Hygon Family 18h(Dhyana) support RAPL in bit 14 of CPUID 0x80000007 EDX,
and has MSRs RAPL_PWR_UNIT/CORE_ENERGY_STAT/PKG_ENERGY_STAT. So add Hygon

In some case C1% will be wrong value, when platform doesn't have MSR for
C1 residency.
For example:
Core CPU CPU%c1
- - 100.00
0 0 100.00
0 2 100.00
1 1 100.00
1 3 100.00
But adding Busy% will fix this
Core CPU Busy% CPU%c1
- - 99.77 0.23
0 0 99.77 0.23
0 2 99.77 0.23
1 1 99.77 0.23
1 3 99.77 0.23
This issue can be reproduced on most of the recent systems including
Broadwell, Skylake and later.
This is because if we don't select Busy% or Avg_MHz or Bzy_MHz then
mperf value will not be read from MSR, so it will be 0. But this
is required for C1% calculation when MSR for C1 residency is not present.
Same is true for C3, C6 and C7 column selection.
So add another define DO_BIC_READ(), which doesn't depend on user
column selection and use for mperf, C3, C6 and C7 related counters.
So when there is no platform support for C1 residency counters,
we still read these counters, if the CPU has support and user selected
display of CPU%c1.

Turbostat works by taking a snapshot of counters, sleeping, taking another
snapshot, calculating deltas, and printing out the table.
The sleep time is controlled via -i option or by user sending a signal or a
character to stdin. In the latter case, turbostat always adds 1 ms
sleep before it reads the counters, in order to avoid larger imprecisions
in the results in prints.
While the 1 ms delay may be a good idea for a "dumb" user, it is a
problem for an "aware" user. I do thousands and thousands of measurements
over a short period of time (like 2ms), and turbostat unconditionally adds
a 1ms to my interval, so I cannot get what I really need.
This patch removes the unconditional 1ms sleep. This is an expert user
tool, after all, and non-experts will unlikely ever use it in the non-fixed
interval mode anyway, so I think it is OK to remove the 1ms delay.

Commit '47936f944e78 tools/power turbostat: fix printing on input' make
a valid fix, but it completely disabled piped stdin support, which is
a valuable use-case. Indeed, if stdin is a pipe, turbostat won't read
anything from it, so it becomes impossible to get turbostat output at
user-defined moments, instead of the regular intervals.
There is no reason why this should works for terminals, but not for
pipes. This patch improves the situation. Instead of ignoring pipes, we
read data from them but gracefully handle the EOF case.

Turbostat currently normalizes TSC and other values by dividing by an
interval. This interval is the delta between the start of one global
(all counters on all CPUs) sampling and the start of another. However,
this introduces a lot of jitter into the data.
In order to reduce jitter, the interval calculation should be based on
timestamps taken per thread and close to the start of the thread's
sampling.
Define a per thread time value to hold the delta between samples taken
on the thread.
Use the timestamp taken at the beginning of sampling to calculate the
delta.
Move the thread's beginning timestamp to after the CPU migration to
avoid jitter due to the migration.
Use the global time delta for the average time delta.

The -w argument in x86_energy_perf_policy currently triggers an
unconditional segfault.
This is because the argument string reads: "+a:c:dD:E:e:f:m:M:rt:u:vw" and
yet the argument handler expects an argument.
When parse_optarg_string is called with a null argument, we then proceed to
crash in strncmp, not horribly friendly.
The man page describes -w as taking an argument, the long form
(--hwp-window) is correctly marked as taking a required argument, and the
code expects it.
As such, this patch simply marks the short form (-w) as requiring an
argument.

Compiling without optimisations is silly, especially since some

x86_energy_perf_policy first uses __get_cpuid() to check the maximum
CPUID level and exits if it is too low. It then assumes that later
calls will succeed (which I think is architecturally guaranteed). It
also assumes that CPUID works at all (which is not guaranteed on
x86_32).
If optimisations are enabled, gcc warns about potentially
uninitialized variables. Fix this by adding an exit-on-error after
every call to __get_cpuid() instead of just checking the maximum
level.

A lot of tests reuse $DEV1 veth name for naming dummy device. This causes
problem when tdc is invoked without specifying a test group and tries to
execute all tests. In this case tdc instantiates ns plugin, which creates
veth pair once before running tests. However, if any of the tests that
reuse $DEV1 run before test that depend on ns plugin, it will delete $DEV1
as a part of teardown section:

Add test cases for devlink-trap on top of the netdevsim implementation.
The tests focus on the devlink-trap core infrastructure and user space
API. They test both good and bad flows and also dismantle of the netdev
and devlink device used to report trapped packets.
This allows device drivers to focus their tests on device-specific
functionality.

Dan reported:
The patch acda655fefae: "selftests: Add nettest" from Aug 1, 2019,
leads to the following static checker warning:
./tools/testing/selftests/net/nettest.c:1690 main()
warn: unsigned 'tmp' is never less than zero.
./tools/testing/selftests/net/nettest.c
1680 case '1':
1681 args.has_expected_raddr = 1;
1682 if (convert_addr(&args, optarg,
1683 ADDR_TYPE_EXPECTED_REMOTE))
1684 return 1;
1685
1686 break;
1687 case '2':
1688 if (str_to_uint(optarg, 0, 0x7ffffff, &tmp) != 0) {
1689 tmp = get_ifidx(optarg);
1690 if (tmp < 0) {
"tmp" is unsigned so it can't be negative. Also all the callers assume
that get_ifidx() returns negatives on error but it looks like it really
returns zero on error so it's a bit unclear to me.
Update get_ifidx to return -1 on errors and cleanup callers of it.
