Linux Kernel 3.10 Released

Linus Torvalds has announced the release of Linux Kernel 3.10: So I delayed this by a day, considering whether to do another -rc, but decided that there wasn’t enough upside. Sure, it hasn’t been as quiet as I’d like, and we had this long discussion about an inode list locking scalability issue over the last week or two, but in the end that issue turned out to not be new, and while we may end up back-porting the eventual resolution to 3.10, it wasn’t a reason to delay the release. Similarly, while I might wish for fewer pull requests during the late rc’s (and particularly the ones that came in Friday evening -inconvenient for a weekend release), at some point delaying things doesn’t really help things, and just makes the pent up demand for the next merge window worse. In other words, I could really have gone either way, but […]

Imagination Technologies Unveils MIPS “Warrior” 32 and 64 Bit CPU Cores

Last year, MIPS announced Aptiv Cores, but since then, the company has been bought by Imagination Technologies, and they’ve recently announced updates to the family, as well as new MIPS Series5 ‘Warrior’ CPU cores during Imagination Summit in Asia. Before I write about the update to Aptiv cores, let me remind you of the 3 Aptiv families: proAptiv – High performance cores (3.5DMIPS/Mhz) to be used in SoC for smartphone, tablets, …. 1 to 6 cores. Roughly equivalent to ARM Cortex A15. interAptiv – Medium performance core (1.7DMIPS/MHz) for mainstream STB, digital cameras, mid-range smartphones. 1 to 4 cores. Equivalent to ARM Cortex A5 microAptiv – Low power MCU and MPU cores Imagination has added a small-footprint single-core version to the interAptiv family without the extra logic associated with multi-core coherency and L2 cache controller, as well as a floating point version to the microAptiv family for applications such as […]

MIPS Releases Android 4.1.1 (Jelly Bean) Source Code

At the end of last month, MIPS announced the $125 Karbonn Mobiles Android Jelly Bean Tablet powered by Ingzenic MIPS-Based JZ4770 SoC. Today, they released Android 4.1.1 source code for MIPS Before downloading the Android source code, make sure you have a properly setup Linux workstation. Here are the instructions to checkout MIPS Android 4.1.1:

mkdir mipsandroid
cd mipsandroid
repo init -u  git://github.com/MIPS/manifests.git -b dev-mips-jb -m mips-jb-4.1.1_r1.xml
repo sync

mkdir mipsandroid

cd mipsandroid

repo init -u git://github.com/MIPS/manifests.git -b dev-mips-jb -m mips-jb-4.1.1_r1.xml

repo sync

You can read the release notes for more details about the current status of the MIPS Android Jelly Bean port. Myriad Dalvik turbo, an alternative Dalvik implement that is much faster than the default Dalvik engine (at least on MIPS), is not yet available for Android 4.1, but should be soon. All MIPS Android source code can also be viewed online at http://www.github.com/mips.
