Linux 4.10 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has just released Linux 4.10: So there it is, the final 4.10 release. It’s been quiet since rc8, but we did end up fixing several small issues, so the extra week was all good. On the whole, 4.10 didn’t end up as small as it initially looked. After the huge release that was 4.9, I expected things to be pretty quiet, but it ended up very much a fairly average release by modern kernel standards. So we have about 13,000 commits (not counting merges – that would be another 1200+ commits if you count those). The work is all over, obviously – the shortlog below is just the changes in the last week, since rc8. Go out and verify that it’s all good, and I’ll obviously start pulling stuff for 4.11 on Monday. Linus Linux 4.9 added Greybus staging support, improved security thanks to virtually mapped kernel stacks, […]

Baikal T1 BFK 1.6 MIPS Development Board Tested with OpenWrt

Baikal Electronics is a Russian fabless semiconductor company specializing in ARM and MIPS-based SoC, and we’ve already covered their Baikal T1 MIPS SoC announcement, as well as Tavolga Terminal TP-T22BT Debian 8 All-in-One Computer based on the processor. The company also have Baikal T1 BFK 1.6 development board, which does not appear to be publicly available yet, but one member of Habrahabr.ru forums got hold of one sample, and tested the OpenWrt SDK in Debian 8 host computer. First, we’ll have a look at the hardware they received. I don’t have the full specs of the board, but we’ll learn a little more below, in the meantime we can see two USB ports, Gigabit Ethernet ports, a 10GbE SFP cage, an mPCIe slot (I think), and two DB9 connector, as well as a bunch of other headers and connectors with SATA, GPIO, UART, I2C, SPI… I’ve then downloaded Baikal T1 BSP […]

Linux 4.9 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux 4.9 on Sunday: So Linux 4.9 is out, and the merge window for 4.10 is thus open. With the extra week for 4.9, the timing for the merge window is obviously a bit awkward, and it technically closes in two weeks on Christmas Day. But that is a pure technicality, because I will certainly stop pulling on the 23rd at the latest, and if I get roped into Xmas food prep, even that date might be questionable. I could extend the merge window rather than cut it short, but I’m not going to. I suspect we all want a nice calm winter break, so if your stuff isn’t ready to be merged early, the solution is to just not merge it yet at all, and wait for 4.11. Just so you all know (I already bcc’d the main merge window suspects in a separate mailing last […]

8Devices Rambutan Qualcomm Atheros QCA9557 / QCA9550 GbE & WiFi Modules and Development Kit Run OpenWrt

8Devices, a Lithuanian company specialized in the development and manufacturing of electronic equipment, is known for their Carambola and Carambola2 WiFi modules powered by Ralink and Qualcomm Atheros WiSoCs. The company has now introduced a new dual band WiFi module called Rambutan that comes in commercial and industrial temperature range through respectively Qualcomm Atheros QCA9557 & QCA9550 SoCs. Rambutan and Rambutan-I modules specifications: SoC Rambutan – Qualcomm Atheros QCA9557 MIPS processor @ 720 MHz Rambutan-I – Qualcomm Atheros QCA9550 MIPS processor @ 720 MHz System Memory – 128 MB DDR2 Storage – 128 MB Flash Connectivity WiFi – 802.11 a/b/g/n, 2.4 or 5 GHz, 2×2 MIMO, 300 Mbps data rate, 21 dB per chain output power; 2x u.FL connectors Ethernet – Atheros AR8032 10/100M Ethernet PHY 68x half holes with 2 x USB 2.0 host port 2 x serial port 1x 100 Base-T Ethernet port;  1000 Base-T Ethernet port  (SGMII […]

Vocore2 Lite is a $4 Linux MIPS WiFi Module based on Mediatek MT7688AN SoC (Crowdfunding)

I’ve already written about Vocore v2 Crowdfunding campaign, where the second generation Vocore WiFi module supports audio, PoE, and ultimate dock, and price starting at $12. But there has been some development since the launch of the campaign, as the developer received request for a cheaper board, and after looking into it, has now added Vocore2 Lite WiFi module reward for only $4, or $7 once shipping included. He obviously had to make some trade-offs to bring the cost down, but the Lite board impressively still keep many of the same features. VoCore (2014) VoCore2 Lite (2016) VoCore2 (2016) Price 19.99 USD 3.99 USD 11.99 USD CPU RT5350, 360MHz MT7688AN MIPS24KEc @ 580MHz MT7628AN, 580MHz Memory 32MB SDRAM 64MB DDR2 128MB DDR2 Storage 16MB NOR 8MB NOR 16MB NOR Antenna Slot x1 x1 x2 On-Board ANTENNA √ × √ Wireless Speed ~75Mbps ~150Mbps ~300Mbps Ethernet Port x5 x1 / x5 […]

Imagination Technologies Announces MIPS Warrior I-class I6500 Heterogeneous CPU with up to 384 Cores

Imagination has just unveiled the successor of MIPS I6400 64-Bit Warrior Core with MIPS Warrior I-class I6500 heterogeneous CPU supporting up to 64 cluster, with up to 6 cores each (384 cores max), themselves up to 4 thread (1536 max), combining with IOCU (IO coherence units), and external IP such as PowerVR GPU or other hardware accelerators. The main features of MIPS I6400 processor are listed as follows:   Heterogeneous Inside – In a single cluster, designers can optimize power consumption with the ability to configure each CPU with different combinations of threads, different cache sizes, different frequencies, and even different voltage levels. Heterogeneous Outside – The latest MIPS Coherence Manager with an AMBA ACE interface to popular ACE coherent fabric solutions such as those from Arteris and Netspeed lets designers mix on a chip configurations of processing clusters – including PowerVR GPUs or other accelerators – for high system […]

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 […]
