a9b2f8e2fa tools/power/x86/intel-speed-select: Auto mode for CLX
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.

91d928147b tools/power/x86/intel-speed-select: Correct CLX-N frequency units
In CLX_N base_frequency is read from cpufreq sysfs, where units are in
KHz. The internal units in the code matches the real ratios which are
in 100MHz scale. So when storing units for CLX-N frequencies, convert
to 100MHz scale.

1aa7177cdc tools/power/x86/intel-speed-select: Implement base-freq commands on CascadeLake-N
Add functionality for base-freq info|enable|disable info on CascadeLake-N.

The enable command always returns success, and the disable command always
returns failed because SST-BF cannot be enabled or disabled from the OS on
CascadeLake-N.

Enable command also have support for --auto|-a option, which sets cpufreq
scaling_min to max, so that the high priority base frequency can be the
required minimum for high priority cores. Disable command with -a/--auto
option reset the setting back to the min frequency.

the enable and disable operations.  This can be improved by adding an int
argument to the command function structure, and interpreting 1 as enable

4e26fabfe1 tools/power/x86/intel-speed-select: Refuse to disable core-power when 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.

a6a82f9bcd tools/power/x86/intel-speed-select: Turbo-freq feature auto mode
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.

Thus, the NULL char has to be taken into account on strncpy.

 These patches improve the Kselftest results. Ability to skip targets
 helps avoid running tests that aren't supported in certain environments.
 As an example, bpf tests from mainline aren't supported on stable kernels
 and have dependency on bleeding edge llvm. Being able to skip bpf on
 systems that can't meet this llvm dependency will be helpful.
 
 Kselftest can be built and installed from the main Makefile. This change

4094871db1 udp: only do GSO if # of segs > 1
Prior to this change an application sending <= 1MSS worth of data and
enabling UDP GSO would fail if the system had SW GSO enabled, but the
same send would succeed if HW GSO offload is enabled. In addition to this
inconsistency the error in the SW GSO case does not get back to the
application if sending out of a real device so the user is unaware of this
failure.

With this change we only perform GSO if the # of segments is > 1 even
if the application has enabled segmentation. I've also updated the
relevant udpgso selftests.

6e06983dde selftests: kvm: Fix libkvm build error
Fix the following build error from "make TARGETS=kvm kselftest":

libkvm.a(assert.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC

This error is seen when build is done from the main Makefile using
kselftest target. In this case KBUILD_CPPFLAGS and CC_OPTION_CFLAGS
are defined.

When build is invoked using:

"make -C tools/testing/selftests/kvm" KBUILD_CPPFLAGS and CC_OPTION_CFLAGS
aren't defined.

There is no need to pass in KBUILD_CPPFLAGS and CC_OPTION_CFLAGS for the
check to determine if --no-pie is necessary, which is the case when these
two aren't defined when "make -C tools/testing/selftests/kvm" runs.

Fix it by simplifying the no-pie-option logic. With this change, both
build variations work.

"make TARGETS=kvm kselftest"
"make -C tools/testing/selftests/kvm"

852c8cbf34 selftests/kselftest/runner.sh: Add 45 second timeout per test
Commit a745f7af3c ("selftests/harness: Add 30 second timeout per
test") solves the problem of kselftest_harness.h-using binary tests
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).

This change addresses requests from developers and testers to add

e98df280bc perf script brstackinsn: Fix recovery from LBR/binary mismatch
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.

b59711e9b0 perf inject jit: Fix JIT_CODE_MOVE filename
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.

ee212d6ea2 perf map: Fix overlapped map handling
Whenever an mmap/mmap2 event occurs, the map tree must be updated to add a new
entry. If a new map overlaps a previous map, the overlapped section of the
previous map is effectively unmapped, but the non-overlapping sections are
still valid.

maps__fixup_overlappings() is responsible for creating any new map entries from
the previously overlapped map. It optionally creates a before and an after map.

When creating the after map the existing code failed to adjust the map.pgoff.
This meant the new after map would incorrectly calculate the file offset
for the ip. This results in incorrect symbol name resolution for any ip in the
after region.

Make maps__fixup_overlappings() correctly populate map.pgoff.

Add an assert that new mapping matches old mapping at the beginning of
the after map.

Committer-testing:

Validated correct parsing of libcoreclr.so symbols from .NET Core 3.0 preview9
(which didn't strip symbols).

Preparation:

  ~/dotnet3.0-preview9/dotnet new webapi -o perfSymbol
  cd perfSymbol
  ~/dotnet3.0-preview9/dotnet publish
  perf record ~/dotnet3.0-preview9/dotnet \
      bin/Debug/netcoreapp3.0/publish/perfSymbol.dll
  ^C
