This implements KFD profiling APIs to expose HMM migration and
recoverable page fault profiling data. The ROCm profiler will shared
link with application, to collect and expose the profiling data to
application developers to tune the applications based on how the address
range attributes affect the behavior and performance. Kernel perf and
ftrace requires superuser permission to collect data, it is not suitable
for ROCm profiler.
The profiling data is per process per device event uses the existing SMI
(system management interface) event API. Each event log is one line of
text with the event specific information.
User space usage example for rocm-smi lib and tools under review:
https://github.com/RadeonOpenCompute/rocm_smi_lib/pull/96
v3:
* Changes from Felix's review
v2:
* Keep existing events behaviour
* Use ktime_get_boottime_ns() as timestamp to correlate with other APIs
* Use compact message layout, stick with existing message convention
* Add unmap from GPU event
