    I'm not booing him, i'm just saying that he probably throws in an anti-AMD rant in over 50% of the things he writes. It's not exactly shocking to therefore see him claim that these guys are better than AMD. It'd kind of be shocking to see the reverse, actually.

But I think it's a fairly distant relative of the binary-blob code shipped on Raspberry Pi, and even more distant to the code that shipped on the more recent S II Plus / Grand, so it seems likely to be similarly challenging to port to any of those platforms. (And Samsung already announced Android 4.4 support for Galaxy Grand, so there's less motivation to port to that.)
    That's good to know. Challenging doesn't mean impossible, and this could help in the future, for both new Android versions and alternative OSs.

    It's the same GPU that's used in the latest SoCs Broadcom has released, which are still being developed and shipped in new products. It's a few years old and not high-end any more, but it still seems to be competitive at the middler/lower end of the performance/power/cost scale, so it's certainly not dead yet.

I looked over the Wikipedia list on what products use VideoCore and their xda-developers pages, and the drivers are certainly making a difference for the Galaxy Y/Ace i crowd, as those fairly old smartphones are now getting an update to a relatively new version of Android. The more interesting hardware, though, is Galaxy S II Plus and Galaxy Grand, and I can't see much information on whether the docs help there.

I also found this... http://www.broadcom.com/docs/support...IV-AG100-R.pdf which looks like acutal documentation of the general architecture... pretty interesting although I don't know what percentage of the device it acutally covers. I doubt it covers setting up the chip and such... even so.
    Hey, AMD cards still use proprietary init firmware. From my understanding, these videocore drivers are documented enough not to require any such proprietary nonsense.

    Note, though, that almost all Broadcom NICs still require proprietary firmware - and as a company they barely participate in any FOSS at all, their foss bcm driver is really new and barely supports any chipsets. Most of their stuff barely works under their proprietary wl driver.

    Well, look who it's coming from. He probably would rank NVidia higher than AMD judging by the personal history he always brings up when discussing AMD.

    Most of the current mobile and discrete GPU tech is a dead-end in 3-5 years anyhow so I fail to see the relevance ( https://www.youtube.com/watch?v=xsFure2h17A ).
