Linux 3.3 Released
diegocg writes "Linux 3.3 has been released. The changes include the merge of kernel code from the Android project. There is also support for a new architecture (TI C6X), much improved balancing and the ability to restripe between different RAID profiles in Btrfs, and several network improvements: a virtual switch implementation (Open vSwitch) designed for virtualization scenarios, a faster and more scalable alternative to the 'bonding' driver, a configurable limit to the transmission queue of the network devices to fight bufferbloat, a network priority control group and per-cgroup TCP buffer limits. There are also many small features and new drivers and fixes. Here's the full changelog."
Wow, I had no idea there was work in porting Linux to DSP architectures. That's quite an interesting development. I wonder what the use case is, since DSPs are typically used for very specific, real-time work, not for hosting general-purpose operating systems.
Also, it's quite surprising to me since as far as I know it's necessary to use TI's compiler to generate C6X code. I found one initiative to port GCC to it, but afaik it didn't get finished. My understanding is that it is no small job to get Linux to compile on non-supported compilers, so I'm interested in the toolchain they are using. For my own work on a C6711, I've been using the TI compiler under Wine. (Which works fine actually, although I had to generate an initial project in CodeComposer to get some of the board-specific support files.)
