nowadays, looking at those output strings, seems that something changed between them

it would be nice to see the source code diffs maybe i can try to see something..

RC8 is the best build i have tested. with RC12 various programs crashes with EXC_BREAKPOINT exceptions

@bcobco and happel,

Am I right to say you are both using Athlon processors? ADHDMedia and I are both using Phenom II x6 processors,the detection may be different as I have audio problems using bron kernels rc8 and rc12 but with shane_kernel audio works flawlessly using flag busratio=14

I am running 10.6.7 and 10.7.5, but on separate drives, and I checked both plists and neither has any busratio or fsb flags (I've never had to use them with SL)

 

Is there anything else that would cause me to not be able to set the busratio with a flag when I boot with the Bronzovka kernels? Besides it being hardcoded into the kernel...?

I figured it out, go into your bios and disable CPU turbo...Mine is usually enabled, bringing my processor speed to 3.31GHz, as can be seen in the screenshot mine is currently on the stock speed of 2.81GHz, so bron_rc12 kernel is properly detecting the busratio now....

 

For those having audio stuttering problems due to incorrect bus ratio:

Disable AMD Turbo boost

I don't have that as an option in my BIOS. I am, however , manually overclocked from 3.01 to 3.51 GHz. Could that be my issue? It never has been under SL...

Remove the overclock, test it on the stock speed...should work properly...

You do have the ability to save your current bios settings right? If you can, save them and remove the overclock...

If you require any additional help, we should continue in the help topic

Tested that theory, and its a no-go for me. Even under stock clock speeds, my bus ratio is still detected as 17, throwing everything off.

nevew saw that.. maybe my bios does not have it, or amd kuma does not have it

 

i would like to suggest some performance tips:

disable all ASPM

disable C1E

disable everything related with power save

remove applegraphicspowermanagement and all applepowermanagement kexts

for CPU FX / Phenom / Atlon ? i386 / x86_64 ?

 

je vais le tester ;)

Hi, is restarting working for you?

Download mach_kernel_rc13!

Fix cupid for old processor's .

I add flag "busratio=x" , x - figure.

It is you can write flag busratio !

Please try !

 

RC13 is giving me an error on launching Cinebench. Other previous versions would cause the red pixel error, but this is the first kernel that has caused it to refuse to open completely. RC8 seems to be running smooth as silk on my system now, however.

 

Thanks for all your hard work!! Much appreciated.

 

Not sure if this is related to the kernel, but some of my .mov files are badly corrupted, and show a green or black thumbnail. Others play fine. This is the same systemwide, be it thru Quicktime Player, FCPX, MPlayerX, iTunes, etc...

 

Is this a kernel issue? Or something I should be asking in the Help Topic...? Thanks guys.

I get no issue with fsb & busratio detection

 

 

but I get some different readouts of the SSSE3 & SSE4.2 detection

 

Here is the report:

 

 

 

 

sysctl: SSSE3 = 1 & SSE4.2 = 0

 

cpu_1a.png

 

 

 

dmesg: SSSE3 = 0 & SSE4.2 = 0

 

cpu_1b.png

 

 

 

sysctl: SSSE3 = 0 & SSE4.2 = 1

 

cpu_1c.png

 

 

CPU-X : SSSE3 = 0 & SSE4.2 = 1

 

cpu_1d.png

hi bronya

congrats! rc13 kernel is pretty stable

cpu: amd athlon 64 x2 7850 be

 

somewhere opemu has a bug!

i dont know how can i get more information of what is happening. nowadays everybody can reproduce the bug:

launching Maxima (Maxima, a Computer Algebra System. http://maxima.sourceforge.net/), or trying to compile it with HomeBrew (The missing package manager for OS X. http://mxcl.github.io/homebrew/). seems that the issue happens when it calls SBCL (Steel Bank Common Lisp. http://www.sbcl.org/)

the affected thread will not respond, and the kernel will enter a loop, printing "32 bit opemu wrong instruction" or "64 bit opemu wrong instruction".

 

ps: if there is a way to get more information of opemu please let me know so as we can obtain moar information
