*Lay foundation to batch packets efficiently for graphs
*Dynamically copy packets with max threshold set with
DEBUG_HIP_GRAPH_BATCH_SIZE, if not stagger packet copy with pow2
*Default threshold for DEBUG_HIP_GRAPH_BATCH_SIZE is 256
*If TS are not collected for a signal for reuse, create a new signal.
This can potentially increase signal footprint if the handler doesn't run
fast enough.
During a process tear-down we wait on all signals before releasing them:
VirtualGPU::HwQueueTracker::~HwQueueTracker() {
for (auto& signal : signal_list_) {
CpuWaitForSignal(signal);
signal->release();
}
[...]
}
In the case where we exit the process after a GPU error that did not
cause an abort (ulimit -c == 0), waiting for the signal can be skipped.
With the device on the error state, no progress is made, and the signal
is probably never going to be modified again:
inline bool WaitForSignal(hsa_signal_t signal, bool active_wait = false, bool yield = false) {
[...]
if (HIP_SKIP_ABORT_ON_GPU_ERROR && amd::Device::IsGPUInError()) {
ClPrint(amd::LOG_ERROR, amd::LOG_SIG,
"Device not Stable, while waiting for Signal ="
"(0x%lx) for %d ns",
signal.handle, kTimeout4Secs);
return true;
}
[...]
}
However, after calling CpuWaitForSignal, when calling "release", we can
end-up on a signal dtor which also tries to wait on the signal. Because
the GPU is the error state, we never receive the signal, and hang the
process during tear down. This happens with the ProfilingSignal dtor:
ProfilingSignal::~ProfilingSignal() {
if (signal_.handle != 0) {
if (hsa_signal_load_relaxed(signal_) > 0) {
LogError("Runtime shouldn't destroy a signal that is still busy!");
if (hsa_signal_wait_scacquire(signal_, HSA_SIGNAL_CONDITION_LT, kInitSignalValueOne,
kUnlimitedWait, HSA_WAIT_STATE_BLOCKED) != 0) {
}
}
hsa_signal_destroy(signal_);
}
}
This dtor should check that the GPU is not in the error state before
trying to wait, which is what this patch implements.

* Fix condition for taking shader path, the size check was moved
incorrectly
* Also account for a bitmask returned for preferred engines
- Refactor deviceLocalAlloc arguments

* Revert "Fix undefined symbol at runtime with newer versions of LLVM (#791)"
This reverts commit b617e8feb6.
* Revert "SWDEV-502579 - Remove duplicated symbols (#21)"
This reverts commit 2296162578.
Revert them because ELF symbols will be added into comgr header.

* SWDEV-465041 - Add support for user events with DD
User events can be replaced with HSA signals. Add the interface
to allocate HSA signal for user events and update the status on
CL_COMPLETE.
Force pinned path with DD to avoid blocking calls. Pinned memory
can be released only when the command is complete.
Simplify device enqueue path to use generic kernel arg buffer and
signals
* Fix notifyCmdQueue() logic for OCL
* Avoid blocking calls in OCL with DD
* Add event destruciton in a case of the failure.

This change ensures that shared memory objects (e.g., files in /dev/shm)
are unlinked once all related IPC events have been destroyed.
[ROCm/clr commit: dc34af61d7]
- When doing device/stream sync, we can submit a handler which may
introduce some host side delays. Use DEBUG_CLR_BATCH_CPU_SYNC_SIZE to
batch commands for host wait. Default for HIP is 8 commands.
- Investigation is underway in ROCr but need to address this for now in
HIP runtime.
[ROCm/clr commit: 9b045922a8]
Init and fini kernel needs to be launched when we load and unload code object. Avoid looping through all kernels within a code object just to run the init and fini kernels. Compiler currently only generates 1 init and fini kernel.
[ROCm/clr commit: cd46294b31]
Remove duplicated compiler symbols from hip-rt. hip-rt should use symbols such as EF_AMDGPU_MACH_AMDGCN_XXX and
ELFABIVERSION_AMDGPU_HSA_VX defined in compiler header.

info_.vgprsPerSimd_
[ROCm/clr commit: 397f303d97]
- Currently runtime just uses the local agent as it did not check for
IPCShared()
- With this fix we query hsa_amd_pointer_info and get the right agent
for the memory to pass it to the HSA copy api
