 Posted: Tue Jan 31, 2006 9:26 pm Post subject: Installing 2.6 kernel on sun4u architecture with 2005.1 CD |
 |
|
In step 6b on install guide, it talks about profile to select. In case of Sparc64 arcitecture:
1. Can i select a 2.6 kerenel profile (btw, is there one even available for sparc64)?
2. Will i have to use ~sparc and/or unstable USE variables to get 2.6 kernel install on Sparc64 (sun4u)?
3. Do i have to specifu -m64 variable to forces 64-bit compilation of kernel?
4. At emerege, will i have to specify gentoo-sources (will that kernel even work on Sparc64...)?
Thanks for every help.
PS. I had tried 2005.1 handbook and could find any way to install 2.6 kernel b/c i selected sparc-sources (per instructions). |

| I too am looking to do this, however, I don't believe 2.6 is fully ready for SPARC yet. Hopefully someone closer to the situation can comment. |

2.6 kernels aren't quite ironed out yet, it mostly boils down to which machine model you have and what you wanna do.
The biggest sticking points are serial support - it's sometimes problematic on some machines, and stability, lately it seems only U1/2 (sbus) machines are affected.

A power outage took it down 3 months ago. Apart from that, it used to serve my personal site before I moved it to a colo facility and it never failed me.
I'm no Sparc monkey, though  |

Thanks for the information guys.....
If one wanted this, is it just a matter of umasking a few ebuilds or is it more complicated than that?
Is it better just to wait for 2006.1? |

It basically boils down to package.keywording gentoo-sources (preferred over vanilla-sources).
If you wanna enjoy the extras you can switch to the 2006.0 profile but that involves re-emerging -e world for the new toolchain to be clean and you won't be able to boot a 2.4 kernel any longer. If you want the 2.4 fallback option use 2006.0/2.4 - but that won't allow for the new toys, just the new toolchain.

I tried to follow your notes:
1. After CHroot, emerge sync
2. chnage the profile to 2006.0 and keyworded ~sparc
3. emerge -e world
------------------------------------------------
during this emerge i get following error:
>>> Unpacking source...
* Checking gcc for __thread support ... yes
* Checking kernel version (>=2.6.6) ... no
* You need a kernel of at least version 2.6.6
* for NPTL support!
!!! ERROR: sys-libs/glibc-2.3.5-r3 failed.
!!! Function check_nptl_support, Line 726, Exitcode 0
!!! Kernel version too low!
--------------------------------------------------------------
I am using 2005.1 CD. Can you suggest any way out.... thanks. |

| Emerge glibc without the nptl use flag enabled for now. Once you are booted with a 2.6 kernel, you can re-enable it. |
