LTSI 3.4 is Now Available for Download

Nearly 2 years ago, the Linux Foundation’s Consumer Electronics (CE) working group created the Long Term Support Initiative (LTSI) Linux kernel for consumer electronics devices in order to have a common stable platform released every 2 years, and share the kernel development work among competing companies including Hitachi, LG Electronics, NEC, Panasonic, Qualcomm Atheros, Renesas Electronics Corporation, Samsung Electronics, Sony and Toshiba. Last week, the CE working group has released LTSI 3.4 kernel, based on Linux 3.4.25 kernel release and including several backported features from newer kernels including: The Contiguous Memory Allocator (CMA), which is extremely useful for embedded devices that have very limited hardware resources and will better handle the large memory requirements of multimedia applications. CMA originally was merged into the 3.4.0 kernel release, but its functionality was quite limited. Since then, the feature has been significantly improved in the kernel.org releases and those fixes have been added to […]

LTSI (Long-Term Stable Initiative) Status Update – ELCE 2012

Tsugikazu Shibata, chief manager of OSS promotion center at NEC, gives a status update for LTSI, an LTS kernel for the consumer electronics market at ELCE 2012. Abstract: LTSI (Long-Term Stable Initiative) had been established October 2011 as an activity of CE Working Group of The Linux Foundation. LTSI will maintain Linux kernel for long term and stable for use of Consumer Electronics industry to share common cost and also help industry engineers to merge their patches into upstream. This talk will update latest status of LTSI project and discuss about next step such as how the development process going on and what version of Linux kernel will be maintained for long term and stably use. This talk will be intended to provide information for managers and engineers in the embedded industry and not necessary to have specific knowledge. Agenda of the talk: Status of Linux kernel development and maintenance […]

Modular Graphics on Embedded ARM – ELCE 2012

Philipp Zabel, kernel developer at Pengutronix, discusses about graphics and video support for Linux on embedded SoCs at Embedded Linux Conference Europe 2012. Abstract: Porting Linux to new ARM based application processors has recently become easier than ever: the kernel gained many new frameworks like common-clock, oftree and pinmux. However, things get complicated when it comes to high end embedded graphics units.Those graphics systems tend to be composed of a multitude of on-SoC functional blocks that can operate on shared graphics buffers and video signals, as well as off-SoC encoder/converter chips that can be mixed and matched with any SoC.The old framebuffer is certainly not enough for today’s hardware any more, while modern frameworks like KMS and DRM have their own hassles on non-PC style graphics systems.The talk outlines issues we found while working on graphics and video support for the MX53 and MX6 CPUs and gives suggestions for possible […]

Olimex A13-OLinuXino-MICRO Development Board Unboxing And Review

Every Friday, Olimex organizes an online competition where they give away one of their board. They’ll ask a (usually simple) technical question on their twitter account at 22h00 (GMT+7), and all you have to do is to reply to their tweet with the correct answer within one hour. The winner is then selected randomly with random.org. There are usually 50 to 100 respondents so the odds are pretty good. I played a few times, and finally, I was lucky enough to win an A13-OLinuXino-MICRO development board at the beginning of December. I received it yesterday, after UPS took a whooping 15 days to deliver the board (Way to go UPS!). The board can be purchased on Olimex for 35 Euros plus shipping and taxes, or even lower if you order larger quantities. A13-OLinuXino-MICRO is a stripped down version of A13-OLinuXino-WIFI with the following specs: SoC – AllWinner A13 Cortex A8 […]

Linaro 12.12 Release with Linux Kernel 3.7 and Android 4.2.1

Linaro release 12.12 has just been announced, and includes Linux Kernel 3.7 and Android 4.2.1. The tracking version (stable release) uses Kernel 3.4.22. This release upgrades Android to version 4.2.1, Ubuntu images are now based on Ubuntu 12.10 (Quantal Quetzal) and Linaro U-Boot 2012.12 has been released with support for Origen 4 Quad and Arndale boards. Further improvements have been done for OpenEmbedded ARMv8, where they replaced the php Apache module by php-fpm among other things. On the kernel side, USB drivers have been refactored, and a kernel size analysis have been performed on several platforms. The power management team has mainly worked on big.LITTLE IKS and MP implementations, and it’s the first time LEG (Linaro Enterprise Group) is included in the release, and they worked on UEFI for ARM, GRUB for U-Boot, and provided a Ubuntu server image for Arndale board which can boot via UEFI or UBoot. Here […]

Linux 3.7 Release

Linus Torvalds has announced the release of Linux Kernel 3.7: Whee. After an extra rc release, 3.7 is now out. After a few more trials at fixing things, in the end we ended up reverting the kswapd changes that caused problems. And with the extra rc, I had decided to risk doing the buffer.c cleanups that would otherwise have just been marked for stable during the next merge window, and had enough time to fix a few problems that people found there too. There’s also a fix for a SCSI driver bug that was exposed by the last-minute workqueue fixes in rc8. Other than that, there’s a few networking fixes, and some trivial fixes for sparc and MIPS. Anyway, it’s been a somewhat drawn out release despite the 3.7 merge window having otherwise appeared pretty straightforward, and none of the rc’s were all that big either. But we’re done, and […]
