ROCm is focused on using AMD GPUs to accelerate computational tasks, such as machine learning, engineering workloads, and scientific computing. In order to focus our development efforts on these domains of interest, ROCm
Because the ROCm Platform has a focus on particular computational domains, we offer official support for a selection of AMD GPUs that are designed to offer good performance and price in these domains.
ROCm officially supports AMD GPUs that have use following chips:
- GFX8 GPUs
- "Fiji" chips, such as on the the AMD Radeon R9 Fury X and Radeon Instinct MI8
- "Polaris 10" chips, such as on the AMD Radeon RX 580 and Radeon Instinct MI6
- "Polaris 11" chips, such as on the AMD Radeon RX 570 and Radeon Pro WX 4100
- GFX9 GPUs
- "Vega 10" chips, such as on the AMD Radeon Radeon RX Vega 64 and Radeon Instinct MI25
ROCm is a collection of software ranging from drivers and runtimnes to libraries and developer tools. Some of this software may work with more GPUs than the "officially supported" list above, though AMD does not make any official claims of support for these devices on the ROCm software platform. The following list of GPUs are likely to work within ROCm, though full support is not guaranteed:
- GFX7 GPUs
- "Hawaii" chips, such as the AMD Radeon R9 390X and FirePro W9100
As described in the next section, GFX8 GPUs require PCIe gen 3 with support for PCIe atomics. This requires both CPU and motherboard support. GFX9 GPUs, by default, also require PCIe gen 3 with support for PCIe atomics, but they can operate in most cases without this capability.
At this time, the integrated GPUs in AMD APUs are not officially supported targets for ROCm.
For a more detailed list of hardware support, please see the following documentation.
As described above, GFX8 and GFX9 GPUs require PCI Express 3.0 with PCIe atomics in the default ROCm configuration. In particular, the CPU and every active PCIe point between the CPU and GPU require support for PCIe gen 3 and PCIe atomics. The CPU root must indicate PCIe AtomicOp Completion capabilities and any intermediate switch must indicate PCIe AtomicOp Routing capabilities.
Current CPUs which support PCIe Gen3 + PCIe Atomics are:
- AMD Ryzen CPUs;
- AMD Ryzen APUs;
- AMD Ryzen Threadripper CPUs
- AMD EPYC CPUs;
- Intel Xeon E7 v3 or newer CPUs;
- Intel Xeon E5 v3 or newer CPUs;
- Intel Xeon E3 v3 or newer CPUs;
- Intel Core i7 v4, Core i5 v4, Core i3 v4 or newer CPUs (i.e. Haswell family or newer).
- Some Ivy Bridge-E systems
Beginning with ROCm 1.8, we have relaxed the requirements for PCIe Atomics on GFX9 GPUs such as Vega 10. We have similarly opened up more options for number of PCIe lanes. GFX9 GPUs can now be run on CPUs without PCIe atomics and on older PCIe generations such as gen 2. This is not supported on GPUs below GFX9, e.g. GFX8 cards in Fiji and Polaris families.
If you are using any PCIe switches in your system, please note that PCIe Atomics are only supported on some switches, such as Broadcom PLX. When you install your GPUs, make sure you install them in a fully PCIe Gen3 x16 or x8, x4 or x1 slot attached either directly to the CPU's Root I/O controller or via a PCIe switch directly attached to the CPU's Root I/O controller.
In our experience, many issues stem from trying to use consumer motherboards which provide physical x16 connectors that are electrically connected as e.g. PCIe Gen2 x4, PCIe slots connected via the Southbridge PCIe I/O controller, or PCIe slots connected through a PCIe switch that does not support PCIe atomics.
If you attempt to run ROCm on a system without proper PCIe atomic support, you may see an error in the kernel log (dmesg):
kfd: skipped device 1002:7300, PCI rejects atomics
Experimental support for our Hawaii (GFX7) GPUs (Radeon R9 290, R9 390, FirePro W9100, S9150, S9170) does not require or take advantage of PCIe Atomics. However, we still recommend that you use a CPU from the list provided above for compatibility purposes.
- ROCm 1.9 and Vega10 should support PCIe Gen2 enabled CPUs such as the AMD Opteron, Phenom, Phenom II, Athlon, Athlon X2, Athlon II and older Intel Xeon and Intel Core Architecture and Pentium CPUs. However, we have done very limited testing on these configurations, since our test farm has been catering to CPU listed above. This is where we need community support; if you find problems on such setups, please report these issues.
- Thunderbolt 1, 2, and 3 enabled breakout boxes should now be able to work with ROCm. Thunderbolt 1 and 2 are PCIe Gen2 based, and thus are only supported with GPUs that do not require PCIe Gen 3 atomics (i.e. Vega 10). However, we have done no testing on this configuration and would need comunity support due to limited access to this type of equipment
- "Tonga", "Iceland", "Polaris 12", and "Vega M" GPUs are not supported in ROCm 1.9.x
- We do not support GFX8-class GPUs (Fiji, Polaris, etc.) on CPUs that do not have PCIe Gen 3 with PCIe atomics.
- As such, do not support AMD Carrizo and Kaveri APUs as hosts for such GPUs..
- Thunderbolt 1 and 2 enabled GPUs are not supported by GFX8 GPUs on ROCm. Thunderbolt 1 & 2 are PCIe Gen2 based.
- AMD Carrizo based APUs have limited support due to OEM & ODM's choices when it comes to some key configuration parameters. In particular, we have observed that Carrizo laptops, AIOs, and desktop systems showed inconsistencies in exposing and enabling the System BIOS parameters required by the ROCm stack. Before purchasing a Carrizo system for ROCm, please verify that the BIOS provides an option for enabling IOMMUv2 and that the system BIOS properly exposes the correct CRAT table - please inquire with the OEM about the latter.
- AMD Merlin/Falcon Embedded System is not currently supported by the public repo.
- AMD Raven Ridge APU are currently not supported as GPU targets
- Dynamic Power Management feature is enabled on Vega 7nm.

Developer preview (alpha) of profiling tool rocProfiler. It includes a command-line front-end, rpl_run.sh, which enables:
- Cmd-line tool for dumping public per kernel perf-counters/metrics and kernel timestamps
- Input file with counters list and kernels selecting parameters
- Multiple counters groups and app runs supported
- Output results in CSV format
The tool can be installed from the rocprofiler-dev package. It will be installed into: /opt/rocm/bin/rpl_run.sh
The ROCr Debug Agent is a library that can be loaded by ROCm Platform Runtime to provide the following functionality:
- Print the state for wavefronts that report memory violation or upon executing a "s_trap 2" instruction.
- Allows SIGINT (
ctrl c) or SIGTERM (kill -15) to print wavefront state of aborted GPU dispatches. - It is enabled on Vega10 GPUs on ROCm1.9.
The ROCm1.9 release will install the ROCr Debug Agent library at /opt/rocm/lib/librocr_debug_agent64.so
- Binary package support for Ubuntu 18.04
Upstream Linux kernels support the following GPUs in these releases: 4.17: Fiji, Polaris 10, Polaris 11 4.18: Fiji, Polaris 10, Polaris 11, Vega10
Some ROCm features are not available in the upstream KFD:
- More system memory available to ROCm applications
- Interoperability between graphics and compute
- RDMA
- IPC
To try ROCm with an upstream kernel, install ROCm as normal, but do not install the rock-dkms package. Also add a udev rule to control /dev/kfd permissions:
echo 'SUBSYSTEM=="kfd", KERNEL=="kfd", TAG+="uaccess", GROUP="video"' | sudo tee /etc/udev/rules.d/70-kfd.rules

The packages in the Debian repository have been signed to ensure package integrity.
sudo apt update
sudo apt dist-upgrade
sudo apt install libnuma-dev
sudo rebootFor Debian based systems, like Ubuntu, configure the Debian ROCm repository as follows:
wget -qO - http://repo.radeon.com/rocm/apt/debian/rocm.gpg.key | sudo apt-key add -
echo 'deb [arch=amd64] http://repo.radeon.com/rocm/apt/debian/ xenial main' | sudo tee /etc/apt/sources.list.d/rocm.listThe gpg key might change, so it may need to be updated when installing a new release. If the key signature verification is failed while update, please re-add the key from ROCm apt repository. The current rocm.gpg.key is not avialable in a standard key ring distribution, but has the following sha1sum hash:
f7f8147431c75e505c58a6f3a3548510869357a6 rocm.gpg.key
Next, update the apt repository list and install the rocm package:
Warning: Before proceeding, make sure to completely uninstall any previous ROCm package:
sudo apt update
sudo apt install rocm-dkmsWith move to upstreaming the KFD driver and the support of DKMS, for all Console aka headless user, you will need to add all your users to the 'video" group by setting the Unix permissions
Configure Ensure that your user account is a member of the "video" group prior to using the ROCm driver. You can find which groups you are a member of with the following command:
groupsTo add yourself to the video group you will need the sudo password and can use the following command:
sudo usermod -a -G video $LOGNAME You may want to ensure that any future users you add to your system are put into the "video" group by default. To do that, you can run the following commands:
echo 'ADD_EXTRA_GROUPS=1' | sudo tee -a /etc/adduser.conf
echo 'EXTRA_GROUPS=video' | sudo tee -a /etc/adduser.confOnce complete, reboot your system.
Upon Reboot run the following commands to verify that the ROCm installation waas successful. If you see your GPUs listed by both of these commands, you should be ready to go!
/opt/rocm/bin/rocminfo
/opt/rocm/opencl/bin/x86_64/clinfo Note that, to make running ROCm programs easier, you may wish to put the ROCm libraries in your LD_LIBRARY_PATH environment variable and the ROCm binaries in your PATH.
echo 'export LD_LIBRARY_PATH=/opt/rocm/opencl/lib/x86_64:/opt/rocm/hsa/lib:$LD_LIBRARY_PATH' | sudo tee -a /etc/profile.d/rocm.sh
echo 'export PATH=$PATH:/opt/rocm/bin:/opt/rocm/profiler/bin:/opt/rocm/opencl/bin/x86_64' | sudo tee -a /etc/profile.d/rocm.shIf you have an Install Issue please read this FAQ .
Some users may want to install a subset of the full ROCm installation. In particular, if you are trying to install on a system with a limited amount of storage space, or which will only run a small collection of known applications, you may want to install only the packages that are required to run OpenCL applications. To do that, you can run the following installation command instead of the command to install rocm-dkms.
sudo apt-get install dkms rock-dkms rocm-openclBuild and run Hello World OCL app.
HelloWorld sample:
wget https://raw.githubusercontent.com/bgaster/opencl-book-samples/master/src/Chapter_2/HelloWorld/HelloWorld.cpp
wget https://raw.githubusercontent.com/bgaster/opencl-book-samples/master/src/Chapter_2/HelloWorld/HelloWorld.clBuild it using the default ROCm OpenCL include and library locations:
g++ -I /opt/rocm/opencl/include/ ./HelloWorld.cpp -o HelloWorld -L/opt/rocm/opencl/lib/x86_64 -lOpenCLRun it:
./HelloWorldTo un-install the entire rocm development package execute:
sudo apt autoremove rocm-dkmsIt is often useful to develop and test on different systems. In this scenario, you may prefer to avoid installing the ROCm Kernel to your development system.
In this case, install the development subset of packages:
sudo apt update
sudo apt install rocm-devNote: To execute ROCm enabled apps you will require a system with the full ROCm driver stack installed
It is recommended to remove previous rocm installations before installing the latest version to ensure a smooth installation.
If you installed any of the ROCm pre-release packages from github, they will need to be manually un-installed:
sudo apt purge hsakmt-roct
sudo apt purge hsakmt-roct-dev
sudo apt purge compute-firmware
sudo apt purge $(dpkg -l | grep 'kfd\|rocm' | grep linux | grep -v libc | awk '{print $2}')If possible, we would recommend starting with a fresh OS install.
Support for CentOS/RHEL 7 has been added in ROCm 1.8, but requires a special runtime environment provided by the RHEL Software Collections and additional dkms support packages to properly install in run.
RHEL is a subscription based operating system, and must enable several external repositories to enable installation of the devtoolset-7 environment and the DKMS support files. These steps are not required for CentOS.
First, the subscription for RHEL must be enabled and attached to a pool id. Please see Obtaining an RHEL image and license page for instructions on registering your system with the RHEL subscription server and attaching to a pool id.
Second, enable the following repositories:
sudo subscription-manager repos --enable rhel-server-rhscl-7-rpms
sudo subscription-manager repos --enable rhel-7-server-optional-rpms
sudo subscription-manager repos --enable rhel-7-server-extras-rpmsThird, enable additional repositories by downloading and installing the epel-release-latest-7 repository RPM:
sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmTo setup the Devtoolset-7 environment, follow the instructions on this page:
https://www.softwarecollections.org/en/scls/rhscl/devtoolset-7/
Note that devtoolset-7 is a Software Collections package, and is not supported by AMD.
Installing kernel drivers on CentOS/RHEL 7.4/7.5 requires dkms tool being installed:
sudo yum install -y epel-release
sudo yum install -y dkms kernel-headers-`uname -r` kernel-devel-`uname -r`It is recommended to remove previous rocm installations before installing the latest version to ensure a smooth installation.
At this point ROCm can be installed on the target system. Create a /etc/yum.repos.d/rocm.repo file with the following contents:
[ROCm]
name=ROCm
baseurl=http://repo.radeon.com/rocm/yum/rpm
enabled=1
gpgcheck=0The repo's URL should point to the location of the repositories repodata database. Install ROCm components using these commands:
sudo yum install rocm-dkmsThe rock-dkms component should be installed and the /dev/kfd device should be available on reboot.
Ensure that your user account is a member of the "video" or "wheel" group prior to using the ROCm driver. You can find which groups you are a member of with the following command:
groupsTo add yourself to the video (or wheel) group you will need the sudo password and can use the following command:
sudo usermod -a -G video $LOGNAME Current release supports CentOS/RHEL 7.4 and 7.5. If users want to update the OS version, they should completely remove ROCm packages before updating to the latest version of the OS, to avoid DKMS related issues.
Some users may want to install a subset of the full ROCm installation. In particular, if you are trying to install on a system with a limited amount of storage space, or which will only run a small collection of known applications, you may want to install only the packages that are required to run OpenCL applications. To do that, you can run the following installation command instead of the command to install rocm-dkms.
sudo yum install rock-dkms rocm-openclTo compile applications or samples, please use gcc-7.2 provided by the devtoolset-7 environment. To do this, compile all applications after running this command:
scl enable devtoolset-7 bashTo un-install the entire rocm development package execute:
sudo yum autoremove rocm-dkmsThe ROCm SMI library calls to rsmi_dev_power_cap_set() and rsmi_dev_power_profile_set() will not work for all but the first gpu in multi-gpu set ups.
The ROCm platform relies on a few closed source components to provide functionality such as HSA image support. These components are only available through the ROCm repositories, and will either be deprecated or become open source components in the future. These components are made available in the following packages:
- hsa-ext-rocr-dev
Modifications can be made to the ROCm 1.9 components by modifying the open source code base and rebuilding the components. Source code can be cloned from each of the GitHub repositories using git, or users can use the repo command and the ROCm 1.9 manifest file to download the entire ROCm 1.9 source code.
Google's repo tool allows you to manage multiple git repositories simultaneously. You can install it by executing the following commands:
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repoNote: make sure ~/bin exists and it is part of your PATH
mkdir ROCm && cd ROCm
repo init -u https://github.com/RadeonOpenCompute/ROCm.git -b roc-1.9.1
repo syncThese series of commands will pull all of the open source code associated with the ROCm 1.9.1 release. Please ensure that ssh-keys are configured for the target machine on GitHub for your GitHub ID.
- OpenCL Runtime and Compiler will be submitted to the Khronos Group, prior to the final release, for conformance testing.
