Hi, |
| 2 |
I've completed a round of stages suitable for SGI mips systems. |
| 3 |
|
| 4 |
They're available here: http://dev.gentoo.org/~mattst88/mips-stages/ |
| 5 |
|
| 6 |
In order to use them, you really need to have an existing Linux |
| 7 |
installation (or BSD, perhaps?) since we don't have any working |
| 8 |
netboot or CD images. (Please respond if lack of bootable media is |
| 9 |
preventing you from testing. I really need to know what the demand |
| 10 |
is.) |
| 11 |
|
| 12 |
The stages are all multilib, meaning they support o32, n32 (default), |
| 13 |
and n64 ABIs. n32 is the default ABI and it gives a rather nice |
| 14 |
speed-up over the o32 ABI previously used. With multilib, glibc must |
| 15 |
be compiled three times, so if you have no need for the o32 and n64 |
| 16 |
ABIs, you may switch profiles and on your next glibc build, they'll be |
| 17 |
removed. Once removed, it's not trivial to get them back. If you wish |
| 18 |
to switch the default ABI of your system, you should switch to another |
| 19 |
multilib profile and recompile your system. |
| 20 |
|
| 21 |
The mips3 stage is compiled with -mfix-4000 -mfix-4400 so it should be |
| 22 |
suitable for any MIPS III system using R4xxx CPUs such as the Indigo, |
| 23 |
Indy, and Indigo2. |
| 24 |
|
| 25 |
The mips4 stage is suitable for systems with R5xxx CPUs such as the Indy and O2. |
| 26 |
|
| 27 |
The mips4-r10k stage (will be uploaded in a few hours) is suitable for |
| 28 |
supported R10k systems, such as the Indigo2 and Origin 2xx (and |
| 29 |
perhaps R10k O2s?). |
| 30 |
|
| 31 |
Please test and let me know of your results. If you are unable to test |
| 32 |
due to lack of boot media, please tell me what kind of systems you'd |
| 33 |
like boot media to be made for. |
| 34 |
|
| 35 |
Thanks! |

PS: there are a rapidly diminishing number of bugs that prevent MIPS |
| 39 |
stages from being built without modifying the portage tree. They are |
| 40 |
listed here: |

https://bugs.gentoo.org/show_bug.cgi?id=358149 |
| 44 |
https://bugs.gentoo.org/show_bug.cgi?id=373361 (for r10k stages) |
| 45 |

If you'd like to help offset the cost of electricity used to create |
| 47 |
these and future stages, please send me a private email. :) |
