Allow finer control of reporting dynamic subtests instead of
unconditionally assuming that the main subtest result and logs are
uninteresting if the subtest has dynamic subtests.
The default is still to remove subtest results when the subtest has
dynamic subtests. Other options are:
keep-subtests: Remove the dynamic subtests instead, for cases when a
stable test count is more important.
keep-all: Remove nothing.
keep-requested: Remove the results that were not directly requested to
be executed. This option is useful in cases where the test selection
is a hand-picked mix of subtests and particular dynamic subtests.

The gcc compiler has a feature that enables checking the code coverage
in runtime[1].
[1] See https://www.kernel.org/doc/html/latest/dev-tools/gcov.html
The Linux Kernel comes with an option to enable such feature:
./scripts/config -e DEBUG_FS -e GCOV_KERNEL
The driver's Makefile also needs change to enable it. For instance, in
order to enable GCOV for all DRM drivers, one would need to run:
for i in $(find drivers/gpu/drm/ -name Makefile); do
sed '1 a GCOV_PROFILE := y' -i $i
done
This patch adds support for it by:
a) Implementing a logic to cleanup the code coverage counters via sysfs;
b) Calling a script responsible for collecging code coverage data.
The implementation works with two modes:
1) It zeroes the counters, run all IGT tests and collects the code
coverage results at the end.
This implies that no tests would crash the driver, as otherwise the
results won't be collected;
This is faster, as collecting code coverage data can take several
seconds.
2) For each test, it will clean the code coverage counters, run the and
collect the results.
This is more reliable, as a Kernel crash/OOPS won't affect the
results of the previously ran tests.

Without root permissions, most IGT tests won't actually run, but they
would be displayed at the runner's output as if everything went fine.
In order to avoid that, check if one attempts to run IGT without root
permission. Such check can be disbled with a new command line option:
--allow-non-root
As runner_tests runs as non-root, most unit tests need to pass
--allow-non-root in order for them to not return an error.

Disk usage limit is a limit of disk space taken, per (dynamic)
subtest. If the test's output, kernel log included, exceeds this
limit, the test is killed, similarly to killing the test when the
kernel gets tainted.

A new config option, --per-test-timeout, sets a time a single test
cannot exceed without getting itself killed. The time resets when
starting a subtest or a dynamic subtest, so an execution with
--per-test-timeout=20 can indeed go over 20 seconds a long as it
launches a dynamic subtest within that time.
As a bonus, verbose log level from runner now also prints dynamic
subtest begin/result.

If the network goes down while testing, CI tends to interpret that as
the device being down, cutting its power after a while. This causes an
incomplete to an innocent test, increasing noise in the results.
A new flag to --abort-on-monitored-error, "ping", uses liboping to
ping a host configured in .igtrc with one ping after each test
execution and aborts the run if there is no reply in a hardcoded
amount of time.
v2:
- Use a higher timeout
- Allow hostname configuration from environment
v3:
- Use runner_c_args for holding c args for runner
- Handle runner's meson options in runner/meson.build
- Instead of one ping with 20 second timeout, ping with 1 second timeout
for a duration of 20 seconds
v4:
- Rebase
- Use now-exported igt_load_igtrc instead of copypaste code
- Use define for timeout, clearer var name for single attempt timeout

Currently, runner already collects all subtest names into job_list.
--list-all allows to output it to stdout.
--blacklist option takes a filename as an argument and adds all regexes
from that file to the exclusion list.
v2:
- Update exclude/include regex matches for tests without
subtests to be matched with pigtit-like name (Petri)
- Replace relative paths with those formatted with testdatadir (Petri)
- Minor codestyle changes
v3:
- Print test names in lowercase (Petri)
v4:
- Replaced custom str_to_lower with generate_piglit_name (Petri)
- Minor codestyle changes

POSIX ERE, while pretty standard is also very old and severely limited.
In fact, it's so limited that Intel CI's own test blacklist,
tests/intel-ci/blacklist.txt, doesn't even work with it due to the lack
of support for backreferences.
Since we're already using glib in other parts of igt, let's just start
using glib's regular expression matching instead of the POSIX regex API.
This gives us full perl compatible regular expressions and in turn, also
gives us python compatible regular expressions to match piglit.

This allows us to test the parsing using fmemopen(), limiting the amount

Deviating a bit from the piglit command line flag, igt_runner takes an
optional comma-separated list as an argument to
--abort-on-monitored-error for the list of conditions to abort
on. Without a list all possible conditions will be checked.
Two conditions implemented:
- "taint" checks the kernel taint level for TAINT_PAGE, TAINT_DIE and
TAINT_OOPS
- "lockdep" checks the kernel lockdep status
Checking is done after every test binary execution, and if an abort
condition is met, the reason is printed to stderr (unless log level is
quiet) and the runner doesn't execute any further tests. Aborting
between subtests (when running in --multiple-mode) is not done.
v2:
- Remember to fclose
- Taints are unsigned long (Chris)
- Use getline instead of fgets (Chris)
v3:
- Fix brainfart with lockdep
v4:
- Rebase
- Refactor the abort condition checking to pass down strings
- Present the abort result in results.json as a pseudo test result
- Unit tests for the pseudo result
v5:
- Refactors (Chris)
- Don't claim lockdep was triggered if debug_locks is not on
anymore. Just say it's not active.
- Dump lockdep_stats when aborting due to lockdep (Chris)
- Use igt@runner@aborted instead for the pseudo result (Martin)
v6:
- If aborting after a test, generate results.json. Like was already
done for aborting at startup.
- Print the test that would be executed next as well when aborting,
as requested by Tomi.
v7:
- Remove the resolved TODO item from commit message

With --overall-timeout $foo, the runner will stop executing new tests
when $foo seconds have already been used.
A resumed run will start over with no time used, using the same
timeout. This allows for executing a long list of tests piecemeal, in
about $foo length executions.

This is a new test runner to replace piglit. Piglit has been very
useful as a test runner, but certain improvements have been very
difficult if possible at all in a generic test running framework.
Important improvements over piglit:
- Faster to launch. Being able to make assumptions about what we're
executing makes it possible to save significant amounts of time. For
example, a testlist file's line "igt@somebinary@somesubtest" already
has all the information we need to construct the correct command
line to execute that particular subtest, instead of listing all
subtests of all test binaries and mapping them to command
lines. Same goes for the regexp filters command line flags -t and
-x; If we use -x somebinaryname, we don't need to list subtests from
somebinaryname, we already know none of them will get executed.
- Logs of incomplete tests. Piglit collects test output to memory and
dumps them to a file when the test is complete. The new runner
writes all output to disk immediately.
- Ability to execute multiple subtests in one binary execution. This
was possible with piglit, but its semantics made it very hard to
implement in practice. For example, having a testlist file not only
selected a subset of tests to run, but also mandated that they be
executed in the same order.
- Flexible timeout support. Instead of mandating a time tests cannot
exceed, the new runner has a timeout on inactivity. Activity is
any output on the test's stdout or stderr, or kernel activity via
/dev/kmsg.
The runner is fairly piglit compatible. The command line is very
similar, with a few additions. IGT_TEST_ROOT environment flag is still
supported, but can also be set via command line (in place of igt.py in
piglit command line).
The results are a set of log files, processed into a piglit-compatible
results.json file (BZ2 compression TODO). There are some new fields in
the json for extra information:
- "igt-version" contains the IGT version line. In
multiple-subtests-mode the version information is only printed once,
so it needs to be duplicated to all subtest results this way.
- "dmesg-warnings" contains the dmesg lines that triggered a
dmesg-warn/dmesg-fail state.
- Runtime information will be different. Piglit takes a timestamp at
the beginning and at the end of execution for runtime. The new
runner uses the subtest output text. The binary execution time will
also be included; The key "igt@somebinary" will have the runtime of
the binary "somebinary", whereas "igt@somebinary@a" etc will have
the runtime of the subtests. Substracting the subtest runtimes from
the binary runtime yields the total time spent doing setup in
igt_fixture blocks.
v2:
- use clock handling from igt_core instead of copypaste
- install results binary
- less magic numbers
- scanf doesn't give empty strings after all
- use designated array initialization with _F_JOURNAL and pals
- add more comments to dump_dmesg
- use signal in kill_child instead of bool
- use more 'usual' return values for execute_entry
- use signal number instead of magic integers
- use IGT_EXIT_INVALID instead of magic 79
- properly remove files in clear_test_result_directory()
- remove magic numbers
- warn if results directory contains extra files
- fix naming in matches_any
- construct command line in a cleaner way in add_subtests()
- clarify error in filtered_job_list
- replace single string fprintfs with fputs
- use getline() more sanely
- refactor string constants to a shared header
- explain non-nul-terminated string handling in resultgen
- saner line parsing
- rename gen_igt_name to generate_piglit_name
- clean up parse_result_string
- explain what we're parsing in resultgen
- explain the runtime accumulation in add_runtime
- refactor result overriding
- stop passing needle sizes to find_line functions
- refactor stdout/stderr parsing
- fix regex whitelist compiling

- log_level parsing with typeof
- pass stdout/stderr to usage() instead of a bool
- fix absolute_path overflow
- refactor settings serialization
- remove maybe_strdup function
- refactor job list serialization
- refactor resuming, add new resume binary
- catch mmap failure correctly
v3:
- rename runner to igt_runner, etc
- add meson option for building the runner
- use UPPER_CASE names for string constants
- add TODO comments for future refactoring
- add a midding close()
- const correctness where applicable
- also build with autotools
