From: Lionel Landwerlin <lionel.g.landwerlin@intel.com>

2 new tests verifying that the OA buffer is properly checked at the
frequency specified by userspace.

v2: (Umesh)
- Capture start_times in test_polling
- Second parameterized test used a 500us hrtimer. Occassionally, this
  timing does not fall within the duration/100 requirement for the time
  spent in kernel. Change this value to 2ms to accommodate all
  platforms.

v3: (Lionel)
- Use NUM_PROPERTIES

Add poll delay parameter to the i915-perf-recorder tool so that the user
can set the frequency of the poll timer that checks for available
reports in the OA buffer.

Couple of nits below.

Either way :

Summary

  **FAILURE**

  Serious unknown changes coming with IGTPW_4304_full absolutely need to be
  verified manually.
  
  If you think the reported changes have nothing to do with the changes
  introduced in IGTPW_4304_full, please notify your bug team to allow them
  to document this new failure mode, which will reduce false positives in CI.

From: Lionel Landwerlin <lionel.g.landwerlin@intel.com>

2 new tests verifying that the OA buffer is properly checked at the
frequency specified by userspace.

v2: (Umesh)
- Capture start_times in test_polling
- Second parameterized test used a 500us hrtimer. Occassionally, this
  timing does not fall within the duration/100 requirement for the time
  spent in kernel. Change this value to 2ms to accommodate all
  platforms.

v3: (Lionel)
- Use NUM_PROPERTIES

v4: (Umesh)
- Update poll parameter name
- Update perf revision check to 5 in new tests
- Fix oa sampling rate message in igt_debug prints
