Use mwaitx instructions when busy waiting for signals to reduce CPU
energy usage.
This can be disabled by setting HSA_ENABLE_MWAITX=0

ROCr internally uses the same allocation_map_ list to track memory
allocations that are both for internal allocations and allocations by
users of ROCr library. In some edge cases, the library user would call
hsa_amd_pointer_info on an invalid pointer, but ROCR would return the
pointer as valid because this pointer belongs to a memory range that
was allocated internally within ROCr. Adding a flag to differentiate
between internal and external allocations.

Amount of memory requested by user may be aligned-up internally to
the memory pool granularity. The extra padded memory should not be
considered when validating pointers from the user. Also return the
user requested size when user queries pointer information.

Mostly a demo at this point. Logs SVM (aka HMM) info to
HSA_SVM_PROFILE if set.

IPC use cases with RVD set can't convey proper agent handles.
Runtime discovery is required to properly route the copy in this
case.

Prior solution used a single global lock to protect the memory tracking structures.
This change protects the memory tracking structure with a shared mutex (rw lock) in
shared (r) mode for memory allocations and frees so that long duration processes,
calling to kfd, can be done in parallel. Operations which must modify the memory map
take the mutex in exclusive mode (w) and must not call to the thunk while holding
the mutex.
The fragment allocator now requires separate protection and is protected with a
mutex at the device level. Protecting at the device level, rather than pool,
allows retention of the current recursive design and allows calling Trim from
withing Allocate. This could be made finer (pool level locks) but would
require backing out of Allocate entirely to call Trim. Trim and any retried
Allocation must be done in isolation (per device) or we may report OOM when
memory is actually available in some pool's fragment cache. So some device
level serialization is required in at least some paths.

Take in const void* rather than void*. This does not break the
abi or existing code. Existing code would need to cast away any
const which is unnecessary and annoying.

Sramecc is misreported in kfd 4.0 and prior. To prevent possible
corruption due to d16 instructions, deny use of gfx906 with older
kfds and correct misreport for gfx908. Denial of gfx906 may be
overridden by setting HSA_IGNORE_SRAMECC_MISREPORT=1.

Adds hsa_amd_register_deallocation_callback and hsa_amd_deregister_deallocation_callback
to notify when HSA memory has been released.

Also rename blit_agent to region_gpu and add comments to clarify
its role in deprecated region API support rather than to do blits.

Debug agent requires handles to internal queues for single step debugging.
Added tools only API hsa_amd_runtime_queue_create_register for reporting.
hsa_amd_runtime_queue_create_register sets a callback which is invoked
when internal queues are created.

Apertures now overlap with the change to 48bit addressing which
precludes using aperture checks to discover buffer ownership.
Switches to ptrinfo to decide which device a buffer owned by.
This corrects faults in the legacy hsa_memory_copy api.
Change-Id: I5c7ce0216e1cdc96f836fc6fec9c3defdf4b9d90
1/ Revised debug event handler to handle different events.
2/ Added queue error handler using the callback in queue create, which will print out wave info when queue in error state.
3/ Preempt queue instead of destory queue when queue error state.

1. Add hsa ext api hsa_amd_register_vmfault_handler for debugger to register callback in case of VM fault.
2. Extend hsa_ven_amd_loader API to:
(1) iterate loaded code objects in executable:
hsa_ven_amd_loader_executable_iterate_loaded_code_objects
(2) get loaded code object info:
hsa_ven_amd_loader_loaded_code_object_get_info
3. Make the id of hsa_queue the same as the one used in communication with thunk (for amd_aql_queue)

On multi-node systems only the first CPU node was recognized in the
signal consumer list, causing fallback to non-interrupt signals.

Querying HSA_AMD_AGENT_MEMORY_POOL_INFO_LINK_INFO between a gpu agent
and its own local memory pool returns a wrong information.
Fix: return link with 0 hop count.
