Is it possible to have a USE flag as unichrome which will add support of Unichomre drivers in X, kernel (drm), and possibly Mplayer. There is a unichrome USE flag already available but it works only for MythTV. 1. If it is possible, having unichrome as a USE flag should patch the kernel (?) to make DRM available only as a module and not as a part of the monolithic kernel. (I know this is very impossible since different flavors of kernel would require different patches, but this could be done only for gentoo-sources) 2. X should be compiled, and then via directory should be replaced with unichrome directory and so do other steps.... 3. Unichrome - 3D drivers should be copied. 4. MPlayer should be patched with http://sourceforge.net/project/showfiles.php?group_id=102048&package_id=130199 Unichrome documentation Link: http://sourceforge.net/docman/display_doc.php?docid=26963&group_id=102048 There are more patchsets in the Files section of Unichrome.sourcefirge.net. But only above mentioned should be enough to start with. This will bring down the unichrome-driver installation to only setting Xorg.conf Reproducible: Always Steps to Reproduce: 1. 2. 3.
Created attachment 61618 [details] xorg-unichrome-6.8.2-r1.ebuild Check this out, it is modified ebuild based on original xorg-x11-6.8.2-r1, that adds support for getting opensource unichrome drivers ( http://unichrome.sourceforge.net/ ) from cvs. just put it into your PORT_OVERLAY and pass USE="unichrome libviaxvmc unichrome-cvs" as use options. The CVS version is needed on my laptop (Actina) based on km400 chipset. The unichrome-X-r30 displays only black screen. This ebuild is just for user conviniance. I will submit another ebuild for possible inclusion in portage.

Just a "me too" here. I will try this ebuild tonight and give feedback when I have time to test it. In general, please push these patches forward -- they are of great use to many people.
quick update: the above ebuild worked fine, except that it did not seem to provide unichroms_dri.so, for direct rendering support. In my mind, this is the whole point. I found this other ebuild which appears to provide DRI support quite nicely (to wit, 500 fps in glxgears versus 150 in the previous case): http://boom.kalf.org/epia/xorg-x11-6.8.2-r3002.ebuild obviosuly, it's too early for claims of stability, but no catastrophic failures yet.
My addition: (having VIA/S3 Unichrome KN400) while using 2.6.x-gentoo-x I have to DISABLE kernel-side DRM driver (nor built-in neither module). Well, in fact it may be build as a module but has to be replaced with one provided by unichrome anyway. In reply to #4 - pkg_postinstall() - print_info should be printed only if unichrome flag is presenf, not always, consider replacing via directory in do_patch function and unpack patches at right places - unpack_all() :) I know those are details but let's stick to ebuild's ordering of world Anyway: thanks for those ebuilds - all of you
Since the advent of new modular Xorg 7, the feature for driver request has become quite simple. There is already VIDEO_CARDS="via" option. So, we can just have another VIDEO_CARDS="unichrome" which will pull the unichrome code from their Git repository and install it just the way other drivers are installed. Btw, is there a chance/idea that the current unichrome code will be committed to original branch of Xorg as a replacement of current via?
