 |
|
dear community,
does anyone of you have tips for installing gentoo on a sandy bridge architecture? if someone has already installed gentoo on such a setup, it would be helpful to have information about it. like what cflags you used, or if special kernel configs are needed to run the system properly. i will post my progress (hopefully) here too.
kind regards,
onelove |

@onelove
also im prinzip musst du nur die Grafik im kernel wie bei vorherigen Intel Grafik"karten" aktivieren, ansonsten sind da keine weitere einstellungen nötig, da diese ja der system agent aka frühere uncore alles andere reguliert

@selberbauer
i finished the physical construction process this night. now i am typing from work. i immediatly started to boot from 11.01.2011-livecd iso, but it didnt work - it stopped right after decompressing the iso and before loading the kernel. ubuntu 10.10 i386 worked. so i think i will install from within ubuntu-live.

€1: i dont need the built-in graphics. i will use discrete graphics. btw, is there an option to deactivate the cpu-internal graphics? i dont find anything like that on my efi-bios for a p8p67 pro. |

My understanding is that the P67 chipset only supports external graphics, so it would make sense that the bios wouldn't have any options for the internal graphics. My Sandy Bridge system has the H67 chipset, which supports both internal and external graphics, and the bios does have options for that.
On the install question: I didn't do a fresh install; I just upgraded CPU/RAM/mobo and booted from existing Gentoo install on the HD. This worked OK, though I'm still tweaking the kernel to get various hardware working, and I haven't been able to get X working at all on the CPU-native graphics, so if anyone has hints on that I'd appreciate it.

@TiccTech:
thx. regarding your question:
i just found this source. perhaps it helps you further on:
http://www.phoronix.com/scan.php?page=article&item=intel_sandy_breaks&num=1
but since i don't use the internal graphics, i don't know any more. sry  .

lspci -vv
with lspci version 1.3.7. perhaps it helps someone. ignore the nvidia chip an the emu10k1 chip. the rest is from a p8p67 pro mobo, serving as the sandy brigde platform.

You need kernel 2.6.37, mesa 7.10 and xf86-video-intel 2.14 for the internal graphics. |

FWIW, Sandy Bridge i5-2400 working here very well, including the GPU (which blows away my last desktop's Radeon for 2D, VA-API, and 3D).
Keyworded packages:
=media-libs/mesa-7.10*
=x11-drivers/xf86-video-intel-2.14*
=sys-kernel/git-sources-2.6.38*
=sys-kernel/gentoo-sources-2.6.37*
=x11-libs/libva-1.0.7*
=x11-libs/libdrm-2.4.23*
I think we need GCC 4.6 before we get real CPU optimizations? I'm using -march=core2 for now. |

Thanks Gusar, Luke-Jr!
X on CPU-native is working pretty well for me now, though I couldn't find any libva beyond version 0.31.
I had some problems with -march=native; I'm currently recompiling with no -march at all, to be conservative.

@TiccTech,
problems with -match=native is not good. i did compile with -march=native and had no problems at all. what kind of problems you have?

| -march=native only makes sense when GCC knows your CPU, which it won't for SB until 4.6 |

It's possible, I suppose... But at least -mtune requires more intimate CPU knowledge that can be autodetected. |

Hi,
last night i was installing fresh gentoo on: i3 2100T, because i want use the internal GPU...

And i ask was mean "Keyworded packages" i'm new in gentoo (i'm debian squeeze, but think better support for sandy bridge in gentoo)...
I follow steps of hand book... only emerge this packect get support for sandy bridge (i3 2100T?)
Thanks! |

@josejuan.montiel,
Welcome to Gentoo. The concept of keywording is explained in the Handbook, Chapter 3: Mixing Software Branches.

I just wanted to add to that... when I re-setup last week and used the -march=native, I got with several packages and programs illegal instructions which ended up in a non useable system (e.g. tar wouldn't work).
At the moment I use -march=core2, which works fine for me.
It was for me impossible to build a system with -march=native using the 060911 stage3 on my i7 Q2820 laptop.

Hi,
first, thanks for your answer, This help me to understant, how to use latest kerlnet "marked with ~" to try fully support to "sandy bride".
This is similar to "apt pinning" in debian  now i understand...
But, the reason to continue this thread was my interest in get full support for graphics in i3 2100T chip...
Maybe, the better approx was open a new thread... |
