconfig files to better enforce
that disabled items in .kunitconfig are disabled in the generated
.config.

Previously, kunit_tool simply enforced that any line present in
.kunitconfig was also present in .config, but this could cause problems
if a config option was disabled in .kunitconfig, but not listed in .config
due to (for example) having disabled dependencies.

To fix this, re-work the parser to track config names and values, and
require values to match unless they are explicitly disabled with the
"CONFIG_x is not set" comment (or by setting its value to 'n'). Those
"disabled" values will pass validation if omitted from the .config, but
not if they have a different value.

kunit: add --make_options

2020-03-23T23:08:22+00:00

The kunit.py utility builds an ARCH=um kernel and then runs it.  Add
optional --make_options flag to kunit.py allowing for the operator to
specify extra build options.

This allows use of the clang compiler for kunit:
  tools/testing/kunit/kunit.py run --defconfig \
    --make_options CC=clang --make_options HOSTCC=clang
