My first work is here: http://pub.haikufire.com/mesa/haiku-mesa-patch1.5.diff This gets glsl, mapi/glapi, mesa, glu compiling with very few changes in Mesa At this point I don't think using DRI2 is do-able as it is very Linux oriented, however I think we may be able to get things working (software at least for now) by using our own external GLView within http://cgit.haiku-os.org/haiku/tree/src/kits/opengl which simply links to some key Mesa libraries. -- Alex ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev

Does this involve restoring any legacy drivers that were removed a few weeks ago? Could you move to Gallium-based drivers? We are mostly looking for Radeon HD and Intel at the moment (because they represent the newest chipsets we support at the moment) It does not involve restoring the legacy drivers. We want to make sure we support do things correctly to minimize Mesa impact / work, while keeping to the Haiku (aka BeOS) method of graphic driver design as much as possible. Example, in order from top to bottom: Kernel space graphic driver http://cgit.haiku-os.org/haiku/tree/src/add-ons/kernel/drivers/graphics/radeon_hd User space graphic accelerant that maps graphic driver memory http://cgit.haiku-os.org/haiku/tree/src/add-ons/accelerants/radeon_hd User space OpenGL / 3d render that ties back to the accelerant http://cgit.haiku-os.org/haiku/tree/src/add-ons/opengl We can work on getting something working prior to providing patches, I mostly wanted to test the waters to see how the Mesa developers felt before putting the work in :) Thanks! -- Alex ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev

[Mesa-dev] Willing to take Haiku support Patches? (Was: DEATH to old drivers!)
Good afternoon! The Haiku OS project (not-for-profit organization, founded in 2001) has found ourselves in a weird spot, we have a working Mesa software render library based on a *heavily* modified Mesa 7.4.4. http://cgit.haiku-os.org/haiku/tree/src/libs/mesa However as you can imagine, updating that is going to be a *big* pain point. As Haiku is looking to get some basic 3D rendering going on it's cards, we need to do upgrade to a newer version of Mesa. If we produced well thought out Haiku OS support patches, would Mesa as a project be interested in accepting them upstream? I think a better direction may be to move away from the heavily custom integrated mesa library and move to stock version. These patches would likely start as run-of-the-mill #ifdef __HAIKU__ macros.
