* Added a new test to verify mutual exclusion of access to device
resources
* Added some missing acquiring of mutexes to some RSMI calls, as
well as try-catch blocks.

* Don't make different shared memory mutexes for different users
* Don't delete (unlink) the shared mutex file if the mutex
initialization fails. This may mess up other processes that
are using it. Instead, print a message on how to resolve the
situation, and then throw an error.
Note, this situation comes up when debug builds (usually)
either assert() or otherwise end execution without a proper
clean up.
* Remove cpplint from shared_mutex code

Given a device index, return the corresponding NUMA node for the
device.
Also, add NUMA node tests to Sys Info Read test.

This solution takes into account that some hwmons use
label files to map sensor types. The previous solution
did not take this into account.

Given a process ID, give the device indices that process is
currently using.
Also:
* made corrections to how RSMI, amdgpu (ie, "card#") and
KFD indicies translate from one another
* add a few missing error codes to rsmi_status_string()
* fix some formatting
Change-Id: Icd2cae66bb4fec768da96af7cf9cf8b8b66ec7f9
Improvements include
* adding additional build flags that warn about stack-smashing
and type conversion errors
* run-time checks for valid function input values and adquate
space for the result of arithmetic operations.
* make sure default case for switch statements do something
besides just assert
* disable using env. var. debugging in release mode
Change-Id: I5f048310c5c56e05d9ec31bcc273404d6a0dd646
* Update doc. on api-support function
* Check for valid integer value when reading a monitor int. val.
* If fan-write test attempts to set speed higher than max.
possible, then skip the test

For device-getter functions, allow users to specify a nullptr
for the provided buffer. In those cases, the function will return
RSMI_STATUS_NOT_SUPPORTED if the hardware or system software does
not support the function. If the function is supported, then
RSMI_STATUS_INVALID_ARGS will be returned, unless a different
error is encountered.
Additionally, tests and documentation were updated to reflect
this change.

Add support and testing for reading the vram vendor associated with
the GPU. The vram vendor can be found as a separate sysfs file at:
/sys/class/drm/card[X]/device/mem_info_vram_vendor
The vram vendor is displayed as a string value.

The new functions added in this commit allow a caller to tell up
front what functions, function variants and monitors are
supported.
Also,
* fixed a few documentation/formatting issues
* fixed a process_info test issue

If the 32-bit domain is found in the kfd node properties for
a device, then it will be used when constructing the bdfid.
If it's not present, it will continue to use the 16 bit version.
Also, whether or not 32b or 16b are used for the domain, the
domain will now be placed in the upper 32b of the 64b bdfid.
* Fixed some unrelated doxygen issues
Change-Id: Icb5116daa1ab45ee305bdbe6cd5df5736dd3ffa3
* Specifically, address case when brand name is longer than buffer
provided
* Also, slightly modify prototype to match similar, existing APIs.
* Address some cpplint issues.

Add support and testing for reading the brand name associated with
a specific GPU (such as mi25, mi50, mi60, etc). The brand name is
associated with the SKU of the GPU, and some brand names can be
mapped from multiple different SKUs.

Also, don't return an error for empty sysfs files. The reserved memory
page file will often have no lines. We don't want it to appear that
this function is not supported if the file is empty.

Add support and testing for reading the Unique ID associated with a
specific GPU. This ID will persist across reboots, even if the GPU is
moved to a different machine. Note that this is per-GPU, not per-card,
as some cards have multiple GPUs, and each GPU will get a unique
identifier
Change-Id: Idce50c6febc2ceb1a4c1200d2489ec8b9d8fe174
* If vendor/device/subsystem name is not found, use device ID string
* Update documentation for get-name functions
* Add support for junction, edge and memory temperature sensors
With newly added initialization parameters that can be

This commit uses a pthread mutex in shared memory to prevent
almost all cases of multiple processes simultaneously
reading/writing to device sysfs files. The main existing race
condition is when 2 processes are starting at the same time,
setting up their shared memory and mutexes. Since this is meant
to prevent collisions among thread and processes, the small
shared memory segments (big enough for a pthread_mutex) will
persist until reboot.
