The PCI ID backup method in rocm_agent_enumerator, where the tool uses lspci to find all AMD GPU devices in the system and manaully match them to gfx version, is extremely outdated. The PCI ID list did not include anything after Vega 10, and the actual call to lspci no longer returned anything due to some missing conversions. The patch adds all GPUs that might be needed by ROCr up through Navy Flounder. The PCI ID to gfx matching pulls from the amdgpu driver and libhsakmt.

rocminfo
ROCm Application for Reporting System Info
To Build
Use the standard cmake build procedure to build rocminfo. The location of ROCM root (parent directory containing ROCM headers and libraries) must be provided as a cmake argument using the standard CMAKE_PREFIX_PATH cmake variable.
After cloning the rocminfo git repo, please make sure to do a git-fetch --tags to get the tags residing on the repo. These tags are used for versioning. For example,
$ git fetch --tags origin
Building from the CMakeLists.txt directory might look like this:
mkdir -p build
cd build
cmake -DCMAKE_PREFIX_PATH=/opt/rocm ..
make
cd ..
Upon a successful build the binary, rocminfo, and the python script, rocm_agent_enumerator, will be in the build folder.
Execution
"rocminfo" gives information about the HSA system attributes and agents.
"rocm_agent_enumerator" prints the list of available AMD GCN ISA or architecture names. With the option '-name', it prints out available architectures names obtained from rocminfo. Otherwise, it generates ISA in one of four different ways:
-
ROCM_TARGET_LST : a user defined environment variable, set to the path and filename where to find the "target.lst" file. This can be used in an install environment with sandbox, where execution of "rocminfo" is not possible.
-
target.lst : user-supplied text file, in the same folder as "rocm_agent_enumerator". This is used in a container setting where ROCm stack may usually not available.
-
rocminfo : a tool shipped with this script to enumerate GPU agents available on a working ROCm stack.
-
lspci : enumerate PCI bus and locate supported devices from a hard-coded lookup table.
