Herton R. Krzesinski 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.

Before this patch: turbostat does not recognize value "3" on Ice Lake Xeon

display any package C-states in the results table.

After this patch: turbostat recognizes value 3 on ICX and SPR, treats it as

Huang Rui bf9801baa8 cpupower: Enable boost state support for AMD P-State module
The legacy ACPI hardware P-States function has 3 P-States on ACPI table,
the CPU frequency only can be switched between the 3 P-States. While the
processor supports the boost state, it will have another boost state
that the frequency can be higher than P0 state, and the state can be
decoded by the function of decode_pstates() and read by
amd_pci_get_num_boost_states().

However, the new AMD P-State function is different than legacy ACPI
hardware P-State on AMD processors. That has a finer grain frequency
range between the highest and lowest frequency. And boost frequency is
actually the frequency which is mapped on highest performance ratio. The
similar previous P0 frequency is mapped on nominal performance ratio.
If the highest performance on the processor is higher than nominal
performance, then we think the current processor supports the boost
state. And it uses amd_pstate_boost_init() to initialize boost for AMD
P-State function.

Masahiro Yamada 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.

    PCI BARs on systems where the E820 reservations cover the entire
    PCI host bridge memory window returned by the _CRS object in the
    system's ACPI tables (Hans de Goede).
 
  - Fix and clean up acpi_scan_init() (Rafael Wysocki).
 
  - Add more sanity checking to ACPI SPCR tables parsing (Mark
    Langsdorf).
 
  - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).
 
  - Drop unnecessary "static" from the ACPI PCC address space handling

Merge tag 'acpi-5.17-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more ACPI updates from Rafael Wysocki:
 "The most significant item here is the Platform Firmware Runtime Update
  and Telemetry (PFRUT) support designed to allow certain pieces of the
  platform firmware to be updated on the fly, among other things.

  Also important is the e820 handling change on x86 that should work
  around PCI BAR allocation issues on some systems shipping since 2019.

  The rest is just a handful of assorted fixes and cleanups on top of
  the ACPI material merged previously.

  Specifics:

   - Add support for the the Platform Firmware Runtime Update and
     Telemetry (PFRUT) interface based on ACPI to allow certain pieces
     of the platform firmware to be updated without restarting the
     system and to provide a mechanism for collecting platform firmware
     telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang).

   - Ignore E820 reservations covering PCI host bridge windows on
     sufficiently recent x86 systems to avoid issues with allocating PCI
     BARs on systems where the E820 reservations cover the entire PCI
     host bridge memory window returned by the _CRS object in the
     system's ACPI tables (Hans de Goede).

   - Fix and clean up acpi_scan_init() (Rafael Wysocki).

   - Add more sanity checking to ACPI SPCR tables parsing (Mark
     Langsdorf).

   - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).

   - Drop unnecessary "static" from the ACPI PCC address space handling
     driver added recently (kernel test robot)"

Srinivas Pandruvada 9734213ed4 tools/power/x86/intel-speed-select: Update max frequency
When BIOS disables turbo, the cpuinfo_max_freq will also be same as the
power up base frequency. When SST-PP causes increase in base frequency
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
old base frequency.

Zhang Rui 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.

Chen Yu 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.

Chen Yu 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.

Calvin Walton 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.

Bas Nieuwenhuizen 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.

Len Brown b2b94be787 Revert "tools/power turbostat: adjust for temperature offset"
This reverts commit 6ff7cb371c.

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)
