Raspberry Pi’s VideoCore 4 GPU Driver Added to Linux Mainline in Kernel 4.4

While your x86 and AMD64 computer will usually boot with Linux mainline without issues, most ARM boards and device won’t, and many of the ones that do boot only support headless mode, and limited functionalities. The Raspberry Pi had been supporting HDMI output with a simple framebuffer for a while, but a developer working on the Videocore 4 (VC4) GPU found inside Broadcom BCM2835 and BCM2836 processors, has recently submitted a patchset to add VC4 GPU to Linux mainline that should make it to Linux 4.4. The commit message does mention some features are still missing, but it’s a start: This pull request introduces the vc4 driver, for kernel modesetting on the Raspberry Pi (bcm2835/bcm2836 architectures). It currently supports a display plane and cursor on the HDMI output. The driver doesn’t do 3D, power management, or overlay planes yet. Via Golem and Sanders.

Converting H.264 Videos to VP9 In Linux / Ubuntu

1080p videos are all good, but my Internet connection’s upload speed is limited to 512 Kbps, so for example uploading a 20 minutes H.264 video shot at 1080p30 may easily take 10 hours, even after some processing with Handbrake. So this week-end I investigated how I could reduce the upload size, and going with H.265 codec appeared to be a good idea at first. So I tried again H.265 encoding in Handbrake in Ubuntu 14.04, and discovered that adjusting CRF (constant quality factor) to 25 with H.265 was roughly equivalent to 20 with H.264, and both the compression ratio and encoding speed were greatly improved compared to default settings with a minor degradation in quality. If you happen to have a second generation Nvidia Maxwell graphics card you may want to check Nvidia Video Encoding SDK for speedier encoding. All was good until I decided to upload a test video, […]

Run x86 Linux and Windows applications in Raspberry Pi and other ARM Linux Devices with Exagear

A few weeks ago, I finally decided to buy a Raspberry Pi 2 board as it could always be useful for some testing, at least for comparison purposes. I ended up buying it from Ebay for $40, as it’s $3 to $5 more expensive locally. Nevertheless, I was not sure what I’ll use it first for, but after seeing a tweet for Exagear Desktop software that allows ARM boards to run x86 Linux or Windows applications, the latter through wine. The program is available for Raspberry Pi, Raspberry Pi 2, and ARMv7 devices for $19.95 to $29.95. I asked for a version for testing purposes, and I was given a Google Drive link to download Exagear for Raspberry Pi 2, as well as a 3-month trial key. Installation is very easy. I started by downloading and installing Raspbian Jessie the usual way on a 32GB micro SD card. It went […]

Allwinner A64 Datasheet and User Manual Released

Allwinner has two 64-bit ARM processors in the works: Allwinner H64 and Allwinner A64. Both are quad core Cortex A53 processors with a Mali-400MP2 GPU, H.265 4K video playback with basically the same interfaces and peripherals, but H64 also supports H.264 at 4K resolutions, while A64 is limited to H.264 @ 1080p, and H64 adds a TS interface. The first good news is that two boards are in development: Orange Pi Plus 3 with Allwinner H64 Olimex A64-OLinuXino update with Allwinner A64 Engineering samples have already been produced for the first board, but that’s about all the information we have now, as Shenzhen Xunlong has not built its reputation by releasing documentation early. One the other hand, A64-OLinuXino schematics have nearly been completed, but we already know more details, as not only Olimex boards are open source hardware, but the company defies conventional wisdom by involving the community in the […]
