+
+## Enhanced Installation Process for ROCm v4.5
+
+In addition to the installation method using the native Package Manager, AMD ROCm v4.5 introduces added methods to install ROCm. With this
+release, the ROCm installation uses the *amdgpu-install* and *amdgpu-uninstall* scripts. 
+
+The *amdgpu-install* script streamlines the installation process by:
+
+-   Abstracting the distribution-specific package installation logic
+
+-   Performing the repository set-up
+
+-   Allowing user to specify the use case and automating the installation of all the required packages,
+
+-   Performing post-install checks to verify whether the installation was performed successfully
+
+-   Installing the uninstallation script
+
+The *amdgpu-uninstall* script allows the removal of the entire ROCm stack by using a single command.
+
+Some of the ROCm-specific use cases that the installer currently supports are:
+
+-   OpenCL (ROCr/KFD based) runtime
+
+-   HIP runtimes
+
+-   ROCm libraries and applications
+
+-   ROCm Compiler and device libraries
+
+-   ROCr runtime and thunk
+
+**Note:** Graphics use cases are not supported in this release.

+
+# What's New in This Release 
+
+## HIP Enhancements
+
+The ROCm v4.5 release consists of the following HIP enhancements:
+
+### HIP Direct Dispatch
+
+The conventional producer-consumer model where the host thread(producer) enqueues commands to a command queue (per stream), which is then
+processed by a separate, per-stream worker thread (consumer) created by the runtime, is no longer applicable.
+
+In this release, for Direct Dispatch, the runtime directly queues a packet to the AQL queue (user mode queue to GPU) in Dispatch and some of
+the synchronization. This new functionality indicates the total latency of the HIP Dispatch API and the latency to launch the first wave on the
+GPU.
+
+In addition, eliminating the threads in runtime has reduced the variance in the dispatch numbers as the thread scheduling delays and
+atomics/locks synchronization latencies are reduced.
+
+This feature can be disabled by setting the following environment variable,
+
+```     
+     AMD_DIRECT_DISPATCH=0
+
+```
+
+### Support for HIP Graph 
+
+ROCm v4.5 extends support for HIP Graph. For details, refer to the HIP
+API Guide at
+
+https://github.com/RadeonOpenCompute/ROCm/blob/master/AMD-HIP-API-4.5.pdf
+
+### Enhanced *launch_bounds* Check Error Log Message 
+
+When a kernel is launched with HIP APIs, for example, hipModuleLaunchKernel(), HIP validates to check that input kernel
+dimension size is not larger than specified launch_bounds.
+
+If exceeded, HIP returns launch failure if AMD_LOG_LEVEL is set with the proper value. Users can find more information in the error log message,
+including launch parameters of kernel dim size, launch bounds, and the name of the faulting kernel. It is helpful to figure out the faulting
+kernel. Besides, the kernel dim size and launch bounds values will also assist in debugging such failures.
+
+For more details, refer to the HIP Programming Guide at
+
+https://github.com/RadeonOpenCompute/ROCm/blob/master/AMD_HIP_Programming_Guide.pdf
+
+
+### HIP Runtime Compilation
+
+HIP now supports runtime compilation (hipRTC), the usage of which will provide the possibility of optimizations and performance improvement
+compared with other APIs via regular offline static compilation. 
+
+hipRTC APIs accept HIP source files in character string format as input parameters and create handles of programs by compiling the HIP source
+files without spawning separate processes.
+
+For more details on hipRTC APIs, refer to the HIP API Guide at
+
+https://github.com/RadeonOpenCompute/ROCm/blob/master/AMD-HIP-API-4.5.pdf
+
+### New Flag for Backwards Compatibility on float/double atomicAdd Function
+
+In the ROCm4.5 release, a new compilation flag is introduced as an
+option in the CMAKE file. This flag ensures backwards compatibility in
+float/double atomicAdd functions.
+
+```   
+     \_\_HIP_USE_CMPXCHG_FOR_FP_ATOMICS
+```   
+
+This compilation flag is not set("0") by default, so the HIP runtime uses the current float/double atomicAdd functions.
+
+If this compilation flag is set to "1" with the CMAKE option, the existing float/double atomicAdd functions is used for compatibility with
+compilers that do not support floating point atomics.
+
+```  
+     D\_\_HIP_USE_CMPXCHG_FOR_FP_ATOMICS=1
+```  
+For details on how to build the HIP runtime, refer to the HIP Programming Guide at
+
+https://github.com/RadeonOpenCompute/ROCm/blob/master/AMD_HIP_Programming_Guide.pdf
+
+
+
+### Updated HIP Version Definition
+
+The HIP version definition is updated as follows:
+
+```  
+     HIP_VERSION=HIP_VERSION_MAJOR \* 10000000 + HIP_VERSION_MINOR \*
+     100000 + HIP_VERSION_PATCH)
+```  
+
+The HIP version can be queried from the following HIP API call,
+
+```  
+     hipRuntimeGetVersion(&runtimeVersion);
+```  
+
+The version returned is always greater than the versions in the previous
+ROCm releases.
+
+**Note:** The version definition of the HIP runtime is different from that of CUDA. The function returns the HIP runtime version on the AMD
+platform, while on the NVIDIA platform, it returns the CUDA runtime version. There is no mapping or a correlation between the HIP and CUDA
+versions.
+
+
+
+### Planned HIP Enhancements and Fixes
+
+#### Changes to hiprtc implementation to match nvrtc behavior
+
+In this release, there are changes to the *hiprtc* implementation to
+match the *nvrtc* behavior.
+
+**Impact:** Applications can no longer explicitly include HIP runtime header files. Minor code changes are required to remove the HIP runtime
+header files.
+
+#### HIP device attribute enumeration
+
+In a future release, there will be a breaking change in the HIP device attribute enumeration. Enum values are being rearranged to accommodate
+future enhancements and additions.
+
+**Impact:** This will require users to rebuild their applications. No code changes are required.
+
+#### Changes to behavior of hipGetLastError() and hipPeekAtLastError() to match CUDA behavior available
+
+In a later release, changes to behavior of hipGetLastError() and hipPeekAtLastError() to match CUDA behavior will be available.
+
+**Impact:** Applications relying on the previous behavior will be impacted and may require some code changes.
+
+## Unified Memory Support in ROCm
+
+Unified memory allows applications to map and migrate data between CPU and GPU seamlessly without explicitly copying it between different
+allocations. This enables a more complete implementation of *hipMallocManaged*, *hipMemAdvise*, *hipMemPrefetchAsync* and related
+APIs. Without unified memory, these APIs only support system memory. With unified memory, the driver can automatically migrate such memory to
+GPU memory for faster access.
+
+### Supported Operating Systems and Versions
+
+This feature is only supported on recent Linux kernels. Currently, it works on Ubuntu versions with 5.6 or newer kernels and the DKMS driver
+from ROCm. Current releases of RHEL and SLES do not support this feature yet. Future releases of those distributions will add support for this.
+The unified memory feature is also supported in the KFD driver included with upstream kernels starting from Linux 5.14.
+
+Unified memory only works on GFXv9 and later GPUs, including Vega10 and MI100. Fiji, Polaris and older GPUs are not supported. To check whether
+unified memory is enabled, look in the kernel log for this message:
+
+```  
+     \$ dmesg \| grep \"HMM registered"
+```  
+
+If unified memory is enabled, there should be a message like "HMM registered xyzMB device memory". If unified memory is not supported on
+your GPU or kernel version, this message is missing.
+
+### Unified Memory Support and XNACK
+
+Unified memory support comes in two flavours, XNACK-enabled and XNACK-disabled. XNACK refers to the ability of the GPU to handle page
+faults gracefully and retry a memory access. In XNACK-enabled mode, the GPU can handle retry after page-faults, which enables mapping and
+migrating data on demand, as well as memory overcommitment. In XNACK-disabled mode, all memory must be resident and mapped in the GPU
+page tables when the GPU is executing application code. Any migrations involve temporary preemption of the GPU queues by the driver. Both page
+fault handling and preemptions, happen automatically and are transparent to the applications.
+
+XNACK-enabled mode only has experimental support. XNACK-enabled mode requires compiling shader code differently. By default, the ROCm
+compiler builds code that works in both modes. Code can be optimized for one specific mode with compiler options:
+
+OpenCL:
+
+```  
+     clang \... -mcpu=gfx908:***xnack+***:sramecc- \... // xnack on, sramecc off\
+     clang \... -mcpu=gfx908:***xnack-***:sramecc+ \... // xnack off, sramecc on
+```  
+
+HIP:
+```  
+     clang \... \--cuda-gpu-arch=gfx906:xnack+ \... // xnack on\
+     clang \... \--cuda-gpu-arch=gfx906:xnack- \... // xnack off
+```  
+Not all the math libraries included in ROCm support XNACK-enabled mode on current hardware. Applications will fail to run if their shaders are
+compiled in the incorrect mode.
+
+On current hardware, the XNACK mode can be chosen at boot-time by a module parameter amdgpu.noretry. The default is XNACK-disabled
+(amdgpu.noretry=1).
+
+## System Management Interface 
+
+### Enhanced ROCm SMI --setpoweroverdrive Functionality
+
+The ROCm System Management Interface (SMI) *--setpoweroverdrive* functionality is used to lower the power cap on a device without needing
+to enable the OverDrive functionality in the driver. Similarly, even with the OverDrive driver functionality enabled, it is possible to
+request a lower power cap than the card's default.
+
+Currently, any use of the *--setpoweroverdrive* functionality in rocm-smi prints an out-of-spec warning to the screen and requires the
+user to agree that using this functionality potentially voids their warranty. However, this warning should only be printed when users are
+trying to set the power cap to higher than the card's default, which requires the OverDrive driver functionality to be enabled.
+
+For example:
+
+The default power cap is 225.0W before any changes.
+
+```
+
+     \[atitest\@rhel85 smi\]\$ ./rocm_smi.py --resetpoweroverdrive
+     ======================= ROCm System Management Interface =======================
+
+     ========================== Reset GPU Power OverDrive ===========================
+
+     GPU\[0\] : Successfully reset Power OverDrive to: 225W
+     ============================ End of ROCm SMI Log ============================
+
+     Now, after using --setpoweroverdrive to lower the power cap to 123
+     watts:
+
+     \[atitest\@rhel85 smi\]\$ ./rocm_smi.py --setpoweroverdrive 123
+     ======================= ROCm System Management Interface =======================
+
+     =========================== Set GPU Power OverDrive ============================
+
+     GPU\[0\] : Successfully set power to: 123W
+     ======================= End of ROCm SMI Log ==============================
+
+     Setting a power cap lower than the default of 225.0W (in this case,
+     123W) does not give a warning.
+
+     To verify that the power is set to the correct value:
+
+     \[atitest\@rhel85 smi\]\$ ./rocm_smi.py --showmaxpower
+     ======================= ROCm System Management Interface =======================
+
+     ======================== Power Cap ===================================
+
+     GPU\[0\] : Max Graphics Package Power (W): 123.0
+     ========================End of ROCm SMI Log ==============================
+```
+
+
+## OpenMP Enhancements
+
+The ROCm installation includes an LLVM-based implementation, which fully
+supports OpenMP 4.5 standard and a subset of the OpenMP 5.0 standard.
+Fortran and C/C++ compilers and corresponding runtime libraries are
+included. Along with host APIs, the OpenMP compilers support offloading
+code and data onto GPU devices.

+
+# Known Issues in This Release 
+
+The following are the known issues in this release.
+
+## clinfo and rocminfo Do Not Display Marketing Name
+
+clinfo and rocminfo display a blank field for Marketing Name. 
+
+This is due to a missing package that is not yet available from ROCm. This package will be distributed in future ROCm releases.
+
+## Compiler Support for Function Pointers and Virtual Functions
+
+A known issue in the compiler support for function pointers and virtual functions on the GPU may cause undefined behavior due to register
+corruption. 
+
+A temporary workaround is to compile the affected application with this option:
+
+```
+     -mllvm -amdgpu-fixed-function-abi=1
+     
+ ```
+
+**Note:** This is an internal compiler flag and may be removed without notice once the issue is addressed in a future release.
+
+
+## Debugger Process Exit May Cause ROCgdb Internal Error
+
+If the debugger process exits during debugging, ROCgdb may report internal errors. This issue occurs as it attempts to access the AMD GPU
+state for the exited process. To recover, users must restart ROCgdb.
+ 
+As a workaround, users can set breakpoints to prevent the debugged process from exiting. For example, users can set breakpoints at the last
+statement of the main function and in the abort() and exit() functions. This temporary solution allows the application to be re-run without
+restarting ROCgdb.
+
+This issue is currently under investigation and will be fixed in a future release.
+
+For more information, refer to the ROCgdb User Guide at,
+
+https://github.com/RadeonOpenCompute/ROCm/blob/master/ROCDebugger_User_Guide.pdf
+
+## Cache Issues with ROCProfiler
+
+When the same kernel is launched back-to-back multiple times on a GPU, a cache flush is executed each time the kernel finishes when profiler data is collected. The cache flush is inserted by ROCprofiler for each kernel. This prevents kernel from being cached, instead it is being read each time it is launched. As a result the cache hit rate from rocprofiler is reported as 0% or very low.
+
+This issue is under investigation and will be fixed in a future release. 
+
+## Stability Issue on LAMMPS-KOKKOS Applications
+
+On mGPU machines, lammps-kokkos applications experience a stability issue (AMD Instinct MI100™). 
+
+As a workaround, perform a Translation LookAside Buffer (TLB) flush. 
+
+The issue is under active investigation and will be resolved in a future release.
+
+
+
+# Deprecations
+
+## AMD Instinct MI25 End of Life
+
+ROCm release v4.5 is the final release to support AMD Instinct MI25. AMD Instinct MI25 has reached End of Life (EOL). ROCm 4.5 represents the
+last certified release for software and driver support. AMD will continue to provide technical support and issue resolution for AMD
+Instinct MI25 on ROCm v4.5 for a period of 12 months from the software GA date. 
+
+## Planned Deprecation for Code Object Versions 2 and 3 
+
+With the ROCm v4.5 release, the generation of code object versions 2 and 3 is being deprecated and may be removed in a future release. This deprecation notice does not impact support for the execution of AMD GPU code object versions.
+
+The -mcode-object-version Clang option can be used to instruct the compiler to generate a specific AMD GPU code object version. In ROCm v4.5, the compiler can generate AMD GPU code object version 2, 3, and 4, with version 4 being the default if not specified. 
+
+
+
+# Deploying ROCm
+
+AMD hosts both Debian and RPM repositories for the ROCm packages. 
+
+For more information on ROCM installation on all platforms, see
+
+https://rocmdocs.amd.com/en/latest/Installation_Guide/Installation-Guide.html
+
+
+# Machine Learning and High Performance Computing Software Stack for AMD GPU
+
+For an updated version of the software stack for AMD GPU, see
+
+https://rocmdocs.amd.com/en/latest/Installation_Guide/Software-Stack-for-AMD-GPU.html
+
+
+
+# Hardware and Software Support
+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 supports a targeted set of hardware configurations which are detailed further in this section.
+
+**Note:** The AMD ROCm™ open software platform is a compute stack for headless system deployments. GUI-based software applications are currently not supported.
+
+#### Supported GPUs
+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.
+
+**Note:** The integrated GPUs of Ryzen are not officially supported targets for ROCm.
+
+ROCm officially supports AMD GPUs that use following chips:
+
+* GFX9 GPUs
+
+  - "Vega 10" chips, such as on the AMD Radeon RX Vega 64 and Radeon Instinct MI25
+  
+  - "Vega 7nm" chips, such as on the Radeon Instinct MI50, Radeon Instinct MI60 or AMD Radeon VII, Radeon Pro VII
+
+* CDNA GPUs
+
+  - MI100 chips such as on the AMD Instinct™ MI100
+
+
+ROCm is a collection of software ranging from drivers and runtimes 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 enabled in the ROCm software, though full support is not guaranteed:
+
+  * GFX8 GPUs
+    * "Polaris 11" chips, such as on the AMD Radeon RX 570 and Radeon Pro WX 4100
+    * "Polaris 12" chips, such as on the AMD Radeon RX 550 and Radeon RX 540
+  * GFX7 GPUs
+    * "Hawaii" chips, such as the AMD Radeon R9 390X and FirePro W9100
+
+As described in the next section, GFX8 GPUs require PCI Express 3.0 (PCIe 3.0) with support for PCIe atomics. This requires both CPU and motherboard support. GFX9 GPUs require PCIe 3.0 with support for PCIe atomics by default, but they can operate in most cases without this capability.
+
+The integrated GPUs in AMD APUs are not officially supported targets for ROCm.
+As described [below](#limited-support), "Carrizo", "Bristol Ridge", and "Raven Ridge" APUs are enabled in our upstream drivers and the ROCm OpenCL runtime.
+However, they are not enabled in the HIP runtime, and may not work due to motherboard or OEM hardware limitations.
+As such, they are not yet officially supported targets for ROCm.
+
+For a more detailed list of hardware support, please see [the following documentation](https://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units).
 
 #### Supported CPUs
-The ROCm Platform leverages PCIe Atomics (Fetch ADD, Compare and SWAP, 
-Unconditional SWAP, AtomicsOpCompletion).
-[PCIe atomics](https://github.com/RadeonOpenCompute/RadeonOpenCompute.github.io/blob/master/ROCmPCIeFeatures.md)
-are only supported on PCIe Gen3 Enabled CPUs and PCIe Gen3 Switches like
-Broadcom PLX. When you install your GPUs make sure you install them in a fully
-PCIe Gen3 x16 or x8 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. This typically occurs when connecting via the 
-Southbridge PCIe I/O controller. If you motherboard is part of this category,
-please do not use this connector for your GPUs, if you intend to exploit ROCm.
+As described above, GFX8 GPUs require PCIe 3.0 with PCIe atomics in order to run ROCm.
+In particular, the CPU and every active PCIe point between the CPU and GPU require support for PCIe 3.0 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:
 
-Our GFX8 GPU's (Fiji & Polaris Family) and GFX9 (Vega)  use PCIe Gen 3 and PCIe Atomics. 
+  * AMD Ryzen CPUs
+  * The CPUs in 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
 
-Current CPUs which support PCIe Gen3 + PCIe Atomics are: 
-  * 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).
-  * AMD Ryzen CPUs;
-  
-Upcoming CPUs which will support PCIe Gen3 + PCIe Atomics are:
-  * AMD Naples Server CPUs; 
-  * Cavium Thunder X Server Processor. 
+Beginning with ROCm 1.8, GFX9 GPUs (such as Vega 10) no longer require PCIe atomics.
+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 PCIe 2.0.
+This is not supported on GPUs below GFX9, e.g. GFX8 cards in the Fiji and Polaris families.
 
-Experimental support for our GFX7 GPUs Radeon R9 290, R9 390, AMD FirePro S9150, S9170 note they do not support or
-take advantage of PCIe Atomics. However, we still recommend that you use a CPU
-from the list provided above. 
+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 PCIe 3.1.0 x16, 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.
 
-#### Not supported or very limited support under ROCm 
-* We do not support ROCm with PCIe Gen 2 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.  
-* We also do not support AMD Carrizo and Kaveri APU as host for compliant dGPU
- attachments.
-* Thunderbolt 1 and 2 enabled GPU's are not supported by 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. On point, 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. If this is the case, the final requirement is
-associated with correct CRAT table support - please inquire with the OEM about 
-the latter.
-* AMD Merlin/Falcon Embedded System is also not currently supported by the public Repo. 
-* AMD Raven Ridge APU are currently not supported 
+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 2.0 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.
 
-### New Features to ROCm 1.7
-
-#### DKMS driver installation
-
- * New driver installation uses Dynamic Kernel Module Support (DKMS)
- * Only amdkfd and amdgpu kernel modules are installed to support AMD hardware
- * Currently only Debian packages are provided for DKMS (no Fedora suport available)
- * See the [ROCT-Thunk-Interface](https://github.com/RadeonOpenCompute/ROCT-Thunk-Interface/tree/roc-1.7.x) and [ROCK-Kernel-Driver](https://github.com/RadeonOpenCompute/ROCK-Kernel-Driver/tree/roc-1.7.x) for additional documentation on driver setup
-
-#### Developer preview of the new OpenCL 1.2 compatible language runtime and compiler
-
- * OpenCL 2.0 compatible kernel language support with OpenCL 1.2 compatible
-   runtime

-* [ROCm-Device-Libs](https://github.com/RadeonOpenCompute/ROCm-Device-Libs/tree/roc-1.7.x)
-
-#### Supported Operating Systems
-
-The ROCm 1.7 platform has been tested on the following operating systems:
- * Ubuntu 16.04
-
-### Installing from AMD ROCm repositories
-AMD is hosting only debian repositories for the ROCm 1.7 packages at this time. It is expected
-that an rpm repository will be available in the next point release.
-
-The packages in the Debian repository have been signed to ensure package integrity.
-Directions for each repository are given below:
-
-##### First make sure your system is up to date 
-
-```shell
-sudo apt update
-sudo apt dist-upgrade
-sudo apt install libnuma-dev
-sudo reboot
+If you attempt to run ROCm on a system without proper PCIe atomic support, you may see an error in the kernel log (`dmesg`):
 ```
-#### Optional: Upgrade to 4.13 kernel
-Although not required, it is recommended as of ROCm 1.7.1 that the system's kernel is upgraded to the latest 4.13 version available:
-
-```shell
-sudo apt install linux-headers-4.13.0-32-generic linux-image-4.13.0-32-generic linux-image-extra-4.13.0-32-generic linux-signed-image-4.13.0-32-generic
-sudo reboot 
-```
-#### Packaging server update
-The packaging server has been changed from the old http://packages.amd.com
-to the new repository site http://repo.radeon.com. 
-
-#### Debian repository - apt
-
-##### Add the ROCm apt repository
-For Debian based systems, like Ubuntu, configure the Debian ROCm repository as
-follows:
-
-```shell
-wget -qO - http://repo.radeon.com/rocm/apt/debian/rocm.gpg.key | sudo apt-key add -
-sudo sh -c 'echo deb [arch=amd64] http://repo.radeon.com/rocm/apt/debian/ xenial main > /etc/apt/sources.list.d/rocm.list'
-```
-The gpg key might change, so it may need to be updated when installing a new 
-release. The current rocm.gpg.key is not avialable in a standard key ring distribution,
-but has the following sha1sum hash:
-
-f0d739836a9094004b0a39058d046349aacc1178  rocm.gpg.key
-
-##### Install or Update
-Next, update the apt repository list and install/update the rocm package:
-
->**Warning**: Before proceeding, make sure to completely
->[uninstall any previous ROCm package](https://github.com/RadeonOpenCompute/ROCm#removing-pre-release-packages):
-
-```shell
-sudo apt update
-sudo apt install rocm-dkms
+kfd: skipped device 1002:7300, PCI rejects atomics
 ```
 
-###### Next set your permsions 
-With 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
+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.
 
-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:
+#### Not supported or limited support under ROCm
 
-```shell
-groups
-```
+##### Limited support
 
-To add yourself to the video group you will need the sudo password and can use the following command:
+* ROCm 4.x should support PCIe 2.0 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 CPUs 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 2.0 based, and thus are only supported with GPUs that do not require PCIe 3.1.0 atomics (e.g. Vega 10). However, we have done no testing on this configuration and would need community support due to limited access to this type of equipment.
+* AMD "Carrizo" and "Bristol Ridge" APUs are enabled to run OpenCL, but do not yet support HIP or our libraries built on top of these compilers and runtimes.
+  * As of ROCm 2.1, "Carrizo" and "Bristol Ridge" require the use of upstream kernel drivers.
+  * In addition, various "Carrizo" and "Bristol Ridge" platforms may not work due to OEM and ODM choices when it comes to key configurations parameters such as inclusion of the required CRAT tables and IOMMU configuration parameters in the system BIOS.
+  * Before purchasing such a 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. Inquire with your vendor about the latter.
+* AMD "Raven Ridge" APUs are enabled to run OpenCL, but do not yet support HIP or our libraries built on top of these compilers and runtimes.
+  * As of ROCm 2.1, "Raven Ridge" requires the use of upstream kernel drivers.
+  * In addition, various "Raven Ridge" platforms may not work due to OEM and ODM choices when it comes to key configurations parameters such as inclusion of the required CRAT tables and IOMMU configuration parameters in the system BIOS.
+  * Before purchasing such a 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. Inquire with your vendor about the latter.
 
-```shell
-sudo usermod -a -G video $LOGNAME 
-``` 
+##### Not supported
 
-Once complete, reboot your system.
+* "Tonga", "Iceland", "Vega M", and "Vega 12" GPUs are not supported.
+* We do not support GFX8-class GPUs (Fiji, Polaris, etc.) on CPUs that do not have PCIe 3.0 with PCIe atomics.
+  * As such, we 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 based on PCIe 2.0.
 
-We recommend you [verify your installation](https://github.com/RadeonOpenCompute/ROCm#verify-installation) to make sure everything completed successfully.
+In the default ROCm configuration, GFX8 and GFX9 GPUs require PCI Express 3.0 with PCIe atomics. The ROCm platform leverages these advanced capabilities to allow features such as user-level submission of work from the host to the GPU. This includes PCIe atomic Fetch and Add, Compare and Swap, Unconditional Swap, and AtomicOp Completion.
 
-#### To install ROCm with Developer Preview of OpenCL 
+#### ROCm support in upstream Linux kernels
 
-##### Start by following the instruction of installing ROCm with Debian repository:
+As of ROCm 1.9.0, the ROCm user-level software is compatible with the AMD drivers in certain upstream Linux kernels.
+As such, users have the option of either using the ROCK kernel driver that are part of AMD's ROCm repositories or using the upstream driver and only installing ROCm user-level utilities from AMD's ROCm repositories.
 
-No additional steps are required. The rocm-opencl package is now installed with rocm-dkms as a dependency. This includes the development package, rocm-opencl-dev.
- 
- 
-###### Upon restart, To test your OpenCL instance 
+These releases of the upstream Linux kernel support the following GPUs in ROCm:
+ * 4.17: Fiji, Polaris 10, Polaris 11
+ * 4.18: Fiji, Polaris 10, Polaris 11, Vega10
+ * 4.20: Fiji, Polaris 10, Polaris 11, Vega10, Vega 7nm
 
- Build and run Hello World OCL app..
+The upstream driver may be useful for running ROCm software on systems that are not compatible with the kernel driver available in AMD's repositories.
+For users that have the option of using either AMD's or the upstreamed driver, there are various tradeoffs to take into consideration:
 
-HelloWorld sample:

-##### Installing development packages for cross compilation
-It 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:
 
-```shell
-sudo apt update
-sudo apt install rocm-dev
-```

->**Note:** To execute ROCm enabled apps you will require a system with the full
->ROCm driver stack installed
 
-##### Removing pre-release packages
-If you installed any of the ROCm pre-release packages from github, they will
-need to be manually un-installed:
-
-```shell
-sudo apt purge libhsakmt
-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.
-
-#### RPM repository - dnf (yum)
-
-A repository containing rpm packages is currently not available for the ROCm 1.7 release.
-
-#### Closed source components
-The ROCm platform relies on a few closed source components to provide legacy
-functionality like HSAIL finalization and debugging/profiling 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
-
-### Getting ROCm source code
-Modifications can be made to the ROCm 1.7 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 1.7 manifest file to download the entire ROCm 1.7 source code.
-
-#### Installing repo
-Google's repo tool allows you to manage multiple git repositories
-simultaneously. You can install it by executing the following commands:
-
-```shell
-curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
-chmod a+x ~/bin/repo
-```
-Note: make sure ~/bin exists and it is part of your PATH
-
-#### Cloning the code
-```shell
-mkdir ROCm && cd ROCm
-repo init -u https://github.com/RadeonOpenCompute/ROCm.git -b roc-1.7.1
-repo sync
-```
-These series of commands will pull all of the open source code associated with
-the ROCm 1.7 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.
