This has nothing to do with compatibility.
Sorry Markus but I do not understand your "joke?" :-)

As you know Apollo 68080 is a new improved CPU.
Apollo 68080 re-added all the instruction which are missing on 68060.
Apollo 68080 executes bitfield instructions 10 times faster than 68060.
Apollo 68080 can execute many instruction super scalar which the 68060 can not - simple example : 2 SWAP per clock.

Apollo is not an 68060 and does not try to mimick it.
Apollo has in theory 3 CPU pipes and could in theory execute up to 6 instructions per cycle - but in the Vampire we do not use the 3rd pipe as we measured that existing AMIGA software does benefit very little of this width.

APOLLO has a number of switches which allows us to enable pipelines, configure the Cache size etc. And if we in some core version enable some paranoia checks then its this way in this core version.

  You just made me really curious. What's that?
 

 
  If you want to execute many instructions per cycle then use this code
 
 

  MOVE.L D0,D1
  ADD.L  D2,D1
  MOVE.L D0,D4
  ADD.L  D3,D4
 

  With this code Apollo will give an IPC of 4
 
 
  The Paranioa check forbids executing with cross operants.
 

  move.l D0,D1
  move.l D1,D0
 

  This check can be disabled then the code will execute with IPC=2
 

Is it possible to have a code that broke the pipeline in all case (68060, 68080 with any option) to have only one instruction per cycle?

Yes, use code where each instruction is depending of the result of the previous.
 
Example:

ADD.L D0,D1
ADD.L D0,D1
ADD.L D0,D1
ADD.L D0,D1
ADD.L D0,D1
ADD.L D0,D1
ADD.L D0,D1
ADD.L D0,D1
ADD.L D0,D1
ADD.L D0,D1

Thanks Gunnar, I'm going to update frequency check, it will better like this.

  Currently, Amiga partitions are completely unsupported by EmuTOS. You need a dedicated mass storage (CompactFlash or IDE hard disk) formatted in PC way with a FAT16 partition. Additionally, FreeMiNT also supports FAT32 and ext partitions.
 

 
  Has anything changed on Atari side of Vampire?
 
  I see there is some support in EmuTOS
 
  Release 0.9.7:[9] support for extended MBR partitions, MonSTer board, Eiffel on CAN bus on ColdFire EVB and Apollo Core 68080. FreeMiNT
 
  However in lastest FreeMINT I see just these CPUs listed

  The different FreeMiNT kernels. Place the right kernel for
  your hardware in the AUTO folder of your boot drive. Please see in the
  release notes for more details.
 
 
  mint000.prg - kernel for 68000 CPU based ATARI's
 
                --> ATARI ST/STE
                --> MEGA ST/STE
 
  mint030.prg - kernel for 68030 CPU based ATARI's
 
                --> ATARI TT
                --> ATARI Falcon
                --> 68030 based accelerators (CT2, PAK/30)
 
  mint040.prg - kernel for 68040 CPU based ATARI's
 
                --> Falcon with Afterburner

  mint060.prg - kernel for 68060 CPU based ATARI's
 
                --> Falcon with CT60
                --> Hades 060
 
  mint117.prg - kernel for 68020-68060 generic CPU based ATARI's.
 
  mintmil.prg - kernel for Milan computer
 
                --> Milan
                --> Milan with 68060 CPU
 
  mintara.prg - kernel for Aranym generic ATARI emulator
 
  mintdeb.prg - kernel for Debugging.
 
  mintv4e.prg - kernel for Freescale ColdFire v4e processor systems.

If you are unfamiliar to Atari ST Operating Systems, you can have a look at my foss-north 2018 presentation. You will learn many things about EmuTOS, FreeMiNT, and much more. Subtitles will be available soon.

This is nice, this slides shows our Amiga friends how the Tos and Mint Works or is made. Tried to explain it already but this is more understandable.

Regards

Ingo

Vincent, you are great!
Thank you for all your contributions in Atari community!
Tis video is also great and I believe very valuable to Atmiga community to understand Atari computers/community.

Thank you Vincent. Very informative, long road to go.

Slides are very nice

I think this is also something we have to discuss in the Atari community. Amitari looks nice and promising. There is also Easyaramint package which looks nice in Aranym, but it is not updated since long time. But EasyMiNT for real Atari is stopped and makes the feeling as it is incomplete on application side. I want to be able to install Amitari on my CT60e tuned Falcon... Or EasyAramint, or a good mixture of both, on my TT and having a set of applications and games which run out of the box. I think the future MiNT distribution must not be fixed on a hardware plattform, it musgt be possible to install the same environement on original (powerfull, tuned) Atari hardware, in emulator and 'new' hardware like TOS infected Amiga, Vampireized Amiga and ST, Firebee, and so on. ANd like Easyaramint already did, comming with a good collection of working applications, well preconfigured.

  Yes, looks a bit fragemented to non-informed eye, and hope some set of standard will be set. Best, one app set with executables for few platforms or CPUs (00/030/040/060/FB/AC080) where rest of drivers could be selected/autodetected.
 
  Also, another Amitari question is when PFS/FFS/SFS will be fully supported at least accesable from FAT16/Ext2 EmuTOS partition, if not best, installable there also.
 
  In the end, MINT is so flexibile it requires a directory only and  since emuTOS will be part of Vampire -  it could even reside next to AmigaOS.

These are really nice advancements, fully using Vamps faster IDE, ability to change ROMs (hence EmuTOS) and native mouse. VIDEL driver, Paula driver, Net driver ... and beat goes on :)

Will there be plans in the future to support 4'IEDE'99 Buffer for EmuTOS to detect the hardware?

Greetings back to the Amiga Site of live ^^ .. thinks are going on well. Step by Step we are getting closer to get a pretty nice system.
Only possible with your great help Vampmigan Friends :)
