Charis Poag b251bb0c9f Rename NPS -> memory partition + compute partition node fix
* Updates:
        - rocm_smi_lib + CLI:
          Rename all "NPS mode" -> "memory partition"
          related files/functions/API/CLI to align with correct
          technical naming
        - rocm_smi_main: fixed identifying primary card's unique id
          utilize rsmi_dev_unique_id_get to map which
          KFD nodes belong to it
        - rsmi_dev_*_partition*: now have better logging output
        - compute partition tests:
          Added 20 sec delay for workaround until GPU
          busy is confirmed as the issue
        - CPPLint fixes/formatting
        - [Example] Moved all endl to "\n" for efficiency
        - [Example] Added Edge & Junction temperature examples
        - [Example] Added rsmi_minmax_bandwidth_get() example - WIP

Charis Poag c3a095a180 [SWDEV-398070] Adding logging to ROCm SMI (by default off)
Updates:
    * [rocm-smi] Provide a thread-safe logging feature
    * [rocm-smi] Adding logrotation into install/upgrade/remove
      scripts
    * [rocm-smi] Updated cmake lists to include rocm_smi_logger
    * [rocm-smi] Updated DEB/RPM install/remove logging file &
      folder with all users having r/w privledges for
      /var/log/rocm_smi_lib/ROCm-SMI-lib.log
    * [rocm-smi] Added ability to do a glob search for multiple files
      (globFileExists), assists doing file searches with * strings
    * [rocm-smi] Added ability to log system details when RSMI_LOGGING
      is turned on (getSystemDetails())
    * [rocm-smi] Added logging to provide which ROCm API is being called
      when RSMI_LOGGING is on
    * [rocm-smi] Added logging to provide SYSFS path and read value,
      when RSMI_LOGGING is on. Provides error reponse on failure.
    * [rocm-smi] Added logging to provide SYSFS path and read value,
      when RSMI_LOGGING is on. Provides error reponse on failure.
    * [rocm-smi] Added environment variable RSMI_LOGGING to control
      when logging is enabled or disabled. By default, by not
      setting this env. variable, logging is turned off. When
      setting RSMI_LOGGING=<any value>, logging is enabled
      which is placed in /var/log/rocm_smi_lib/ROCm-SMI-lib.log file.
      Setting RSMI_LOGGING is allowed in both debug and release builds.
    * [rocm-smi] Removed an initialize procedure which keeps
      debug_inf_loop. Seems this feature is not being used.

      - Confirmed on devices that do not support the API calls, tests pass
    * Updated rocm_smi_test/main.cc
      - Calls new compute partition gtests

Added following updates from review feedback:
   * Updated rocm_smi.h/cc
       - Removed C++ API calls, adding support for both C/C++
         API calls could cause confusion and adds extra work for us
       - rsmi_dev_compute_partition_get -> Fixed an edge case where
         user gives a small buffer length size (smaller than data
         received), but does not receive the partial buffer back.
         google Tests are updated to reflect this find.
   * Updated rocm_smi_example.cc
       - Fixed test_set_freq, issue was that file was not writable.
         We now indicate this warning, so prior errors make sense.
       - General test code cleanup. Removed extra code,
         by creating loops for tests.
   * Updated rocm_smi_main.cc
     - Moved and got rid of an external reference to a map used
       for debugging RSMI enums, now is a const public reference.
   * Updated rocm_smi.py
     - Updated python code to identify NOT_SUPPORTED due to
       (currently) only a few GPU support the feature

Chris Freehill ce475b009c Adjust event counters to report only new events
Previously, RSMI assumed that the event counter values returned
from perf were only new events. But in fact, when we read the
counter values, they are running totals. To account for this, we
now record the value we read and take the difference between the
current value and the previously recorded value.

Chris Freehill ff9546aa62 Don't use hwmon# as indicator of gpu
Previously, during the rsmi_init discovery process, the existence
of an hwmon# directory was used to distinguish between gpus nodes
and non-gpu nodes. This isn't reliable in some scenarios. Instead,
the existence of the vbios_version file is used as an
indicator that the node is indeed a gpu.

Chris Freehill 68095b50e7 Introduce RSMI_DEBUG_INFINITE_LOOP
The environment variable RSMI_DEBUG_INFINITE_LOOP is introduced
to facilitate debugging RSMI in user applications. When this
env. variable is non-zero, an infinite loop will be entered in
rsmi_init(). At this point, a debugger can be attached and RSMI
can be debugger. This only applies to debug builds.
