Linux 4.8 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has officially released Linux 4.8 last Sunday: So the last week was really quiet, which maybe means that I could probably just have skipped rc8 after all. Oh well, no real harm done. This obviously means that the merge window for 4.9 is open, and I appreciate the people who already sent in some pull requests early due to upcoming travel or other reasons. I’ll start pulling things tomorrow, and have even the most eager developers and testers hopefully test the final 4.8 release before the next development kernels start coming 😉 Anyway, there’s a few stragging fixes since rc8 listed below: it’s a mixture of arch fixes (arm, mips, sparc, x86), drivers (networking, nvdimm, gpu) and generic code (some core networking, with a few filesystem, cgroup and and vm things). All of it pretty small, and there really aren’t that many of them. Go forth and test, […]

Linux 4.7 Release – Main Changes, ARM and MIPS Architectures

Linux 4.7 is out: So, after a slight delay due to my travels, I’m back, and 4.7 is out. Despite it being two weeks since rc7, the final patch wasn’t all that big, and much of it is trivial one- and few-liners. There’s a couple of network drivers that got a bit more loving. Appended is the shortlog since rc7 for people who care: it’s fairly spread out, with networking and some intel Kabylake GPU fixes being the most noticeable ones. But there’s random small noise spread all over. And obviously, this means that the merge window for 4.8 is open.Judging by the linux-next contents, that’s going to be a bigger release than the current one (4.7 really was fairly calm, I blame at least partly summer in the northern hemisphere). Linus Linux 4.6 brought USB 3.1 superspeed, OrangeFS distributed file system, 802.1AE MAC-level encryption (MACsec), and BATMAN V protocol support, improved […]

Ingenic T10 is a MIPS Based Video Processor for 720p Cameras

Ingenic has been designing MIPS based SoCs using their Xburst processor engine for several years, which are found in tablets, development boards, and wearables. The company has now launched T10 smart video processor based on the same MIPS32 processor but mobile camera, security survey, video talking, video analysis and so on with image resolution up to 1280×960 (datasheet says 1280×1024), and videos up to 720p30 or VGA @ 30fps. Ingenic T10 specifications: CPU – XBurst single core MIPS32 processor up to 1GHz with FPU, 32KB L1 I-cache, 32KB L1 D-cache, and 128KB L2 unified cache. Memory – Embedded DDRII@400Mhz up to 512Mbit Encoder engine -H.264 baseline, main profile; MJPEG/JPEG Baseline Encode Performance Max resolution 1280×960 Up to H.264 960p@40fps encode H.264 multiple streams 720p@30fps + VGA@30fps + JPEG@15fps 960p@30fps + VGA@30fps + JPEG@15fps ABR/VBR/CBR/CQP 8 ROIs (Regions of Interest) 5-layer OSD with hardware ISP AE, AWB (automatic white balance), AF […]

Imagination Solution to FCC Rules for WiFi Routers: Run OpenWrt / DD-WRT and the WiFi Driver in Separate Virtual Machines

About a year ago, discussions started about new rules from the FCC that could prevent routers from installing open source third party operating systems such as OpenWrt or DDWRT. Despite the FCC assurance that the rules were meant to prevent some users from illegally tweaking the RF settings, and that it would not have to impact installing of open source alternatives, the reality is that companies such as TP-Link ended up locking their routers up due to the new rules, while Linksys would only ensure OpenWrt/ DD-WRT compatibility on some of their routers, but not all. Companies are probably doing that due to the extra work that would be required to separate the RF settings which need to be locked, and the rest of the firmware. But Imagination Technology’s prpl security group has a solution for their MIPS Warrior P-Class processors using hardware virtualization. In order to show the concept […]

Linux 4.6 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.6 earlier today: It’s just as well I didn’t cut the rc cycle short, since the last week ended up getting a few more fixes than expected, but nothing in there feels all that odd or out of line. So 4.6 is out there at the normal schedule, and that obviously also means that I’ll start doing merge window pull requests for 4.7 starting tomorrow. Since rc7, there’s been small noise all over, with driver fixes being the bulk of it, but there is minor noise all over (perf tooling, networking, filesystems,  documentation, some small arch fixes..) The appended shortlog will give you a feel for what’s been going on during the last week. The 4.6 kernel on the whole was a fairly big release – more commits than we’ve had in a while. But it all felt fairly calm despite that. Linux 4.5 added […]

Imagination Releases OpenWrt and LWM2M Stack Source Code for MIPS Creator Ci40 Development Board

MIPS Creator Ci40 is a development board made by Imagination technology that features the company’s Creator cXT200 “Pistachio” SoC with a dual core MIPS interAptiv processor @ 550MHz and Ensigma C4500 RPU for 802.11ac/ BT 4.1 LE connectivity. The boards are supposed to be shipped to Kickstarter backers in April, but in the meantime, the company has released the source code for OpenWrt distribution as well as LWM2M stack for the board. OpenWRT source code is available in OpenWrt repo in FlowM2M gitbub account. Building the code for MIPS Creator Ci40 is quite straightforward:

Select IMG MIPS Pistachio in make menuconfig, save the settings, and then run make to build OpenWrt for the board. This will also build the toolchain, so you don’t need to install any before hand. LWM2M stands for Lightweight Machine to Machine, and is a protocol from the Open Mobile Alliance (OMA) for M2M / […]

Linux 4.5 Released – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.5 on Sunday: So this is later on a Sunday than my usual schedule, because I just couldn’t make up my mind whether I should do another rc8 or not, and kept just waffling about it. In the end, I obviously decided not to,but it could have gone either way. We did have one nasty regression that got fixed yesterday, and the networking pull early in the week was larger than I would have wished for. But the block  layer should be all good now, and David went through all his networking commits an extra time just to make me feel comfy about it, so in the end I didn’t see any point to making the release cycle any longer than usual. And on the whole, everything here is pretty small. The diffstat looks a bit larger for an xfs fix, because that fix has […]

Tavolga Terminal TP-T22BT Debian 8 All-in-One Computer is Powered by Baikal-T1 MIPS Processor

A Russian company called Baikal Electronics announced it was working on Baikal T1 dual core MIPS P5600 to provide an alternative to US based Intel and AMD processor last year, not too long after Edwards Snowden revaluations about the NSA malpractices. Good progress has been made as T-Platforms has now launched Tavolga Terminal TP-T22BT All-in-One computer with a 21.5″ display, up to 8 GB RAM, and the Baikal T1 processor running Debian 8. TP-T22BT specifications (derived from product brief in Russian): Processor – Baikal dual core MIPS 5600 processor @ 1.0 GHz with 1MB L2 cache GPU – Silicon Motion SM750 GPU with 16MB video memory, 2D graphics acceleration System Memory – 2 to 8GB DDR3 Storage – Optional 8GB NAND flash, optional 8GB SSD, and optional 2.5″ SATA drive (Baikal-T1 has a built-in SATA interface) Display – 21.5″ IPS Full HD (1920×1080) display with LED backlight Audio – PCM2912A […]
