It is possible that certain config levels are not available, even
if the max level includes the level. There can be missing levels in
some platforms. So ignore the level when called for information dump
for all levels and fail if specifically ask for the missing level.
Here the changes is to continue reading information about other levels
even if we fail to get information for the current level. But use the
"processed" flag to indicate the failure. When the "processed" flag is
not set, don't dump information about that level.

Speed Select
There are some platforms, where there limited support of Intel(R) SST
features. Here perf-profile has only one base configuration and limited
support of commands. But still has support for discovery of base-freq and
turbo-freq features. So it is important to show minimum features to use
base-freq and turbo-freq features.
Here the change are:
- When there is no support of CONFIG_TDP_GET_LEVELS_INFO, then instead
of treating this as fatal error, treat this with number of config levels
= 0, that means only base level 0 is present.
- There is no support of mail box commands to get base frequencies or
turbo frequencies. Here present base frequency by reading cpufreq
base freq and turbo frequency by reading MSR 0x1AD.
- Don't display any field, which has value == 0.

There is an expectation in the CLX platform for SST base-freq feature that
Scaling min frequency be different for high and low priority cores.
This is the way the firmware will understand the priority.
So this change will look at high priority and low priority cores, and set
scaling_min_freq to P1High for high priority cores and P1Low to low
priority cores.

In CLX_N base_frequency is read from cpufreq sysfs, where units are in

the enable and disable operations. This can be improved by adding an int

getting used
The turbo-freq feature is dependent on the core-power feature. If the
core-power feature is disabled while the turbo-freq feature is enabled,
this will break the turbo-freq feature. This is a firmware limitation,
where they can't return error under this scenario.
So when trying to disable core-power, make sure that the turbo-freq
feature is not enabled. If it enabled, return error if user is trying to
disable the core-power feature.

Introduce --auto|-a option to turbo-freq enable feature, so that it
does in one step for users who are OK by setting all passed target cores
as high priority and set in CLOS 0 and remaining in CLOS 3. In this way,
users don't have to take multiple steps to enable turbo-freq feature. For
users who want more fine grain control, they can always use core-power
feature to set custom CLOS configuration and assignment.
While here also print the error to output when clos configuration fails.
For example
intel-speed-select -c 0-4 turbo-freq enable --auto
The above command will enable turbo-freq and core-power feature. Also
mark CPU 0 to CPU 4 as high priority.

inconsistency the error in the SW GSO case does not get back to the

Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per

possibly hanging forever. However, scripts and other binaries can still
hang forever. This adds a global timeout to each test script run.
To make this configurable (e.g. as needed in the "rtc" test case),
include a new per-test-directory "settings" file (similar to "config")
that can contain kselftest-specific settings. The first recognized field
is "timeout".
Additionally, this splits the reporting for timeouts into a specific
"TIMEOUT" not-ok (and adds exit code reporting in the remaining case).

Return errno when open_memstream() fails and add two new speciall error
codes for when an invalid, non BPF file or one without BTF is passed to
symbol__disassemble_bpf(), so that its callers can rely on
symbol__strerror_disassemble() to convert that to a human readable error
message that can help figure out what is wrong, with hints even.

We should return errno or the annotation extra range understood by
symbol__strerror_disassemble() instead of -1, fix it, returning ENOMEM
instead.

They are called from symbol__annotate() and to propagate errors that can
help understand the problem make them return what
symbol__strerror_disassemble() known, i.e. errno codes and other
annotation specific errors in a special, out of errnos, range.

We were just returning -1 in symbol__annotate() when symbol__annotate()
failed, propagate its error as it is used later to pass to
symbol__strerror_disassemble() to present a error message to the user,
that in some cases were getting:
"Invalid -1 error code"
Fix it to propagate the error.

Callers of symbol__annotate() expect a errno value or some other
extended error value range in symbol__strerror_disassemble() to
convert to a proper error string, fix it when propagating a failure to
find the arch specific annotation routines via arch__find(arch_name).

The callers of symbol__annotate2() use symbol__strerror_disassemble() to
convert its failure returns into a human readable string, so
propagate error values from functions it calls, starting with
perf_env__arch() that when fails the right thing to do is to look at
'errno' to see why its possible call to uname() failed.

I.e. if evsel->evlist or evsel->evlist->env isn't set, return the
environment for the running machine, as that would be set if reading

The Intel fixed counters use a special table to override the JSON
information.
During this override the period information from the JSON file got
dropped, which results in inst_retired.any and similar running with
frequency mode instead of a period.
Just specify the expected period in the table.

When the LBR data and the instructions in a binary do not match the loop
printing instructions could get confused and print a long stream of
bogus <bad> instructions.
The problem was that if the instruction decoder cannot decode an
instruction it ilen wasn't initialized, so the loop going through the
basic block would continue with the previous value.
Harden the code to avoid such problems:
- Make sure ilen is always freshly initialized and is 0 for bad
instructions.
- Do not overrun the code buffer while printing instructions
- Print a warning message if the final jump is not on an instruction
boundary.

Specification claims latest version of jitdump file format is 2. Current
jit dump reading code treats 1 as the latest version.
Correct spec to match code.
The original language made it unclear the value to be written in the
magic field.
Revise language that the writer always writes the same value. Specify
that the reader uses the value to detect endian mismatches.

During perf inject --jit, JIT_CODE_MOVE records were injecting MMAP records
with an incorrect filename. Specifically it was missing the ".so" suffix.
Further the JIT_CODE_LOAD record were silently truncating the
jr->load.code_index field to 32 bits before generating the filename.
Make both records emit the same filename based on the full 64 bit
code_index field.
Fixes: 9b07e27f88b9 ("perf inject: Add jitdump mmap injection support")
