I don't know about the others, but this one is because HyperZ got disabled for bugs. You can manually enable it (echo "R600_DEBUG=hyperz" >> /etc/environment) and get back to the old performance.

Special thanks to David Airlie for making OpenGL 3.3 support happen for r700 and older too

I agree with this. This is the single biggest feature.

with the new radeon.dpm, I have serious glitches with pulseaudio, since kernel 3.12 .

[Azpegath]

I'm unable to use anything after 3.12 since my Radeon crashes and the fan maxes out. I've written a bug for it and bisected it, but no cigar yet.

So, we'll see 3.14 kernel on next linux distros?

Okay, and the performance regressions found in 3.13 and 3.14 ? Have they been fixed?

Bug i complain as of 3.14-rc1 has bin fixed/reverted in 3.14-rc7, so all good for me

But why that particular combination "VM_PFNMAP + x86 PAT + write-combine" is slow here i don't know .

if kernel 3.14 is the same shit like 3.13 i will continue with 3.12, wait and see

Same here (at least until I get a Broadwell laptop)... but I want to try to backport TCP auto-corking

I want to put this kernel on a Raspberry Pi, just so I can say I'm running Pi on Pi...

Mailbox Hardware Support

I am configuring 3.14 right now and have stumbled in "Device Drivers" onto "Mailbox Hardware Support".

It is described as a special FIFO system for sending messages on board between different busses.

What is it specificallly for and which HW uses it ?

Is it meant for ordinary PC, perhaps upcoming AMD APUs with small ARM core onboard or something completely different ?

Ubuntu users can install the "official" backport:
