Yes, but either way, it is the PPC fetching the PVR, not the 68K - which was my original point ;-)

[Piru]

Well, actually for PUP it just fetches the stored value from the library base, and with original ppc.library it's all pure m68k code.



Anyhoo, this hardly is any rocket science.

Ah, is this why it often misreports the hardware then (PUP, I mean, it often reported my 240MHz PPC as 160MHz, despite the fact the CPU is definately a 240MHz part)?

-edit-

- unless the value in the library base is hard coded, at some point during initialisation it must be read from the physical PVR, regardless of what happens on subsequent library calls...

In answer to the topic subject... They all do! :lol:

In most cases that was just applications being buggy. They assumed the PLL multiplier value was direct multiplier, instead of index to multiplier table specific to each CPU (well some CPUs share the PLL multiplier tables). For example some Doom version blasted "buggy ppc.library" for this, when in fact the app itself was broken.

But if your CPU speed appears randomly change between 240 and 160, then I have no clue.

Sure, it's read at library init. However, your query doesn't trigger any PPC code execution... :-)

Me too, hehe

Grew up with their movies, seen them all  ;-)

I too. :-)
In germany the movies are very popular. There is a nice german fansite at: http://www.budspencer.de
