Two days ago there were some ATI R300 GLSL compiler optimizations made to the open-source Radeon driver stack by Tom Stellar as part of his Google Summer of Code project as a student developer to improve the R300 GLSL compiler support. This code is still living in a branch outside of Mesa, but some progress has been made. Though the R300 GLSL compiler optimization work was just one of five projects that were part of the 2010 Google Summer of Code for X.Org. Here's a few words on the other student projects.
A few weeks ago we reported that notebook hybrid graphics switching on Linux still sucks. For these newer laptops that boast dual GPUs -- an integrated low-power IGP and a more performance-oriented discrete GPU for demanding environments with switching between the two being done "seamlessly" in real-time based upon usage or via a hot-key -- the support under Linux is still virtually nonexistent. There is a crude form of Linux GPU switching, but for the most part it's not nearly up to par for what's available in Microsoft Windows 7 or Apple Mac OS X. The situation remains that way, but some small progress has been made.
While NVIDIA may not be focusing upon supporting the Wayland Display Server at this time, they are continuing to focus upon improving the experience of their driver with the X.Org Server. Three months after putting out their most recent X Sync object patches, they are now out with a revised set.
Haitao Feng, a software engineer at Intel China believed to be working on MeeGo, has come forward seeking clarification on the future of Xephyr and KDrive. Intel is still interested in Xephyr and Haitao is willing to maintain it, especially after doing work to add OpenGL acceleration to this KDrive-based X Server that targets a host on another X Server as it's frame-buffer.
Just over a week ago we reported on Pixmain gaining improved gradients and is rendering much faster in the project's latest development release. Now this free software project that provides pixel manipulation capabilities for the X Server and Cairo, has reached its version 0.20.0 stable milestone.
Apple's Jeremy Huddleston released X.Org Server 1.9.1 this past weekend, and now he has laid out plans for the next point release in the xorg-server 1.9 series. This release will carry the same type and quality of fixes as presented in X.Org Server 1.9.1 and should be released in December.
Mario Kleiner has published patches over the weekend that introduce precise vblank time-stamping support within the Linux kernel's DRM core and has implemented this support already within the Radeon and Intel kernel drivers too. The precise vblank timestamps and counting is needed by the DRI2 sync and swap extensions and in particular to conform with the OML_sync_control extension.
X.Org Server 1.9.1 was released yesterday, which led us to wonder about the status of the X.Org 7.6 katamari that was supposed to come at around the same time as this first stable point release. We hadn't heard anything about the X.Org 7.6 release schedule in weeks and before that the target to ship this grouped collection of X packages was mid-October, which has clearly passed.
As we mentioned earlier, Apple's Jeremy Huddleston took over release management of the X.Org Server 1.9 series now that it's stable and will only receive bug-fixes from this point on. Meanwhile, Keith Packard and the gang of X.Org developers are focusing on X.Org Server 1.10 to have that ready by early next year. Jeremy Huddleston on this Saturday night has just made his first point release, X.Org Server 1.9.1.
While Cairo is frequently mentioned on Phoronix, mentioned less but used by Cairo (as well as the X.Org Server) for pixel manipulation is the Pixman library. Soeren Sandmann announced a new release candidate of Pixman 0.19.6 this afternoon and it has a few interesting changes worth noting.
Takashi Iwai of Novell/SuSE has just published a series of 18 patches for the X.Org Synaptics input driver that primarily provides multi-touch support. There's also some fixes and other changes to this Synaptics driver for X, but the primary feature is the addition of multi-touch support under Linux (and other X.Org-using operating systems) for supported hardware.
Under the release management of Apple's Jeremy Huddleston, the first release candidate for the first point release in the X.Org Server 1.9 series is now available. X.Org Server 1.9.1 will be the first update to X.Org Server 1.9, which was released in August, and should make it out around the same time as the X.Org 7.6 katamari release later in October.
Besides talking about the X.Org Server development process and the X.Org Server 1.10 plans, Keith Packard also talked about not running the X.Org Server as root (also sometimes referred to as a "root-less X Server") during XDS Toulouse.
The 2010 X.Org Developers' Summit in Toulouse has been over for a week, but the disappointing weather in Munich today Oktoberfest finally made it sound more enticing to take care of the remaining XDS 2010 coverage rather than drinking Augustiner in a wet pair of lederhosens. With that said, below are the video recordings of when Keith Packard and Peter Hutterer were talking about the X.Org Server development process changes that have resulted in surprisingly on-time releases.
As a reminder to those interested in participating in our annual Linux Graphics Survey, there's now less than a week before this survey officially is over at month's end. This survey is meant to provides some quantitative data about what the Linux community is most interested in when it comes to graphics driver features and the hardware and drivers currently being most utilized, etc.
A few days back I reported on the first operating system where you may see the Wayland Display Server used rather than an X.Org Server after talking with Kristian Høgsberg while in Toulouse. At the X.Org Developer Summit' he talked to everyone about EGL in Mesa, which also plays an important role with Wayland.
The last talk of the 2010 X.Org Developers' Summit was regarding X.Org Server 1.10. The good news is that nearly every X.Org graphics driver will not be merged back into the xorg-server repository.
The X.Org Developers' Summit in Toulouse, France just ended and it's time in the morning to head to Oktoberfest to meet with many Phoronix readers at this annual outing. XDS 2010 turned out to be a wonderful event and more organized than some X.Org events in the past. Thanks to the wonderful organization by Matthieu Herrb, the venue itself was nice, the social event last night was terrific, the Internet and power at the event was plenty, etc. Stay tuned for Phoronix notes and some audio/video recordings to be published in the coming days, beyond what has already been reported. At XDS 2010 it was also brought up where to host XDS 2011.
While X Server 1.10 is not being discussed at length until tomorrow (the final day of XDS Toulouse), besides today's notes, Luc Verhaegen who formerly was with Novell working on the RadeonHD driver and has also worked on the open-source VIA Unichrome driver and a few other X related projects, is preparing for another heated battle.
More details will come later along with the audio/video recordings that ended out the X.Org Developers' Summit in Toulouse, but here are a few random bits from so far today:
Originally at the X.Org Developers' Summit here in Toulouse this week there was going to be a talk entitled "Kill It With Fire" where Corbin Simpson (mostly known for his work on the ATI R300 Gallium3D driver) was going to be speaking about what drivers or parts of X.Org should be eliminated from the stack. This talk though is no longer occurring, in part as Corbin is no longer in attendance; he washed his US passport in the laundry.
Scheduling issues had plagued X.Org Server development for the past few years: to the point that even delivering a point release had come more than a year late and major X Server releases were never delivered on time. This though has fortunately changed.
Matt Dew, a self-proclaimed "X newbie", just finished talking about his experiences as just entering the world of X.Org development and hopes to contribute to the X.Org world by gathering up and improving X.Org documentation.
XDS 2010 has just begun in Toulouse, France. Well, besides yesterday's pre-event where we were discussing Wayland and other topics. At the moment just the X.Org Foundation itself is being discussed.
While there are only a few days left until the 2010 X Developers' Summit, Keith Packard has laid out his plans for the development of X.Org Server 1.10.
For those interested in the X Developers' Summit (XDS) that is taking place next week at a tobacco factory in France, a tentative schedule has now been published by Matthieu Herrb for the 50 or so people that will be participating in the summit.
While there is Oktoberfest in two weeks, in just a week and a half there is the annual X.Org Developers' Summit. This year's summit for these developers is taking place in Toulouse, France. The event was going to be hosted at a conference room at the University of Toulouse, but due to delays in renovating that room, this X.Org summit has been moved to an ex-tobacco factory.
Two years ago we compiled a list of the top contributors to the X Server over the years and that was followed by compiling a similar list of the developers behind Mesa. Tiago Vignatti has now compiled some statistics surrounding the top contributors to X.Org Server 1.9 and related X components just looking at this most recent development cycle. There's also numbers for the input, video, and Mesa components too.
Earlier this month Canonical introduced its own multi-touch framework for Ubuntu that is set to premiere with Ubuntu 10.10 "Maverick Meerkat" and it's called UTouch and is joined by their own gesture/touch language. That same day as announcing UTouch for Ubuntu that will support devices like the Apple Magic TrackPad and Dell XT2, Canonical proposed the X.Org Gesture Extension to the X.Org development community. While it's good to see Canonical making more contributions to upstream projects that it depends upon for Ubuntu Linux, the X.Org Gesture Extension is already being re-evaluated and may in fact not be needed.
While X.Org Servger 1.9 was released less than a week ago (heck, it's only been four days since releasing om time), the first interesting patch for X.Org Server 1.10 is already queued up and on the X.Org development mailing list for discussion. This patch, which was written by Tiago Vignatti and Fernando Carrijo, provides the "thread-ification" of the X Server input event generation code. Rather than being bound to the same thread as the X Server, the input event code with this patch is now running in its own thread, but this may only be the start of things to come with finally multi-threading the X.Org Server.
