CPUID test piece.

[hutch--]

I have the attached test piece tested on the hardware I have running here but there are old timers and AMD hardware that I don't have access at so if it is not to much innconvenience, I would appreciate people with different hardware to test this app and publish the results for each processor they have available.

These are the results I have on the Intel hardware I have running. 0 means not available, 1 means instruction set IS available.

My young brother can be useful occasionally, tested it on 2 AMD machines.

The next one is unusual, its an AMD Sempron that gave unusual results with the long ID string.
CPUZ says its a AMD Sempron LE-1150 (Sparta) Socket AM2(940)

I have done some work on the earlier one, this one calls each routine and returns results that are not printed locally in each proc. I used a suggestion of Dave's to try and pick up the earlier processors from PIIIs back to later 486s. problem is I have no way of testing old timers as I no longer have any that will run.

I get these types of results on the boxes I am using.

I don't target anything earlier than Win2000 but I would be interested to see how this version works on PIIIs and earlier. The processor cutoff will probably be something late enough to run Win2000 but I do not expect that it will run correctly on earlier hardware or win9x series OS versions.

the worst OS for this stuff is Windows CE (for embedded systems)
on the plus side, you'd think they already know what CPU they have if they developed an embedded system - lol

the problem is - some versions of CE are "buildable" and the designer has the opportunity
to trim down the OS - i don't know what that entails, nor was i able to find a clear answer for
whether or not CE supports multiple cores
i suspect, in the near future, it will have to

muliple cores means there is a possibility that CPUID will execute on one package one time
and another package the next time - however likely or unlikely
with most motherboards, the packages are the same device, so it makes no real difference unless you are reading cache parms
there are a few instances where the packages may be different, however
that makes it a good idea to affinitize to a single core, i think

if a programmer is to use this routine in an app that is distributed, he may want it to work on all systems

Dave,

The only part of the example that I see as important is the available instruction sets and its primarily so a program can choose whether it uses SSE2 or SSE4.1 rather than and real interest in the old stuff, most of which cannot run Win2000 or later. Microsoft will shortly pension off XP SP3 so I don't see the point of wasting the effort on very early AMD or Cyrix hardware.

The ID strings are OK as headings on sysinfo dialogs but they are not much real use in determining if you can use an SSE instruction or not.

Hutch,
your tests aren't exhaustive. The Phenom has SSE4a (not SSE4.1 or SSE4.2)
The K6-III has 3DNow!
Neither of these is detected in your tests but maybe you aren't interested in looking for them.

Paul.

Some of the older chips (pre CPUID) could be identified by looking at things like the barrel shift, flag bits, prefetch queue size (self modifying code). For instance the the 386DX and 386SX could be identified by different prefetch queue sizes. I need to dig up the DOS code I had that would identifiy 8080/86,V20/30 thru Pentium III Coppermine.
