    Ahh, OK... so that's probably an unpublished page dragged out into the sunlight by a search engine. The bane of web developers everywhere :)

    Yeah, I didn't recognize "4 x SR" as meaning "4 single rank DIMMs" and took it to be some shorthand for a 4-rank DIMM. Remember I hadn't actually read the article.

    Don't know why 4 x SR performed...

    I haven't been involved in memory controller design for a long time, but even back in the dark ages there was a fair amount of guessing (called "prediction" these days, which sounds more scientific...

    Yeah, IIRC having >1 rank allows you to interleave accesses on a single channel. If we didn't have burst transfers that would make a huge difference (maybe 50% higher throughput) but since memory...

    How did you get to that page ? I wasn't able to navigate there, looks like it's a work-in-process page that hasn't been (or shouldn't have been :)) published yet.

    To answer your question, the...

    AFAIK dual vs single channel has a big impact on performance, while dual vs single rank has a smaller impact on performance but still makes a difference.

    Glamor has been around for a long time, just not used by the modesetting driver AFAIK (if it was supported earlier, why would Eric be adding glamor support in Oct 14 ?). I could be wrong though...

    I was under the impression that Eric's glamor + modesetting patches had not gone upstream yet, maybe I missed it...

    SW rendering is usually faster than HW acceleration for those tests IIRC... but not faster for "general use".

    I was staring at that picture thinking how unusual it was that you had put German-style power wiring (the adapters on the first page definitely look European) into a midwest house.

    Key point here IMO is that there is a big difference between "many apps will run without X" and "enough apps will run without X that X will cease to be a requirement".

    I know the idea of saying...
  14. I don't think anyone expects X to go away...

    I don't think anyone expects X to go away completely for a long time, ie it will still be important even as a layer over Wayland/Mir/whatever. Apps are still being ported *to* X every day...

    I think Veerappan's point was that the primary use of 32-bit OS on 64-bit hardware these days is at the direction of a corporate IT department, in the hope of at least slightly reducing support...

    No, as far as we can see 32-bit kernels on 64-bit hardware are going away pretty quickly. If something changes we can revisit 32-bit kernel support but no plans at this time.



    Yeah, if we do...

    Sure, not a problem. We just weren't seeing interest in writing *new* 32-bit apps/libraries built around HSA to run on 64-bit hardware.

    Again, remember that all we've done so far is disabled...

    Oh geez, political conspiracy theories already :)

    We weren't sure if there was a need for 32-bit support, but implemented it anyways so we could test it and figure out later if it was required....

    Yep... but it was the 16-bit PC AT version that was standardized as "ISA".

    You see occasional references to "8 bit ISA" for the original PC bus connectors but I don't think that was ever part of...

    This, for starters. I built a couple of these, used them to control a video special effects studio.
