AMD Radeon HD "Cayman" Finally Moves On With Acceleration
Phoronix: AMD Radeon HD "Cayman" Finally Moves On With Acceleration
It was last December that AMD had unveiled their newest "Cayman" graphics processors, which at launch powered the Radeon HD 6950 and Radeon HD 6970 graphics cards. The open-source driver support for Cayman GPUs had lagged behind the rest of the Radeon HD 6000 series "Northern Islands", but in February there was Cayman programming documentation released and in March there was then Cayman kernel mode-setting support. Only today is the AMD Cayman GPUs now getting up to speed with supporting hardware acceleration on the open-source driver stack...
this is good for all r600 and r300 users because now he do have the time to write the shader based video acceleration
and this solution should work for all r600 cards and hopefully for r300 to.
What this news talking about? What matters if we couldn't use our Graphic cards on radeon?
I have HD6850 and switched fglrx today again. Because of random GPU locks even on surfing at internet! https://bugs.freedesktop.org/show_bug.cgi?id=36542
I don't talk about huge +100W power waste if I use radeon and If I use low GPU clocks than GPU is as slow as my IGP...
So 6xxx series on -xf86-video-ati aka radeon series are too far being usable for home users.
Harping on about something like "The open-source driver support for Cayman GPUs had lagged behind the rest of the Radeon HD 6000 series " won't make unpaid developers work any faster, because they're doing it in their free time and because they want to, and it (probably) won't make paid developers work any faster, because you aren't their boss (and they're probably already working on what they can work on, at the speed that they can afford to work at, anyway)...and besides, that specific note is about something that happened in the past, and has been covered already (on this site, even).
Of course, I appreciate your work. There are often things that you write about here that I would otherwise have missed. But I think you can leave out the previous article mentions; at least, you can shorten them to something along the lines of "Things are still rocky with [so-and-so a driver], as you might already know (but if you don't, check out the archive <linky>)", right?
Anyway, nice to know that Cayman is catching up. Hopefully it'll be in good shape when I finally get my laptop. ^.^
3D acceleration also available
Phoronix has always wanted to go ten times as fast as reality. Take for example "open source parity" on the 8000 series. Yes, they're hoping that on the R8000 series the open source team will at least make it to the starting line at the same time rather than starting five miles behind, but one is still a Olympic gold medal candidate while the other has more than their hands full just to finish. If you're going to hold them to the gold medal standard, I promise you'll see nothing but disappointments.
