When new XP release will support SSE3 ?

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

Windows XP Service Pack 2 is mostly about security. It will give you tools to easily view, understand, and control the security aspects of your computer. It includes changes in the operating system to nearly every area related to computer and network security.

A pop-up blocker for Internet Explorer, a new Security Centre, and a new and more intuitive interface for wireless networking are some of the most visible components of SP2.

If you are wanting long-term CPU upgrade capabilities, now is the wrong
time to invest in a new CPU unless that CPU has the new pin designs
being developed by both AMD and Intel. Most of the P4 and AMD Barton
are near or at a dead end in the socket design, leaving no upgrade path.

Hi

There are News Groups specific to SP2. Someone there may be able to help
you:

Answer is never, but that is just my educated guess.

I have disassembled kernel from SP2 RC1 and haven't found MONITOR/MWAIT support in it

Linux community already implemented this nice feature into the kernel as of 2.6.4

Only thing different in SP2 is new processor driver (intelppm.sys) which seems to be the same or at
least similar to the one mentioned in Knowledge Base which is meant to support mobile Prescott power
management features.

What is surprising that it installs itself for my Prescott 2.8E and if I do some profiling in VTune Performance
Analyzer 50% of the clockticks come from the driver and other 50% from the application I am profiling -- IMHO
that is a bit wierd.

IF ANYONE FROM MICROSOFT IS READING THIS:

PLEASE INCLUDE UPDATED KERNEL SYNCHRONIZATION PRIMITIVES
(MONITOR/MWAIT INSTEAD OF SPIN LOOPS) FOR PRESCOTT CPU IN SP2 FINAL.
SSE3 IS APPLICATION SPECIFIC BUT MONITOR/MWAIT BELONGS IN THE KERNEL!!!
