skn Posted August 8, 2006 Author Share Posted August 8, 2006 However, according to the message posted on http://kernel.macosforge.org/, the source is not exactly the same found in the 10.4.7 software update: Source code for the kernel of Mac OS X 10.4.7 for Intel are now available. Several changes were made in order to publish the kernel (xnu) sources. As a result, the kernel built from these sources differs from the one found in the 10.4.7 software update. In order to accommodate these changes, several kernel extensions were also modified and must be downloaded and installed in order to run a kernel built from these sources on Mac OS X 10.4.7 for Intel.

Marvin Posted August 8, 2006 Share Posted August 8, 2006 They are already optimizing for SSE4, so bad news for AMD users. Just take a look in xnu-792.10.96/osfmk/i386/commpage/ directory files bcopy_sse4.s and bcopy_sse4_64.s. A quick search of new SSE4 only command show that PALIGNR is heavily used.

The OS will still be backwards-compatible with SSE3 since Apple has several products that don't have SSE4. They aren't going to prevent compatibility for current MacBook/MacBook Pro users. Isn't that logical? Link to comment https://www.insanelymac.com/forum/topic/23841-1047-xnu-source-code-released/#findComment-158570 Share on other sites More sharing options...

Just nice to see, that Mac OS X already using the latest instruction set (where available).
