Hi, you must be new here. This is Phoronix, where no article has any relevant external links, only links that link back to Phoronix, just as nature intended.

Go team AMD!

"This latest round takes care of hangs with DPM on some RV6xx series (Radeon HD 3000) graphics processors and separately fixes suspend-and-resume when using UVD video decoding. "

This was actually bothering me quite a lot on my HTPC. Glad its fixed!

Which app do you use for HTPC? Guys in XBMC forum say VDPAU implementation it is not yet fully implemented within OS driver. Is there other that does it better or goes around missing stuff? When radeon driver for XBMC about month or so ago I still experienced few XBMC crashes not related to DPM at all.

In case of my HTPC, there is no need for UVD at all. Its processor is powerful enough to handle it without acceleration. It does need DPM so it would run cooler, though.

That is funny, because the same logic could be used to say "mplayer's VDPAU works just fine, so XBMC must be broken".

So basically DPM isn't done and isn't stable. So enabling it would be a bad idea. So why the encouragement to enable it, when the 3.11 kernel isn't even released? It seems a bit irresponsible. Truth is, like with any other technology, it will take a while before it's actually good enough to be used by the masses. Hanging because of bad GPU drivers destroys Linux reputation.

It's disabled by default. You should know that you're a tester when you enable it.

Anyway, didn't you rage quit phoronix?

Heh you beat me to it... But yeah, test feedback is one of the main reasons to encourage enabling DPM in its current sate. I doubt "the masses" tinker with the boot arguments anyway.

Jumped the shark with your trolling...
