Linux 3.19 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 3.19 yesterday: So nothing all that exciting happened, and while I was tempted a couple of times to do an rc8, there really wasn’t any reason for it. Just as an example, Sasha Levin used KASan and found an interesting bug in paravirtualized spinlocks, but realistically it’s been around forever, and it’s not even clear that it can really ever trigger in practice. We’ll get it fixed, and mark it for stable, and tempting as it was, it wasn’t really a reason to delay 3.19. And the actual fixes that went in (see appended shortlog) were all fairly small, with the exception of some medium-sized infiniband changes that were all reverting code that just wasn’t ready. So it’s out there – go and get it. And as a result, the merge window for 3.20 is obviously also now open. Linus Linux 3.18 improved performance of […]

Embedded Linux Conference 2015 Schedule – IoT, Cars, and Drones

Embedded Linux Conference 2015 will take place in San Jose, California, on March 23 – 25, 2015, and will focus on Drones, Things and Automobiles. The schedule has been published, and whether you’ll attend or not, it’s always interested to have a look at what will be talked about to have a peak into the future of Embedded Linux, or simply keep abreast with the progress in the field. So as usual, I’ve gone through the schedule, and made my own virtual program with talks that I find interesting. Monday 23rd 9:00 – 9:30 – Driving standards and Open Source to Grow the Internet of Things by Mark Skarpness, Director of Systems Engineering at Intel Billions of devices are beginning to come online, and many of these devices, large and small, are running open source software. To fuel this innovation, it’s more important than ever for these devices to use […]

Linaro 15.01 Release with Linux 3.19 and Android 5.0

Linaro has just announced the first release of the year with Linux 3.19-rc3 (baseline), Linux 3.10.65 and 3.14.29 (LSK), Android 5.0.2, and Ubuntu Linaro Utopic. Changes seem to have focused on ARM, Qualcomm, and HiSilicon hardware platforms such as Juno, and IFC6410, and some work has been done on Debian ARM64 rootfs. Here are the highlights of this release: Linux Linaro 3.19-rc5-2015.01 GATOR topic updated to version 5.20.1 builddeb topic: fixes for the dtb files location changes in 3.19 (vendor subdir introduced) updated integration-linaro-vexpress64 topic by ARM LT (FVP Base and Foundation models, and Juno support) updated topic from Qualcomm LT (IFC6410 board support) updated topic from HiSilicon LT (Hi36xx, HiP04, and X5HD2 families support) updated LLVM topic (uses the community llvmlinux-latest branch) Included ILP32 patch set v3 rebased on 3.19-rc5. Initial tests using syscalls LTP tests are done: msgctl07 stalls when using ILP32 userland (no stall with LP64 userland). […]

FOSDEM 2015 Schedule – January 31 – February 1 2015

FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks, divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]

AllWinner A64 is a $5 Quad Core 64-bit ARM Cortex A53 SoC for Tablets

Allwinner already announced H64 octa-core Cortex A53 processor for OTT boxes together with Nobel64 development board in the last quarter of last year, and the Chinese silicon manufacturer has now introduced Allwinner A64 quad core Cortex A53 processor for entry-level tablets, as the processor will only cost $5 per unit in large quantities. As usual, Allwinner only provided a subset of information for their first announcement, and some technical details like the GPU are unknown. Key features listed for Allwinner A64: 64-bit Cortex-A53 architecture Supports H.265/H.264 video decoding in hardware, and supports HDMI 4K display Supports various DDR memory types, making the BOM cost more competitive Supports eMMC 5.0 for better IO performance and enhanced data throughput capacity Allwinner SmartColor display technology for more vivid and eye-pleasing visual experience Supports Trusted Firmware security architecture from ARM The company is finally moving to a device tree enabled kernel with Linux 3.10, and Allwinner 64-bit ARM tablets will also run Android 5.0 Lollipop. Hopefully, this processor implements proper H.265 hardware decoding, not GPU accelerated decoding as in Allwinner A80 processor. Interestingly neither Allwinner A64, nor Rockchip RK3368 announced recently, support VP9, despite it being the codec of […]
