LCE-EU 2015

Field Programmable Gate Arrays (FPGA’s) are being integrated with SoC’s and processors, presenting new uses of the FPGA’s, like search engine acceleration, networking devices, etc. Proper Linux kernel support is required in a way that is consistent with the Linux kernel driver model and device trees. Thanks to the use of Device Tree Overlays, the dynamic nature of the FPGA’s can now be managed in the Linux kernel including reconfiguration of the hardware running on the FPGA, updating the device tree at run-time, handling drivers, etc. This talk presents the work being done at Altera Corporation to propose a new FPGA manager framework, its architecture and the status of upstreaming of its code and the collaboration with the community.
