Linux ARM driver

  • Linux on ARMThe Lima driver is slowly but surely progressing for supporting ARM Mali graphics hardware in an open-source world. A Mesa driver has been started, their demo code can be faster than the binary driver, user-space memory management is being tackled, and evidently the management at ARM Holdings isn't too happy.

  • Linux on ARMQualcomm developers have posted their new mac80211 driver for the Qualcomm Atheros QCA98xx 802.11ac wireless adapters for use with the Linux kernel.

  • Linux on ARMLast year was the landmark announcement of an open-source NVIDIA Tegra graphics driver for Linux that was developed with the support of NVIDIA. In late November, NVIDIA published open-source 2D acceleration support for their newer ARM SoCs. Today, 3D support is being announced for the open-source NVIDIA Tegra graphics driver.

  • Linux on ARMThe 2D graphics acceleration support for NVIDIA Tegra 2 and Tegra 3 ARM SoCs is still maturing and going through code revisions before entering the mainline Linux kernel, hopefully for Linux 3.10.

  • Linux on ARMThe first working ARM System-on-Chip (SoC) GPU graphics driver built for Gallium3D has been merged into mainline Mesa! The driver that was merged into mainline Mesa is the Gallium3D Freedreno for Qualcomm Snapdragon/Adreno graphics hardware. This Freedreno Gallium3D driver initially supports the A220, which is the GPU that Qualcomm uses with its Snapdragon S3 SoC.

  • Linux on ARMhe Linux 3.9 kernel will be another exciting update not only for common x86 users but the ARM hardware support continues to advance too. The 3.9 ARM SoC pull was sent in on Thursday by Arnd Bergmann. Among the noteworthy updates this time around include:

  • Linux on ARMThe Texas Instruments' OMAP DRM pull request for the Linux 3.9 kernel is now known. The OMAP DRM graphics driver will leave the kernel's staging area while at the same time picking up support for the OMAP5 SoC.

  • Linux on ARMAs I previously wrote, FOSDEM organizers are slowly uploading FOSDEM 2013 videos. One of the most interesting talk "Open ARM GPU Drivers" is now available. I've also uploaded it to YouTube (embedded below) to give it more exposure. Luc Verhaegen has also written a recent blog post entitled "Hey ARM!" where he announces the release of the modified source for Quake 3 Arena demo, and asks ARM to join them in making an open source driver.

  • Linux on ARMLuc Verhaegen has warned ARM that his Lima graphics driver project will only "grow louder and louder" as its performance becomes more competitive with their closed-source Mali graphics driver and eventually may reach (or surpass) feature parity.

  • Linux on ARMAn update on the open-source NVIDIA Tegra graphics driver was shared this weekend in Brussels. The Tegra DRM driver was merged and there's more features to be implemented in succeeding releases. Unfortunately, open-source 3D support for NVIDIA's ARM hardware isn't yet on the radar.

  • Linux on ARMWhile xf86-video-sunxifb sounds like an old X.Org driver from the Sun Microsystems days for some obscure SPARC system, this driver is a fork of the xf86-video-mali DDX driver. What makes this ARM X.Org graphics driver interesting is that it promises better performance on the Allwinner A10/A13 SoC compared to the ARM vendor's official driver.

  • Linux on ARMThe latest bi-weekly release of the Wine software, v1.5.22, has a couple of interesting features. The official change-log for Wine 1.5.22 as released today cites the following highlights:

  • Linux on ARMEtnaviv is a new open-source project for building a user-space graphics driver for controlling the Vivante GPUs found in some ARM SoCs. The ultimate goal is to create a new Mesa/Gallium3D driver for this graphics core.

  • Linux on ARMPiglit is a collection of automated tests for OpenGL implementations that aims at improving the quality of open source OpenGL drivers by providing developers with a simple means to perform regression tests.

  • Linux on ARMRob Clark has provided a status update on Freedreno, his reverse-engineered ARM open-source graphics driver for the Qualcomm Snapdragon / Adreno hardware.
     

  • Linux on ARMThe popular budget-friendly Raspberry Pi ARM development board now has a fully open-source graphics stack -- the user-space graphics drivers for the Broadcom VideoCore included!

  • Linux on ARMIt appears that Samsung is preparing to open-source some code pertaining to their Exynos ARM SoC. At an event this weekend (YouTube stream), Samsung said they will open-source the kernel and platform components of their Exynos SoC. This new code is said to be dual-licensed under the GPLv2 and Apache 2.0 licenses.

  • Linux on ARMLinus Torvalds announced yesterday, October 14th, the immediate availability for download of the first released candidate for the Linux 3.7 kernel series. Linux kernel 3.7 RC1 comes with a lot of new features, according to Linus Torvalds. Among the listed changes, we find that now the "uapi" includes file cleanups.

  • Linux on ARMNearly two months ago I wrote that a major open-source ARM announcement was coming. "This forthcoming announcement, which isn't being detailed yet but will be yet another Linux graphics exclusive for Phoronix the near future, is something entirely different from the other recent open-source ARM Linux graphics advancements" So what's the announcement?

  • Linux on ARMTexas Instruments has published their initial Linux kernel patches for providing support for their forthcoming Keystone platform, which is an interesting ARM-based platform dealing with many-core SoCs using Cortex-A15s.
