Linux 3.16 Released

Linus Torvalds announced the release of Linux Kernel 3.16 over the week-end: So nothing particularly exciting happened this week, and 3.16 is out there. And as usual (previous release being the exception) that means that the merge window for 3.17 is obviously open. And for the third time in a row, the timing sucks for me, as I have travel coming up the second week of the merge window. Many other core developers will be traveling too, since it’s just before the kernel summit in Chicago. So we’ll see how the next merge window goes, but I’m not going to worry about it overmuch. If I end up not having time to do all the merges, I might delay things into the week of the kernel summit, but I’ll hope to get most of the big merging done this upcoming week before any travel takes place, so maybe it won’t come […]

Amlogic GPL Source Code Release – Kernel 3.10, U-Boot, and Drivers (Wi-Fi, NAND, TVIN, Mali GPU)

Last month, I noticed Amlogic provided links to the Android SDK for S802 / M802 on their open source website, but the only way to get the source was to share your SSH public with Amlogic, so that they give you access. It did not happen, but the company has released the source for Linux 3.10.10, U-boot 2011.03, Realtek and Broadcom Wi-Fi drivers, NAND drivers, “TVIN”drivers, and kernel space GPU drivers for Mali-400 / 450 GPU. There are also some customer board files for Meson 6 only (AML8726-MX / M6) but they do not seem to match the kernel… If you want to build the kernel, including the drivers, you’ll need to download a bunch of files: wget http://openlinux.amlogic.com:8000/download/ARM/kernel/arm-src-kernel-2014-03-06-d5d0557b2b.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/rtk8192du-2014-03-06-7f70d95d29.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/rtk8192eu-2014-03-06-9766866350.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/rtk8192cu-2014-03-06-54bde7d73d.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/rtk8188eu-2014-03-06-2462231f02.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/brcmap6xxx-2014-03-06-302aca1a31.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/wifi-fw-2014-03-06-d3b2263640.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/modules/aml_tvin-2014-03-06-fb3ba6b1c8.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/modules/aml_nand-2014-03-06-39095c4296.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/customer/aml_customer-2014-03-06-76ce689191.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/gpu/gpu-2014-03-06-0425a1f681.tar.gz You’ll need to extract these tarballs in specific directories:

Intel Bay Trail Graphics Overview – FOSDEM 2014

Bay Trail SoCs are new low power Intel ICs for tablets (Bay Trail-T, Z3000 series), mobiles (Bay Trail-M, N2800, N2900 and N3500 series), desktops (Bay Trail-D, J1800, J1900 and J2900 series) and embedded / industrial platforms (Bay Trail-I, E3800 series). Many Atom processors used to features PowerVR GPU, but it has now been replaced by Intel HD graphics in Bay Trail SoC. Jesse Barnes, working at Intel on software and drivers for Intel graphics devices, gives a presentation about Bay Trail SoCs with a focus on graphics. After an overview, and some ARM bashing regarding performance (Nvidia Tegra 4 and Qualcomm Snapdragon 800), and even power consumption (Tegra 4 only), he describe further details about Intel HD graphics found in the new Intel processors. Everything is basically in mainline, and you’ll need Linux 3.10 or greater, Mesa 9.2 or greater, and libva 1.2.1 or greater for proper support. Some initial […]

Posted on by Jean-Luc Aufranc (CNXSoft) - 4 Comments on Cute Embedded Nonsense Hacks, Nouveau Driver for Tegra K1, and Android Defaults to ART

Cute Embedded Nonsense Hacks, Nouveau Driver for Tegra K1, and Android Defaults to ART

There’s been some news at the end of this week that may not warrant a full article, but are still fun and/or interesting nonetheless: comments by the lead developer of Fedora ARM  led to “Cute Embedded Nonsense” meme on Google+, preliminary commit for open source drivers for Tegra K1’s GPU, and Android Open Source Project defaults to ART instead of Dalvik. If you have a Google+ account, and circled a few people involved in ARM Linux, you must have seen a few postings about “Cute Embedded Nonsense Hacks” in your feed. It all started when Jon Masters posted about Red Hat’s ARM SBSA platform requirements, and in particular one comment that reads: I am all for people installing their own kernels if they want to. I support aggressively defined standard platforms (not cute embedded nonsense hacks) but not locked platforms. You can keep both parts when it breaks, of course. […]

GCW Zero Handheld Console Runs 3D Games via Open Source Vivante GPU Drivers (Etnaviv)

GCW Zero is an open source handheld gaming console featuring Ingenic JZ4770 MIPS processor with Vivante GC860 GPU, 512MB RAM, 16GB internal storage, and a 3.5″ LCD with 320×240 pixels. The device runs Linux (OpenDingux) , and retro games and emulators. GCW Zero had a successful kickstarter campaign, and is now available in a few shops such as ThinkGeek (US), DragonBox (EU) for $150 / 125 Euros. Today, I’m writing about this console, not because of amazing specs, nor price, but because it could be the first  device with an embedded SoC that retails with an open source GPU driver. In September of this year, GCW Zero received a firmware update with Etnaviv GPU driver for Vivante GC860 adding support for 3D games via OpenGL ES support. The video below shows Quake 3 Arena running on the game console with the Etnaviv drivers. Lots of OpenGL ES1 and 2 features […]

Linux 3.9 Release

Linus Torvalds has announced the release of Linux Kernel 3.9: So the last week was much quieter than the preceding ones, which makes me suspect that one reason -rc7 was bigger than I liked was that people were gaming the system and had timed some of their pull requests for just before the release, explaining why -rc7 was big enough that I didn’t  actually want to do a final release last week. Please don’t do that. Anyway. Whatever the reason, this week has been very quiet, which makes me much more comfortable doing the final 3.9 release, so I guess the last -rc8 ended up working. Because not only aren’t there very many commits here, even the ones that made it really are tiny and not pretty obscure and not very interesting. Also, this obviously means that the merge window is open. I won’t be merging anything today, but if […]

Ubuntu Linaro 12.11 with 2D/3D Mali-400 GPU Acceleration on ODROID-X Development Board

A few days ago, Hardkernel released the first version of Ubuntu 12.11 (Linaro) with Mali-400 GPU support for their ODROID boards (ODROID-X/X2, ODROID-U/U2). This is still WIP (Work in Progress), but this is one of the few boards together with Pandaboard, Origen and Snowball that can support 2D/3D GPU acceleration in Ubuntu Quantal. Since I have an ODROID-X development board, I decided to give it a try. There are different ways to install it. I chose the way that is most convenient for me (LCD display instead of HDMI), and likely to yield more performance (eMMC instead of SD Card). The current installation instructions to eMMC are extremely cumbersome and you have to go through 5 main steps: Install Android (yes, seriously) in the eMMC Install Ubuntu in the SD Card Install Ubuntu to the eMMC Upgrade Ubuntu to the latest version Install the Mali drivers In this post I’m […]

A Selection of FOSDEM 2013 Events

FOSDEM is a 2-day (or 3 if you include Friday beer event) event where over 5,000 members of open source communities meet, share ideas and collaborate. It’s free to attend, and there’s no registration, so you just show up to attend. FOSDEM 2013 takes place on Feb 2-3 (yep, this week-end) in Brussels There are 7 main tracks where sessions are organized: Operating systems Open source challenges Security Janson Beyond operating systems Web development Miscellaneous Robotics There are also keynotes and devroom for a total of 488 sessions. Developers rooms that may particularly be of interest to readers of this blog are: Cross Desktop devroom – e.g. Wayland, gstreamer, razor-qt, Qt Project, Plasma Active, etc… Cross Distro devroom – e.g. Linux on Android, suse on ARM, ARMv8, systemd, etc… Embedded and mobile devroom – e.g. Baserock Embedded Linux, Guacamayo (Yocto), Nemo Mobile/ Mer project, arduino… All in all that’s a […]
