-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.
+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.

-At this time, the integrated GPUs in AMD APUs are not officially supported targets for ROCm.
+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 our HCC or HIP runtimes, and may not work due to motherboard or OEM hardware limitations.
+As such, they are not yet officially supported targets for ROCm.

- * RHEL 7.4. &. 7.5  (Using devetoolset-7 runtime support)

 ### Installing from AMD ROCm repositories

-AMD is hosting both Debian and RPM repositories for the ROCm 1.9.x packages at this time.
+AMD hosts both [Debian](http://repo.radeon.com/rocm/apt/debian/) and [RPM](http://repo.radeon.com/rocm/yum/rpm/) repositories for the ROCm 2.8.x packages at this time.

 The packages in the Debian repository have been signed to ensure package integrity.

+#### ROCm Binary Package Structure
+
+ROCm is a collection of software ranging from drivers and runtimes to libraries and developer tools.
+In AMD's package distributions, these software projects are provided as a separate packages.
+This allows users to install only the packages they need, if they do not wish to install all of ROCm.
+These packages will install most of the ROCm software into `/opt/rocm/` by default.
+
+The packages for each of the major ROCm components are:
+
+* ROCm Core Components
+  - ROCk Kernel Driver: `rock-dkms`
+  - ROCr Runtime: `hsa-rocr-dev`, `hsa-ext-rocr-dev`
+  - ROCt Thunk Interface: `hsakmt-roct`, `hsakmt-roct-dev`
+* ROCm Support Software
+  - ROCm SMI: `rocm-smi`
+  - ROCm cmake: `rocm-cmake`
+  - rocminfo: `rocminfo`
+  - ROCm Bandwidth Test: `rocm_bandwidth_test`
+* ROCm Development Tools
+  - HCC compiler: `hcc`
+  - HIP: `hip_base`, `hip_doc`, `hip_hcc`, `hip_samples`
+  - ROCm Device Libraries: `rocm-device-libs`
+  - ROCm OpenCL: `rocm-opencl`, `rocm-opencl-devel` (on RHEL/CentOS), `rocm-opencl-dev` (on Ubuntu)
+  - ROCM Clang-OCL Kernel Compiler: `rocm-clang-ocl`
+  - Asynchronous Task and Memory Interface (ATMI): `atmi`
+  - ROCr Debug Agent: `rocr_debug_agent`
+  - ROCm Code Object Manager: `comgr`
+  - ROC Profiler: `rocprofiler-dev`
+  - ROC Tracer: `roctracer-dev`
+  - Radeon Compute Profiler: `rocm-profiler`
+* ROCm Libraries
+  - rocALUTION: `rocalution`
+  - rocBLAS: `rocblas`
+  - hipBLAS: `hipblas`
+  - hipCUB: `hipCUB`
+  - rocFFT: `rocfft`
+  - rocRAND: `rocrand`
+  - rocSPARSE: `rocsparse`
+  - hipSPARSE: `hipsparse`
+  - ROCm SMI Lib: `rocm_smi_lib64`
+  - rocThrust: `rocThrust`
+  - MIOpen: `MIOpen-HIP` (for the HIP version), `MIOpen-OpenCL` (for the OpenCL version)
+  - MIOpenGEMM: `miopengemm`
+  - MIVisionX: `mivisionx`
+  - RCCL: `rccl`
+
+To make it easier to install ROCm, the AMD binary repositories provide a number of meta-packages that will automatically install multiple other packages.
+For example, `rocm-dkms` is the primary meta-package that is used to install most of the base technology needed for ROCm to operate.
+It will install the `rock-dkms` kernel driver, and another meta-package (`rocm-dev`) which installs most of the user-land ROCm core components, support software, and development tools.
+
+The `rocm-utils` meta-package will install useful utilities that, while not required for ROCm to operate, may still be beneficial to have.
+Finally, the `rocm-libs` meta-package will install some (but not all) of the libraries that are part of ROCm.
+
+The chain of software installed by these meta-packages is illustrated below
+
+```
+  rocm-dkms
+    |--rock-dkms
+    \--rocm-dev
+       |--hsa-rocr-dev
+       |--hsa-ext-rocr-dev
+       |--hsakmt-roct
+       |--hsakmt-roct-dev
+       |--rocm-cmake
+       |--rocm-device-libs
+       |--hcc
+       |--hip_base
+       |--hip_doc
+       |--hip_hcc
+       |--hip_samples
+       |--rocm-smi
+       |--hsa-amd-aqlprofile
+       |--comgr
+       |--rocr_debug_agent
+       \--rocm-utils
+          |--rocminfo
+          \--rocm-clang-ocl # This will cause OpenCL to be installed
+
+  rocm-libs
+    |--rocalution
+    |--hipblas
+    |--rocblas
+    |--rocfft
+    |--rocrand
+    |--hipsparse
+    \--rocsparse
+```
+
+These meta-packages are not required but may be useful to make it easier to install ROCm on most systems.
+Some users may want to skip certain packages. For instance, a user that wants to use the upstream kernel drivers (rather than those supplied by AMD) may want to skip the `rocm-dkms` and `rock-dkms` packages, and instead directly install `rocm-dev`.
+
+Similarly, a user that only wants to install OpenCL support instead of HCC and HIP may want to skip the `rocm-dkms` and `rocm-dev` packages.
+Instead, they could directly install `rock-dkms`, `rocm-opencl`, and `rocm-opencl-dev` and their dependencies.

+You may want to ensure that you have ssh-keys configured on your machine for your GitHub ID.
+
+#### Building the ROCm source code
+
+Each ROCm component repository contains directions for building that component.
+As such, you should go to the repository you are interested in building to find how to build it.
+
+That said, AMD also offers [a project](https://github.com/RadeonOpenCompute/Experimental_ROC) that demonstrates how to download, build, package, and install ROCm software on various distributions.
+The scripts here may be useful for anyone looking to build ROCm components.
+
+#### Deprecation Notice
+
+### HCC
+AMD is deprecating HCC to put more focus on HIP development and on
+other languages supporting heterogeneous compute.  We will no longer
+develop any new feature in HCC. We will stop maintaining HCC after
+its final release, which is planned for the end of 2019.  If your
+application was developed with the hc C++ API, we would encourage you
+to transition it to other languages supported by AMD, such as HIP or
+OpenCL.  HIP and hc languages share the same compiler technology, so
+many hc kernel language features (including inline assembly) are also
+available through the HIP compilation path.
+
+### hipThrust
+hip-thrust has been removed in ROCm2.7.
+
+
+### Final notes
+* OpenCL Runtime and Compiler will be submitted to the Khronos Group for conformance testing prior to its final release.

+#### MIOpen 2.0
+- This release contains several new features including an immediate mode for selecting convolutions, bfloat16 support, new layers, modes, and algorithms.
+- MIOpenDriver, a tool for benchmarking and developing kernels is now shipped with MIOpen.
+BFloat16 now supported in HIP requires an updated rocBLAS as a GEMM backend.
+- Immediate mode API now provides the ability to quickly obtain a convolution kernel.
+- MIOpen now contains HIP source kernels and implements the ImplicitGEMM kernels. This is a new feature and is currently disabled by default. Use the environmental variable "MIOPEN_DEBUG_CONV_IMPLICIT_GEMM=1" to activation this feature. ImplicitGEMM requires an up to date HIP version of at least 1.5.9211.
+- A new "loss" catagory of layers has been added, of which, CTC loss is the first. See the API reference for more details.
+2.0 is the last release of active support for gfx803 architectures. In future releases, MIOpen will not actively debug and develop new features specifically for gfx803.
+- System Find-Db in memory cache is disabled by default. Please see build instructions to enable this feature.

+* 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`
+
+
+#### New distribution support
+
+* Binary package support for Ubuntu 18.04
+
+#### ROCm 1.9 is ABI compatible with KFD in upstream Linux kernels.
+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
+```
+
+### New features as of ROCm 1.8.3
+
+* ROCm 1.8.3 is a minor update meant to fix compatibility issues on Ubuntu releases running kernel 4.15.0-33
+
+### New features as of ROCm 1.8
+
+#### DKMS driver installation
+
+ * Debian packages are provided for DKMS on Ubuntu
+ * RPM packages are provided for CentOS/RHEL 7.4 and 7.5 support
+ * See the [ROCT-Thunk-Interface](https://github.com/RadeonOpenCompute/ROCT-Thunk-Interface/tree/roc-1.8.x) and [ROCK-Kernel-Driver](https://github.com/RadeonOpenCompute/ROCK-Kernel-Driver/tree/roc-1.8.x) for additional documentation on driver setup
+
+#### New distribution support
+
+ * Binary package support for Ubuntu 16.04 and 18.04
+ * Binary package support for CentOS 7.4 and 7.5
+ * Binary package support for RHEL 7.4 and 7.5
+
+#### Improved OpenMPI via UCX support
+
+ * UCX support for OpenMPI
+ * ROCm RDMA
+
+### New Features as of 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
+
+### New Features as of ROCm 1.5
+
+#### 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
+ * Supports offline ahead of time compilation today;
+   during the Beta phase we will add in-process/in-memory compilation.
+
+#### Binary Package support for Ubuntu 16.04
+
+#### Binary Package support for Fedora 24 is not currently available
+
+#### Dropping binary package support for Ubuntu 14.04, Fedora 23
+
+#### IPC support

Joseph Greathouse	bd790cb4d2	README and repo overhaul for the ROCm 2.0 release Community feedback has pointed out a number of confusing, oudated, or missing sections in our ROCm README file. For example, we do not describe what our ROCm package structure is, or how the packages and meta-packages fit together. This can make it confusing for users who do not want to just install rocm-dkms and move on. Our repo manifest (default.xml) is severely out of date. It is missing almost all of the current ROCm projects, and it always pulls from the main development branch. This means we do not have a pinned manifest that allows you to pull the code from a particular ROCm reelease. Manifest updated, and the section of the README discussing it is majorly overhauled (including links for information/scripts about building the code after downloading it). Rather than continually grow our version history in the main README page, this splits off old version information into its own file.	2018-12-21 09:26:31 -06:00
