Seems to be a problem here:

Code:
root@Q6600: ~# emerge -avuDN @world

These are the packages that would be merged, in order:

Calculating dependencies... done!

Would you like to merge these packages? [Yes/No]

>>> Verifying ebuild manifests

!!! Digest verification failed:
!!! /mnt/ext3_STORAGE/usr/portage/sys-kernel/ck-sources/metadata.xml
!!! Reason: Filesize does not match recorded size
!!! Got: 812
!!! Expected: 0


I re-created the manifest with 'ebuild ck-sources-3.9.11.ebuild manifest', and things seem to have straightened out, but I don't know why it happened to begin with.

Just a heads-up, if anyone else has the same trouble.

You did right.
Most generally, that sort of error is corrected after re-syncing the portage tree.

No, apparently something did go wrong with that commit; I am not able to pinpoint why, but it recorded the metadata.xml having size 0 for some reason.

Quote:
revision 1.345
date: 2013-07-24 21:41:39 +0200; author: tomwij; state: Exp; lines: +8 -8; commitid: 533851f02df34567;
Updated manifest; in the previous commit, the size for metadata.xml somehow got recorded as 0.

(Portage version: 2.1.12.13/cvs/Linux x86_64, signed Manifest commit with key 6D34E57D)


So, syncing around an hour from now; that should be resolved, but you can indeed do something like `cd /usr/portage/sys-kernel/ck-sources ; repoman manifest` to fix it up.

This time I seemingly loose my bet:
I just run a recently compiled linux-3.10.3rc1 with BFS enabled - without problems.
But I have disabled nearly all of the newer kernel features ...

@aCOSwt, what patch did you talk about eventually needed?

[edit] Uuups, after 2 hours crashed and totally freezed while heavy duty compiling in a chroot. And I must mention I tainted the kernel using the proprietary nvidia with the inofficial patch ...

Teegrins!


Awesome work, Con Kolivas, aCOSwt, et al. I've been using these sources for quite a while, and they are quite impressive indeed! Reading about the past of the sources was very interesting, and I am glad that Kolivas returned to it.
Hopefully it wont be as stressful as it seemed to once be (settling to a patch-set is no doubt helping that, or so I'd imagine).


Anyblue, I've come upon some weirdness with the 3.9.11, and wondering now if it's just me (can't find it mentioned anywhere):

Code:
net/bridge/br_multicast.c: In function ‘br_multicast_del_pg’:
net/bridge/br_multicast.c:272:38: error: ‘struct net_bridge_mdb_entry’ has no member named ‘timer_armed’
make[2]: *** [net/bridge/br_multicast.o] Error 1
make[1]: *** [net/bridge] Error 2
make: *** [net] Error 2

Now, I am a complete noob with these things still, but I tried my best to make sense of things as I delved deep into the source code while I also sought the internet for any related information (losing a good portion of the day to being amused by mailing list posts from Torvalds), and came to a conclusion in the end. Would I be completely off the map if I were to claim that this patch:

I figured the error message makes sense since the “timer_armed” doesn't seem to exist at all. The sources indeed build after reverting the commit: c7e8e8a8f7a70b343ca1e0f90a31e35ab2d16de1

Perhaps my kernel configuration is just out of whack, but this really seems wrong to me. ^^;


Again, thank you, and I would appreciate if someone wiser could confirm and/or point me my error(s)!

And is responsible for the problem you experience. You are correct.

I'll make my best to push a ck-sources-3.9.11-r1 (in wich this patch will have been removed) before tonight.

In the mean time, if you are in a hurry, you can :

1/ #cp ck-sources-3.9.11.ebuild ck-sources-3.9.11-r1.ebuild
2/ Edit the ck-sources-3.9.11-r1.ebuild and change the line reading K_GENPATCHES_VER="16" against K_GENPATCHES_VER="17"
3/ Save and exit
4/ #repoman manifest

Then emerge this package.

Hi All,

When I want to compile the ck-sources-3.9.11 using genkernel - it is comfortable for me - then I got the errors below:

Code:

configuration written to .config

*** End of the configuration.

Should I attach the full genkernel log? It is huge...

There is no problem at all. Btw, I should try it manually, but I'm a lazy human... :) I'll do accordingly.

this thread is about choice + ck stuff

so I figured the following might be interesting:

http://marc.info/?l=linux-kernel&m=137521302202537&w=2

latency cut-down by 80% :!:


it's still RFC - so let's see how it develops ...

BFQ occassionally tends to hardlock for me - seems like they haven't found the cause yet :(

so I'll meanwhile use CFQ instead ...

Please read my answer to Chiitoo, 6 posts above.

I must apologize as I still did not push the 3.9.11-r1 as promised. I have been bothered by a MySQL upgrade then 3.10.3 and 4 came quickly... with their loads of problems...
Act as I suggested to Chiitoo or... be patient.

I made a backport of bfs-442
for use with LTS kernel Linux-3.10:

Found in attachement of bug

Thanks, it seems to be running OK :)

I was interested in the new check for throttling:

Quote:
The other significant change is to check for throttled CPUs when choosing an idle CPU to move a process to, which should impact the behaviour and possibly throughput when using a scaling CPU governor, such as ondemand.


For (hopefully) convenience, here's a diff from BFS 440 to your 442, created by applying both to vanilla kernel 3.10.15.

Edit: And here's Alfred Chen's patch, in proper format.

@Paul, three hours later than me at ck-hack.blogspot.com "Alfred Chen" showd a patch where he relocated mutex_lock and mutex_unlock. What do you think of it:

Alfred Chen puts the
mutex_lock (respective mutex_unlock)

outside of
for_each_online_cpu(cpu)

If mutex_lock is meant for one cpu
this sound reasonable? Is it?

Alfred Chen's patch runs OK too - that's about all I'm qualified to say.

I kinda noticed a hang at startup, a couple of times with kernel 3.10 & BFS, but it coincided with me playing with kernel & ACPI settings, so I can't reproduce it for a proper test.

And here's another patch for improved ondemand (main patch).

So, to recap, the patches to apply to kernel 3.10.x are:

    BFS 442
    Alfred Chen's mutex patch
    This ondemand recalc patch

It's all working stably for me.

Edit on 20140109: kernel 3.10.26 had a trivial change, causing these patches to need refreshing. Here's those 3 patches, merged into 1 patch to apply to kernel 3.10.26 :)

@Paul +1
Yes runs well for me. But
There is a BFS patch of
+#define DEF_FREQUENCY_UP_THRESHOLD (63)

For me the ondemand patch runs better with the original value
-#define DEF_FREQUENCY_UP_THRESHOLD (80)

The DEF_FREQUENCY_DOWN_DIFFERENTIAL value was obosleted anyway...

Should we ask Con Kolivas to outsource the patching of
drivers/cpufreq/cpufreq_ondemand.c
into the ck1 patchset?

It's just a default. I go in the opposite direction, to keep gaming smooth:

Code:
echo 50 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo 50 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor

@aCOSwt:

Is there any hope that there will be further updates, or are we now stalled at 3.9? Things have been pretty silent here.

I saw the problems in Bug #479382, and am thinking maybe you have had enough proxy maintaining :)

I, for one, appreciate all that you have done, Eric. Thank you.
