    Phoronix: AMD A10-7850K Kaveri: The Linux Introduction

    This morning AMD is releasing the first APUs in their Kaveri family, their most advanced APU ever with up to 12 compute cores and is a big push forward with their overall HSA architecture. We managed to get our hands on a Kaveri system with A10-7850K APU and in the days/weeks ahead there will be many Linux benchmarks looking at the next-generation AMD APU. Here's what Linux users need to know right now about AMD Kaveri APU Linux support.

    What I don't get is how new chipsets / processors have support in the kernel often months in advance and will run out of the box on even outdated LTS Ubuntu releases or CentOS, but gpus (in general, Intel does this with their new stuff too, cutting it too close to the last minute) don't see drivers until usually after their release, especially Mesa ones, and definitely not in advance enough to guarantee even the latest Ubuntu / Suse / Fedora / etc releases work with them.

    It is hard to pitch Linux to an average Joe if, knowing they have to install the OS manually anyway unless they go through system76, they also have to make sure the computer isn't "too new".

      Kaveri is cool and all, but I'm more interested in the driver. Hopefully a link surfaces in the near future for it

        usually i am not that picky with article names... but shouldn't it be "Ubuntu introduction"? Just to be fair about Fedora, Arch, Gentoo, and the others...

          As always with AMD new hardware (in this case very good hardware especially A8 7600) lack of support, only have wait for privative drivers official release

          And on opensource side, support can be take much time if Radeon HD6xxx (VLIW4 and before) have today good state on comatibility and performance and for stay in actual state take much time (developers have working in this driver minimum 2 years before AMD free more information than 2013) but with opensorce efforts maybe solve performance issues

          if situation happend with VLIW4 hardware (much older hardware and more work on them), for GCN opensource support can have same level of mature of VLIW4 opensurce driver take minimum 1 or 2 years

          Only option for now is privative driver for kaveri hardware

            The information shared in this article holds pretty much true amongst all Linux distributions.... Especially with Ubuntu 14.04 using Linux 3.13 + Mesa 10.0.1 (and then tested on Git) and still not working right there, so you'll be hard-pressed to find it working on something older in a stable release of any distro.

              I've seen some reviews. Kaveri (except OpenCL) is not that big step forward for APUs and in Linux there are (and will be) definitely problems with drivers. So for a Linux user 6800K is the best APU s/he can get.

              Works good with latest FOSS drivers and usually the fglrx Ubuntu recommends is stable.

                AMD sending a review sample? Looks like hell continues to get periodically frozen as of late.

                  Great I'm looking forward for some benchmarks.
                  Maybe we can get a real APU test soon Haswell vs Kaveri on linux (cpu and integrated gpu)
                  I like that AMD sent some hardware to phoronix.

                    NICE!!

                    I can't wait to buy one of these and then start to experiment with the JDK 8 and HSA enabled stuff. This is going to loads of fun. Thanks AMD!

                      I guess now we find out if Steamroller could possibly have posed a threat to Haswell as a pure CPU/no integrated graphics.

                        Yeah, with half baked test sites saying things like gimp score 132123123 <-- random pointless numbers with no mention of methodology or handbrake score @!#!@#123 whatever the hell that crap is....


                        Anyhow yeah, not much of a step forward in CPU compute but holy crap that A8 7600 @ 45w ~100US is a monster. That's the way to take it I guess, is they're trying to get better PPW, looks like they're doing okay with that.


                        As for the driver situation, yeah that bites, I expected they'd learned their lesson... GDT!

                        Not sure about the pricing though... 7800 is only 1 dollar less than the unlocked 7850 ? I mean... really?

                          Oh and when you do get the system running Michael, you have to let us know about the "true audio" part. Make sure it even can play sounds and all.

                          I can't laugh enough, these guys benching these things against I7's ;p... cause you know the ~200 difference means like nothing.

                            What interests me is how easier this will be in terms of memory optimization. IIRC one of the main problems with Radeon catching up to catalyst is the memory management. In theory, with HUMA now memory management is vastly simpler, so performance could catch up to fgrlx...

                              I guess there are lots of people still hoping that some day AMD will release another Thunderbird.
