Android Can Now Boot with a Full Open Source Graphics Stack on NXP i.MX6 Boards

While the Android operating systems is itself open source, it still relies on proprietary binary files to leverage GPU acceleration, VPU hardware decoding, wireless connectivity, and so on. It’s been possible to run Android with an open source software graphics stack, but it’s normally terribly slow and barely usable. But Collabora has announced it could now boot Android with a full-graphics stack on iMX6 platforms using no proprietary blobs at all. To do so, they leveraged the work done on Etnaviv open source drivers for Vivante GPUs, and adding the different formats used for graphical buffers in Android and Mesa library using modifiers representing different properties of buffers. They further explain: Support was added in two places; Mesa and gbm_gralloc. Mesa has had support added to many of the buffer allocation functions and to GBM (which is the API provided by Mesa, that gbm_gralloc uses). gbm_gralloc in turn had support […]

Open Source Code Released for Hisilicon Kirin 960 Based Huawei Mate 9 and Huawei P10 Smartphones

Manufacturers of products using open source software are normally required to release the source code with their modifications to follow licenses such as the GPL, but not all comply with the license. Huawei has now released the source code with Linux and other open source libraries and programs for their Huawei Mate 9 / Mate 9 Pro and Huawei P10 / P10 Plus models powered by Hisilicon Kirin 960 processor. With the release of Hikey 960 development board most of the source code for Kirin 960 should already be available, but it’s possible some drivers/modules specific to Huawei phones may be found instead of in the Huawei release. You’ll find the download in Huawei’s open source page for: Huawei Mate 9 (MHA) / Mate 9 Pro (LON) – Link to downloads Huawei P10 (Victoria) / P10 Plus (Vicky) – Link to downloads I picked up the LON-NG_EMUI5.0_opensource.tar.gz tarball for Mate […]

MCUBoot is an Open Source Secure Bootloader for IoT / MCUs

Bootloaders takes care of the initial boot sequence on the hardware before the operating system takes over. For example, U-boot is often used in embedded systems as the bootloader before starting the main operating systems such as Linux or FreeBSD. MCUBoot is also a bootloader, but it targets the IoT, here referring to MCU based systems with limited memory and storage capacity, and is born out of work on Apache Mynewt OS, when developers decided to develop the bootloader separately from the operating system. MCUBoot is designed to run on small & low cost systems running on MCU with ~512 KB flash, ~256 KB RAM, and currently supports Zephyr OS and Mynewt, with support for other RTOS also considered. Due to constraint the bootloader uses minimal features with a flash driver, a single thread, and crypto services. The project also aims at solving security and field firmware updates. To address the […]
