    As with most/all SoC's, the video decode/encode acceleration is external to the GPU.. and in fact there seem to be two different blocks, depending on which generation of snapdragon chip.

    Linaro...

    at the moment, ifc6540 is the only option for a4xx.. quite fast, but not the cheapest arm board around

    For a3xx gpu there are...

    Not sure if that is the easiest way to figure out all the registers. It's not like you'd have comments or register bitfield #define's in decompiled code.

    In general, I don't particularlly want to...

    Some of the logic will be shared, but all the registers have shuffled around so I'll need to sort out again which bits to set in which registers for binning pass..

    Should be easier to get going...

    if they don't land in ubuntu archives, I'd guess the linaro builds for ifc6410 would pick them up

    basically yeah.. it's not all I do, ofc. I guess you can call it my "upstream-time" project

    To be a bit fair, the blob driver does have more features.. and I benefit a lot from mesa/gallium ;-)

    fyi, see http://mydragonboard.org/

    the ifc6410 is probably the one working the best w/ linux currently (freedreno / upstream-mesa works pretty well on a3xx, linaro makes regular builds for...

    if you are trying to escape the pvr graphics nightmare, then a device from imgtech is perhaps not where you should be looking ;-)

    oh, and of couse vc4 is making rapid progress, so hopefully pretty soon a sane graphics situation on r-pi

    tbh, there are a lot of options.. probably depends a bit on your price-point, etc..
    freedreno / ifc6410 (apq8064), etc
    nouveau / jetson (tegra tk1)
    intel / minnowboard max
    etnaviv / various iMX6,...

    Except intel does not have the rights to release docs about the IMG cores. Which is probably why all the intel OSTC folks would rather pretend that these parts didn't exist ;-)

    ahh, I did not realize that.. all my experience w/ pvr was sgx, not rgx..

    which, at least for linux support, intel would rather pretend didn't exist ;-)

    Since pvr does so much in the shader (including the micro-kernel / firmware, which is a big part of what makes it's architecture such a convoluted mess), it is actually a pretty useful step. ...

    fwiw, at least if you stick w/ the qcom chips which do not have an integrated modem, this is not really a concern. afaiu for external modem everyone uses some sort of high speed serial connection...

    one more qualification: opened up ISA documentation *by the vendor* ;-)

    there are at least 5 more ISA's for arm/SoC gpus that have been r/e'd (vivante + mali VS + FS + two generations of adreno)

    well, actually it can... ie. break build for other arm archs, etc

    anyways, not like 3.18 is the last kernel release ever..

    just not ready to merge in time, I think.. Dave is pushing back against merging things which are not bug fixes after -rc5 of the previous release, and new drivers should probably be ready to go...
