AMD ROCm Debugger (ROCgdb) ========================== Introduction ------------ The AMD ROCm Debugger (ROCgdb) is the AMD source-level debugger for Linux, based on the GNU Debugger (GDB). It enables heterogeneous debugging on the AMD ROCm platform comprising of an x86-based host architecture along with commercially available AMD GPU architectures supported by the AMD Debugger API Library (ROCdbgapi). The AMD Debugger API Library (ROCdbgapi) is included with the AMD ROCm release. The current AMD ROCm Debugger (ROCgdb) is an initial prototype that focuses on source line debugging. Symbolic variable debugging capabilities are not currently supported. For more information about AMD ROCm, see: - https://rocmdocs.amd.com/ You can use the standard GDB commands for both CPU and GPU code debugging. For more information about ROCgdb, refer to the *ROCgdb User Guide* which is installed at: - ``/opt/rocm/share/info/gdb.info`` as a texinfo file - ``/opt/rocm/share/doc/gdb/gdb.pdf`` as a PDF file You can refer to the following chapters in the *ROCgdb User Guide* for more specific information about debugging heterogeneous programs on AMD ROCm: - *Debugging Heterogeneous Programs* provides general information about debugging heterogeneous programs. It presents features and commands that are not currently implemented but provisionally planned for future versions. - *Configuration-Specific Information > Architectures > AMD GPU* provides specific information about debugging heterogeneous programs on AMD ROCm with supported AMD GPU chips. This section also lists the implementation status and known issues of the current version. For more information about the GNU Debugger (GDB), refer to the ``README`` file in this folder or check the GNU Debugger (GDB) web site at: - http://www.gnu.org/software/gdb Build the AMD ROCm Debugger --------------------------- ROCgdb can be built on Ubuntu 18.04, Ubuntu 20.04, Centos 8.1, RHEL 8.1, and SLES 15 Service Pack 1. Building ROCgdb has the following prerequisites: 1. A C++11 compiler such as GCC 4.8 or Clang 3.3. 2. AMD Debugger API Library (ROCdbgapi) which can be installed as part of the AMD ROCm release by the ``rocm-dbgapi`` package. 3. For Ubuntu 18.04 and Ubuntu 20.04 the following adds the needed packages: ````shell apt install bison flex gcc make ncurses-dev texinfo g++ zlib1g-dev \ libexpat-dev python3-dev liblzma-dev libgmp-dev libbabeltrace-dev \ libbabeltrace-ctf-dev ```` 4. For CentOS 8.1 and RHEL 8.1 the following adds the needed packages: ````shell yum install -y epel-release centos-release-scl bison flex gcc make \ texinfo texinfo-tex gcc-c++ zlib-devel expat-devel python3-devel \ xz-devel gmp-devel libbabeltrace-devel ncurses-devel wget http://repo.okay.com.mx/centos/8/x86_64/release/libbabeltrace-devel-1.5.4-2.el8.x86_64.rpm \ && rpm -ivh --nodeps libbabeltrace-devel-1.5.4-2.el8.x86_64.rpm ```` 5. For SLES 15 Service Pack 1 the following adds the needed packages: ````shell zypper in bison flex gcc make texinfo gcc-c++ zlib-devel libexpat-devel \ python3-devel xz-devel gmp-devel babeltrace-devel ncurses-devel ```` An example command-line to build ROCgdb on Linux is: ````shell cd rocgdb mkdir build cd build ../configure --program-prefix=roc \ --enable-64-bit-bfd --enable-targets="x86_64-linux-gnu,amdgcn-amd-amdhsa" \ --disable-ld --disable-gas --disable-gdbserver --disable-sim --enable-tui \ --disable-gdbtk --disable-shared --with-expat --with-system-zlib \ --without-guile --with-babeltrace --with-lzma --with-python=python3 make ```` Specify ``--with-rocm-dbgapi=PATH`` if the the AMD Debugger API Library (ROCdbgapi) is not installed in its default location. The ``configure`` script looks in ``PATH/include`` and ``PATH/lib``. The default value for ``PATH`` is ``/opt/rocm``. The built ROCgdb executable will be placed in: - ``build/gdb/gdb`` The texinfo *User Manual* will be placed in: - ``build/gdb/doc/gdb.info`` To install ROCgdb: ````shell make install ```` The installed ROCgdb will be placed in: - ``/bin/rocgdb`` To execute ROCgdb, the ROCdbgapi library and its dependent ROCcomgr library must be installed. These can be installed as part of the AMD ROCm release by the ``rocm-dbgapi`` package: - ``librocm-dbgapi.so.0`` - ``libamd_comgr.so.1`` The PDF *User Manual* can be generated with: ````shell make pdf ```` The generated PDF will be placed in: - ``build/gdb/doc/gdb.pdf`` Disclaimer ---------- The information contained herein is for informational purposes only and is subject to change without notice.
