Adding a general stage for agents to release their resources on
shutdown. This avoids a circular dependency during shutdown because
we have to delete allocated resources before deleting memory pools, but
we also have to delete memory pools before destroying agents.
The debugger override will set the initial request mask to the
previously set request mask so use a different mask to assert
enablement.
Trap on wave start and end also run back to back, so fix the
previous override mask check as well.
In addition, unlike instruction traps, trap on wave start and end
will not require a rewind of the program counter on wave exit.
In PcSamplingCreateFromId, convert number of bytes into number of
dwords because DmaFill expects a count of 32-bit words, not raw bytes.
This prevents OOB writes on large sampling buffers.
The over arching goal it so provide an API that pre-silicon models can latch into for software bring up.# Please enter the commit message for your changes. Lines starting
Poll the dependent signals twice on all gfx9.0 GPUs except gfx90a.
This is needed as a work-around for a rare issue where SDMA_POLL_REGMEM
may return before the memory is actually cleared.
Resets event_age when signals move. Prior to this PR, event_age
can become unaligned with hsa_event, causing hangs if the event_age
exceeds the true hsa_event age.
For the case parent goes faster then child, and child hasn't call the second
raise(SIGSTOP), then parent's "waitpid(childPid, &childStatus, 0)" will return,
and the childStatus will be 0x137f, which is SIGSTOP signal id.

For the case that the child goes to the second raise(SIGSTOP),
and parent sends PTRACE_CONT, than child exits. Parent will assert at
DeviceSnapshot, as in kfd_ioctl, couldn't get the mm from child pid.

Remove hard assertions for signal validation on hsa_amd_signal_wait_* operations, instead ignore 0/NULL/invalid signals in the dependency condition evaluation to align with HSA specs for barrier-AND and barrier-OR packets.

The scratch_backing_memory_byte_size is not used by CP, but it is
currently used by rocgdb. Putting the field back, but we need to find a
solution for alt_scratch_backing_memory_byte_size.
Also, completely disabling alternate scratch as we need some changes to
support debugger.
The negative queue tests generate an exception which triggers a coredump
generation. Disable RLIMIT so that the coredumps are not generated for
these tests.
Check for RLIMIT_CORE before collecting data for coredump. If the
current limit is 0, then we can return early without spending time
collecting coredump data.
A HSA_IMAGE_ENABLE_3D_SWIZZLE_DEBUG environment flag exists already to
enable/disable this. Default value is false (view3dAs2dArray = 1)
Enabling this flag will enable support for swizzles that do 3D
interleaving on GFX9, GF10 and GFX11. By default support for swizzles that
do 3D interleaving is disabled.
