- Leverage managed buffer that would use chunks for fill pattern. Use a
different chunk for the next fill to avoid wait
Change-Id: I254483c867e112f66564ffd8f55e0a605d8896c9
Maintain status of handler callback. For event records we no longer
submit callbacks to reduce the load on the async handler thread. However
without a callback we leak command memory/decrement refcounts. Indicate
status of the handler which we can use to queue a callback when
finish is called.
Change-Id: I89fd02f3d047a0e8162664ee17581a14795f1928
- Queue handler for hipEventRecord(aka marker_ts_) only if there is a
callback associated with it.

Metadata in Codeobject version 5 is the extension of CO3 and CO4.
Add the detection of the new fields and program them in
the setup of the kernel arguments.

Add a state indicator to retain ExternalSignals when needed.
Co-operative group launch uses external signals to indicate a dependency
to the next command.
Change-Id: I6d0daa006e2377c3bbf4aeca0fd5b63c7ac8fbbb
Crash was due to the fact that external signal structure was stale even
after destroyign the command. That is because we skipped wait due to a
missing check.
Detect external signals and dispatch a barrier in ReleaseGpuMemoryFence.
Also clear external_signals_ at ProfilingBegin.

The optimization is controlled with ROCR_SKIP_KERNEL_ARG_COPY.
This is initial check-in for experiments. Extra changes are
necessary for full support:
- handle graph capture with the original sysmem alloc
- avoid memobject references, otherwise there is a race condition with
reusage of the arg buffer
- Remove arg setup from hip
Change-Id: Ib0af710f93e79834711fa4049a7c66093711e68b
The kernel arg pool will be divided into 8 chunks to avoid long stalls,
when the pool will be reused.
Change-Id: I228e6ca1c09e428c1775f1e5b685220a9a5d71af
There is a possible race condition when signal reuse can have
access to a destroyed Timestamp object, because the callback
was running asynchronously. Use reference counter and lock
to allow asynchronous timestamp update
Change-Id: I6224f7c62cb0a03a7466fcc512e5e5afb06736fa
Add ref counting to ProfilingSignal class to track the last release.
If a signal was used in the marker, then don't reuse it,
but create a new one for internal usage.
Don't rely on HSA callback for the command status update if there
are no pending dispatches.
Change-Id: I19f14ed9d80acfe79993b343b2187635f8428a20
Runtime can't assign internal HSA signals for HIP events, because
HIP application can destroy the HIP stream or signal reuse may
occur internally. Switch to global HSA signals for HIP events.
Change-Id: Ieaea2d6b039e492b2e7c5112782a8f4e601e50a1
Add lock protection for signal processing
If signal is reused, then disable reference to it from HIP
Increase the pool signal size to 32
Change-Id: I7d529b35910f83ce577c9eca6d3386759611ccc0
- Create an env var ROC_ACTIVE_WAIT_TIMEOUT to set active wait timeout
- Record profiling informaion if marker_ts_ property is valid.
Change-Id: If0d8aec8d9b0715027cf0f7c3dc8a4c722a6bae6
With HIP API callback runtime has to stall the queue until the
callback is done. Rocclr will introduce SW blocking HSA signal,
which will be released after the callback is done.
Change-Id: I6411f3efab31b468e3b87ebb5c8d155e116b613d
- Make sure barrier with dependent signals issues before queue
index reservation
- Don't issue extra barrier if it's already a barrier command
with dependent signals
Change-Id: I179a8b7adac79eed698f4a4d9eca2606d8e913aa
This addresses the rocprof hang seen with direct dispatch. The
workaround queues the handler back if any of the signal value in the batch
is not decremented. To rememmber the last position in the list, we save
the parsed command in the current timestamp struct.
Change-Id: I02959e463cfe3cee83c54808ffd6e6f48f43b4e8
MT doesn't use GPU waits, but CPU for sync between engines.
Change the threshold values for CPU waits for direct dispatch.
That will bring behavior closer to MT.
Change-Id: Ia41c3cb812614962aff2746b6cf858f1bf77dda2
The copy image workaround could be recursively used by ROCclr blit kernel.
Avoid such situation by using stack variable.
Change-Id: Iadaa8cad9216220194760dd461a9533bb236aea0
- Don't notify if the batch is empty, because that means
the current command was processed already.
- Disable pinning optimization to avoid a race condition on stall.
- TS marker submition requires extra AQL barrier
to track the status.
Change-Id: I17eff4ad12ac66cfe1bb44048bebb1891805279d
GPU waits have noticeable overheads on compute with extra
AQL barrier packet and on SDMA with power saving features. This
change introduces a wait on CPU for 30 us in case the app has tiny
operations.
Change-Id: I761ba3af595f3f48544980058a9077dda15aa5f9
- Avoid GPU wait on the marker submission and update the command
batch after HSA signal callback upon HSA barrier completion.
Change-Id: I5c1c97212aefc2ae4b99aa9e2a81627ee9a38c1c
- The logic will trace compute, sdma read/write operations and
apply signals when necessary
- ROC_CPU_WAIT_FOR_SIGNAL, ROC_SYSTEM_SCOPE_SIGNAL
and ROC_SKIP_COPY_SYNC were added to control the tracking
Change-Id: I9e8e6174c63bf7784f7ab00964e2918c8667d364
- ROCR fails the call for some reason, then the signal will
become invalid and can hang on a wait. The logic will reset the
active signal in such cases
Change-Id: Ia131420200f1bbd7c9a162b8f1b06db8cecf41c6
- There is a performance regression with a HW wait for HSA signal
on ROCr async operation. For now move the logic back to CPU wait.
- Fix profiling issue with multiple HSA signal per single timestamp
object. Some copies require multiple ROCR calls and if profiling is
required, then the execution time is derived from all used signals.
Change-Id: Id003e4abb8c2de378eedc152a7e389500fc6f4ce
Implement the global class for signals tracking per device queue.
Switch to the new tracking mechanism.
Change-Id: I3c4dda04b34e6d18d6a95510d84102909633b415
Use barrier packets for every profile marker that gets submitted
and use the completion signal to get GPU ts. This gives most accurate
dispatch time. Club cache flushes with profile marker if there is a
pending dispatch that needs cache flush. This optimization saves on
extra barrier and helps wall time
Change-Id: Ib62d6d7aabf4743827b561be6c9c5afa813203da
OCL can't distinguish different copy types, but ROC profiler
expects SDMA transfer visibility. Add extra code to detect
a transfer with the host memory and substitute OCL command
