re: Linux 3.5-rc7

Compiled 3.6-rc7, with a hz timer of 3956 for a "natural" psychovisual  
profile jitter level in OpenGL, and a shaved config for minimal jitter.

Also changed the 10ms filter in fair.c to 1. And I suggest the whole  
filter to be removed. https://lkml.org/lkml/2012/9/30/78

There is very few clicks with ALSA + onboard soundcard at 0.3ms lantecy  
now, without RT-threads.

Meaning os-jitter is near optimal for audio/video. I think few care once  
it is below 0.2ms.

Ofcourse one always wants lower, but at that point, things feel like  
hardware, and becomes unnoticable to the user.

Peace Be With You.

I'll bite - how did you measure the difference between 3956 and 4000?

The other stuff in your note sounds sane, but I'm having a hard time
believing that 3956 was arrived at in any sort of systematic or measured
way - it smells like cargo cult programming to me...

Well, you might not like the answer. It is based on purification of the  
senses by meditation. You can read about it here.  
http://www.youtube.com/watch?v=Cz8fCnMBnuc&feature=related

And then in a pure state, simply tuning the hz, to ones liking, trying to  
find a "natural value", which probably corresponds with the fact that,  
natural phenomna such as wind, temperature, influence similar phenomena to  
"jitter". Also based on 10 years of work with DSP ;)

Don`t worry about the 3956 timer anymore though, I use 90hz now. For some  
reasons many places online state higher HZ = higher resolution, and lower  
latency. For audio and opengl this is not true. Audio still has the same  
latency at 90hz, and OpenGL performs better, with less jitter.

You can take my low-jitter kernel for a spin, here.  
http://paradoxuncreated.com/Blog/wordpress/?p=2268
Particulary note that OpenGL in doom3 is very smooth, (if you have any  
jitter try killing background daemons). Audio latency is stable at 1ms,  
and few clicks at 0.3. I have also run it at 0.3ms stable latency with  
realtime threads, with a firewire audio card. Simple HDA soundchip seems  
to perform poorer for some reason. One would think that an onboard  
soundchip would have less potential latency.

The whole system runs well.

I am also using this info for thoughts on cfs. If granularity should be  
tuned up for more processes running, maybe related granuarlity to  
processes, for best resource usage. Currently also I think the 10ms filter  
could be replaced with a simpler hold logic, so you don`t have to update  
it more that neccesary, or compute share based on filters impulse response.

Just some small observations.

Peace Be With You.

Hi,

  Building modules, stage 2.
  MODPOST 3571 modules

WARNING: drivers/scsi/fcoe/libfcoe.o(.init.text+0x1f): Section mismatch in reference from the function init_module() to the function .exit.text:fcoe_transport_exit()
The function __init init_module() references

This is often seen when error handling in the init function

The fix is often to remove the __exit annotation of

That fixes it.

Tested three cycles.

Compiling TuxOnIce 3.5-rc7 with that patch now to verify if that fix work 
there, too. TuxOnIce is still so much faster than in-kernel-suspend ;).

There's a one-liner fix for this bouncing around.

Appended is a white-space damaged cut-and-paste version of the fix, so
you'll need to either find the original patch (search the kernel
mailing list for "Excessive delay or hang during resume from system
suspend due to a hrtimer commit"), or just edit in the one-liner by
hand.

This should fix it (there's apparently a question on whether the
"false" should be "true", but that's an independent detail, it's worth
verifying in this form regardless).

Regresses badly on resume from in-kernel hibernation. I.e. hangs with some 
red graphics artifacts on the tty. The same artifacts appear for a short 
time with rc6 + some commits as well, but there then X.org is available 
again.

2437fccfbfc83bcb868ccc7fdfe2b5310bf07835 – thats rc6 + some commits – 
works, while exactly rc7 does not.

No bisection tried so far. Maybe tomorrow. It shouldn´t be that many 
attempts and kernel compiles are fast on the ThinkPad T520 with Intel i5 
Sandybridge + integrated graphics – no NVidia – + Intel SSD 320 where this 
happens. No other machines tested so far.

Kernel configuration available if desired.

Crahses and burns on Intel Poulsbo systems with a blank screen.
Fortunately I know why - your tree is short the patch for it that went to
Dave some time before -rc7. I'm just testing that v -rc7 now on the psb
boxes.

More strangely I also now get no backlight on one of the other
boxes despite it passing testing in previous -rc releases. I'm digging
into that but I do have an apparent workaround which just disables
backlight support as before on the relevant chip.

Hey guys, remember how things have been stabilizing and slowing down,
and all the kernel developers were off on summer vacation?

Yeah, we need to talk about that. Because I last week I thought that
making an -rc7 was not necessarily realy required, except perhaps
mainly to check the late printk changes. But then today and yesterday,
I got a ton of small pull requests, and now I find myself releasing an
-rc7 that is actually bigger than rc6 was.

Not cool, guys. Not cool.

Now, admittedly, most of this is pretty small. The loadavg calculation
fix patch is pretty big, but quite a lot of that is added comments
(*big* added comments). . But there's Andrew's patch-bomb, there's
media fixes, there's random SOC fixes, powerpc fixes, USB, sound, you
name it.

Ok, so it's still not *huge*, but it's bigger than -rc6 was. I had
hoped for less.

But go forth and test. Make sure it's all good. Because I really wish
I won't have to do an -rc8.
