/* Test Case Description:
Scenario-1: The following function tests the count parameter(last param) to
hipMemRangeGetAttribute api by passing possible extreme values.
Curently the only way to test if count param working properly is to verify
the first parameter of hipMemRangeGetAttribute() api has value 1 stored
Scenario-2: This test case checks the behavior of hipMemRangeGetAttribute() with
AccessedBy flag is consistent with cuda's counter part
Scenario-3: Allocate 4 * page size of memory with the flag hipMemAttachGloal. Advise
AccessedBy, ReadMostly and PreferredLocation to first half(2*pageSz) of the
memory and probe the for the flags which are set earlier using
hipMemRangeGetAttribute() api for the full size(4*PageSz).
Scenario-4: The following scenarios tests that probing the attributes which are not set
by hipMemAdvise() but being probed using hipMemRangeGetAttribute() should
not result in a crash
Scenario-5: The following scenario is a simple test which does the following:
Allocate Hmm memory --> hipMemPrefetchAsync() to device 0 and then
probe LastPrefetchLocation attribute using hipMemRangeGetAttribute
Scenario-6: The following Test Case does negative tests on hipMemRangeGetAttribute()*/
