There's a SSE3 emlator pdf http://xnu-dev.googlecode.com/files/SSE3%20Emulator.pdf It describes the preformance between Native SSE3, Maxxus (now gone :( ), and Voodo (faster by factor of 3). But ever since Snow Leopard, there is no "group" of people that work on the kernel anymore (ie: voodo kernel). every SL patched kernel is made by one person, and does not have the quality/tested needed to run in SSE2 only enviroment.. So the beachballing and high cpu usage is caused by the thread race/thread locking/Grand Central Dispatch problem... I guess the SSE3 emulator was still only for the 9.x.x kernel and not 10.x.x... or its missing some other SSSE3/SSSE4 (not SSE3) emulation? http://netkas.org/?p=175 and from voodo's latest news 1 Sep 2009 Snow Leopard is out, but the xnu kernel sources have not yet been released by Apple. According to our information, it will be released soon. The kernel source was released... September 12th, 2009 | 12:27 am xnu-1456.1.26 is released by Apple & it is available for download now. http://www.opensource.apple.com/release/mac-os-x-106/ http://www.opensource.apple.com/tarb...56.1.26.tar.gz but no more updates... |
Do people run SL without the described problems when they have a Pentium (4) that does have SSE3 instructions and this legacy kernel?
So, do you have Pentium (4) +SSE3, and do you use this/a legacy kernel without (described) problems? Let us know! :) Quote:

It works fine for me without any problems in 32-bit mode on an Intel Celeron M 420 (SSE3 but not SSSE3). I guess the mileage may vary on certain mobo's or cpu's. I do need testers though... |

I think there must be made some new dyld (32+64bit) specifically for AMD. The problem exactly is the sysenter trap (I'm not sure any/all AMD cpu's have it...). It is a 32-bit application which is launching. Maybe it uses some sort of mechanism for running 32-bit apps under 64-bit environment. I haven't examined the dyld sources yet because of no time. |
That seems quite complex Andy, if you need any extra info or further testing I'm willing. Anyway, take your time, you're quite busy creating hackintosh stuff and this is not a real problem.
Thanks for your hard work Andy. |

having problems using -force 64
hey guys i am having problems running the kernel on 64-bit on my SL 10.6.3 . I have installed the kernel and tried to boot the kernel in 64-bit using the '-force64' flag but it does not boot into 64-bit ( i know this by looking at the 64-bit kernel and extensions line because it says "no" ) . Can you please help me by telling me the correct way to boot into 64-bit. It would be very helpful.
