The new version<o:p></o:p>is 0.4, here are the details:<o:p></o:p><o:p> </o:p>= What's New =<o:p></o:p><o:p> </o:p>The latest version is 0.4. Here is the new features in this release:<o:p></o:p> 1. DRI2 now works well, and texture-from-pixmap also works well.<o:p></o:p> 2. Fully support glx including AIGLX, indirect glx's GL context<o:p></o:p> coexists with glamor's GL context safely. Thanks for Chris<o:p></o:p> Wilson's help to refine this function.<o:p></o:p> 3. Optimize most of the fallback path and avoid whole pixmap <o:p></o:p> downloading/uploading as much as possible.<o:p></o:p> 4. 1BPP picture uploading now will not fallback the whole rendering<o:p></o:p> path.<o:p></o:p> 5. Fully support all color formats for GLES2 port. Thanks for<o:p></o:p> Lipeng's contribution and testing for the GLES2 port on<o:p></o:p> PVR545 platform. And thanks Zhengyu to fix some PVR related problems.<o:p></o:p> 6. Fixed many of the bugs for cairo-test-suite, now we get almost<o:p></o:p> identical or even better result than UXA.<o:p></o:p> 7. Implemented a fbo/texture cache pool mechanism which will reduce<o:p></o:p> the overhead of texture/fbo destruction and creation, and bring<o:p></o:p> overall 15-20% performance improvement. On PVR545 platform, we<o:p></o:p> even get about 10x performance improvement with this feature.<o:p></o:p><o:p> </o:p>= How to Enable Glamor? =<o:p></o:p>To enable the Glamor, the following steps is needed:<o:p></o:p><o:p> </o:p> 1. Rebuild the mesa using the parameter:<o:p></o:p> --with-egl-platforms=x11,drm --with-gallium-drivers= --enable-gbm --enable-shared-glapi --enable-glx-tls<o:p></o:p> 2. Rebuild the xf86-video-intel driver, add parameter<o:p></o:p> --enable-glamor<o:p></o:p> to enable glamor module which is embedded in intel driver.<o:p></o:p> 3. Build and install glamor source.<o:p></o:p> 4. Make sure you have the xorg configure file named glamor.conf<o:p></o:p> at conf/glamor.conf under the directory<o:p></o:p> /usr/share/X11/xorg.conf.d or /etc/X11/xorg.conf.d/. <o:p></o:p> Although make install will try to install that file to the correct<o:p></o:p> directory. But it may failed, as if you are installing the xserver<o:p></o:p> to a local directory, then the "make install" will install<o:p></o:p> glamor.conf to your local directory rather than the two system<o:p></o:p> directories. So you may need to manually copy the file to the system's <o:p></o:p> configuration directory. Otherwise, you will encounter segfault when<o:p></o:p> start the xserver. Here is the content of the glamor.conf.<o:p></o:p><o:p> </o:p> . Section "Module"<o:p></o:p> . Load "dri2" <o:p></o:p> . Load "glamoregl"<o:p></o:p> . EndSection<o:p></o:p><o:p> </o:p>The reason why we need to load dri2/glamoregl earlier is both glx-xserver<o:p></o:p>and glamor are a dri2 loader. And glx-xserver side has a own glapi/dispatch table <o:p></o:p>implementation which is a subset of the standard mesa's implementation. So if<o:p></o:p>the glx module is loaded earlier than dri2/glamoregl, then we will get an incomplete <o:p></o:p>dispatch table and everything is broken in glamor then. This is also why we need to<o:p></o:p>add --enable-glx-tls parameters when build mesa, as we need to keep mesa align <o:p></o:p>with Xserver's behaviors, xserver will enable-glx-tls by default, but mesa will not.<o:p></o:p><o:p> </o:p>After you finish all the above steps, then you can try to start x with glamor enabled<o:p></o:p>DDX. To make sure it's the glamor running, you can refer to Xorg.0.log, and <o:p></o:p>check that the Glamor is enabled if you can find the log like:<o:p></o:p> ''__intel(0): Use GLAMOR acceleration.__''<o:p></o:p><o:p> </o:p>= Plan =<o:p></o:p><o:p> </o:p>We plan to release next version 0.5 at early of June. And the following major features will be added:<o:p></o:p> 1. Fully gradient optimization including linear and radial. Actually, <o:p></o:p> the code is already in this release, but as it has some bugs and<o:p></o:p> we disable it currently. Will fix those bug and enable it at next<o:p></o:p> release.<o:p></o:p> 2. Large pixmap support. Currently, mesa only support 8Kx8K texture<o:p></o:p> size, if a pixmap has larger size, we have to store it in main<o:p></o:p> memory and is not efficient. This feature will tile a large<o:p></o:p> pixmap to a texture array.<o:p></o:p> 3. Fully trapezoid optimization. Currently, the trapezoid rendering<o:p></o:p> is not optimized, and it will call pixman to do the rasterization<o:p></o:p> and then call glamor_composite to do the following composition,<o:p></o:p> and then many texture uploading overhead is triggered there.<o:p></o:p> 4. Fine tune the fbo cache mechanism.<o:p></o:p><o:p> </o:p>There is also a wiki page about glamor for your reference at:<o:p></o:p><a href="http://www.freedesktop.org/wiki/Software/Glamor">http://www.freedesktop.org/wiki/Software/Glamor</a><o:p></o:p>Thanks for Junyan to prepare it.<o:p></o:p><o:p> </o:p>The following changes since commit 6167738a70fce8b86190f3610da4363f11b34d5f:<o:p></o:p><o:p> </o:p> Set glamor's initial version to 0.2.0.
