I wasn't aware of this!  It seems baloo has been busy all on its own:

$ balooctl status
Baloo File Indexer is not running
Indexed 6412 / 7195 files
Current size of index is 79.07 MiB

$ balooctl config show includeFolders
/home/michael

So it's been indexing my whole /home directory.  Will issuing a disable 
command survive a reboot?

Have you tried balooctl to turn it off? I think that's how I did it when
I tried plasma months ago.

The experimental use flag turns on the other arch's in gentoo-sources.
Perhaps that will help identify which is the relevant patch?

Are you sure it's QtCreator, etc and not the baloo indexer that's causing
problems. After upgrading baloo yesterday it slowed down my laptop all
day today. It just stopped. Baloo itself wasn't eating much CPU but it was
doing a lot of IO (use iotop to check).

And for future references, here's how I found out:

1. On the sources where you have the options highlight one of them and
   press ? (help). You'll see X86_32 under "Depends on:".

2. Hit ESC twice and then twice again to return to a menu with
   search functionality. Then type /X86_32 and hit enter. You'lll see that
   the option depends on !64BIT, so you need to disable CONFIG_64BIT for
   X86_32 to be available.

3. After disabling CONFIG_64BIT on the kernel where the options where missing
   I searched X86_32 again and this time it has [=y] next to it so it came
   on automatically and the options showed up but for some options you need to
   enable manually after enabling the dependencies.

This is fucking ridiculous. Baloo's kcm module is also part of plasma-desktop!
Now after being forced to update it the indexer is making my system very
unresponsive and I can't turn it off!

Which versions of Qt/KDE? I just installed stable KDE 5 on unstable Qt
5, as tiling window managers are not great all the time. I have not
noticed any problems so far related to rendering.

I can test this in a little while, but I'm busy working on some stuff
right now while logged in to i3.

[gentoo-user] qt-creator (and others) too slow

[Francisco Ares]

Hi, all,

Just upgraded to KDE 5, Qt 5 (as full as possible) and now QtCreator
frequently uses almost full CPU, a quad-core i5-4430. Any change on the
IDE, even just passing the mouse cursor over elements of an opened source
code file, makes the CPU consuption to the high tops.

It also happened when I tried some widgets using plasmashell, like the
analog clock and the Desktop widget. The process "plasmashell" eat up all
available CPU cicles.

Could it be something related to more deep details inside Qt basis?

Turns out to find funny QtCreator's description on KDE menu: "Lightweight
IDE for C++ ...".

Any hints to find out what is happening will be highly appreciated.

Best regards,
Francisco

That's what I get here, but help lists all the ones I get in
gentoo-sources, apart from MNATIVE, which indicates to me that those
options should be available, once I work out how to switch them on.

I don't use gentoo sources but I remember reading about gentoo patches
for processor specific optimizations and being tempted to try them. Is it
possible that is what you're refering to?

The vanilla sources only shows 5 choices for me on amd64:
(X) Opteron/Athlon64/Hammer/K8
( ) Intel P4 / older Netburst based Xeon
( ) Core 2/newer Xeon
( ) Intel Atom
( ) Generic-x86-64

And it shows a different set of options when I run it on an x86 machine.

is what's missing in mainline but part of -gentoo.

Re: [gentoo-user] no sound through headphones (now works)

[allan gottlieb]

I cannot explain the following.

I was about the try the last suggestions (use kill -9; load more sound
modules) when I, just for fun, retried alsamixer.  I did the usual
unmute everything and it somehow just worked.

I did nothing new and would not be surprised if, during the next flight,
the headphones fail again, but it is clearly not a kernel problem.

Thanks you all for your help.

Running a vanilla kernel here:

uname -r
4.6.4-vanilla

I've counted 24 CPUs listed in my '.config'.

Which one are you after?

[gentoo-user] Missing CPU options in make menuconfig

[Neil Bothwick]

I'm trying to do something with a vanilla kernel from kernel.org. Under
Processor type and features/Processor family, there are only a handful of
choices, whereas my portage-installed gentoo-sources lists many more.

The help page on the vanilla sources shows the full list, but they are
not available to pick and the help does not mentions an option to enable
to show these.

What do I need to enable?

[gentoo-user] Xen with Gentoo as dom0: sw or hw raid?

[Jarry]

Hi Gentoo-users,

I'm going to build a small server with Xen-hypervisor with
Gentoo as dom0 (if it is possible). Comming from ESXi-world,
there is no choice (only true hw-raid is supported).

But what about Linux? What's preffered way to go? Software-raid
(mdadm), or true hardware raid-controller? I have a few spares
(LSI-9271), these worked quite well with ESXi but I'm not sure
they are supported by Linux at all, and if there is actually
some way of monitoring controller-health...

Concerning sw-raid, I have used it for quite some time, but
never with Xen (is it actually possible?). Moreover, grub-config
for Xen itself is somehow more complicated and sw-raid could add
extra complexity...

So the question is simple. For Xen-server with Gentoo as dom0,
what do you recommend: sofware- or hardware-raid?

Any other general tips concerning Xen (particularly with Gentoo
as dom0)?

Jarry
