ARM Releases Kernel Drivers for Mali-T880 / T860 GPUs, User Space Drivers for Mali-T76x GPUs

ARM Mali GPU drivers includes both open source kernel drivers, and binary userspace drivers supporting framebuffer and/ior X11 implementation. The former is rarely an issue and is quickly released, but the latter requires porting and testing for a specific hardware platform, as well legal work, which greatly delay the releases. Mali-T880 GPU was announced at the beginning of the month together with ARM Cortex A72, and on February 17, 2015, ARM released an update to their Mali-T600 series, Mali-T700 series & Mali-T860/T880 GPU kernel device drivers with revision r5p1-00rel0 that adds supports to Mali-T860 and Mali-T880 GPU. These open source drivers are available for Android and Linux, and also support early Mali-T700 and T600 GPUs. Separately, the company has also released Mali-T76X GPU drivers for Firefly board powered by Rockchip RK3288 quad core Cortex A17 processor featuring a Mali-T764 GPU. The first release only supports the framebuffer driver, but ARM […]

Qualcomm Unveils Snapdragon 650 and 652 ARM Cortex A72 / A53 Processors

[Update: Title updated to reflect the new names of the processors. Snapdragon 618 is now Snapdragon 650, and 620 is now 652 to reflect the better Cortex A72 cores used in those processors] Qualcomm has announced four new processors including Snapdragon 415 and 425 octa-core Cortex A53 processor, as well a Snapdragon 618 and 620 big.LITTLE processor with the latest Cortex A72 cores coupled with four Cortex A53 little cores. Snapdragon 618 is the hexa-core version with 2 Cortex A72 cores, while Snapdragon 620 comes with eight cores including 4 Cortex A72, but apart from the difference in number of cores, both share the same technical specifications: CPU Snapdragon 618 – 64-bit dual-core ARM Cortex A72 @ 1.8GHz  and quad-core Cortex A53 @ 1.2GHz Snapdragon 620 – 64-bit quad-core ARM Cortex A72 @ 1.8GHz  and quad-core Cortex A53 @ 1.2GHz GPU – Next generation Qualcomm Adreno GPU with support for […]

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 […]

Online Labs pBox (C1 Node) is a mini ARM Server with 4 Gigabit Ethernet Ports, mSATA and mPCIe Slots

Online Labs, a subsidiary of Iliad (free), recently launched hosting services with dedicated ARM servers based on Marvell processor with modules they call C1. The company has decided to design a baseboard (pBox) for C1 module, and, as I understand it, plans to sell it to the public. It’s an exciting development for those who are looking for affordable and tiny purpose built Linux ARM servers. Preliminary C1 Node / pBox mini server specifications (based on C1 specs and bits of information gathered online): SoC – Marvell Armada 370/XP quad core ARMv7 processor @ up to 1.2 GHz System Memory – 2GB RAM Storage – 256 MB NAND flash + mSATA slot + eSATA port + micro SD slot Connectivity – 4x Gigabit Ethernet ports USB – 1x micro USB port Expansion – mini PCie, 1x 20-pin header for expansion (no details yet) Debugging – 20-pin JTAG connector Power Supply […]

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 […]
