Linaro 14.09 Release with Kernel 3.17 and Android 4.4.4

September 27th, 2014 No comments

Linaro 14.09 has just been released with Linux kernel 3.17-rc4 (baseline), Linux 3.10.54 & 3.14.19 (LSK), and Android 4.4.2 & 4.4.4.

Linaro has kept working on their member boards such as IFC6410 (Qualcomm), D01 (Huawei/Hisilicon), Ardnale (Samsung), and Juno (ARM). They’ve also announced they’ll change the tools to build GCC by using cbuild2 instead of cbuild1 for next release, and they’ve enabled a build with gcov (for code coverage analysis) which may mean they’ll work on reducing the kernel size by getting rid off unused code. I’ve also noticed the Arndale and Arndale Octa Ubuntu images are now based on Linux LSK with Mali GPU support since last month.

Here are the highlights of this release:

  • Linux Linaro 3.17-rc4-2014.09
    • GATOR version 5.19
    • updated topic from Qualcomm LT (ifc6410 board support) and HiSilicon LT
    • updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT.
    • updated Versatile Express patches from ARM LT
    • updated LLVM topic (follows the community llvmlinux-latest branch)
    • Big endian support (the 2014.05 topic version rebased to 3.17 kernel)
    • config fragments changes – added gcov config fragment, disabled DRM_EXYNOS_IOMMU to work around boot failure on Arndale
  • Linaro Toolchain Binaries 2014.09
    • based on GCC 4.9 and updated to latest Linaro TCWG releases: Linaro GCC 4.9-2014.09, Linaro binutils 2.24-2014.09, and Linaro GDB 7.8-2014.09.
    • This will be the last release done with cbuild1 and crosstool-ng. Next releases will be done with cbuild2. Official support for very old host environments will be dropped.
  • Linaro builds of AOSP 14.09 built with Linaro GCC 4.9-2014.09.
  • Linaro OpenEmbedded 2014.09
    • integrated Linaro GCC 4.9-2014.09, Linaro binutils 2.24-2014.09, integrated Linaro GDB 7.8-2014.09.
    • imported Linaro eglibc 2.19 into meta-linaro after OE-core switched to glibc 2.20
    • fixed shadow securetty for Qualcomm and STMicroelectronics SoCs
    • upstreaming – fixed libpng on aarch64 (neon symbol), updated PM QA to 0.4.14, updated libunwind to include aarch64 support
  • Linaro Ubuntu 14.09
    • added linux-tools (perf standalone, splitted from kernel build)
    • updated packages: Juno firmware 0.8.1, LSK 3.10.55/3.14.19 and linux-linaro 3.17-rc4 kernels.
  • A gcov enabled build has been added
  • Linaro builds of the Android NDK have been updated to current upstream sources and current Linaro toolchain component releases.
  • Standalone Android toolchain binary builds now use Linaro binutils for improved armv8 support.

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

January 23rd, 2014 2 comments

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 increased size requires extra bandwidth, as well as more energy. In order to reduce the size of textures and power consumption, textures are normally compressed by the GPU. The demo below compares compression and energy consumption of raw textures, ETC2 compressed textures and the new ASTC compressions. The hardware is a Samsung Galaxy Note 3 with Exynos 5 Octa 5420 using a Mali T-628 GPU.

  • Raw textures – Size: 263 MB. Power consumption – DDR3: 2.732 mJ/frame, DDR2: 3.32 mJ/frame
  • ETC2 compression – Size: 93 MB. Power consumption – DDR3:  1.387 mJ/frame, DDR2: 1.687  mJ/frame
  • ATSC compression – Size: 49 MB. Power consumption – DDR3: 1.101 mJ/frame, DDR2: 1.330 mJ/frame

In this demo, ATSC almost doubles the compression ratio, and consumes about 20% less energy. There’s also less differences from the raw texture with ATSC compared to ETC2.

Gesture Recognition with XBMC

The next demo show OpenCL accelerated Eyesight gesture recognition in Arndale board powered by Exynos 5250 SoC with ARM Mali-T604. The board runs Linux and is connected to a standard (and crappy) Logitech webcam. It can follow hand gestures with OpenGL acceleration, something that is not possible with the dual core Cortex A15 CPU only. They’ve also integrated the demo with XBMC, and showed how to navigate XBMC user interface with your hand only, no remote needed.

HEVC / H.265 Video Decoding

The last demo is also running Linux on Arndale board. They show H.265 decode with the GPU thanks to Ittiam implementation.
