Mali-400 GPU Is Now Working in Linux for Rockchip RK3188 Devices

Accelerated 3D graphics in Linux with Mali-400 via OpenGL ES has been possible for nearly a year on RK3066 devices,  but there was no such support for RK3188. This week however, both Naoki FUKAUMI and omegamoon have reported OpenGL ES to work in in their respective RK3188 devices. I don’t know which device omegamoon used, but Naoki did so in Radxa Rock, and even posted instructions to build it yourself. They’ve mostly followed the work done by olegk0 for Rockchip, and Mali drivers build instructions provided in linux-sunxi community, and it can be summarize in 3 main steps: Cross-compile drm.ko, mali_drm.ko, ump.ko, mali.ko in a Linux machine Copy and load the four modules to your RK3188 based board or device. Install dependencies and binary Mali drivers from sunxi-linux in your Rockchip device Once this is done you can try some OpenGL ES demos such as esgears2 or glmark2-es to test […]

Amlogic GPL Source Code Release – Kernel 3.10, U-Boot, and Drivers (Wi-Fi, NAND, TVIN, Mali GPU)

Last month, I noticed Amlogic provided links to the Android SDK for S802 / M802 on their open source website, but the only way to get the source was to share your SSH public with Amlogic, so that they give you access. It did not happen, but the company has released the source for Linux 3.10.10, U-boot 2011.03, Realtek and Broadcom Wi-Fi drivers, NAND drivers, “TVIN”drivers, and kernel space GPU drivers for Mali-400 / 450 GPU. There are also some customer board files for Meson 6 only (AML8726-MX / M6) but they do not seem to match the kernel… If you want to build the kernel, including the drivers, you’ll need to download a bunch of files: wget wget wget wget wget wget wget wget wget wget wget You’ll need to extract these tarballs in specific directories:

Raspberry Pi Gets Open Source 3D Graphics Drivers and Documentation

The Raspberry Pi was launched 2 years ago, and for its birthday, Broadcom decided to release documentation and open source OpenGL ES 1.1 and 2.0 driver for the Videocore IV GPU.  You may remember the Raspberry Pi Foundation already release an open source GPU driver in 2012, but this was only for the part running on the ARM11 core for Broadcom BCM2835 SoC, which is just a few hundred lines of code long, and communicates with a binary blob which does all the work in the GPU itself. This new release however goes much further with a 111 page document entitled “VideoCore IV 3D Architecture Reference Guide“, and open source driver for the 3D System of the GPU. Strangely the release is however not for BCM2835, but instead BCM21553. Broadcom clearly has the source for BCM2835 too, so this must have been made for legal reasons. VideoCoreIV packs a lot […]

Intel Bay Trail Graphics Overview – FOSDEM 2014

Bay Trail SoCs are new low power Intel ICs for tablets (Bay Trail-T, Z3000 series), mobiles (Bay Trail-M, N2800, N2900 and N3500 series), desktops (Bay Trail-D, J1800, J1900 and J2900 series) and embedded / industrial platforms (Bay Trail-I, E3800 series). Many Atom processors used to features PowerVR GPU, but it has now been replaced by Intel HD graphics in Bay Trail SoC. Jesse Barnes, working at Intel on software and drivers for Intel graphics devices, gives a presentation about Bay Trail SoCs with a focus on graphics. After an overview, and some ARM bashing regarding performance (Nvidia Tegra 4 and Qualcomm Snapdragon 800), and even power consumption (Tegra 4 only), he describe further details about Intel HD graphics found in the new Intel processors. Everything is basically in mainline, and you’ll need Linux 3.10 or greater, Mesa 9.2 or greater, and libva 1.2.1 or greater for proper support. Some initial […]

ARM Unveils Cortex A17 Processor, First Used in Mediatek MT6595 and Rockchip RK3288 SoCs

Finally all these ARM Cortex A17 marketing materials for Rockchip RK3288 were not some typos, but Rockchip marketing team may just have not received the memo reading “Confidential”, as ARM has now officially announced Cortex A17 processor based on ARMv7-A architecture, with support for big.LITTLE with Cortex A7, and that can be coupled with Mali-T720 mid-range GPU and Mali-V500 VPU. After Cortex A15, and Cortex A12, you may wonder “Why? But Why did ARM had to launch yet another new core?”. Here’s the company answer to that question: The Cortex-A17 processor offers 60% performance uplift over the Cortex-A9 processor, the current leader in mid-range mobile market, and betters the best efficiency enabling optimized solutions to address existing and new products. The Cortex-A17 processor is based on the popular ARMv7-A architecture, today’s most successful architecture in the mobile market. With over 1M apps supporting the ARMv7-A architecture, the Cortex-A17 processor is […]

ARM Mali GPU Demos at CES 2014 – 4K 3D UI and Games, ASTC Texture Compression, XBMC + Gesture Recognition, and HEVC Video Decoding

Phill Smith, Demo Manager at ARM, has filmed and uploaded four very interesting demos of what new features will be possible thanks to new generation ARM Mali-450 and Mali-T6xx GPUs including 4K 3D user interfaces and games, ASTC texture compression, and OpenCL accelerated gesture recognition and HEVC / H.265 video decoding. 4K Resolution 3D User Interface and Game Demo The first demo showcases a Geniatech box (ATV1800?) powered by AMLogic AML8726-M8 featuring an ARM Mali-450MP6 GPU running Android with a user 4K 3D interface designed by Autodesk using Scaleform UI. The rest of the video shows Timbuku 3D gaming demo running at 3840×2160 (4K2K) @ 24 fps. The frame rate appears to be low, but that’s because the box is using HDMI 1.4, which limits UHD output to 24fps. 2160p60 is only available via HDMI 2.0. ASTC Compression Demo on Samsung Galaxy Note 3 3D Textures are getting bigger and […]

Linux Kernel 3.13 Release

Linus Torvalds announced the release of Linux Kernel 3.13 yesterday: The release got delayed by a week due to travels, but I suspect that’s just as well. We had a few fixes come in, and while it wasn’t a lot, I think we’re better off for it. At least I hope so – I’ll be very disappointed if any of them cause more problems than they fix.. Anyway, the patch from rc8 is fairly small, with mainly some small arch updates (arm, mips, powerpc, s390, sparc, x86 all had some minor changes, some of them due to a networking fix for the bpf jit). And drivers (mainly gpu and networking). And some generic networking fixes. The appended shortlog gives more details. Anyway, with this, the merge window for 3.14 is obviously open. Kernel 3.12 brought new features to BTRFS and XFS file systems, PC’s GPU drivers improvements, better memory handling, […]

Tegra K1 based Devices Could be Just as Fast as Mid Range Intel Core i5 Laptops

Some benchmark results comparing Nvidia Tegra K1 reference tablet to Intel based laptops show the latest ARM SoC matches and even outperforms many Intel devices, at least when it comes to 3D performance thanks to the 192-core Kepler GPU found in Tegra K1. In T-Rex HD Offscreen test in GFXBench 2.7.5, Tegra K1 is hown to be about 4 times faster than Tegra 4, over twice as fast as Qualcomm Snapdragon 800, and interestingly it outperforms some Intel laptop such as Acer Aspire V5-573G powered by an Intel Core i5 4200U processor with HD Graphics 4200 GPU. It’s still twice as slow as a machine with an Intel Core i7-4000MQ and Geforce GT 740M. CPU performance will probably be equivalent to some Intel Core i3 machine however, at least for the quad core ARM Cortex 15 version, but that still probably means it’s very likely we’ll find computers and laptops […]
