If M0[23] is set then the driver will interpret the interrupt as a
debug event, rather than a signal event.
Clear M0 before sending the interrupt. All paths here are terminal so
it's not necessary to save/restore M0.

agentOwner from thunk reflects the GPU which holds the device alias.
We need to return a CPU to better reflect that the memory is system memory.

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.

Assembler toolchains are moving from SP3 to LLVM. Replace trap handler
source code with LLVM equivalent.
Fix a trap issue with SQ_WAVE_IB_STS restore. Mostly harmless as all
traps are currently considered fatal to the wavefront.

CPUClockCounter is not NTP adjusted (CLOCK_MONOTONIC_RAW) so should be
better for measurements. However, it is implemented with syscall while
CLOCK_MONOTONIC is implemented via vDSO. The latency increase becomes
significant when language layers make corresponding clock measurements.
Reverting to CLOCK_MONOTONIC will reduce latency and allow small
duration events to be measured at the cost of incorporating NTP
frequency skew errors. NTP may adjust frequency by 500ppm so limits us
to ~3 decimals in elapsed time.

Description was inconsistent with itself and code. Existing behavior
returns HSA_AMD_MEMORY_POOL_INFO_ACCESSIBLE_BY_ALL == true for system
memory pools only and system memory pools do require hsa_amd_agents_allow_access.

Check if it is true or not. The string() call would define this to an
empty string, which would pass. This would then leave a trailing -
in the version string, which dpkg would error on during package
installation.

Joined threads can not be joined more than once nor can they be detached.
Thread library wait and close allows multiple waits and separate close so
this fixes the pthread implementation.

Small times may be given to time conversion if GPU clocks are used to
accumulate elapsed time. Because HSA APIs deal in absolute time this
leads to large conversion offsets of order system uptime. Variation
in relative clock ratio estimation may be amplified in this case,
destroying elapsed time measurements.
This patch fixes the relative clock ratio used for times which predate
the call to hsa_init. This correlates errors in such times allowing
the elapsed time to be correctly computed.
The effective maximum system uptime before elapsed time conversion becomes
inaccurate is ~3.5 months. GPU event timestamps are good for process uptime
of ~3.5 months. These are limited by double's mantissa precision.

At the moment it is not possible to build ROCr with Clang. This is
a spurious limitation. The present PR addresses it by guarding GCC
only flags and by fixing some additional warnings that Clang triggers;
one of said warnings did outline a rather interesting issue with math
being done on void*s. - AlexVlx
Void ptr arithmetic had already been fixed in amd-master branch.

KFD no longer reports MemoryAccessFault.Failure with retry fault
implementation. ROCr ignores the memory event when Failure = 0.
Use the Flags field instead, which will be non-zero when the
event is triggered.

Makes malloc memory accessible to GPUs so that the memory has the
capabilities of the pool it is locked to.
This admits fine grained locked memory and reserves API space for any future
special CPU pools.
