b2dd71f9f7 tools/power/x86/intel-speed-select: fix build failure when using -Wl,--as-needed
Build of intel-speed-select will fail if you run:

$ LDFLAGS="-Wl,--as-needed" /usr/bin/make V=1
...
gcc -O2 -Wall -g -D_GNU_SOURCE -Iinclude -I/usr/include/libnl3 -Wl,--as-needed -lnl-genl-3 -lnl-3 intel-speed-select-in.o -o intel-speed-select
/usr/bin/ld: intel-speed-select-in.o: in function `handle_event':
(...)/linux/tools/power/x86/intel-speed-select/hfi-events.c:189: undefined reference to `nlmsg_hdr'
...

In this case the problem is that order when linking matters when using
the flag -Wl,--as-needed, symbols not used at that point are discarded.
So since intel-speed-select-in.o comes after, at that point the
libraries/symbols are already discarded and then missing/undefined
references are reported.

To fix this, make sure we specify LDFLAGS after the object file.

display any package C-states in the results table.

5c8166419a kbuild: replace $(if A,A,B) with $(or A,B)
$(or ...) is available since GNU Make 3.81, and useful to shorten the
code in some places.

Covert as follows:

  $(if A,A,B)  -->  $(or A,B)

This patch also converts:

  $(if A, A, B) --> $(or A, B)

Strictly speaking, the latter is not an equivalent conversion because
GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B)
expands to " A", while $(or A, B) expands to "A".

Anyway, preceding spaces are not significant in the code hunks I touched.

When BIOS disables turbo, the cpuinfo_max_freq will also be same as the

the performance will be still limited to the old base frequency as the
cpuinfo_max_freq will not be updated.

In this case we need to update scaling_max frequency to the new
base_frequency. This will result in setting updated max performance
limit in the Pstate driver. So performance will not be limited to the

55279aef75 tools/power turbostat: rename tcc variables
There are two TCC activation temeprature.
One is the default TCC activation temperature, also known as TJ_MAX.
Another one is the effective TCC activation temperature, which is the
subtraction of default TCC activation temperature and TCC offset.

The name of variable tcc_activation_temp might be misleading here.
Thus rename tcc_activation_temp to tj_max, and use tcc_default and
tcc_offset to calculate the effective TCC activation temperature.

No functional change in this patch.

8c69da2930 tools/power turbostat: Enable tsc_tweak for Elkhart Lake and Jasper Lake
It was found that on Elkhart Lake the TSC frequency is driven by
a separate crystal-clock domain, which is different from the
BCLK domain which includes mperf. This has result in small different
speed thus inconsistence between TSC and the mperf, which caused the
Busy% to be higher than 100%. On this platform it seems that the mperf
runs faster than tsc when the CPU is 100% utilized:
delta tsc(18815473183) < delta mperf(18958403680) for 10 seconds.

To align TSC with mperf, leverage the tsc_tweak mechanism introduced for
cores newer than Skylake, so that TSC and mperf would be calculated in
the same domain.

25368d7cef tools/power/turbostat: Remove Package C6 Retention on Ice Lake Server
Currently the turbostat treats ICX the same way as SKX and shares the
code among them. But one difference is that ICX does not support Package
C6 Retention, unlike SKX and CLX.

So this patch:

1. Splitting SKX and ICX in turbostat.
2. Removing Package C6 Rentention for ICX.

And after this split, it would be easier to cutomize Ice Lake Server
in turbostat in the future.

13a779de41 tools/power turbostat: Fix offset overflow issue in index converting
The idx_to_offset() function returns type int (32-bit signed), but
MSR_PKG_ENERGY_STAT is u32 and would be interpreted as a negative number.
The end result is that it hits the if (offset < 0) check in update_msr_sum()
which prevents the timer callback from updating the stat in the background when
long durations are used. The similar issue exists in offset_to_idx() and
update_msr_sum(). Fix this issue by converting the 'int' to 'off_t' accordingly.

301b1d3a91 tools/power/turbostat: Fix turbostat for AMD Zen CPUs
It was reported that on Zen+ system turbostat started exiting,
which was tracked down to the MSR_PKG_ENERGY_STAT read failing because
offset_to_idx wasn't returning a non-negative index.

This patch combined the modification from Bingsong Si and
Bas Nieuwenhuizen and addd the MSR to the index system as alternative for
MSR_PKG_ENERGY_STATUS.

Apparently the TCC offset should not be used to adjust what temperature
we show the user after all.

(on most systems, TCC offset is 0, FWIW)

2af4f9b859 tools/power turbostat: add built-in-counter for IPC -- Instructions per Cycle
Use linux-perf to access the hardware instructions-retired counter.
This is necessary because the counter is not enabled by default,
and also the counter is prone to roll-over -- both of which
perf manages.

It is not necessary to use perf for the cycle counter,
because turbostat already needs to collect delta-aperf
to calcuate frequency.

Add a new command to get and set TRL (Turbo Ratio Limits). This will
help users to get/set TRL, when the direct MSR access is removed.

006050a6bd tools/power/x86/intel-speed-select: Add new command turbo-mode
Add a new command "turbo-mode", which allows to enable/disable
turbo mode globally. This uses base-frequency as the max frequency
when turbo-mode is disabled. This allows soft disable turbo mode
without depending on kernel or BIOS.

7f1b11ba35 tools/power/turbostat: Fallback to an MSR read for EPB
Commit

  6d6501d912a9 ("tools/power/turbostat: Read energy_perf_bias from sysfs")

converted turbostat to read the energy_perf_bias value from sysfs.
However, older kernels which do not have that file yet, would fail. For
those, fall back to the MSR reading.

bbaa2e95e2 tools/power/x86/intel-speed-select: Set higher of cpuinfo_max_freq or base_frequency
In some case when BIOS disabled turbo, cpufreq cpuinfo_max_freq can be
lower than base_frequency at higher config level. So, in that case set
scaling_min_freq to base_frequency.

f981dc171c tools/power/x86/intel-speed-select: Set scaling_max_freq to base_frequency
When BIOS disables turbo, The scaling_max_freq in cpufreq sysfs will be
limited to config level 0 base frequency. But when user selects a higher
config levels, this will result in higher base frequency. But since
scaling_max_freq is still old base frequency, the performance will still
be limited. So when the turbo is disabled and cpufreq base_frequency is
higher than scaling_max_freq, update the scaling_max_freq to the
base_frequency.
