1) hipSetDevice sets a flag so that next call to hipCtxGetCurrent returns primary context on current device
2) hipCtxGetCurrent returns primary context on current device if TLS context stack is empty
3) hipCtxPopCurrent falls back to primary context on current device as default
4) hipCtxPushCurrent, hipCtxSetCurrent and hipCtxCreate reset the flag set in hipSetDevice
Associated change is to optimize event recording so it uses
agent-scope releaes (since it was only using system-scope release
to support non-coherent host mem).
Flags and environment variables exist to obtain previous behavior
if desired. Options are documented in new performance guide.
This eliminates host-synchronization for null stream. Instead, the
null-stream uses GPU-side events to wait for other streams.
Default is OFF pending additional testing.
Add enhanced null-stream test.
Also refine HIP_TRACE_API.
1. hipHccModuleLaunchKernel is same as hipModuleLaunchKernel with OpenCL workitem model
2. Added copy right

-
-Contexts across threads are listed under device
-Device reset cleans up all contexts and re-initializes _primaryCtx

1. Added fast math apis for sin, cos, tan, sincos
2. Added test for trig math functions
3. Added logarithm fast math
4. Changed how hipGetDevice, hipDeviceGetCacheConfig emit errors
Change-Id: Ie6ab594ddd5853cbe85e39a2f6d3479a807fa323
1. Changed test macro to emit line numbers
2. Added getcacheconfig api test for nvcc path
3. Fixed hipFuncCache_t data type
TODO: With this commit, right now there are 2 func cache datatypes
a. hipFuncCache_t for runtime API
b. hipFuncCache for driver API
Map these to a single data type
Change-Id: Ia47c9f5d7c2633638051bf17b1103048a1ede973
1. hipDeviceGetLimit API for HCC path is added
2. Test for hipDeviceGetLimit API is added
3. The feature added only supports querying heap size
4. Corrected indents for malloc and free device functions
5. Removed redundant data structures
6. Added g_heap_malloc_size to store the heap size
