Linux 4.13 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has just announced the release of Linux 4.13 and a kidney stone…: So last week was actually somewhat eventful, but not enough to push me to delay 4.13. Most of the changes since rc7 are actually networking fixes, the bulk of them to various drivers. With apologies to the authors of said patches, they don’t look all that interesting (which is definitely exactly what you want just before a release). Details in the appended shortlog. Note that the shortlog below is obviously only since rc7 – the _full_4.13 log is much too big to post and nobody sane would read it. So if you’re interested in all the rest of it, get the git tree and limit the logs to the files you are interested in if you crave details. No, the excitement was largely in the mmu notification layer, where we had a fairly last-minute regression and some discussion about the problem. Lots of kudos to Jérôme […]

Rikomagic RKM R1 Mini Projector Review – Part 2: Android Firmware, Kodi, Touchpad, and HDMI Input

Rikomagic RKM R1 is a projector running Android 4.4.4, and powered by Rockchip RK3128 quad core Cortex A7 processor with 1GB RAM, and 32GB storage. It has a particular feature as it comes with a touchpad on the top of the case as we’ve seen in the unboxing and teardown part of the Rikomagic R1 review. Today, I’ll report my experience with the projector playing games in Android, 1080p videos with Kodi 14.2, using the touchpad, and connecting a laptop through the HDMI input port. I’ll also run some benchmarks as usual. RKM R1 Android User Experience and HDMI Input I wanted to relax and use the projector on the bed pointing to the ceiling. RKM R1 comes with a tripod, but it’s quite small, not the projector would fall off, so I used my own tripod, connected a USB keyboard, and the USB RF dongle for Tronsmart Mars G01 gamepad as I planed to play some games. I turned […]

Rikomagic R1 Android Projector Review – Part 1: Unboxing and Teardown

Rikomagic R1 Android mini projector runs Android 4.4 on Rockchip RK3128 quad core processor, and the company sent me a sample for review, so today I’ll first do an unboxing, and partial teardown, before testing the projector in more details in the second part of the review. Rikomagic R1 Projector Unboxing The projector comes with a white package marked RKM R1. The bottom of the package indicated its unsurprisingly based on Texas Instruments DLP technology with a LED light, and is equipped with a touch panel and a battery. More importantly, there’s a QR code that links to R1 Setup Guide, which for once will be useful, as this device has some unique features. The projector ships with a 5V/2.5A power supply, an IR remote control, a HDMI cable, a tripod, and an adapter to make the interface between the projector box and the tripod. The top of the device has a touch area, the front comes with the projector […]

Official Rockchip Github Account and Wiki Launched

Following the popularity of RK3066 and RK3188 processors in 2013, a community of developers for Rockchip Linux and Android development was created with corresponding linux-rockchip github account, mailing list and #linux-rockchip IRC channel, and now most of the information can be gathered from development board manufacturers like Firefly. However, I’ve just been pointed out to some VA-API driver for Rockchip RK32xx processor, on rockchip-linux (not linux-rockhip) github account, with the following tagline: An open source software for Rockchip SoCs, This site maintained by Rockchip The only person currently registered to this account, Jacob Chen (陈豪), is a software engineer working for Rockchip, so it does indeed look to be official. The github account also links to rockchip.wikidot.com with links to communication channels established by linux-rockchip community, and lots of entries about Linux, Android, U-boot, and so on, most of which are currently placeholders. So it still looks like work in progress, but maybe something to follow. Jean-Luc Aufranc (CNXSoft)Jean-Luc started […]

Eny EVR01 Android All-in-One Virtual Reality Headset Features Rockchip RK3126 Processor

I keep reading that in order to offer a pleasant user experience, virtual reality will require high resolution displays (4K or greater), and SoCs fast enough to handle all the extra data processing requirements, but some Chinese manufacturers are instead trying to enter the low end of the market with products such as Allwinner H8vr or HA544 which are way too weak to handle 3D graphics for VR applications in a satisfying manner, but could be good enough for watching 3D and VR video. Eny Technology has gone one step further (down) with EVR01 VR headset based on Rockchip RK3126 quad core Cortex A7 processor combined with a 5″ 1280×720 display. EVR01 AIO VR headset specifications: SoC – Rockchip RK3126 quad core Cortex A7 processor @ 1.3 GHz with Mali-400MP2 GPU System Memory – 1GB DDR3 (Optional 512 MB) Storage – 8GB flash (Optional: 16GB) + micro SD slot up to 64GB Display – 5″, 1280 x 720 resolution Lenses […]
