AMD Debugger API (ROCdbgapi)
============================
Introduction
------------
The AMD Debugger API is a library that provides all the support necessary for a
debugger and other tools to perform low level control of the execution and
inspection of execution state of AMD's commercially available GPU architectures.
For more information about the AMD ROCm ecosystem, see:
- https://rocmdocs.amd.com/
Build the AMD Debugger API Library
----------------------------------
The ROCdbgapi library can be built on Ubuntu 18.04, Ubuntu 20.04, Centos 8.1,
RHEL 8.1, and SLES 15 Service Pack 1.
Building the ROCdbgapi library has the following prerequisites:
1. A C++17 compiler such as GCC 7 or Clang 5.
2. AMD Code Object Manager Library (ROCcomgr) which can be installed as part of
the AMD ROCm release by the ``comgr`` package.
3. ROCm CMake modules which can be installed as part of the AMD ROCm release by
the ``rocm-cmake`` package.
4. For Ubuntu 18.04 and Ubuntu 20.04 the following adds the needed packages:
````shell
apt install gcc g++ make cmake doxygen graphviz texlive-full
````
NOTE: The ``doxygen`` 1.8.13 that is installed by Ubuntu 18.04 has a bug
that prevents the PDF from being created. ``doxygen`` 1.8.11 can be built
from source to avoid the issue.
5. For CentOS 8.1 and RHEL 8.1 the following adds the needed packages:
````shell
yum install -y gcc gcc-g++ make cmake doxygen graphviz texlive \
texlive-xtab texlive-multirow texlive-sectsty texlive-tocloft \
texlive-tabu texlive-adjustbox
````
NOTE: The ``doxygen`` 1.8.14 that is installed by CentOS 8.1 and RHEL 8.1,
has a bug that prevents the PDF from being created. ``doxygen`` 1.8.11 can be
built from source to avoid the issue.
6. For SLES 15 Service Pack 15 the following adds the needed packages:
````shell
zypper in gcc gcc-g++ make cmake doxygen graphviz texlive-scheme-medium \
texlive-hanging texlive-stackengine texlive-tocloft texlive-etoc \
texlive-tabu
````
An example command-line to build the ROCdbgapi library on Linux is:
````shell
cd rocdbgapi
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../install ..
make
````
You may substitute a path of your own choosing for ``CMAKE_INSTALL_PREFIX``.
The built ROCdbgapi library will be placed in:
- ``build/include/amd-dbgapi.h``
- ``build/librocm-dbgapi.so*``
An example command-line to generate the HTML and PDF library documentation is:
````shell
make doc
````
The generated ROCdbgapi library documentation is put in:
- ``doc/html/index.html``
- ``doc/latex/refman.pdf``
To install the ROCdbgapi library and documentation:
````shell
make install
````
The installed ROCdbgapi library and documentation will be placed in:
- ``../install/include/amd-dbgapi.h``
- ``../install/lib/librocm-dbgapi.so*``
- ``../install/share/amd-dbgapi/LICENSE.txt``
- ``../install/share/amd-dbgapi/README.md``
- ``../install/share/html/amd-dbgapi/index.html``
- ``../install/share/doc/amd-dbgapi/amd-dbgapi.pdf``
To use the ROCdbgapi library, the ROCcomgr library must be installed. This can
be installed as part of the AMD ROCm release by the ``comgr`` package:
- ``libamd_comgr.so.1``
The ROCdbgapi library requires that the ROCr library is loaded in the inferior
to enable AMD GPU debugging. This can be installed as part of the AMD ROCm
release by the ``hsa-rocr-dev`` package:
- ``libhsa-runtime64.so.1 ``
Running the AMD Debugger API Library
------------------------------------
The AMD Debugger API library has an optional runtime dependency to the
`amdgpu.ids` database file, located in `/opt/amdgpu/share/libdrm/amdgpu.ids`
or `/usr/share/libdrm/amdgpu.ids`.
The `/opt/amdgpu/share/libdrm/amdgpu.ids` database is provided by the
`libdrm-amdgpu-common` ROCm package on all distributions.
The `/usr/share/libdrm/amdgpu.ids` is provided by the following packages:
- SLES: `libdrm-amdgpu`
- RHEL: `libdrm`
- Debian and Ubuntu: `libdrm-common`
Known Limitations and Restrictions
----------------------------------
You can refer to the following sections in the *AMD Debugger API Specification*
documentation for:
- *Supported AMD GPU Architectures* provides the list of supported AMD GPU
architectures.
- *Known Limitations and Restrictions* provides information about known
limitations and restrictions.
The ROCdbgapi library is compatible with the following interface versions:
- *AMD GPU Driver Version*
- See ``KFD_IOCTL_MAJOR_VERSION`` and ``KFD_IOCTL_MINOR_VERSION`` in
``src/linux/kfd_ioctl.h`` which conform to [semver](http://semver.org/).
- *AMD GPU Driver Debug ioctl Version*
- See ``KFD_IOCTL_DBG_MAJOR_VERSION`` and ``KFD_IOCTL_DBG_MINOR_VERSION`` in
``src/linux/kfd_ioctl.h`` which conform to [semver](http://semver.org/).
- *ROCm Runtime r_debug ABI Version*
- See ``ROCR_RDEBUG_VERSION`` in ``src/rocr_rdebug.h``.
- *Architectures and Firmware Versions*
- See ``s_gfxip_lookup_table`` in ``src/os_driver.cpp``.
