 Posted: Sat Oct 30, 2010 1:23 am Post subject: [SOLVED]gentoo-2.6.36: EMBEDDED deactivates a lot of options |
 |
|
I emerged sys-kernel/gentoo-sources-2.6.36 with USE="-build -symlink" and when I activate General setup -> Configure standard kernel features (for small systems) (CONFIG_EMBEDDED) a lot of options become deactivated/invisible. For example Support for paging of anonymous memory (swap) or Device Drivers -> Block devices (NEW) and Device Drivers -> SCSI device support becomes empty. A lot of file systems disappear too.
Should I file a bug report or is this some new change that makes sense?

All the other options you mentioned are there too.
... Which is odd because gentoo-sources currently contains only one patch (bootsplash). Make sure it's not some option you unchecked that disables them. |

To be sure I reinstalled the package. No /usr/src/linux/.config was present. I ran make menuconfig in /usr/src/linux and the only thing I did was activating Configure standard kernel features (for small systems). Same problem.
Maybe this is improtant: | Code: | # emerge --info

Do you mean you don't have this problem and this is what you see in your kernel configuration tool?
To answer your question. It does not only gets unchecked. As soon as I press spacebar over Configure standard kernel features (for small systems) it simply gets erased of the list, when I press spacebar again to deselect it the swap option appears again in the list.

yes, using your USE="-build -symlink" emerge gentoo-sources and make menuconfig and the only thing I did was activating Configure standard kernel features (for small systems)
So it appears I have repeated your steps and those don't become erased, so I can only think something else is at play.
As you can read from my post, I have a different flaw with 2.6.36

well, gets more & more curious. I executed
| Code: |
emerge -C gentoo-sources-2.6.36
USE="-build -symlink" emerge gentoo-sources
cd linux-2.6.36-gentoo
make menuconfig
|
which yielded

noting it is checked and the same as my previous post. then
| Code: |
idella@genny /usr/src/linux-2.6.36-gentoo $ sudo make mrproper
CLEAN scripts/basic
CLEAN scripts/kconfig
CLEAN include/config
make menuconfig

yielding

plus what I entered in my initial post.
So Jaglover can reproduce using make mrproper, I can't reproduce it at all.
That's the what, so now for the why! I don't know. I wonder if that something else at play is the underlying system profile.

Maybe its because of the architecture. You have x86, me amd64. What about you Jaglover? |

I have a 64 bit gentoo. I can create a kernel for it and try it, not now; tomorrow.

I can't expalain, but this is in the gentoo64. There must be something else at play. Can keep guessing. Perhaps a setting in the underlying kernel of your system, your uname -r config??

Hmm
yes, I can't reproduce it as I've demonstrated and can't explain it. If your initial query was
Do I make a bug submission?
then no. My attempts to reproduce it are enough to indicate there is something else and the first thing a dev does with a bug submission is to reproduce it.
Have you looked at your underlying gentoo system kernel config? What importance is it for you?

I found the solution. When you configure a fresh kernel source the Enable the block layer (BLOCK) is hard checked, meaning you can't uncheck it. When you activate Configure standard kernel features (for small systems) BLOCK becomes changeable and unchecked! So now SWAP is missing it's dependency. You simply have to got back to the top level and check BLOCK manually. Now you can have SWAP and EMBEDD at the same time.
I didn't bother checking options on the top level because I had never manipulated them before. So it was a pretty trivial problem but I blame the unintuitive behavior of the kernel config. How should I have known it would uncheck something that was hardchecked when I ADD an option?!? |
