i somehow get lost in what are the priorities for open source
it can have application in PCI cell cards for computations (or whatever) but that kind of hardware is somehow targeted to a very small part of the market
(except if someone is paying them as i suspect)
one reason for a cell driver is that the onboard nvidia chip is locked down when running Linux on the PS3 so one of the SPUs can be sacrificed for some 3d accel
again not many people use their PS3 as regular PCs
its pointless (flash sucks and you cannot browse your favorite porn site)
after the post about the SpursEngine i thought they might want to do something with TVs and stuff but a TV its not the place for computations...
once AMD finishes the work with classic mesa they will be able to port the code in gallium quite quickly (i think bridgman made a comment about it in the past)
It would really be bad if Intel didn't at least have long term plans for Gallium use, considering there's already basic drivers available.
Oh well, time will tell...
Work will continue on the classic Mesa implementation even after the initial bug-fixing is done, including getting it running over KMS/GEM/TTM, and we will probably use the classic mesa implementation as a base for extending the shader compiler, but the bug fixing is the only reason for not starting Gallium3D 6xx/7xx work now.
I just hate porting code to a new platform unless it works properly on the current platform. We didn't really have a choice in the case of radeon-rewrite, but porting is *much* easier if you start with something that's already working the way you want

every time i hear this i get excited and cant wait xD
i know i sound impatient, but how long will a basic gallium port take. (i feel like im asking you this question every time you answer one of mine ^^), since mostawesomedude has been working on the r300-500 code for ages. ( i know he is not a fulltime developer and you have more manpower )
We'll have a better idea once the 3xx-5xx Gallium3D driver is further along.
Cooper is starting to come up to speed on the r300g driver and will help there; the "plan" is still that 6xx/7xx classic mesa, 3xx-5xx Gallium3D and 6xx/7xx KMS/GEM/TTM/DRI2 will all finish off at roughly the same time. All of them seem to be pretty close now; between MostAwesomeDude's work and nha porting the shader compiler across I have to think that most of the heavy lifting for the 3xx-5xx Gallium3D driver has been done.
Once those three are all working, we can tell you roughly how long it will take for the 6xx/7xx Gallium3D driver
