Thanks for offering your plan for gentoo-sparc. I'm interested in |
| 4 |
gentoo-sparc as well and I'd like to help if I could. Regarding the |
| 5 |
points you brought up, here are my thoughts. |
| 6 |
|
| 7 |
(1) Bugzilla |
| 8 |
|
| 9 |
In Feb. 2015 I was looking for sparc related issues to resolve and I |
| 10 |
found bug #532088, a SIGBUS crash in openvpn caused by an LZO bug. I |
| 11 |
worked with the LZO author to fix the problem and the fix is included in |
| 12 |
lzo version 2.09. I created a gentoo bug to describe the issue and the |
| 13 |
fix (upgrade to 2.09), #539760. It would be great to get LZO upgraded to |
| 14 |
2.09 because LZO is currently completely broken on sparc. |
| 15 |
|
| 16 |
(2) Installation |
| 17 |
|
| 18 |
The documentation seems to be in good shape, except for a couple issues |
| 19 |
I identified: |
| 20 |
|
| 21 |
a) The only filesystem tools that seem to be included on the live cd are |
| 22 |
e2fsprogs. This isn't really a problem except that the handbook |
| 23 |
describes the other filesystems such as xfs, js, etc. Is there a reason |
| 24 |
the other tools are omitted? If so, we should probably not present them |
| 25 |
as options in the handbook. |
| 26 |
|
| 27 |
b) The other issue I saw was that the handbook recommends -march=native |
| 28 |
when gcc doesn't even seem to support any "-march" flags on |
| 29 |
sparc, instead using "-mcpu" or "-mtune". I believe "-mcpu=native" |
| 30 |
should work similarly. |
| 31 |
|
| 32 |
As for the live cd itself I was unable to create a working system from |
| 33 |
the current image. As soon as I upgrade glibc from what's in the current |
| 34 |
stage3 tarball to the latest stable I get lots of "wait_for: No record |
| 35 |
of process 0" errors when running programs, particularly portage. This |
| 36 |
was the case compiling glibc with the gcc 4.7.x included in the |
| 37 |
current stage3 and with the latest stable 4.8.4. |
| 38 |
|
| 39 |
I'm not sure what the exact problem is. It may be related to the age of |
| 40 |
the stage3, currently from 2014-12-01. I was wondering if you had any |
| 41 |
ideas of what could be causing this before I try again. |
| 42 |
|
| 43 |
4) Once I get a working system I'm interested in getting systemd |
| 44 |
working. |
| 45 |
|
| 46 |
I'm also very interested in getting java working. There recently has |
| 47 |
been some work upstream in openjdk fixing linux/sparc support and as |
| 48 |
a result IcedTea 2.5.5 compiles and runs for me on debian/sparc. Because |
| 49 |
of this I'm certain we could put together a working ebuild for gentoo. |
| 50 |

Thanks, |
| 52 |
