Linux 4.19 Release – Main Changes, Arm and MIPS Architectures

Linux 4.19 Changelog

With Linus Torvalds taking a leave from the Linux kernel project, Greg Kroah-Hartman was the one to release Linux 4.19 last Sunday: Hi everyone! It’s been a long strange journey for this kernel release… While it was not the largest kernel release every by number of commits, it was larger than the last 3 releases, which is a non-trivial thing to do. After the original -rc1 bumps, things settled down on the code side and it looks like stuff came nicely together to make a solid kernel for everyone to use for a while. And given that this is going to be one of the “Long Term” kernels I end up maintaining for a few years, that’s good news for everyone. A small trickle of good bugfixes came in this week, showing that waiting an extra week was a wise choice. However odds are that linux-next is just bursting so the next -rc1 merge window is going to be bigger …

Linux 4.18 Release – Main Changes, Arm and MIPS Architecture

Linux Changelog 4.18

Linus Torvalds has just announced the release of Linux 4.18: One week late(r) and here we are – 4.18 is out there. It was a very calm week, and arguably I could just have released on schedule last week, but we did have some minor updates. Mostly networking, but some vfs race fixes (mentioned in the rc8 announment as “pending”) and a couple of driver fixes (scsi, networking, i2c). Some other minor random things (arm crypto fix, parisc memory ordering fix). Shortlog appended for the (few) details. Some of these I was almost ready to just delay to until the next merge window, but they were marked for stable anyway, so it would just have caused more backporting. The vfs fixes are for old races that  are really hard to hit (which is obviously why they are old and weren’t noticed earlier). Some of them _have_ been seen in real life, some of them probably need explicit help to ever …

Banana Pi BPI-R64 Router Board is Powered by Mediatek MT7622, Supports 802.11ac WiFi, Optional PoE Module

Banana Pi BPI-R64

SinoVoIP launched several Banana Pi router boards in the past starting with Allwinner A20 based Banana Pi BPI-R1 in 2014, and followed by Banana Pi BPI-R2 board powered by a Mediatek MT7623 processor last year. Such boards normally include multiple Gigabit Ethernet ports, as well as at least one SATA connector, and in some cases an mPCIe connector for WiFi or LTE cards. THe company also launched Banana Pi BPI-W2 board a few months ago, but that model is more geared towards multimedia router use cases. The company has now unveiled Banana Pi BPI-R64 router board based on Mediatek MT7622 dual core Arm Cortex-A53 processor, five Gigabit Ethernet port, on-board 802.11ac WiFi, one “laptop” SATA port, as well as an optional PoE (Power-over-Ethernet) add-on board.Banana PI RPI-R64 board specifications provided by the company – which has not always shown to be accurate -: SoC – MediaTek MT7622 dual-core Arm Cortex-A53 @ 1.35GHz with dedicated network accelerator, 4×4 802.11n and Bluetooth …

Linux 4.17 Release – Main Changes, Arm & MIPS Architectures

Linus Torvalds released Linux 4.17 last Sunday: So this last week was pretty calm, even if the pattern of most of the stuff coming in on a Friday made it feel less so as the weekend approached. And while I would have liked even less changes, I really didn’t get the feeling that another week would help the release in any way, so here we are, with 4.17 released. No, I didn’t call it 5.0, even though all the git object count numerology was in place for that. It will happen in the not _too_distant future, and I’m told all the release scripts on kernel.org are ready for it, but I didn’t feel there was any real reason for it. I suspect that around 4.20 – which is I run out of fingers and toes to keep track of minor releases, and thus start getting mightily confused – I’ll switch over. That was what happened for 4.0, after all. As …
