    There's a serious inability on your part to participate in a reasonable discussion. I probably shouldn't bother responding, but I'll do it only once more given the lack of meaningful response.

    LOL there is no real GLSL compiler. you can rewrite this sad piece .
    the status for the GLSL compilers for the r600 are "Sad" and yes maybe we will never get a good VLIW compiler. this means its a death horse.
    The GLSL compiler, you know, the one that Intel wrote? http://cgit.freedesktop.org/mesa/mesa/tree/src/glsl

    It's C++.

    You're incorrectly thinking about the piece of r600g that translates some IR to hardware instructions.

    you miss an important step in your argument why should this be a no go?

    or do i have to ask linus ? LOL
    I can't tell if that's a particularly sad attempt to dodge a very real difficulty of moving user space code into the kernel, or if you actually don't understand.

    I'll assume it's the latter and waste a bit more of my time explaining it to you.

    From the kernel documentation (http://git.kernel.org/?p=linux/kerne...g.tmpl;hb=HEAD)

    Code:
    No floating point or MMX
          The FPU context is not saved; even in user
          context the FPU state probably won't
          correspond with the current process: you would mess with some
          user process' FPU state.  If you really want
          to do this, you would have to explicitly save/restore the full
          FPU state (and avoid context switches).  It
          is generally a bad idea; use fixed point arithmetic first.

    I think what you're suggesting is to move all of the 3D stack into the kernel. This would include the GLSL compiler and a lot of other core-Mesa components. The GLSL compiler, for instance, is C++ which is a no-go for the kernel. Then there's that you can't do floating-point operations in the kernel, which are obviously quite important for OpenGL.

    Also there's the issue of security -- moving thousands of lines of code into kernel space...

    20 years ago the kernel source was so much smaller maybe we should use a time travelling engine to go back in time to be sure the kernel source is smaller...

    this is just bullshit!

    and hey don't write code this makes the kernel source bigger ans we all know this is "bad" LOL

    Bridgman bullshit logic at work..

    I figured out how to make radeon better than catalyst: every time quaridarium writes some bullshit, instead of wasting your time replying you should write a couples of lines of code. At such a pace I'm pretty sure radeon will double catalyst's performance in no more than a month.

    this only sounds funny if you use analogies like "Pickup" and "Pocket"

    if you don't use analogies if you use "Bit" it just doesn’t mater the PLACE of the bits doesn’t matter because they are there anyway!

    in other words you just use rhetorical tricks to don't admit my argument.

    invalid argument because the bits are there anyway! its just a question in how to manage the bits.
    after this "Fix" the linux kernel is 10x larger really who cares? no one cares !
    the bit size of the kernel source doesn't care!
    the bits are in the system anyway!
    you save ZERO!

    invalid argument because no one CARE! the garbage catalyst can never be in the "Linux" kernel because of this its senseless to arguing on this shit.

    why? i would not bet on this! just ask linus torvald for example!

    if he say no then its no.. but your speculations is just FUD!

    LOL... APIs can always be translates per layer.

    you can also work to get a long time run.

    over long time this is the best way to fix the linux fragmentation.

    I'm sure if bridgman wasn't in the way all the time, r600g would be in a much better state. I wish this kid would just go away..

Android is growing in popularity, and is interesting to the embedded market as well as more obvious markets like tablets and smartphones, but the graphics stack is quite different from desktop Linux so the obvious question for you is "if we spend additional money on Android does that count as spending more on Linux even if there is no direct benefit for consumer PC Linux users ?".
    you can have both in the same round if you do it right. linux-Desktop and android share the "Kernel" this means you only need to push the graphic driver into the kernel!

    problem fixed.

    in fact andorid is a "Linux" and if the drivers ARE in the KERNEL then it doesn?t matter andorid or ubuntu.
