Yeah,this should be remembered as "there is no UDMA without April,
as someone pointed some time ago..."

Way to go!

I will not pop the champagne untill tests have been running a few days in different kind of load situations.... keep cool.

Is that 16Mbytes/second. using 68k emulation in multitasking with those others oh

Imagine if that screenshot would have been released 1 Apr 2004 ...

Eeeeexcellent!

So, is this fresh from Hyperion, or has it made a run with the beta-testers?

It won't be included with the pre-release, or? (Please say that this is what's been holding it up this time around!)

When will someone include whatever magic they made for OS4 into the Linux-kernel?

And what exactly is "goodtime.avi"?

The IDE driver is still very unoptimised.

Performance is between 20-30 MB/s on average.

The benchmark program is 68K being emulated however.

Ok. Thanks for the info.

To get the DMA to work perfectly on A1 is as important as the whole AOS release for A1, in my opinnion.

UPDATE: Beers withdrawn to a better time & moment. :-|



Now.... another problem ..... how could I any more motivate myself to try to fix the 9Mb/sec SCSI kit of my A4k ....

@Hyperionmp

Congratulations, guys. This is very good news.

Will the DMA capable a1ide device make it into the pre-release?

@mjohnson

It's a music video that's included on the install CD for Windows 95

An emulated 020 i see, is it possible to choose which cpu to emulate ?.

So what!?

My A1 with Debian does not even reach 20MB/s....

What would be the point? The 040 and 060 have LESS commands than the 020, and if the emulator supports all 020 commands, it might as well identify itself as an 020. Opting to choose "040" or "060" wouldn't make the emulator itself any faster.

That is simply not true!! The 040 and 060 have alot FPU and MMU commands that the 020 dont have. The 020 have 2 opcodes (CALLM, RTM) that none of the other cpus have but they are not used and proberly not even emulated by OS4.

What DMA mode (mdma(0|1|2), udma(0|1|2|3|4|5) is/was being used?

@RWO

Hmmm.. maybe i'm wrong... it certainly wouldn't be the first time. I thought some of the bitfield ops were emulated on the 040 and 060, but its been a loooong time since i looked into the differences.

For the point of choice, i like choices :).

There are some instructions that are emulated on the 040 and 060 as the CPU instruction set doesn't include them. I don't think it makes the slightest bit of difference what the emulator reports itself as, but it makes sense to specify the most compatible CPU (ie. 020 or 030). As there is no MMU emulation AFAIK, then 68020 is more sensible as some 68030 detection code may assume a 68030 has an MMU.
