Interrupts: help with tests

[Karlos]

I will try after work today :-)

[Karlos]

Done!

I also included some quick amigados scripts I wrote to run all the tests with each cache combination.

Whatever it is you are doing, the CIA2 version is way the fastest ;-)

I can't configure the number of waitstates, just wether there are any or not (for each CPU) and wether or not to use precharge (again for each CPU).

For best OS3.x performance I have found that 68K with no waitstates or precharge and PPC with no waitstates but with precharge works best.

Without precharge, the PPC seemed to be a little unstable. I should check that again actually, it might not have been the true cause.

Instead it is just yes/no ?

I'm afraid so. The option is simply on/off for all the memory parameters.

How do you perform the configuration? boot-menu?

Yes, in the BPPC / CSPPC bootmenu (that you get when holding Esc). Once there you can go to the RAM settings and choose one of the following three options from a cycle gadget:

60ns / 70ns / Free Config

Unless you choose Free Config, the other options are ghosted out.

The remaining options are for Read Waitstate, Write Waitsate and Precharge (seperately settable for both 68K and PPC).

Basically all these options are simple on/off switches. You can't manually set any timings.

Better still, make it appear to be a benchmark (timing the process). People always love outbenching other people :-D
