    Phoronix: AMD Radeon Graphics Performance With The Linux 3.19 Kernel

    With the Linux 3.19 kernel stabilizing nicely, here's a first look at the open-source AMD Radeon graphics performance using this new kernel that will be officially released in the weeks ahead. The Linux 3.18 kernel was compared to the latest Git code of Linux 3.19 for several different AMD Radeon HD series and Rx 200 series graphics cards.

    hi Michael, padoka ppa maintainer here (https://launchpad.net/~paulo-miguel-...e/ubuntu/mesa/)

    If you find interesting, i fixed the opencl packages in my ppa, they are kinda broken with oibafs, missing amd64 build and amdgcn support (oibafs only provides r600).

    Anyway, AMD clover/opencl is working in my PPA, so feel free to fire opencl 1.1 benchmarks at will.

    I would like to seize the opportunity to reiterate that has of now, my ppa is less and less a derivative of oibafs, since ive been deviating from his work and adding more cutting edge stuff to mine (LLVM 3.6, clover/opencl with amdgcn support, intel experimental modules (rendernode,create2,async-swap, dri3 is off for now), and a few well tested apps (cmplayer, transmageddon). we all stand on the shoulders of giants (oibaf)

    regards

        Tom published perf-Jan-08-2015 llvm branch yesterday, include both spilling and perf improvments...

        This should be first one where rendering is correct in phoronix tesseract benchmark (because of mid GI used) (fglrx vs radeon should give correct fps numbers in comparison now i guess, etc...) and performance are never better there of course unigine demos and other apps are all faster .

        edit: actually my bad, some mesa fixes are also needed to see that all... i forget what i had tested

          is it the llvm master svn yet? do you know the svn commit number ? if it is already i might build llvm 3.6 today.

            Thanks Michael, this means you will finally start using LLVM git.

              This is fucking interesting. Please benchmark ASAP. If I wasn't so much busy this month I would have done it myself.

                He already did, take a look at the first page of the article (the table with the versions, see the mesa version? it says (padoka ppa), guess which ppa it is? he has been using my ppa for some time now, he even acknowledged that in a previous article. i was just pointing out to him my latest opencl work that wouldnt be immediately obvious just from a package update.

                    just saw the commits, they are 48 hours old, should be in mesa master soon. once they hit, my mesa compilation will kick in. at least llvm will be ready (compiling it now).
