Hello everybody, I work for Aeroflex Gaisler (formely Gaisler Research) which develops the LEON SPARC V8 processor. It is a synthesizable soft core CPU written in VHDL and used in a wide range of applications. We are currently maintaining our own Linux kernel and distribution for the processor but would like to contribute it into the mainline kernel. We understand that this will require some time and work in cooperation with the SPARC Linux community. Some technical background information about the LEON CPU: LEON3 is fully SPARC V8 compliant and has a standard SRMMU as well (except we support 4 to 32 kB pages). The cache system is VIVT with keys but can do snooping on the physical addresses. The cache is write through and configurable in regards to number of sets, way size and replacement algorithm. It has a AMBA AHB/APB bus system and supports SMP. There is a rich set of peripherals that can be added to your typical SoC system such as 10/100/1G Ethernet MAC, USB host controller (EHCI/UHCI), USB device controller, PCI, ATA, SPI, CAN, etc. We have received an account on kernel.org and will maintain a sparc-leon git repository there. I guess sparc-next is the proper repository to clone as a base for our patches? Is there any special way that you would like us to structure our code to fit into the current SPARC tree as painlessly as possible? Currently our kernel sources can be downloaded here: ftp://gaisler.com/gaisler.com/linux/linux-2.6/linux/linux-2.6.21.1-leon23-1.0.3.tar.bz2 Internally we are however at version 2.6.29 and will be setting up an up to date git repository for you to scrutinize.
