6a8d7fbf1c More ACPI updates for 5.17-rc1
- 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).

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

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.

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.

C-state pre-wake setting[1] is an optimization for some Intel CPUs to
be woken up from deep C-states in order to reduce latency. According to
the spec, the BIT30 is the C-state Pre-wake Disable. Expose this setting
accordingly.
Sample output from turbostat:
...
cpu51: MSR_IA32_POWER_CTL: 0x1a00a40059 (C1E auto-promotion: DISabled)
C-state Pre-wake: ENabled
cpu51: MSR_TURBO_RATIO_LIMIT: 0x2021212121212224

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.

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.

Pull ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to the most recent upstream
  revision including (but not limited to) new material introduced in the
  6.4 version of the spec, update message printing in the ACPI-related
  code, address a few issues and clean up code in a number of places.

  Specifics:

   - Update ACPICA code in the kernel to upstream revision 20210331
     including the following changes:

      * Add parsing for IVRS IVHD 40h and device entry F0h (Alexander
        Monakov).

      * Add new CEDT table for CXL 2.0 and iASL support for it (Ben
        Widawsky, Bob Moore).

      * NFIT: add Location Cookie field (Bob Moore).

      * HMAT: add new fields/flags (Bob Moore).

      * Add new flags in SRAT (Bob Moore).

      * PMTT: add new fields/structures (Bob Moore).

      * Add CSI2Bus resource template (Bob Moore).

      * iASL: Decode subtable type field for VIOT (Bob Moore).

      * Fix various typos and spelling mistakes (Colin Ian King).

      * Add new predefined objects _BPC, _BPS, and _BPT (Erik Kaneda).

      * Add USB4 capabilities UUID (Erik Kaneda).

      * Add CXL ACPI device ID and _CBR object (Erik Kaneda).

      * MADT: add Multiprocessor Wakeup Structure (Erik Kaneda).

      * PCCT: add support for subtable type 5 (Erik Kaneda).

      * PPTT: add new version of subtable type 1 (Erik Kaneda).

      * Add SDEV secure access components (Erik Kaneda).

      * Add support for PHAT table (Erik Kaneda).

      * iASL: Add definitions for the VIOT table (Jean-Philippe
        Brucker).

      * acpisrc: Add missing conversion for VIOT support (Jean-Philippe
        Brucker).

      * IORT: Updates for revision E.b (Shameer Kolothum).

   - Rearrange message printing in ACPI-related code to avoid using the
     ACPICA's internal message printing macros outside ACPICA and do
     some related code cleanups (Rafael Wysocki).

   - Modify the device enumeration code to turn off all of the unused
     ACPI power resources at the end (Rafael Wysocki).

   - Change the ACPI power resources handling code to turn off unused
     ACPI power resources without checking their status which should not
     be necessary by the spec (Rafael Wysocki).

   - Add empty stubs for CPPC-related functions to be used when
     CONFIG_ACPI_CPPC_LIB is not set (Rafael Wysocki).

   - Simplify device enumeration code (Rafael Wysocki).

   - Change device enumeration code to use match_string() for string
     matching (Andy Shevchenko).

   - Modify irqresource_disabled() to retain the resouce flags that have
     been set already (Angela Czubak).

   - Add native backlight whitelist entry for GA401/GA502/GA503 (Luke
     Jones).

   - Modify the ACPI backlight driver to let the native backlight
     handling take over on hardware-reduced systems (Hans de Goede).

   - Introduce acpi_dev_get() and switch over the ACPI core code to
     using it (Andy Shevchenko).

   - Use kobj_attribute as callback argument instead of a local struct
     type in the CPPC linrary code (Nathan Chancellor).

   - Drop unneeded initializatio of a static variable from the ACPI
     processor driver (Tian Tao).

   - Drop unnecessary local variable assignment from the ACPI APEI code
     (Colin Ian King).

   - Document for_each_acpi_dev_match() macro (Andy Shevchenko).

   - Address assorted coding style issues in multiple places (Xiaofei
     Tan).

   - Capitalize TLAs in a few comments (Andy Shevchenko).

   - Correct assorted typos in comments (Tom Saeger)"

 - Updates to the cpupower command to add support for AMD family 0x19
   and cleanup the code to remove many of the family checks to make
   future family updates easier.
 
 - Adding Makefile dependencies for install targets to allow building
   cpupower in parallel rather than serially.

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

  6d6501d912 ("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.

3a3ecfdb60 cpupower: Add cpuid cap flag for MSR_AMD_HWCR support
Remove the family check for accessing the MSR_AMD_HWCR MSR and replace
it with a cpupower cap flag.

This update also allows for the removal of the local cpupower_cpu_info
variable in cpufreq_has_boost_support() since we no longer need it to
check the family.
