    meh, if they claim that, it is at least partly BS ;-)

    If nothing else, most drivers are going to want to do some cleanup optimization after converting from vec4 to scalar operations..
  2. pretty close except spir-v and tgsi are not...

    pretty close except spir-v and tgsi are not really so good for moving stuff around. They are more like serializable formats defined as part of an api/abi, for exchanging shaders. NIR (or LLVM for...

    not to mention MRT support which Ilia also pushed recently.. we are getting tantalizingly close to gl3 :-)



    someone needs to post some screenshots of blob vs freedreno dolphin renders :-P
  4. Don't forget sb (r600, if you aren't using llvm),...

    Don't forget sb (r600, if you aren't using llvm), codegen (nouveau), ir3 (freedreno), qir (vc4) used in the backend of the compiler.. :-P

    But seriously, there are different IR's that serve...
  5. I don't know if I'd say that "mesa" and "intel"...

    I don't know if I'd say that "mesa" and "intel" are currently competing.. but for sure, NIR will allow for some re-use of compiler passes between intel classic mesa driver an other gallium drivers...
  6. I do not believe so.. if someone actually had the...

    I do not believe so.. if someone actually had the blob intel android driver and ran strings on it, that could be pretty easily confirmed. But I think they are shipping a blob driver (presumably)...

    there is a thread on freedreno list:

    http://lists.freedesktop.org/archives/freedreno/2015-March/000237.html

    (one of those msgs has link to GSoC proposal)

    yeah, looking at gl_vendor strings from intel android devices, I come to the same sad conclusion.. :-(

    *blink*

    Umm, I get that you are trying to play devil's advocate here, but this is kind of nonsense. I know you are smarter than that. Userspace components end up having dependency on which libc...

    tbh, having not seen the vulkan spec yet, it is a bit premature to speculate on the path towards vulkan.. although I expect there is room to share a spirv->nir pass, but the compiler is not...
  11. I don't think you will really see SPIR->SPIR...

    I don't think you will really see SPIR->SPIR optimization passes (or TGSI->TGSI for that matter).. drivers will convert into NIR (or LLVM) which is easier to manipulate for optimization passes..

    fwiw, the bootloader is open source.. I suspect what you are thinking of is the rpm (resource power manager) firmware.

    Anyways, at the end of the day, who wins the 'most open' prize depends on...
  13. I'm not excusing android devices that ship with...

    where exactly is canonical failing here?
    are you aware that with android phones its the same issue. since mediatek is the one not giving out proper sources. the OS itself is set up properly, its...
  14. yeah, I have no doubt the source of the mess is...

    yeah, I have no doubt the source of the mess is the SoC vendor.. but really canonical should have a clue about this sort of thing and put their foot down before the phone shipped. I see no problem...

    yup, it's basically the chromium gpu process running on bare metal.



    basically in the CrOS architecture, since they have the dedicated gpu process which runs fullscreen, there was no need for...
  16. Earlier versions of spir were, and they may...

    Earlier versions of spir were, and they may possibly still use llvm for the glsl -> spir-v compiler that they mentioned (I haven't seen the src code for that yet, not sure if it exists anywhere...
  17. To some degree, different ir's with different...

    To some degree, different ir's with different purposes. Spir-v would get translated into nir or llvm anyways, and then potentially some different more driver specific form before finally popping out...
  18. different definition of state.. in this...

    different definition of state..

    in this context, "state" means "stateful API", ie. w/ opengl the driver is tracking state behind the scenes rather than application passing objects that describe...
  19. One way or another, I don't think supporting both...

    One way or another, I don't think supporting both a gallium pipe driver for opengl, and a vulkan driver, is a reasonable option. It's not like opengl is going away tomorrow. Unless someone steps up...

    I had high hopes for android devices with intel graphics, but somehow intel seems to be pushing their closed src driver on android. Take a look at the gl vendor strings:
