Siu Chi Chan bff8e15e13 Fix C-style hipLaunchKernel (#1835)
* Fix bug in LaunchKernel test
Instead of passing the address of the gpu buffer, pass the address
of the pointer that holds the address of the gpu buffer

* Fix hipLaunchKernel's kernarg buffer construction.
The hipLaunchKernel implementation should rely on ihipModuleLaunchKernel
to construct the kernarg buffer correctly based on kernel metadata.

* Fix a bug in get_functions where the Kernel_descriptor wasn't constructed with the correct kernarg layout information.

* Fix a bug in kernarg layout parsing dealing with kernel without any arg

* teach ihipModuleLaunchKernel to handle kernel without any arg

* Add a more interesting test

Evgeny Mankov 2735b9923f Merge pull request #1700 from scchan/object_load_error_check
add error checking for code object loading

Siu Chi Chan 6613a37b3b Fix associate code object symbols with host allocation bug (#1799)
The current implementation skips this procedure for a given device
object when a global symbol is found in the cache.  This is incorrect:

 - There could be other undefined globals that have not been previously
encountered further down the list
 - If a symbol is found in the cache, it doesn't need to be pinned again
but it still need to be defined for the current executable

Added special case for the printf buffer symbol (already pinned by HCC)

The bug was exposed by running printf on different GPUs.

Laurent Morichetti 91748f4e6c Addressed review comments
Change comment "must exceed" to "must be no shorter than"
move the std::string instead of creating a copy

Laurent Morichetti 7473140a76 Fix a code object memory corruption
The lifetime of the buffer given to
hsa_code_object_reader_create_from_memory must exceed that of the
code object reader. We need to create a copy of the code object
binary memory (file) that is kept allocated until the code object
reader is destroyed.

Aryan Salmanpour 034201f658 [hip] fix a bug where we parse kernel's arguments layout for a given kernel multiple times (#1232) 2019-07-17 07:29:07 +00:00
Aaron Enye Shi 77bef86949 Fix dlpi_name info empty when using GCC on ub18 (#1181)
This fixes a bug where GCC++ on Ubuntu 18.04 creates failing executables compared to GCC++ on 16.04 and clang++. While creating function names on Ubuntu 18.04, dl_phdr_info seems to provide a non-zero value for dlpi_addr on initial iteration, and an empty string in dlpi_name. This is causing failure when linking with g++, since the empty string prevents the kernel function from being loaded. Clang++ and GCC on UB16 provide a zero value for dlpi_addr. To fix this, we need to verify both addr and name exists, so that /proc/self/exe can be properly loaded.

Laurent Morichetti 73f931bdbd Add support for code object v3
Use the code object manager library to parse the code object metadata. Both
code object v2 and v3 formats are now supported for HCC generated binaries.

This reverts commit a3d118eaa8.

* Revert "Use COMgr to read Kernel Args Metadata (#1006)"

This reverts commit 8a548bf40b.

* Revert "improve program state commentary"

This reverts commit 7aada87cbd.

* Revert "load program state once per agent"

This reverts commit c9117de8eb.

* start moving function_names() into the hip shared lib

* start moving code_object_blobs to a new "state" object

* Consolidate various program state related static objects into a
single program_state object

* minor clean up

* move more stuffs from functional_grid_launch into program_state

* clean up old code for kernarg size and alignment

* update hip_module to use newer api in program_state

* Create public member functions for program_state

* move most program state functions into shared library

* Pass the data buffer size to load_executable
Otherwise, it can't figure what the data size is
just from the char* (since the data is not really a string)

* turning free functions in program state into members of program_state_impl

* change the free function globals() into a member of program_state_impl

* replace the static mutex used for populating globals

* moving associate_code_object_symbols_with_host_allocation into
program_state_impl

* move load_code_object_and_freeze_executable into program_state_impl

* moving executables and functions_names into program_state_impl

* moving kernels() into program_state_impl

* moving functions() into program_state_impl

* fixing/cleaning up some header file includes

* moving member function for kernargs_size_align into program_state.cpp

* moving Kernel_descriptor into program_state.inl

* add a new class to manage agent globals

* moving all agent globals processing functions into agent_globals_impl

* load program state once per agent

re-merging PR991 against other program state changes

* fix per-agent program state member initialization

* cache executables based on elf name, isa, and agent.

This avoids program state reloading executables after a shared library is dlopened.

re-merging PR1057 against other program state changes

* protect executables cache by a global mutex

* return ref to executables cache

* adapt PR#981 Make hipModuleGetGlobal be in HIP runtime
