10.7.4 AMD Kernel

[sulphide]

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

[R:A:W:X86]

Thanks for testing so far.
Still working on some more improvements to the code, which I hope will make this more attractive for other people to work on this.

This behavior is absolutely unexpected, unless you are using -legacy bootflag.

The Kernel still enters 64-Bit enabled boot-up by default.
-force64 is not associated with any function and not required on SSSE3-AMD - even less on Vanilla-Intel.

Just to note:
Using this Kernel permanently on a Vanilla capable system is not recommended.
The Kernel source code Apple releases doesn't 100% match the Kernel, they are releasing with their OS.
Beeing compatible is just a feature for stuff like multiplatform Boot-CD solutions, etc.

hello,

Actually, I had mistakenly left-legacy in the plist (hoops!) For my tests, I using the same OSX 10.7.4 on my AMD Phenom and my Intel xeon .

That said, your kernel is royal! perfs are on the rise and smoother video! Hats off Sir!

There are only 64 bit mode (k 10) will fix the problem of various bug and we will have AMD configuration at the top!

The Phenom / Atlon still remains beautiful and deserve our respect!

I hope to that you will come to us out the kernel in 64 bit AMD K10.

Big thank you again for your work.

je précise , le proc est bien unlocker en x6 à 3,01 ghz mais pas à 3,41 ghz comme affiché dans les tests , je suppose que c'est le turbo .

Particulary I would be interested in having it tested on all kind of non-SSSE3-capable AMD & Intel-Nehalem CPUs DOWNLAOD

Thank You R:A:W:X86 !
i installed 10.7.3 using bronzovka_mach_kernel_v4 since then just left it alone til next benchmark. so i see you posted a kernel for 10.7.4 so i upgraded to 10.7.4 tried your kernel and got reboot after system files load. so i used the 'roll back trick' i used either bronzovka_mach_kernel_v4 or v6 and replaced the kexts AppleFileSystemDriver.kext & IOStorageFamily.kext with the ones from 10.7.3. however, before i could post my results i see your new kernel and give it a shot and voilà lion loads! so heres my 2¢ on your kernel...great work so far
thanks for all your hard work 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.

R:A:W:X86 first I want to thank you for your great work!!

I tested your first kernel and my fresh 10.7.4 installation works great with flags -v npci=0x2000 -legacy!

But your newest one from today just restarts my pc over and over again, I tried the following flags in many combinations: -force64 -legacy arch=x86_64/i386 -v -f npci=0x2000 nothings helps!

If i can help you anyway tell me


My System:
- Bulldozer 8120
- Asus M5A97
- Geforce 9500GT
- 10.7.4 from Appstore with Myhack and your kernel a clean install without any problem

Same for me, fx-8150, m5a97 (same), geforce 560ti. Restart after all kexts. This is without -legacy flag, of course.

Some answers - before you ask the corresponding questions: If the on-the-fly opcode patching routines can be fixed, they will not affect sysenter crashes on 64-Bit enabled AMD (Bulldozer) systems. Currently it will handle mach-o executables only, no shared librarys and frameworks Most likely it will also not fix 64-Bit boot-up for the others.

hello,

I tested your new kernel (raw), big step forward, starting the PC is a little space! I no longer crash application, I FaceTime which is very long to open, save it for QuickTime bug screen,
I have a CPU that bubbles!

Code: raw -legacy GraphicsEnabler=No PCIRootUID=1-v-f

the rest is in the plist.

thank you for your job!

[ham4ever]

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.
