Blackfin architecture

2.6.22 adds support for yet another architecture: The Analog Devices Blackfin processor architecture, and currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561 (Dual Core) devices, with a variety of development platforms including those avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP, BF561-EZKIT), and Bluetechnix! Tinyboards.

The Blackfin architecture was jointly developed by Intel and Analog Devices Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in December of 2000. Since then ADI has put this core into its Blackfin processor family of devices. The Blackfin core has the advantages of a clean, orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC (Multiply/Accumulate), state-of-the-art signal processing engine and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture.

The Blackfin architecture, including the instruction set, is described by the [http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf ADSP-BF53x/BF56x Blackfin Processor Programming Reference]. The Blackfin processor is already supported by major releases of gcc, and [http://blackfin.uclinux.org/gf/project/toolchain/frs there are available binary and source rpms/tarballs for many architectures]. There is [http://docs.blackfin.uclinux.org/ complete documentation, including "getting started" guides], which provides links to the sources and patches you will need in order to set up a cross-compiling environment for bfin-linux-uclib. All the code is actively supported by Analog Devices Inc, at: http://blackfin.uclinux.org

VMI (Virtual Machine Interface)

New drivers

Crashing soon a kernel near you

This is a list of some of the ongoing patches being developed at the kernel community that will be part of future Linux releases. Those features may take many months to get into the Linus' git tree, or may be dropped. The features are tested in the -mm tree, but be warned, it can crash your machine, eat your data (unlikely but not impossible) or kidnap your family (just because it has never happened it doesn't mean you're safe):

Input

MTD

USB

V4L/DVB

Added VIDIOC_INT_G_STD_OUTPUT and VIDIOC_INT_S_STD_OUTPUT to allow drivers to set the TV standard for video output separately from the video capture. This is needed for cx23415 support where the decoder is separate from the encoder and can have a different TV standard. Modified the saa7127 module to listen to VIDIOC_INT_G/S_STD_OUTPUT instead of VIDIOC_G/S_STD.
