Hi List! |
| 2 |
|
| 3 |
The first Gentoo/FreeBSD/Sparc64 stage [1] is ready for testing! |
| 4 |
There are a few rough edges, namely you have to compile all kernel stuff you |
| 5 |
need into the kernel as loading modules causes a kernel panic. This is |
| 6 |
probably a gcc related error as upstream uses gcc-3.4.x by default. |
| 7 |
|
| 8 |
Installation requires downloading the FreeBSD Sparc64 installation CD. From |
| 9 |
there you can choose the fixit options to get to a shell where you can |
| 10 |
partition your disk and follow the usual instructions [2] for stage |
| 11 |
extraction and system building. |
| 12 |
|
| 13 |
NOTES |
| 14 |
All modules have to be built into the kernel - kldload causes kernel panics |
| 15 |
about memory not aligned. I'm pretty sure this is gcc-4 related as my kernel |
| 16 |
patch doesn't touch module loading code. |
| 17 |
|
| 18 |
You can only boot from ad0. You can probably boot from ad1, but I only have |
| 19 |
the one disk so I cannot say for certain. I'm 99% sure you cannot boot from a |
| 20 |
specific slice / partition as sparc does not seem too support that. |
| 21 |
|
| 22 |
Only gcc-4.1 is supported - anything lower will not work for building a |
| 23 |
kernel. This is because older versions do not correctly define __arch64__ |
| 24 |
when compiling 64-bit code. |
| 25 |
|
| 26 |
We have a custom FreeBSD patches that replace all __sparc64__ defines to |
| 27 |
__sparc__ [3]. If the code is really 64-bit related (most is not) then we use |
| 28 |
the __arch64__ define too. Only FreeBSD sources appear to use the __sparc64__ |
| 29 |
define as I've successfully built and tested large external packages such as |
| 30 |
postgresql, samba and many more and none of them use that define. |
| 31 |
|
| 32 |
Some packages assume that sparc CHOST is always sparc-*-* (bug #151715) - this |
| 33 |
is the case for Linux where the userland is always 32-bit and the kernel is |
| 34 |
64-bits, but for FreeBSD the kernel won't run any 32-bit code so the CHOST is |
| 35 |
sparc64-gentoo-freebsdx.x (x.x being the freebsd version). |
| 36 |

Thanks |

[3] __sparc64__ define is not a guarantee of 64-bit code according to gcc |
