Most of you know this already, but: hybrid graphics, the technology concept of having dual GPUs (generally a low-power IGP and a high-performance discrete GPU) and being able to seamlessly switch between them depending upon load and battery life, is a mess under Linux. It will continue to be a mess for the near-term.

Back in the middle of August HP said they would be selling their PC business and also discontinuing operations for their webOS devices and exploring what to do with their webOS software stack. Today Hewlett-Packard has announced they will actually be keeping their PC business.

One of the many OpenBenchmarking.org features that haven't yet been fully taken advantage is the opportunities presented by the vast collection of system hardware/software information and logs that have been submitted to this collaborative testing platform from Phoronix Media. OpenBenchmarking.org is much more than just being a storage place for benchmark results. After writing a simple plug-in this morning, here's a list of many motherboards that have broken PCI-E Active State Power Management support from their BIOS, which can lead to greatly increased power consumption under Linux.

The worst problem with Munich's Oktoberfest is not related to the beer or drinking too much of it (at least not from my perspective, with being able to properly and responsibly consume Augustiner), but rather having to deal with O2 Germany, the European tele-communications company.

While Texas Instruments released an open-source driver last year for the Linux kernel within the DRM area (the TILER driver), it didn't make it into the mainline tree for the lack of open-source user-space applications/drivers that could take advantage of it, i.e. the usual ARM graphics mess. Yesterday, however, Texas Instruments released a new open-source DRM driver for their OMAP platforms.

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.

While Oracle is most often criticized since their acquisition of Sun Microsystems for shafting the open-source community, in particular for OpenOffice, MySQL, OpenSolaris, and other projects, not everything they do is bad for open-source and Linux. They have VirtualBox, various kernel developers, Chris Mason works for them on Btrfs, etc. They also still employ some graphics developers. One of these developers for some time now has been working on improving the GPU memory management situation in virtualized environments.

The mobile device landscape, particularly for those devices running Linux, is quickly evolving. Just in the past few days, Google bought Motorola, Qualcomm open-sourced the remainder of their Gobi API for controlling modems, and HP ended off all their webOS devices, among other changes. But will the future mobile Linux device landscape deal with more open-source drivers, particularly when it comes to graphics?

With Hewlett Packard's Q3'2011 earnings that were just released, they have just revealed a couple major news items. HP has confirmed the news that began spreading this morning that they are looking to sell or spin off its personal computer business. They also confirmed they are looking to buy Autonomy Corporation. The surprise news, however, is that HP will be discontinuing operations for webOS devices such as the TouchPad and Pre smart-phone.

While we don't normally talk about Android news, this Monday morning Google has made a particularly interesting announcement that affects their mobile Linux operating system as well as hardware. Google has just announced they will be acquiring Motorola Mobility at a price of around 12.5 billion USD.

Ubisoft, the massive video game publishing and development studio, has been busy playing with Linux. In particular, exploring opportunities presented by Xen virtualization with regards to VGA pass-through as a means of decent gaming performance in a virtualized environment. A discussion began in the Phoronix Forums yesterday about Ubisoft's Xen VGA pass-through demo.

A new open-source DRM graphics driver has appeared in the embedded space. Sascha Hauer with Pengutronix has released the initial DRM base driver for the i.MX IPUv3 as found in the i.MX51 and i.MX53 SoCs. This driver supports the SoC units necessary for frame-buffer support.

CERN, the European organization behind nuclear research and the well-known Large Hadron Collider, has released a new version of its Open Hardware License. Version 1.1 is this new OHL release, which seeks to provide "a legal framework to facilitate knowledge exchange across the electronic design community."

HTC, one of the popular Taiwan-based mobile phone vendors, is going to be acquiring S3 Graphics from VIA Technologies. For around $300 million USD, HTC will have its hands on S3 Graphics and their intellectual property portfolio.

Even after using the Linux 2.6.38 kernel power regression workaround for those systems affected by the ASPM (Active-State Power Management) bug that was detected by Phoronix, some Linux users still don't have their netbook/notebook battery lasting as long as they'd wish. For some, Microsoft Windows 7 is still performing better on the battery and/or Ubuntu 10.04 LTS and earlier. As I've said, there's still at least a couple more Linux power regressions and other areas for optimization that I've discovered and still haven't yet publicly documented in full, some in part due to still analyzing what's happening.

Jesse Barnes, the maintainer of the PCI subsystem for the Linux kernel and one of the developers who signed-off on the patch that I discovered is causing the major Linux 2.6.38 kernel power regression, has commented on the matter.

Nailing down the Linux kernel power regressions (see Linux Has Major Power Regression and Another Major Linux Power Regression Spotted) has made a big step forward this weekend. Not only to fix up these major kernel power regressions that are hitting many mobile Linux users, but to look further into the state of Linux power management is now possible and to closely analyze other areas of the Linux stack to find other areas for improvement.

Embedded GPUs on Linux are a big mess due to their lack of fully open-source drivers, memory management complications, and other technical issues. However, there is some good news to report today and that's on the emergence of a new open-source KMS driver.

It was back in May of 2009 that DisplayLink began providing open-source Linux support for their USB-interfaced graphics processors in the form of documentation and code. Shortly thereafter, frame-buffer and X.Org drivers for DisplayLink USB hardware arrived and it quickly matured. By early 2010 it was possible to produce interesting results with these USB graphics adapters doing things like driving nine monitors over USB from a single computer.
