10.7.4 AMD Kernel

[R:A:W:X86]

update 2012-05-31:

The main part of the code changes that once have been gathered by AnV are now implemented in a working Kernel.

Most likely non-SSSE3 capable AMD systems will still freeze after hard disk initalisation, unless you are using the -legacy bootlag. (altough I could not test this)
We still need to find a fix for this.

atm NOT implemeted functions are:

• auto patcher function for mach-o executables
• some detection code in the real time clock handler (should not be so important as we are all using decent bootloaders)

In addition to the Kernel diff the Download contains two additional diff-patches that will add those code changes.
Both will compile fine, but cause malfunction during boot up.
I am going to diff those files between xnu-1504 & xnu-1699, maybe it is fixable by some "Snow Leopard reimplementations"...


Some answers - before you ask the corresponding questions:

• Most likely an integration of the auto-patcher will not fix 64-Bit boot-up for the non-SSSE3 CPU users. (Actually I am not 100% sure what the origin of the problem is & I do not hold a hardware platforms that allows testing on this.)
• Why I am working on this anyway: I hope this will solve a lot of application crashes and other bugs & add some stability to the -legacy mode.
• Some people (including Bulldozer users) may need to advice the correct clock multiplier to the Kernel as auto-detection fails. Examples: busratio=13 (multiplier 13) or busratio=105 (multiplier 10.5)

this build still has to be considered an experimental release, made for testing purposes & to allow further development!

DOWNLOAD

As already mentioned above, source patch is included.
Would be great if some people with more competencies would contribute to this.

With that kernel is expected that Photoshop CS6 works on Phenom II X4 970BE?

fx-8150, 64-bit, reboot right after kexts loaded. previous kernel works ok even in 64 bits.

i tested your both kernels , and both great in this specs:

AMD Athlon II x3 435





second kernel open apps soo fast and lion so smooth

just so far i noticed i cant see app in activity monitor like in pic




Update : after using 1 hour, apps appears in Activity monitor

update 2012-06-03

As the Kernel features some patch made by AnV that automaticaly turns code signature to valid, I was able to fix 32-Bit Apps to work on 64-Bit enabled AMD machines (Bulldozer).

This requires sysenter traps to be patched in /usr/lib/dyld and /usr/lib/system/libsystem_kernel.dylib
Maybe some additional shared libraries need to be patched if XCode is installed (untested).

There is an Lion compatible Version of amd_insn_patcher by AnV that works for Lion. Old versions will not work as the sysenter trap has changed in Lion.
Get it from here:
http://osx86.co/f36/legacy-kernel-10...post55947.html

Usage: amd_insn_patcher unpatched_file patched_file

Be sure to fix file permissions before you copy over & use "sudo update_dyld_shared_cache" afterwards.



So far all my Apps 32- & 64-Bit are working without issues.

THANKS!!! It's ok now Don't know why my busratio was not in the kernel_flags it was separately in the end of boot.plist

32bit apps running in 64bit mode, is that right?
GREAT R:A:W:X86 !!!

only revisions that worked for me were the ones that you edited.

But how do I apply this patch to the Bulldozer? You would not have it applied to the kernel?

Thank you so much
Also Bulldozer My thanks

Hi! I tired your and Bronzovka's kernel, but both didn't work. It's stuck at "BSD Root : .." .
More information : http://www.insanelymac.com/forum/ind...owtopic=279629

How to fix that?

Thanks in advance! :-)

So, exactly which link is supposed to be the latest ?
