Re: [PATCH] xserver: add udev/systemd multi-seat support
http://www.freedesktop.org/wiki/Software/systemd/multiseat Hi Lennart, this patch caused a build regression on our RHEL6 builder, http://tinderbox.x.org/builds/2011-09-27-0006/logs/xserver/#build Can you please provide a patch to fix the build against older udevs, and just not do multi-seat in that case probably. or else we'll have to revert this.

[Pull Request] Glamor: A 2D rendering acceleration implementation based on OpenGL
Hi Keith, Here is the pull request to merge glamor. Basically, it has three parts. The first part is the 2D rendering acceleration implementation in glamor directory. It supports both OpenGL/GLESv2. The second part is in hw/kdrive/xephyr. This part integrate glamor into Xephyr. And by specify a -glamor when invoke the Xephyr then you can use glamor to accelerate the rendering operations. The third part is in hw/xfree86/glamor. This part implements a standalone ddx driver based on glamor, egl and kms. With this glamor driver, you can start up a Xserver over Mesa/EGL directly, without any native window system. Here are some instructions for how to build and use glamor: 1. Xephyr over glamor. Firstly configure Xephyr as below: #./autogen.sh --prefix=/opt/xserver-glamor --disable-glx --enable-kdrive --enable-xephyr --enable-glamor Then build and install the Xephyr. Then start a xserver which has glx support. Then invoke the Xephyr within the X env: #Xephyr -glamor 2. Standalone glamor ddx over EGL + KMS. Firstly we need to build mesa, the prefer version is git master. Build MESA as below (disable gallium, enable egl drm platform and must enable gbm.) #./autogen.sh --prefix=/opt/xserver-glamor --with-egl-platforms=drm --with-gallium-drivers= --enable-shared-glapi --enable-gles2 Then build and install the mesa library. Secondly configure Xorg as below: #./autogen.sh --prefix=/opt/xserver-glamor --disable-glx --enable-glamor --enable-glamor-ddx Then build and install this Xorg. And invoke it as below: #startx -- /opt/xserver-glamor/bin/Xorg You can check the /opt/xserver-glamor/var/log/Xorg.0.log to find the following words: Standalone glamor: OpenGL accelerated X.org driver which indicates the glamor ddx driver is running. Restrictions: 1. Not fully support glx. Glamor ang glx both need to create and maintain gl contexts. I haven't find a way to make them co-exist concurrently peacefully. One workaround is to rename those function names in glx/glapi.c and that will break the indirect glx rendering. But the direct rendering works fine with this workaround. This pull request doesn't has that workaround, so to enabling glamor, you must disable glx when build the xserver. 2. Not fully support DRI2. Gbm and mesa drm image extension don't support allocate dri2 buffers, especially for those Y-tiled buffers. So we can't support dri2 by using standalone glamor ddx driver. One workaround is to integrate glamor to current 2D driver, let the 2D rendering go to glamor and the other functions still use the original 2D drivers. We can borrow original 2D driver's buffer management to allocate dri2 buffers, and then bind those buffers to EGL KHR images, and then we can easily use glamor to rendering on those buffers directly. Discussed with Kristian on this restriction, and the conclusion is that we may hack the MESA buffer allocation to export those dri2 buffer allocation APIs to glamor. I will publish my modified xf86-video-driver-glamor latter on my personal repository which utilize glamor and support DRI2 and direct glx rendering. 3. Only support Intel platform currently. As glamor depends on KMS + MESA/EGL + GBM, currently only intel gfx device get supported. At last Just as Eric said, glamor's development has gone on for a long time without cleaning up and getting code merged, we have to submit this very long patch list here . I know this is inconvenient for the community to review, but I really have little choice. Anyway, please help to check it. Any comments are welcome. Thanks. The following changes since commit 7fb4bef0394a5d09680985d34bce8252b61493cb: Merge remote-tracking branch 'mattst88/for-keith' (2011-09-21 14:34:27 -0700) are available in the git repository at: git://people.freedesktop.org/~gongzg/xserver-glamor glamor Eric Anholt (100): Add build infrastructure for glamor. More ephyr/glamor glue. Add exa/glamor to _DEPENDENCIES so the bin gets rebuilt with the libs. glamor: Use -lgl for Xephyr if GLX is unset. glamor: Start trying to hook up the rendering bits glamor: Use a nicer struct initializer for gcops. glamor: glFlush from the blockhandler so rendering happens. glamor: first real attempt at rendering. ephyr: merge the host glamor bits into hostx. add fill files, merge with first real attempt at rendering. ephyr: Make sure a glamor-using window is created with a glx visual. ephyr: Use GLEW. glamor: Fix up block/wakeup handler. glamor: remove gratuitous flush. glamor: Fix up DrawPixels arguments to bear some relation to reality. glamor: Move to using shader objects. glamor: Add getspans implementation. glamor: Maybe fix up the format/type for setspans. glamor: Create FBOs for pixmaps. glamor: Fill out glamor_get_color_4f_from_pixel() a bit. glamor: Add untested support for tile filling. glamor: Free resources when destroying pixmaps. glamor: Add stub

I am not very familiar with either cairo/pixman, just know that it is used in spice, and it has a GL backend. There is also clutter, and some other open source 2D GL rendering libraries (qt canvas is also interesting, although I guess it's C++). How is glamor related to them? (I guess some of them don't support EGL, but looking at those who do - clutter certainly, runs on my n900, and qt as well I think).

Re: net-color spec renamed to X Color Management
