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 […]

Linux 3.18 Released

Linus Torvalds released Linux Kernel 3.18 last Sunday: It’s been a quiet week, and the patch from rc7 is tiny, so 3.18 is out. I’d love to say that we’ve figured out the problem that plagues 3.17 for a couple of people, but we haven’t. At the same time, there’s absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn’t make sense. Especially since that would just have then held things up entirely over the holiday break. So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that “Ahaa” moment) over the next week. But in solidarity with Dave (and to make my life easier too 😉 let’s try to avoid introducing any _new_ […]

MIPS Creator CI20 Development Board is Now Available for $65

When Imagination Technologies first announced their developer program for MIPS Creator CI20 board, they did not disclose the price, but based on the specifications I estimated that a decent price would be $70 o $80. The company has now announced broad availability of the board, which can be pre-ordered for just $65 or 50 GBP depending on the continent you live in, with shipping scheduled for the end of January 2015. This development board is based on Ingenic JZ4780 dual core MIPS processor with 1GB DDR3, 8GB flash,  and features an HDMI output up to 1080p, Audio in and out, a Fast Ethernet RJ45 port, a Wireless module with Bluetooth 4.0 and Wi-Fi, an IR receiver, and expansion headers. Several projects have already been ported by developers who got their free board a few months, ago including XBMC/Kodi, several games such as Spiral Episode 1, and beside Android 4.4 and […]

Ingenic Unveils Newton2 Platform for Wearables with M200 Dual Core SoC

Ingenic Newton is a development platform for wearables powered by Ingenic JZ4775, an application processor mostly used in tablets. Many companies are now making SoCs speficially designed for wearables with a powerful application core, and a low power core serving as a sensor hub, an Ingenic M200 SoC found in the new Ingenic Newton2 platform, uses the sample principle by combinging a MIPS XBurst processor @ 1.2GHz with a low power MIPS XBurst core @ 300MHz combined with low power GPU and VPU. Ingenic Newton2 specifications: SoC – Ingenic M200 dual core processor with MIPS XBurst @ 1.2 GHz, MIPS XBurst @ 300 MHz, 2D/3D GPU, and VPU supporting H.264, VP8, MPEG-1/2/4, VC-1, and RV9 up to 720p30 System Memory – 512 MB LPPDR2 (Samsung eMCP) Storage – 4GB eMMC (Samsung eMCP) Connectivity – 802.11 b/g/n Wi-Fi + Bluetooth 4.1 (Broadcom BCM43438) + connector for GPS Sensors – Gyroscope, accelerometer, magnetometer […]

PowerVR SDK v3.4 Supports WebGL, 64-Bit Android 5.0 Lollipop, and MIPS Linux

Imagination Technolgies has just released PowerVR SDK v3.4  including the latest compilers for PowerVR Series6 and Series6XT GPUs to PVRShaderEditor, several performance optimization, a new WebGL SDK, 64-bit support for Android 5.0 Lollipop, and Linux support for MIPS based processors. The company has revamped the user interfaces of their tools, and made the following key changes: PVRTrace, a tool to capture and analyze OpenGL ES and EGL API calls, now supports OpenGL ES 3.1, compressed trace files, and they’ve reduce the software memory usage PVRTune, a performance analysis tool, now features new counters, and  “significant” performance optimizations. PVRShaderEditor, a light-weight shader editing too, adds the latest compilers for PowerVR Series6 (FP32 and FP16) and Series6XT GPUs, as well as GLSL disassembler output. PVRTexTool, a utility for compressing textures, adds plugin support for Autodesk 3DSMax and Maya (2015 versions), and improves ETC decompression by up to 20% faster per surface. Imagination also […]

Linux 3.17 Released

Linus Torvalds announced the release of Linux Kernel 3.17 on Sunday: So the past week was fairly calm, and so I have no qualms about releasing 3.17 on the normal schedule (as opposed to the optimistic “maybe I can release it one week early” schedule that was not to be). However, I now have travel coming up – something I hoped to avoid when I was hoping for releasing early. Which means that while 3.17 is out, I’m not going to be merging stuff very actively next week, and the week after that is LinuxCon EU… What that means is that depending on how you want to see it, the 3.18 merge window will either be three weeks, or alternatively just have a rather slow start. I don’t mind getting pull requests starting now (in fact, I have a couple already pending in my inbox), but I likely won’t start processing […]

Imagination Technologies Unveils MIPS I6400 64-Bit Warrior Core

Imagination technologies has just announced their MIPS I6400 64-bit core for applications including embedded, mobile, digital consumer, advanced communications, networking and storage. MIPS I-class I6400 CPU family features a 64-bit architecture, hardware virtualization, multi-threading, multi-core and multi-cluster coherent processing, and MIPS32 code will run on MIPS64. The key features of these MIPS64 cores are listed as follows: Efficient, scalable 64-bit performance – The company claims MIPS I6400 achieves over 50% higher CoreMark performance and 30% higher DMIPS compared to “leading competitors in its class”. Hardware multi-threading – Supports up to four hardware threads per core, and  simultaneous multi-threading (SMT) technology leads to higher utilization and CPU efficiency. Preliminary benchmarking shows that adding a second thread leads to performance increases of 40-50% on benchmarks such as SPECint and EEMBC’s CoreMark, with less than a 10% cluster area increase. Hardware virtualization – Includes support for up to 15 secure/non-secure guests. Next-generation security […]
