msobjdump

This tool is used to parse and decompress the executable and linkable format (ELF) files generated by Kernel direct scheduling projects (NPU mode) and standard custom operator projects and simple custom operator projects, and display the result information in a readable format, helping developers obtain the kernel file information.

  • The ELF file is a file format used for binary files, executable files, object code, shared libraries, and core dumps, such as *.a and *.so files. The ELF file structure is as follows:
    • ELF header: describes the structure of the entire file, including the file type, machine type, and version number.
    • Program header table: describes various segments in the file, including information about how a program is loaded to the memory for execution.
    • Section header table: describes the information about each section in the file, including the code, data, and symbol table of the program.
  • If the following faults occur during the use of the tool, analyze and rectify the faults based on the log information:
    • No ELF file is found.
    • The ELF file permission is incorrect.
    • The ELF file exists but cannot be parsed or decompressed.

Tool Installation

  1. Install the msobjdump tool.

    The tool is released with the CANN software package. For details about how to install the CANN software package, see Environment Preparation. The default path is ${INSTALL_DIR}/tools/msobjdump, where Replace ${INSTALL_DIR} with the CANN component directory. For example, if the installation is performed by the root user, the default file storage path is /usr/local/Ascend/cann.

  2. Set environment variables.
    • Install the Ascend-CANN-Toolkit package as the root user: 
      source /usr/local/Ascend/cann/set_env.sh
    • Install the Ascend-CANN-Toolkit package as a non-root user: 
      source ${HOME}/Ascend/cann/set_env.sh
  3. Check whether the tool is successfully installed.
    Run the following command. If --help or -h is displayed, the tool environment is normal and the functions are normal. 
    msobjdump -h

Command

  • Command for parsing the ELF file. 
    msobjdump --dump-elf <elf_file> [--verbose]
    Table 1 Parameters

    Parameter (Case Sensitive)

    Mandatory/Optional

    Description

    --dump-elf <elf_file>, -d

    Yes

    Parses the device information contained in the ELF file, such as the file name, file type, file length, and symbol table, and displays the information on the terminal.

    <elf_file> indicates the path of the ELF file to be parsed, for example, /home/op_api/lib_api.so. Two printing modes are supported:

    • Simple printing: Only some device information is printed by default.
    • Full printing: This mode is used together with --verbose to enable the full device information to be displayed on the screen.

    The fields to be printed vary according to projects. For details, see Table 4 and Table 5.

    --verbose, -V

    No

    This option must be used together with --dump-elf to enable the function of printing full device information in the ELF file.
  • Command for decompressing the ELF file 
    msobjdump --extract-elf <elf_file> [--out-dir <out_path>]
    Table 2 Parameters

    Parameter (Case Sensitive)

    Mandatory/Optional

    Description

    --extract-elf <elf_file>, -e

    Yes

    Decompresses device information contained in the ELF file and flushes the file to the output path based on the original folder rules.

    <elf_file> indicates the path of the ELF file to be decompressed, for example, /home/op_api/lib_api.so.

    • Default path: The decompressed result file is flushed to the current execution path by default.
    • Custom path: The --out-dir field can be used together to set the flushing path.

    --out-dir <out_path>, -o

    No

    This option must be used together with --extract-elf to set the path for flushing the decompressed file.

    <out_path> indicates the directory of the flushed file, for example, /home/extract/.

    NOTE:

    msobjdump can be called by multiple users concurrently. However, users need to specify different --out-dirs. Otherwise, the flushed content may be overwritten.
  • Command for obtaining the list of ELF files 
    msobjdump --list-elf <elf_file>
    Table 3 Parameters

    Parameter (Case Sensitive)

    Mandatory/Optional

    Description

    --list-elf <elf_file>, -l

    No

    Obtains the list of device information files contained in the ELF file and prints the list.

    <elf_file> indicates the path of the ELF file to be printed, for example, /home/op_api/lib_api.so.

Table 6 Kernel type information

KERNEL_TYPE

Description

AICORE

This parameter is reserved and is not supported in the current version.

Only the AI Cores are started during operator execution. For example, if blockdim is set to 5 on the host, 5 AI Cores are started.

AIC

Only the Cube Cores on the AI Cores are started during operator execution. For example, if blockdim is set to 10 on the host, 10 Cube Cores are started.

AIV

Only the Vector Cores on the AI Cores are started during operator execution. For example, if blockDim is set to 10 on the host, 10 Vector Cores are started.

MIX_AIC_MAIN

In the scenario of mixing AIC and AIV, if the kernel function type is set to MIX, the Cube and Vector Cores on the AI Cores are started at the same time during operator execution. For example, you can set blockdim to 10 and task_ration to 1:2 on the host. In this case, 10 Cube Cores and 20 Vector Cores are started.

MIX_AIV_MAIN

In the scenario of mixing AIC and AIV, when multi-core control instructions are used and the kernel function type is set to MIX, the Cube and Vector Cores on the AI Cores are started at the same time during operator execution. For example, you can set blockdim to 10 and task_ration to 1:2 on the host. In this case, 10 Vector Cores and 20 Cube Cores are started.

AIC_ROLLBACK

When the operator is executed, the AI Cores and Vector Cores are started at the same time. In this case, the AI Cores are used as the Cube Cores.

AIV_ROLLBACK

When the operator is executed, the AI Cores and Vector Cores are started at the same time. In this case, the AI Cores are used as the Vector Cores.

Example (Kernel Launch Operator Project)

Take the MatMulInvocationNeo operator (NPU mode) an example. For details about the complete project, see matmul multi-core kernel launch sample. Assume that ${cmake_install_dir} is the root directory of the operator CMake compilation result. The directory structure is as follows (for reference only) and similar to Compiling the CMake Build Configuration File.
