* In hipFree, if memory is associated with a device, synchronize that device's streams.
This changes the behavior from synchronizing the currently set TLS device.
* All devices sync in hipFree for _appId=-1 case.
* Revert "All devices sync in hipFree for _appId=-1 case."
This reverts commit 1efb34d6a8426661e45bc5f763422a1147aeac10.
* add HIP_SYNC_FREE env var
* reimplement HIP_INIT as a function, expose it as hip_impl::hip_init()
so that it could be called from hipLaunchKernelGGL and other inlined
HIP functions
* Don't call hip_init from ihipPreLaunchKernel
* Initial attempt to switch over to internally linked state.
* Add missing CMake update.
* hipLaunchKernelGGLImpl must be inline as well. Ensure internal linkage.
* Ensure global retrieval uses internally linked state.
* Hide HC in the implementation. Minimise ADL woes.
* Strange software exists, and must be catered to.
* Use a less spammy mechanism for ensuring internal linkage / non-export.
* Remove leftover internal detail.
When shareWithAll memory (e.g., host memory) is allocated, set appId
in hc::AmPointerInfo to -1 to indicate that this memory is not mapped
to any device. Peer checking in ihipStream_t::canSeeMemory is not
necessary if memory is shared with all devices. Thus, it is skipped.
Note that earlier host memory is always mapped to device 0 and HIP
always performs peer checking for all kinds of hipMemcpy. Since the
peer checking process requires context locking, hipMemcpy from/to host
memory always grabs device 0's context lock. Therefore, if there is
another thread holding the context lock of device 0 (e.g.,
hipDeviceSynchronize on device 0), hipMemcpy will have to wait for the
lock until it can actually perform memcpy. This can significantly
deteriorate execution performance.

Logging status of hipCtxSynchronize was missing
Test if hip profiling is active for MARKER_END in ihipPostLaunchKernel
Add MARKER_END after the completion of a kernel launched through
the "grid launch"
Support re-recording of same event by different threads.
- Add criticalData structure to hipEvent_t, similar to mechanism used
for streams, contexts, device. Events are always locked
after streams to avoid deadlock.
- ihipEvent_t::locked_copyCrit can be used to copy critical state
including marker. The critical state in the event can then
be re-recorded.
- refactor hipEventElapsedTime. Remmove stale debug code, native signal
refs.
- Store context inside the tracker rather than using int deviceID that
was always mapped to primary context
- IsPeerWatcher now based on device IDs rather than specific peers.
aligned.
In hcc_am, a bigger buffer will be allocated for alignment purpose
and _unalignedDevicePointer is added in struct AmPointerInfo for
original allocated address.
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.
