When SMT is disabled from kernel command line, sibling CPUs still
appears in the sysfs as offline CPUs. This is a problem when turbo-freq
is enabled in auto mode. They are still assigned to CLOS value
of 3 as they are still in the present CPU list. But they are not in the
sibling list of a CPU. When the CPU is a high priority CPU, because of
sibling it will be still set to CLOS to 3 as CLOS is assigned at core
level not at CPU level.
So, avoid setting CLOS 3 to offline CPU.

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

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

scaling_max_freq is still old base frequency, the performance will still

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.

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().

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
turbo-freq --auto

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.

There is an expectation in the CLX platform for SST base-freq feature that
Scaling min frequency be different for high and low priority cores.
This is the way the firmware will understand the priority.
So this change will look at high priority and low priority cores, and set
scaling_min_freq to P1High for high priority cores and P1Low to low
priority cores.

The enable command always returns success, and the disable command always
returns failed because SST-BF cannot be enabled or disabled from the OS on
CascadeLake-N.
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
option reset the setting back to the min frequency.

The current code structure has similar but separate command functions for
the enable and disable operations. This can be improved by adding an int
argument to the command function structure, and interpreting 1 as enable
and 0 as disable. This change results in the removal of the disable
command functions.

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.

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.
