@@ -17,6 +17,22 @@ stack for the building of key language support. This support starts with AMD’s
FIJI Family of dGPU, and has expanded to include the Hawaii dGPU Family in ROCm 1.2
ROCm 1.3 expands this support to include the Polaris Family of ASICS.
#### Supported CPU's
* Our GFX8 GPU's ( FIJI & Polaris Familiy) use PCIe Gen 3 and PCIe Atomics (Fetch ADD,Compare and SWAP, Unconditional SWAP, AtomicsOpCompletion) To find out more about [PCIe atomics](https://github.com/RadeonOpenCompute/RadeonOpenCompute.github.io/blob/master/ROCmPCIeFeatures.md)
Current CPU which support PCIe Gen3 + PCIe Atomics are:
* Intel Xeon E5 v3 or newer CPU's
* Intel Xeon E3 v3 or newer CPU's
* Intel Core i7 v3, Core i5 v3, Core i3 v3 or newer CPU's
* AMD Ryzen CPU's
* AMD Naples Server CPU
* Cavium Thunder X Server Processor
* Our GF7 GPU's Radeon R9 290, R9 390, AMD FirePro S9150, S9170 do not support PCIe Atomics, but we do not recomend nor test ROCm with PCIe Gen 2 enabled CPU's such as the AMD Opeteron, Phenom, Phenom II, , Athlon, Athlon X2, Athlon II and Older Intel Xeon and Intel Core Archtecture CPU's.
AMD Carizzo based APU have limited support due to OEM & ODM's Carizzo enabled Laptop, All In One System and Desktop system had inconsistancy in supporting the correct System BIOS configurations for ROCm driver enablement. Before you buy a Carizzo system to run ROCm. Your should check the SBIOS to see if has an option to enable IOMMUv2. If this is enable next we need test for the correct CRAT Table to properly configure the driver.
I know many of you are looking forward to support support ROCm on APU system which support Fine Grained Shared Virtual Memory and cache coherency between the CPU and GPU. In the 2017 we plan on testing commercial AM4 Socketed Bristol Ridge and Raven Ridge motherboard. Just like we still waiting to get access to them, once we get our first board we blog about the experiance and begin building up a list of motherboard that are qualified with ROCm
### New Features to ROCm
#### Developer preview of the new OpenCl 1.2 compatible language runtime and compiler
