Linus Torvalds 2baa85d692 ACPI updates for 5.9-rc1
- Eliminate significant AML processing overhead related to using
    operation regions in system memory by reworking the management
    of memory mappings in the ACPI code to defer unmap operations
    (to do them outside of the ACPICA locks, among other things) and
    making the memory operation reagion handler avoid releasing memory
    mappings created by it too early (Rafael Wysocki).
 
  - Update the ACPICA code in the kernel to upstream revision
    20200717:
 
    * Prevent operation region reference counts from overflowing in
      some cases (Erik Kaneda).
 
    * Replace one-element array with flexible-array (Gustavo A. R.
      Silva).
 
  - Fix ACPI PCI hotplug reference counting (Rafael Wysocki).
 
  - Drop last bits of the ACPI procfs interface (Thomas Renninger).
 
  - Drop some redundant checks from the code parsing ACPI tables
    related to NUMA (Hanjun Guo).
 
  - Avoid redundant object evaluation in the ACPI device properties
    handling code (Heikki Krogerus).
 
  - Avoid unecessary memory overhead related to storing the signatures
    of the ACPI tables recognized by the kernel (Ard Biesheuvel).
 
  - Add missing newline characters when printing module parameter
    values in some places (Xiongfeng Wang).
 
  - Update the link to the ACPI specifications in some places (Tiezhu
    Yang).
 
  - Use the fallthrough pseudo-keyword in the ACPI code (Gustavo A. R.
    Silva).
 
  - Drop redundant variable initialization from the APEI code (Colin
    Ian King).
 
  - Drop uninitialized_var() from the ACPI PAD driver (Jason Yan).
 
  - Replace HTTP links with HTTPS ones in the ACPI code (Alexander A.
    Klimov).

Pull power management updates from Rafael Wysocki:
 "The most significant change here is the extension of the Energy Model

  RAPL driver), some new functionality in the existing drivers (eg. a
  new switch to disable/enable CPU energy-efficiency optimizations in
  intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq
  core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci,
  devfreq), including the elimination of W=1 build warnings from cpufreq

Todd Brandt 68f9b22842 pm-graph v5.7 - important s2idle fixes
Important fixes:

 - in s2idle, use timekeeping_freeze trace mark instead of
   machine_suspend to denote entry into s2idle mode.

 - in s2idle, use machine_suspend trace mark to create a new virtual
   device called "s2idle_enter_<n>x". It denotes an s2idle_enter call
   loop of <n> iterations where s2idle was never actually achieved.
   It isn't counted as "freeze time" in the header.

 - in s2idle, only show multiple freeze times if s2idle went in and
   out of resume_noirq. Otherwise multiple freezes are shown with
   "waking" time subtracted (waking time is time spent outside s2idle
   dealing with wakeups).

 - in s2idle summaries, include "FREEZEWAKE" as an issue when at
   least 1ms is spent waking from s2idle. A clean run should only
   wake for the rtc timer.

 - add support for device callbacks with matching names in the same
   phase. In rare cases some devices register multiple callbacks from
   separate drivers using the same name. Without this fix only one is
   shown.

 - add kparamsfmt string back to fix bootgraph

General updates:

 - when suspend_machine is missing, error says "failed in
   suspend_machine"

 - extract target count/time and add to summary title if -multi
   used

 - include any instances of "timeout" in dmesg as issues to be
   logged.

 - fix ftrace parse to handle any number of flags (instead of
   just 4).

 - remove sync/async_device string from device detail, remains in
   hover.

 - when using callgraph (-f) add driver name to callgraph titles.

Alexander A. Klimov fa0866a1d1 cpupower: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Linus Torvalds 355ba37d75 Power management updates for 5.8-rc1
- Rework the system-wide PM driver flags to make them easier to
    understand and use and update their documentation (Rafael Wysocki,
    Alan Stern).
 
  - Allow cpuidle governors to be switched at run time regardless of
    the kernel configuration and update the related documentation
    accordingly (Hanjun Guo).
 
  - Improve the resume device handling in the user space hibernarion
    interface code (Domenico Andreoli).
 
  - Document the intel-speed-select sysfs interface (Srinivas
    Pandruvada).
 
  - Make the ACPI code handing suspend to idle print more debug
    messages to help diagnose issues with it (Rafael Wysocki).
 
  - Fix a helper routine in the cpufreq core and correct a typo in
    the struct cpufreq_driver kerneldoc comment (Rafael Wysocki, Wang
    Wenhu).
 
  - Update cpufreq drivers:
 
    * Make the intel_pstate driver start in the passive mode by
      default on systems without HWP (Rafael Wysocki).
 
    * Add i.MX7ULP support to the imx-cpufreq-dt driver and add
      i.MX7ULP to the cpufreq-dt-platdev blacklist (Peng Fan).
 
    * Convert the qoriq cpufreq driver to a platform one, make the
      platform code create a suitable device object for it and add
      platform dependencies to it (Mian Yousaf Kaukab, Geert
      Uytterhoeven).
 
    * Fix wrong compatible binding in the qcom driver (Ansuel Smith).
 
    * Build the omap driver by default for ARCH_OMAP2PLUS (Anders
      Roxell).
 
    * Add r8a7742 SoC support to the dt cpufreq driver (Lad Prabhakar).
 
  - Update cpuidle core and drivers:
 
    * Fix three reference count leaks in error code paths in the
      cpuidle core (Qiushi Wu).
 
    * Convert Qualcomm SPM to a generic cpuidle driver (Stephan
      Gerhold).
 
    * Fix up the execution order when entering a domain idle state in
      the PSCI driver (Ulf Hansson).
 
  - Fix a reference counting issue related to clock management and
    clean up two oddities in the PM-runtime framework (Rafael Wysocki,
    Andy Shevchenko).
 
  - Add ElkhartLake support to the Intel RAPL power capping driver
    and remove an unused local MSR definition from it (Jacob Pan,
    Sumeet Pawnikar).
 
  - Update devfreq core and drivers:
 
    * Replace strncpy() with strscpy() in the devfreq core and use
      lockdep asserts instead of manual checks for a locked mutex in
      it (Dmitry Osipenko, Krzysztof Kozlowski).
 
    * Add a generic imx bus scaling driver and make it register an
      interconnect device (Leonard Crestez, Gustavo A. R. Silva).
 
    * Make the cpufreq notifier in the tegra30 driver take boosting
      into account and delete an unuseful error message from that
      driver (Dmitry Osipenko, Markus Elfring).
 
  - Remove unneeded semicolon from the cpupower code (Zou Wei).

Srinivas Pandruvada 873e391ff3 tools/power/x86/intel-speed-select: Fix invalid core mask
The core mask display is wrong in some cases. This is showing more
cpus than the mask has. This is because mask is 64 bit but it used
with BIT() macro to get the presence of CPU which doesn't support
unsigned long long. Added a new macro for BIT_ULL and use that
to get the presence of a CPU.

Increase CPU count so that more than 64 is supported in one request.

For example:
sudo ./intel-speed-select -d --cpu 0-66 core-power assoc -clos 0
The above command stops at 63. With this change, it can support more

The 'intel-speed-select -f json perf-profile get-lock-status' command

Commit 74062363f8 ("tools/power/x86/intel-speed-select: Avoid duplicate Package strings for json") prettied this output so that it is a single line for

Output package, die, and cpu info in a single line when using json output.

Since this function was a source of confusion, remove it as it's
just a pointless wrapper.

While at it, rename enable_nonboot_cpus() to thaw_secondary_cpus() to
preserve the naming symmetry.

Srinivas Pandruvada 74062363f8 tools/power/x86/intel-speed-select: Avoid duplicate Package strings for json
For platforms where multiple packages/die, this makes "Package-" key
duplicate. To make unique, add die and cpu id to key name.

So "Package-0" key name will change to "Package-0-die-x:cpu-x".

For example:
$sudo ./intel-speed-select -f json  perf-profile info
Intel(R) Speed Select Technology
Executing on CPU model:106[0x6a]
{
  "package-0:die-0:cpu-0": {
    "perf-profile-level-0": {
      "cpu-count": "32",
      "enable-cpu-count": "32",
...
...
 "package-1:die-0:cpu-16": {

    "perf-profile-level-0": {
      "cpu-count": "32",
      "enable-cpu-count": "32",
      "enable-cpu-mask": "ffff0000,ffff0000",
...
...

For non json format, there is no change. Here when print_package_info()
is called, it will return the level to print for other information.
This level is used formatting. Also in some function duplicate code
was there to print package,die and CPU information. Replace all that
code with a call to print_package_info().

Treat a case when mailbox/mmio command can't be handled by the kernel
drivers when the module is removed or send a command which no driver can

Also when the isst_if_mmio module is removed, we can't send CLOS message
messages via Mailbox on non SKX based platforms. When this module is

Srinivas Pandruvada fb18615828 tools/power/x86/intel-speed-select: Store topology information
Once the CPU is offline, the topology information (core-id, package-id,
die-id) is not accessible via sysfs. So when user selects a config level
more than base config 0 and offlined CPUs to match the config level,
to return to base config he has to manually online CPUs before. Without
this CPUs information mapping from Punit CPU numbering will lot work
as it needs atlest package id for each CPU.

To avoid this additional steps store the topology information in a file
, which is created on the very first run after boot. Since system boots
in base config and all CPUs are online, we can get information about
every CPU.

Once any of the APIs like get_physical_package_id(),
get_physical_core_id() or get_physical_die_id() fails to read from
sysfs, read from the stored mapping file.

This mapping file is stored in /tmp file system. so on every boot
it is recreated to make sure that any new CPUs are added to the
system before boot are taken into account.

But don't use the stored physical device id  when trying to get
information for CPU to send message in for_each_online_package_in_set().
Here use the real value from syfs and in case fails try the next CPU.

Srinivas Pandruvada 3b0fe3bab3 tools/power/x86/intel-speed-select: Avoid duplicate names for json parsing

There are two instances of “speed-select-turbo-freq” underneath
“perf-profile-level-0” for each package. When we load the output into
python with json.load(), the second instance overwrites the first.

Result is that we can only access:
"speed-select-turbo-freq": {
            "bucket-0": {
              "high-priority-cores-count": "2",
              "high-priority-max-frequency(MHz)": "3000",

              "high-priority-max-avx512-frequency(MHz)": "2600"
            },
Because it is a duplicate of "speed-select-turbo-freq": "disabled"
Same is true for "speed-select-base-freq".

Srinivas Pandruvada 78e77b7dfd tools/power/x86/intel-speed-select: Fix result display for turbo-freq auto mode
The turbo-freq enable with auto mode, prints result for the last possible
CPU, which is not correct when either CPU is not present or user wants
command to be limited to a single die/package. For example, in the
below command user wants to limit to die/package 0, but the
"turbo-freq --auto" result is displayed using the other package.

$ sudo intel-speed-select -c 0 turbo-freq enable -a
Intel(R) Speed Select Technology
 package-0
  die-0
    cpu-0
      turbo-freq
        enable:success
 package--1
  die-0
    cpu-31
      turbo-freq --auto
        enable:success

Since we do have to traverse all CPUs, don't display CPU info for
"turbo-freq --auto", as we already displayed the result for
turbo-freq enable with the CPU information.

With the fix, the same command results in:

$ sudo intel-speed-select -c 0 turbo-freq enable -a
Intel(R) Speed Select Technology
package-0
  die-0
    cpu-0
      turbo-freq
        enable:success

Thomas Renninger 41ddb7e1f7 cpupower: Revert library ABI changes from commit ae2917093f
Commit ae2917093f ("tools/power/cpupower: Display boost frequency
separately") modified the library function:

struct cpufreq_available_frequencies
*cpufreq_get_available_frequencies(unsigned int cpu)

to
struct cpufreq_frequencies
*cpufreq_get_frequencies(const char *type, unsigned int cpu)

This patch recovers the old API and implements the new functionality
in a newly introduce method:
struct cpufreq_boost_frequencies
*cpufreq_get_available_frequencies(unsigned int cpu)

This one should get merged into stable kernels back to 5.0 when
the above had been introduced.

Sean Christopherson f6505c88bf tools/x86: Sync msr-index.h from kernel sources
Sync msr-index.h to pull in recent renames of the IA32_FEATURE_CONTROL
MSR definitions.  Update KVM's VMX selftest and turbostat accordingly.
Keep the full name in turbostat's output to avoid breaking someone's
workflow, e.g. if a script is looking for the full name.

While using the renamed defines is by no means necessary, do the sync
now to avoid leaving a landmine that will get stepped on the next time
msr-index.h needs to be refreshed for some other reason.

No functional change intended.

Srinivas Pandruvada 1434a3d357 tools/power/x86/intel-speed-select: Display TRL buckets for just base config level
When only base config level is present, this tool is displaying TRL
(Turbo-ratio-limits) by reading legacy MSR. In this case, also present
core count for TRL by reading MSR 0x1AE.

Srinivas Pandruvada 20183ccd3e tools/power/x86/intel-speed-select: Ignore missing config level
It is possible that certain config levels are not available, even
if the max level includes the level. There can be missing levels in
some platforms. So ignore the level when called for information dump
for all levels and fail if specifically ask for the missing level.

Here the changes is to continue reading information about other levels
even if we fail to get information for the current level. But use the
"processed" flag to indicate the failure. When the "processed" flag is
not set, don't dump information about that level.

Srinivas Pandruvada de7f9d3ddc tools/power/x86/intel-speed-select: Use core count for base-freq mask
Some firmware implementation gives error when a command is sent get mask
for core count 32-61. So use core count to decide.

But there is no function to get core count. So introduce one function to
get core count.

Srinivas Pandruvada 7af5a95bb7 tools/power/x86/intel-speed-select: Support platform with limited Intel(R) Speed Select
There are some platforms, where there limited support of Intel(R) SST
features. Here perf-profile has only one base configuration and limited
support of commands. But still has support for discovery of base-freq and
turbo-freq features. So it is important to show minimum features to use
base-freq and turbo-freq features.

Here the change are:
- When there is no support of CONFIG_TDP_GET_LEVELS_INFO, then instead
of treating this as fatal error, treat this with number of config levels
= 0, that means only base level 0 is present.
- There is no support of mail box commands to get base frequencies or
turbo frequencies. Here present base frequency by reading cpufreq
base freq and turbo frequency by reading MSR 0x1AD.
- Don't display any field, which has value == 0.

Srinivas Pandruvada 21c3390d61 tools/power/x86/intel-speed-select: Use Frequency weight for CLOS
Use different frequency weights for CLOS 0 and and CLOS1-3, to define
relative priority for power budgeting. This will be used for --auto
mode to enable base-freq and turbo-freq feature.
