We need all help we can gather for this to be done. If you have any knowledge about what makes apple graphics tick, or about kext patching, or about C/C++/Cocoa/Assembly/Hex editing, join us!
Even if you're not particularly skilled in any of these fields, but are willing to help somehow, you're welcome!
(sorry if this post looks like armed forces enlistment propaganda, lol!)
A little review of the current situation to help the newcomers to this thread (and arches, noobun2, meklort, firemansam and anyone involved can correct any wrong info if they please):
1) GMA 3150 isn't supported by apple, so we couldn't achieve full graphics acceleration yet. However, you can get native resolution (in most cases, 1024 x 600) even with no kext loaded. But, as said, no qe/ci: certain programs, like iMovie, won't work. Certain features, like time machine, will be in the better prospect buggy and unreliable. Youtube movies are a no go;
2) Even without full support, some people can get the GMA 950 kext to load with some editing (i'm not sure what must be edited though). But this will result in extreme slowness of the system, and the boot time will exceed 30 min., at least in older iterations of osx (arches, if i understand correctly, have a boot time of circa 2 min. with mountain lion, however without any hardware acceleration, unlike lion, even with the kext actually loading). Since GMA950 (which has native qe/ci) and GMA3150 are somewhat related, the GMA 950 kext is our current target for getting (hopefully) qe/ci for GMA3150 someday, at least in Lion (and hopefully in Mountain Lion someday, if we somehow patch the GMA950 to give acceleration in 10.8);
3) It's possible to use the gma 950 ketx framebuffer to attain a certain degree of graphics acceleration (again, how to do it, and how much graphics acceleration can be achieve, this will be for arches to say to us). As i understand, with the framebuffer, some simple (but crucial for a reasonable user experience) graphics tasks can be done, like watching youtube movies. However, as the sweet always come with the sour, when using the framebuffer, the cursor gets corrupted, which is pretty annoying. Meklort developed a solution for it in snow leo, but it does not work in mountain lion, and as far as i know was not tested in lion.
That's the current situation. Anyone who wish to contribute to this adventurous task, be welcome! I recommend to spread this thread in every osx86 forum. Maybe this holds the attention of more capable people to unite eforts with us.
Our primary material for this job:
AppleIntelGMA950.kext.zip 142.22K
84 downloads: The unpatched GMA950 kext;2009 Q4 Drivers: Intel Linux Graphics: 2009Q4
2010 Q1 Drivers: Intel Linux Graphics: 2010Q1: The first one is the last intellinux915 before Linux support for GMA3150, the second is the intellinux with GMA3150 support. The codes could offer hints at the patches that should be made, and even the possibility of a full port.
Getting closer to figuring out what (and what not) to do to integrate KDP support for it though, and the knowledge spills over into the graphics driver issue since the OSX driver model follows some conventions I didn't expect.
