I can give you some information my work porting the nouveau/drm/ttm to AROS (http://www.aros.org/). AROS is AmigaOS clone and it's very very very far in terms of API and concepts from Linux kernel so I think it's a good example to talk about portability. Currently my work is only focused on 3D part, not touching the 2D part at all. Generally it took me about 1,5 months of evenings to port the current (sources from December 2009) nouvea/drm/ttm/libdrm/nouvea gallium driver to AROS (I would call it alpha version of the port though) however I have never been working with graphics or graphics drivers before. In terms of portability I would rate the modules in following order (starting from most portable) nouveau gallium 3D drivers nouveau NV0X-NV40 drm drivers libdrm nouveau "common code" (files named nouveau_XXX) drm "common code" (files named drm_XXX) nouveau NV50 drm driver ttm Basically the only module that does not seem to be specially written with portability in mind and has a lot of Linux dependencies it ttm. I implemented some of those dependencies in my AROS port (reference counting, atomics, spin locks) and disabled some others (swapping support, work queues) If you are interested in any specific topic, please let me know :) Best regards, Krzysztof _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
