Hi everyone, |

|
| 3 |
Can you please review the following news item. The item is |
| 4 |
self-explanatory. The only thing I'm iffy about is whether or not I |
| 5 |
should specify a date (Oct 11) for when I'm going to make the switch --- |
| 6 |
or should I just push the news item out the day I do make the changes? |

To accomodate the new multilib approach in Gentoo, the mips profiles will be |
| 18 |
changing on Oct 11, 2014. The new profile structure will be as follows: |
| 19 |
|
| 20 |
[1] default/linux/mips/13.0/o32 |
| 21 |
[2] default/linux/mips/13.0/n32 |
| 22 |
[3] default/linux/mips/13.0/n64 |
| 23 |
[4] default/linux/mips/13.0/multilib/o32 |
| 24 |
[5] default/linux/mips/13.0/multilib/n32 |
| 25 |
[6] default/linux/mips/13.0/multilib/n64 |
| 26 |
[7] default/linux/mips/13.0/mipsel/o32 |
| 27 |
[8] default/linux/mips/13.0/mipsel/n32 |
| 28 |
[9] default/linux/mips/13.0/mipsel/n64 |
| 29 |
[10] default/linux/mips/13.0/mipsel/multilib/o32 |
| 30 |
[11] default/linux/mips/13.0/mipsel/multilib/n32 |
| 31 |
[12] default/linux/mips/13.0/mipsel/multilib/n64 |
| 32 |
[13] hardened/linux/musl/mips |
| 33 |
[14] hardened/linux/musl/mips/mipsel |
| 34 |
[15] default/linux/uclibc/mips |
| 35 |
[16] hardened/linux/uclibc/mips |
| 36 |
[17] default/linux/uclibc/mips/mipsel |
| 37 |
[18] hardened/linux/uclibc/mips/mipsel |
| 38 |
|
| 39 |
There are a few points to note about the change: |
| 40 |
|
| 41 |
1) Only the glibc profiles (1-12) are affected. The embedded system |
| 42 |
profiles |
| 43 |
(13-18) will not change. |
| 44 |
|
| 45 |
2) The glibc profiles will now explicitly state the ABIs. In the case of |
| 46 |
non-multilib systems (1-3, 7-9) the stated ABI will be the only ABI |
| 47 |
available, |
| 48 |
while in the case of multilib systems (4-6, 10-12) the stated ABI will |
| 49 |
be the |
| 50 |
default ABI, and the others will be available by setting ABI_MIPS in |
| 51 |
make.conf. |
| 52 |
|
| 53 |
3) Profiles 1 and 7 are strictly 32-bit userland, but can run under either a |
| 54 |
32-bit or 64-bit kernel. They will have CHOST = mips-unknown-linux-gnu and |
| 55 |
mipsel-unknown-linux-gnu, respectively. All the other glibc profiles |
| 56 |
(2-6, 8-12) |
| 57 |
are 64-bits userland and will have CHOST = mips64-unknown-linux-gnu or |
| 58 |
mips64el-unknown-linux-gnu. |
| 59 |
|
| 60 |
4) Only users of profiles 1 and 7 need to change their profiles sym |
| 61 |
links using |
| 62 |
`eselect profile`. However, all users should be aware of the CHOST value on |
| 63 |
their system to ensure it remains unchanged after the profile updates. |
