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.

159f130f60 tools/power/x86/intel-speed-select: Fix uncore memory frequency display
The uncore memory frequency value from the mailbox command
CONFIG_TDP_GET_MEM_FREQ needs to be scaled based on the platform for
display. There is no single constant multiplier.

This change introduces CPU model specific memory frequency multiplier.

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.

6c4832253a tools/power/x86/intel-speed-select: Account for missing sysfs for die_id
Some older kernels will not have support to get CPU die_id from the
sysfs. This requires several back ports. But the tool depends on getting
die_id to match to correct CPU.

Relax this restriction and use die_id as 0 when die_id is missing. This
is not a problem as we don't have any multi-die processors with Intel SST
support.

This helps in running this tool on older kernels with just Intel SST
drivers back ported.

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.

864dc09e69 tools/power/x86/intel-speed-select: Max CPU count calculation when CPU0 is offline
Currently /sys/devices/system/cpu/cpu0/topology/thread_siblings is used to
get the max CPU count. But when CPU0 is offline, then this file will be
absent.

So add processing so that we can get count from any first CPU in the
system. which is online.

696691985c tools/power/x86/intel-speed-select: Special handling for CPU 0 online/offline
When "-o" option for force online/offline is used with command:
perf-profile set-config-level

If the config level calls for CPU 0 online/offline, then call fails
as there is special kernel setup required for CPU 0 online/offline
and the currently not setup for that.

But when call is for online CPU 0, then don't fail. Just warn that
this system is not setup for CPU 0 online/offline.

143ad32209 tools/power/x86/intel-speed-select: Enhance core-power info command
In addition to CLOS enable status, also show the core-power feature
status. This will help why clos enable status didn't give desired
results as the core-power feature may be disabled or unsupported.

The new display looks as follows:

$intel-speed-select core-power info
Intel(R) Speed Select Technology
..
 package-0
  die-0
    cpu-0
      core-power
        support-status:supported
        enable-status:enabled
        clos-enable-status:1
        priority-type:0

In the above display "support-status" and "enable-status", shows the
status of the core-power feature and "clos-enable-status", shows the
status of the clos.

f5205f4931 tools/power/x86/intel-speed-select: Make target CPU optional for core-power info
Currently "-c" is a mandatory option for "core-power info" command. Make
this optional as this is a per package/die property. When not specified,
it will print info for every package/die.
