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
removed,  isst_platform_info.mmio_supported is set to 0. So it can't be
used as a condition to send via mailbox. Here replace check for Skylake

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
For the command
"intel-speed-select perf-profile info":

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".

To avoid this add "-properties" suffix for the second instance to
differentiate.

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

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

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.

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.

It is possible that certain config levels are not available, even

some platforms. So ignore the level when called for information dump

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

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

base freq and turbo frequency by reading MSR 0x1AD.

Janakarajan Natarajan 6af2ed53f0 cpupower: mperf_monitor: Update cpupower to use the RDPRU instruction
AMD Zen 2 introduces the RDPRU instruction which can be used to access some
processor registers which are typically only accessible in privilege level
0. ECX specifies the register to read and EDX:EAX will contain the value read.

ECX: 0 - Register MPERF
     1 - Register APERF

This has the added advantage of not having to use the msr module, since the
userspace to kernel transitions which occur during each read_msr() might
cause APERF and MPERF to go out of sync.

Janakarajan Natarajan 7adafe541f cpupower: mperf_monitor: Introduce per_cpu_schedule flag
The per_cpu_schedule flag is used to move the cpupower process to the cpu
on which we are looking to read the APERF/MPERF registers.

This prevents IPIs from being generated by read_msr()s as we are already
on the cpu of interest.

Ex: If cpupower is running on CPU 0 and we execute

    read_msr(20, MSR_APERF, val) then,
    read_msr(20, MSR_MPERF, val)

    the msr module will generate an IPI from CPU 0 to CPU 20 to query
    for the MSR_APERF and then the MSR_MPERF in separate IPIs.

This delay, caused by IPI latency, between reading the APERF and MPERF
registers may cause both of them to go out of sync.

The use of the per_cpu_schedule flag reduces the probability of this
from happening. It comes at the cost of a negligible increase in cpu
consumption caused by the migration of cpupower across each of the
cpus of the system.

Abhishek Goel d80a4ac208 cpupower : Handle set and info subcommands correctly
Cpupower tool has set and info options which are being used only by
x86 machines. This patch removes support for these two subcommands
from cpupower utility for POWER. Thus, these two subcommands will now be
available only for intel.
This removes the ambiguous error message while using set option in case
of using non-intel systems.

Without this patch on a POWER system:

root@ubuntu:~# cpupower info
System does not support Intel's performance bias setting

root@ubuntu:~# cpupower set -b 10
Error setting perf-bias value on CPU

With this patch on a POWER box:

root@ubuntu:~# cpupower info
Subcommand not supported on POWER

Same result for set subcommand.
This patch does not affect results on a intel box.

Enable command also have support for --auto|-a option, which sets cpufreq
scaling_min to max, so that the high priority base frequency can be the
required minimum for high priority cores. Disable command with -a/--auto

The turbo-freq feature is dependent on the core-power feature. If the

Srinivas Pandruvada a6a82f9bcd tools/power/x86/intel-speed-select: Turbo-freq feature auto mode
Introduce --auto|-a option to turbo-freq enable feature, so that it
does in one step for users who are OK by setting all passed target cores
as high priority and set in CLOS 0 and remaining in CLOS 3. In this way,
users don't have to take multiple steps to enable turbo-freq feature. For
users who want more fine grain control, they can always use core-power
feature to set custom CLOS configuration and assignment.

While here also print the error to output when clos configuration fails.

For example
intel-speed-select -c 0-4 turbo-freq enable --auto

The above command will enable turbo-freq and core-power feature. Also
mark CPU 0 to CPU 4 as high priority.

Introduce --auto|-a option to base-freq enable feature, so that it
does in one step for users who are OK by setting all cores with higher
base frequency to be set in CLOS 0 and remaining in CLOS 3. This option
also sets corresponding clos.min to CLOS 0 and CLOS3. In this way, users
don't have to take multiple steps to enable base-freq feature. For users
who want more fine grain control, they can always use core-power feature
to set custom CLOS configuration and assignment.

Also adjust cpufreq/scaling_min_freq for higher and lower priority cores.

For example user can use:
intel-speed-select base-freq enable --auto

Srinivas Pandruvada b3abfd778b tools/power/x86/intel-speed-select: Fix perf-profile command output
commit "c016ae8f9fa04d361efc8629de49ad3af12b5262
"tools/power/x86/intel-speed-select: Output success/failed for command
output" introduced a regression in perf-profile outputs. With this
the result field is changed to string interpreting every non zero
value as errors. But these commands display on zero (>0) result.
For example before this commit the display was:

package-1
  die-0
    cpu-14
        get-config-levels:4

Here the get-config-levels is interpreted as error and displayed
as error with the above commit:

package-1
  die-0
    cpu-14
        get-config-levels:failed(error 4)

Fix this issue by not using isst_display_result() to display such results,
but define a new function which formats this data and prints.

cpumasks are allocated by calling the alloc_cpu_mask() function and are
never free'd.  They should be free'd after the commands have run.

Fix the memory leaks by calling free_cpu_set().
