There's a growing number of features coming about for the Linux 3.5 kernel. Covered so far has been the DRM GPU drivers, input, input, and other areas. The ARM architecture has also been enhanced with Linux 3.5.
This weekend at LinuxTag 2012, an update was shared concerning the state of the Lima driver project -- the initiative to create a reverse-engineered, open-source ARM Mali driver.
ARM has published a new open-source X.Org DDX Linux graphics driver while working to enable support for their next-generation ARM Mali T6xx graphics core.
There is another new open-source Linux graphics driver entering development and it has already showed signs of success with basic 2D acceleration working. This new open-source driver is for Qualcomm's Snapdragon / Adreno and who is leading the development of this driver is also quite interesting.
The open-source ARM Mali graphics driver, known as the the Lima project, has achieved a major milestone. Since delivering the exclusive news of the Lima project as an open-source reverse-engineered ARM Mali graphics driver for Linux back in January, there hasn't been too much else to report on about this driver that's still early in its development life.
Besides the DRM work already piling up for Linux 3.4, there's more. The Samsung developers responsible for the Exynos graphics driver have sent in their "-next" pull request, which brings several new features, including the basis of 2D acceleration for this open-source ARM graphics driver. There's also a virtual display driver that could be used for handling wireless displays.
The recently announced KDE Spark Tablet has an ARM Mali 400 as its graphics processor, which right now is backed by a closed-source user-space driver but that's changing thanks to the Lima driver that's providing a reverse-engineered open-source ARM Mali driver. Here's a demo of the Lima driver's Limare stack running on the KDE Spark Tablet hardware.
The initial code push has taken place for the Lima Project, which is the open-source ARM Mali graphics driver that's under development. The Lima stack development is sponsored by Codethink and its lead developer is veteran X.Org developer Luc Verhaegen. Phoronix was the first to break the news on the project last month.
There's still one week until the work will be officially announced, but the open-source "Lima" open-source graphics driver project has surfaced. The Lima driver? This is going to be the open-source driver built for ARM's Mali graphics processors. Lima is what the project's being called for the story Phoronix exclusively broke last week, An Open-Source, Reverse-Engineered Mali GPU Driver.
There is some exciting news to break today on Phoronix... Coming up at FOSDEM (the Free Open-Source Developers' European Meeting in Brussels) will be the formal announcement of an open-source, reverse-engineered graphics driver for the ARM Mali graphics processor. OpenGL ES triangles are in action on open-source code. Will this be the start of fully open-source ARM graphics drivers for Android and Linux?
OpenFIMG, the open-source graphics driver project that began as the GLES6410 driver for providing a full open-source 3D stack for some Samsung ARM SoCs, continues to be developed and is moving on with its OpenGL ES accelerated support.
Last month at XDC2011 Chicago, I managed to get my hands on what should be the production hardware model of the XO-1.75 laptop that is expected to be released in the coming months by the OLPC project. The low-cost OLPC laptop targeted for students is now ARM-based and consumes very little power.
It seems that Samsung is quite interested in pushing upstream Linux kernel support for their ARM-based Exynos 4210 SoC. Besides pushing an open-source DRM kernel graphics driver, they have been working on other areas of upstream Linux kernel support for this SoC that employs a dual-core Cortex A9.
Samsung has published the code to a new open-source DRM driver for its EXYNOS4210 System-On-a-Chip. The EXYNOS4210 has impressive 3D graphics capabilities, uses the dual-core ARM Cortex A9 processor, and is used in various smart-phones. The Samsung Galaxy S II is one of the smart-phones using the Exynos 4210 SoC. Samsung is hoping to push this DRM driver into the mainline Linux kernel.
