You smart guy... Bobcat is 5xxx GPU also, and it needed AMDs attention to get it working, so will be Liano. The pci ids will be added at least, but that work will be headed towards 2.6.40 in the september maybe. So no out of the box experience for Liano.

r800 vs bobcat is a difference they need to dev some stuff.
but there is no difference between bobcat and Liano on the driver side.
and yes adding an PCI ID is really a hard work
Yes, pci ids are piece of cake, but they will come to 2.6.40. 3 months after the HW starts shipping. I really hope AMD will do some Liano commits along with Caymans.

i also seem to remember that S3TC has been implemented (fully or partially i don't know) in an external library or something

Yes, Liano is a nice piece of silicon(at least on paper), and I am waiting it for my next build.
AMD are talking about Cayman for the next merge window, and not a word about Liano. That is why I hope Bridgman shows up, to clarify the situation.
S3TC is implemented by external library onli for r300g, but not for r600g.

And about S3TC, it seems to exist 3 open source implementations: libsquish, imageLib and libtxc_dxtn..
I didn't know about other S3TC projects. Thanks a lot.
The way I imagined things, is that the game textures are already compressed with S3TC, and have to be fed to GPU without any further compression/decompression. Can someone clarify this.

Llano work was started at the same time as Ontario, and we believe the code changes should be similar although not quite the same. We were able to get Ontario hardware into agd5f's hands first because the products are on significantly different launch schedules. I expect open source driver support for Llano will come out at roughly the same time relative to launch as Ontario did, but we'll know more in a couple of weeks.
As someone else already posted, the support for Ontario and Llano primarily involves changes to things like memory controller setup while Cayman has an entirely new shader core so there's a lot more work required there.Test signature
