-## Are You Ready to ROCK!
-The ROCm Platform delivers on the vision of the  Boltzmann Initiative, bringing
-new opportunities in GPU Computing Research.
+## Are You Ready to ROCK?
+The ROCm Platform brings a rich foundation to advanced computing by seamlessly
+ integrating the CPU and GPU with the goal of solving real-world problems.
 
-On November 16th, 2015, the Radeon Technology Group rolled out Boltzmann
-Initiative with three core foundation elements:
+#### 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.
 
-* New Linux(R) Driver and Runtime Stack optimized for HPC & Ultra-scale class
-  computing,
-* Heterogeneous C and C++ compiler which best address the whole system not just
-  a single device
-* HIP acknowledging the need for platform choice when utilizing GPU computing
-  API
 
-Using our knowledge of the HSA Standards and, more importantly, the HSA 1.1
-Runtime we have been able to successfully extended support to the dGPU with
-critical features for NUMA class acceleration. As a result, the ROCK driver is
-composed of several components based on our efforts to develop the
-Heterogeneous System Architecture for APUs, including the new AMDGPU driver,
-the Kernel Fusion Driver (KFD), the HSA+ Runtime and an LLVM based compilation
-stack for the building of key language support. This support starts with AMD’s
-FIJI Family of dGPU, but support is planned to expand to include future ASICS.
+Our GFX8 GPU's (Fiji & Polaris Family) and GFX9 (Vega)  use PCIe Gen 3 and PCIe Atomics. 
 
-### The Latest ROCm Platform - ROCm 1.1
+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. 
+
+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. 
+
+#### 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 
+
+### 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 
+ * 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

-#### Debian repository - apt-get
+### 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
+```
+#### Optional: Upgrade to 4.13 kernel
+Although not required, it is recommended as of ROCm 1.7.2 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://packages.amd.com/rocm/apt/debian/rocm.gpg.key | sudo apt-key add -
-sudo sh -c 'echo deb [arch=amd64] http://packages.amd.com/rocm/apt/debian/ trusty main > /etc/apt/sources.list.d/rocm.list'
+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

 ```shell
-sudo vi /etc/default/grub
-sudo update-grub
+groups
 ```
 
+To add yourself to the video group you will need the sudo password and can use the following command:
+
+```shell
+sudo usermod -a -G video $LOGNAME 
+``` 
+
 Once complete, reboot your system.
 
 We recommend you [verify your installation](https://github.com/RadeonOpenCompute/ROCm#verify-installation) to make sure everything completed successfully.
 
+#### To install ROCm with Developer Preview of OpenCL 
+
+##### Start by following the instruction of installing ROCm with Debian repository:
+
+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 
+
+ Build and run Hello World OCL app..

+##### Known Issues / Workarounds
+
+######## If you Plan to Run with X11 - we are seeing  X freezes under load
+
+ROCm 1.7.2 a kernel parameter noretry has been set to 1 to improve overall system performance. However it has been proven to bring instability to graphics driver shipped with Ubuntu. This is an ongoing issue and we are looking into it.
+
+Before that, please try apply this change by changing noretry bit to 0.
+
+```shell
+echo 0 | sudo tee /sys/module/amdkfd/parameters/noretry
+```
+
+Files under /sys won't be preserved after reboot so you'll need to do it every time.
+
+One way to keep noretry=0 is to change /etc/modprobe.d/amdkfd.conf and make it be:
+
+options amdkfd noretry=0
+
+Once it's done, run sudo update-initramfs -u. Reboot and verify /sys/module/amdkfd/parameters/noretry stays as 0.
+
+
 ##### 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-get purge libhsakmt
-sudo apt-get purge radeon-firmware
-sudo apt-get purge $(dpkg -l | grep 'kfd\|rocm' | grep linux | grep -v libc | awk '{print $2}')
+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 dnf (yum) repostiory is also available for installation of rpm packages. To configure a
-system to use the ROCm rpm directory create the file /etc/yum.repos.d/rocm.repo with
-the following contents:
