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
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
lieu of MMIO.

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.

Instead of displaying 0 and 1 for enable status, display "disabled"
and "enabled" respectively.
Similarly for priority type, display "ordered or proportional" instead
of 0 and 1.
An example display:
$intel-speed-select -c 1 core-power info

die-0
cpu-1

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.

We precompute the static-static ECDH during configuration time, in order
to save an expensive computation later when receiving network packets.
However, not all ECDH computations yield a contributory result. Prior,
we were just not letting those peers be added to the interface. However,
this creates a strange inconsistency, since it was still possible to add
other weird points, like a valid public key plus a low-order point, and,
like points that result in zeros, a handshake would not complete. In
order to make the behavior more uniform and less surprising, simply
allow all peers to be added. Then, we'll error out later when doing the
crypto if there's an issue. This also adds more separation between the
crypto layer and the configuration layer.
