Reprogrammable Hardware Support for Linux - Alan Tull, Altera

Sign up or log in to save this to your schedule and see who's attending!

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.

Alan Tull

Senior Software Engineer, Altera
Alan Tull has 14 years’ experience writing Linux drivers. He has written a kernel framework (on the mailing list) for controlling FPGA’s (Field Programmable Gate Arrays) including a manufacturer-agnostic set of functions for programming FPGA’s and a simple-fpga-bus that loads FPGA’s under the control of device tree overlays. His other recent work includes upstreamed driver support for Designware GPIOs, added regulator control for the... Read More →
