Good news for OS developers and open-source driver writers: intel has released documentation (and that's documentation, not just source code!) for their integrated graphics platform!
Here's the list of chipsets covered by documentation: Quote:

You clipped the quote a bit too early - the R500 and R600 refers to AMD/ATI releasing stuff (does anybody have an URL?) but only 2D stuff (they're cleaning up patent/whatever issues before they release 3D), and obviously only for a few of their chips; notably they won't be releasing stuff for HDMI/HDCP capable cards yet, because of DRM issues.

The documentation is for "Intel® 965 Express Chipset Family and Intel® G35 Express Chipset Graphics Controller PRM". Only source code for other hardware. I do hope there is much backward compatitiblity as I have a 915GM - time will tell.

Hm, the list from their site (which I've quoted) says "915GM Mobile 915GM/GMS/910GML Express Graphics Controller", but that might be an error?

Madis731: how do you read intel manuals then? you got to get some "overview" first, and then you'll know where to look for part that interests you.

anybody know why intel make always manuals so... FAT?
is it to discourage little non commercial devellopers or what? IA manual: up to 800 page per volume needed: only 50 compressed pages. |

Intel is very thorough and all the information I need is no doubt in the documentation I have. This is far far better than Nvidia or ATI is doing currently.
Usually, it is presented from several perspectives: hardware signaling, startup software, general use, compatibility (legacy support). This creates overlap in the material covered. Since Intel produces their own boards they have a solid understanding of what is required for that process, imho. |

one page per feature. it's largelly enough.
one day, i'll prouve that, you'll see...the revenge of simplifior, the new super hero! ![]() intel developpers manual are more repetitive than anything else. for exemple, you see many times the definition of linear address space. and font is big. and the frames are large, efficient text and explanation is ~10% of the total documentation.

Quite the learning curve! I'm happy to take small bytes...

bitRAKE: so in effect, you need to read 10x the material of "just" the graphics documentation in order to understand it?
![]() I'm certain that you can get away with a lot less, though, if you're only going to focus on a subset of the graphics documentation; at least I hope so, because we need to extract "just enough" information to set modes / detect current mode... a tiny amount of accelerated 2D wouldn't hurt, either, but is not required. |

Cute
![]() HDMI doesn't necessarily imply HDCP, though, does it? And I was referring to AMD/ATI, not intel... |

That is from the ICH-6 docs - which I'm currently wading through.

@f0dder - sorry, didn't read carefully...
There's info on the older chpsets that I didn't find earlier, though they seem to be old: http://mysearch.intel.com/corporate/default.aspx?culture=en-US&q=%22display+registers%22&searchsubmit.x=0&searchsubmit.y=0 810 & 815 have nice explaining pictures in them. From the first look, 965 has less ![]() |
