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.

Some strings were missing the human readable form of the error code.
Also unifying source formatting via clang-format.

New environment variable HSA_CU_MASK allows users to
specify a cu mask to every queue allocated from any
GPU. hsa_amd_queue_cu_set_mask is restricted from
escaping this mask.
A new API hsa_amd_queue_cu_get_mask is added to query
the current cu mask.

Under xnack we can now identify the queue which generated a vm fault.
This allows users to identify which queue, and therefore which
dispatch, a vm fault came from.

When no isa's are available no callbacks should be invoked. This
is not an error and should return success.

- Remove gfx800, gfx804 and gfx901 as they do not exist.
- Map the V2 note record of "AMD:AMDGPU:8:0:0" to gfx802 as they are
the same target just connected to a differnt motherboard.
- Correct typo for supporting gfx902:xnack+.
- Support agent names with a minor or stepping version greater than 9.

Add missing target names and make all parts consistent with which
targets are supported.
- Add gfx805 as a supported target.
- Add all ELF targets to genric code.
- Make offline loader match supported targets.

- Make code object reader use mmap when loading from a file on Linux.
- Support computing code object URI for memory either fro the loaded
host executables, or from all mmapped files. Define the environment
variable HSA_LOADER_ENABLE_MMAP_URI to non 0 to search the mmap
files, otherwise only the loaded executables will be seatched.
- For mmap search, determine file size and ommit offset and size URI
fragment when the code object is the whole file even when specifying
a file size explicitly or specifying memory that has been mmaped.
- Always return a non-empty code object URI.
- When a code object reader is created, complete all fields to ensure
it can be used in a multi-threaded manner using only const
operations.
- Add missing exception handlers in the AMD vendor extentions.
- More rigorous checking for errors.

For static linking all non-API functions must have internal linkage
or be in project namespace to avoid colliding with application symbols.
Change-Id: I3398e40a387cca36f3ddef2b978306c765161d72
Adds the following:
- New factory method to create a code object reader from
file with offset and size.
- A pair of queries on a loaded code object to get the URI name/length.
- A bump to the AMD vendor loader extension API and its associated table.

- Correct defintion of HSA_QUEUE_TYPE_COOPERATIVE to be a queue type
and not a bit mask.
- Correct implementation of hsa_queue_type_t to treat is as an
enumeration type and not a bit mask. In particular
HSA_QUEUE_TYPE_COOPERATIVE is a distinct queue type that uses the
multi producer protocol, and is not a bit set value.

Queues should transition to ref counting for all queues eventually.
That cleanup will be part of shared queue pooling support.

Report traps and fatal exceptions through a wavefront's
amd_queue_t.queue_inactive_signal. Previously, only traps were
reported and requireed the compiler to pass in the signal pointer
in s[0:1].
The signal is obtained through a mapping from doorbell index to
amd_queue_t*. The doorbell is fetched within a wavefront through
the gfx9+ S_SENDMSG(MSG_GET_DOORBELL) instruction.

Spec requires GPU release fences and CPU acquire fences at queue destroy.
Also update the recognized status codes.

Corrected semantics used in hsa_queue_load_write_index_relaxed.
The semantics that was used in hsa_queue_load_write_index_relaxed
didn't seem to match the name of the function.
I also removed a useless return keyword.

Remove "zombie" queue state and report queue creation failure via
exceptions. Make Shared object a final container and support array
objects with Shared. Add message printing to hsa_exception in
debug builds.

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)

Added an API for creating signals with attributes.
Added two APIs for IPC operations on signals.
Initial use of exceptions for error handling.
Add ref counting to signals.
Removed spin loops from signal destructors.
Signals are no longer to be destroyed with delete, use DeleteSignal instead.
Added delete safety to doorbells.
Added secondary hsa_signal_t -> Signal* translation path for IPC enabled signals.

When a fatal memory fault occurs the scheduler context-saves all queues
in the process and notifies the runtime through the memory event. The
saved state contains all GPR/LDS data at the moment of the fault.
Retrieve this state and present it to the user if HSA_DEBUG_FAULT is set
to "analyze" and the wavefront caused the fault. If amdgcn-capable objdump
is in the PATH invoke this to disassemble code around the PC.
Queue lifetime is now managed by the runtime to allow querying the
context save state for all active queues.

Note: Implementation same as 1.0 APIs for now.
The followup change will have the complete implementation.
