- Validate compile-time disables.
- Add README.md section explain how to install/use CodeXL tracing
- Add code docs on trace_helper.h
- fix color on hipLaunchKernel to green.
[ROCm/clr commit: fa8deac1ad]
- Creates markers in HIP group and they show up in CodeXL trace
- Marker text includes HIP functioin arguments
- (Add trace_helper to convert arguments to strings)
- Still need to add HIP_INIT_API for ~30 HIP functions.
[ROCm/clr commit: 54704b59dd]
Note hipHostMalloc (not hipHostAlloc or hipMallocHost).
- the hipHost* is used for all HIP APIs dealing with Host memory.
(including hipHostMalloc, hipHostFree, hipHostRegister,
hipHostUnregister, hipHostGetFlags, hipHostGetDevicePointer).
- hipMallocHost is consistent with "hipMalloc" for allocating device
memory. Enumerations hipHostMalloc* also used as optional
flags parm to hipHostMalloc.
[ROCm/clr commit: 2d0fade1f7]
- move waitAllStreams to device member function.
- create separate stream member function for copyAsync, like copySync.
hipMemcpyAsync now calls the copyAsync.
[ROCm/clr commit: a88c2b1ec9]
- NULL stream was waiting for itself to be empty before each command.
- Force "blocking" streams to wait for NULL to empty. This was missing
before.
- async copy was disabling itself via trueAsync=false for common cases.
Refactor:
- rename _null_stream to _default_stream.
- move some null sync function to defaultSync, move to dev member func.
[ROCm/clr commit: 44522eb607]
-Move staging buffer locks inside the staging buffer code.
-Remove dedicated per-device completion_signal + per-device lock -
instead allocated signal from the per-stream pool. This elimintes
the lock and allows more concurrency.
-remove switch HIP_DISABLE_BIDIR_MEMCPY
[ROCm/clr commit: e64174f47a]
- refactor staging buffer to operate on hsa* data structures not
hc::accelerator.
- use hsa_memory_allocate to allocate staging buffers rather than
am_alloc.
- Refactor device reset with single member function. Don't reallocate
staging buffers on reset.
- Properly track dependencies based on command type. Add new deps for
H2D and D2D rather than overloading H2D.
[ROCm/clr commit: 3b45e064f9]
Still #include staging_buffer.cpp into hip_hcc.cpp.
Directed tests compile hip_hcc to static library and use the library.
[ROCm/clr commit: a1879ba59b]
- Control with HIP_DB=mask (env var). See src/hip_hcc.cpp for mask
values:
#define DB_API 0 /* 0x01 - shortcut to enable HIP_TRACE_API on single switch */
#define DB_SYNC 1 /* 0x02 - trace synchronization pieces */
#define DB_MEM 2 /* 0x04 - trace memory allocation / deallocation */
#define DB_COPY1 3 /* 0x08 - trace memory copy commands. . */
#define DB_SIGNAL 4 /* 0x10 - trace signal pool commands */
- Combine with HIP_TRACE to see debug with API trace.
- Use colors to distinguish different flows of debug.
- Add define COMPILE_DB_TRACE to allow removing all debug at compile-time
[ROCm/clr commit: 9b1b108ea8]
In this change, the cpu memcpy will wait until all the commands in the current stream are done.
Note that, it only waits on current stream. But not on other streams.
[ROCm/clr commit: a845dccfef]
Add dependency for host-to-host copy.
Add debug mode for HIP_DISABLE_HW_COPY_DEP and
HIP_DISABLE_HW_KERNEL_DEP - setting these to -1 now ignores
all dependencies.
