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
handle. In this case ENOTTY result is returned, so print error.

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
based platform to send via mailbox, other platforms can't use mailbox in

commit fb186158283958984fecf7c1bbc0833dc76e375b upstream

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.

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

increment version number.

commit de7f9d3ddc8c71a116fbdfa298a19abd8d46e696 upstream

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.

commit 7af5a95bb752702bfc91fc513d37f1f799e6fd1f upstream

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.

commit 21c3390d61286912cef312dc4752719142ce0d54 upstream

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.

commit a9b2f8e2fa6c0f791f2345afb826d47c6a0f0e2c upstream

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.
