Novacoder made this comment on EAB regarding Quake2;
Quote:
Although it's always nice to see my AGA ports running on Vampire I don't really think they are a good fit for more modern hardware. My old ports were created to get the best out of AGA but the Vampire V4 could support OpenGL with hardware support in 16 bit color....that would make things much more exciting |

Unsure about the resolution. I have Tuko on watchlist on youtube, and noticed this upload. |

honestly these people running Quake 2 in such low resolutions. One should always run this game in full 1920x1080 HD mode like I do on the X5000 It moves like a rocket!!
Saying that I was impressed with the version of Quake I that was running on the Vampire accelerated A600 at Amiga 32

basic 3d acceleration is enough to delegate guake gl rendering to a graphic card. resolution doesnt play any much role ba then you can go as far as the card delivers. software rasterizer along with color reduction and chunky to planar as in case amiga/vampire aga version should be much more costly on a cpu.

ah ok. this change something the speed is near a 604e 233 with permedia 2 on warpos with gl but at 400x300
here there is my old tutorial where you can see the 26 fps on 604e 233 warpos with cybervisionppc . http://www.amigazette.org/numero_09/morphos.html the other shot was same machine with morphos Last edited by tlosm on 31-Oct-2017 at 06:58 PM.

| Gunnar made a general comment about the direction and intent of the Apollo core, which will adress relatively frequently asked questions;
Quote:
Is was always clear that: APOLLO's roadmap includes to run everything any 68K can run. This means also including running Linux. But we have a clear policy about future features: We _NEVER_ promise the users features that are not available today but only on our roadmap. Users always only guarantee stuff working today 100%. This means even if we might even run internally Linux for testing. As long we are not sure we can release it now. Our official answer will always be "no you can not run Linux". |

Once the core is fully featured, someone will make a Linux distro for it, it's just inevitable. It'll probably be awesome to run Linux-Libre systems on this.
But as with everything in technology, patience is a virtue. |

| And Gunnar has had 2 cups of coffe today it seems. He decided to go into more details about the MMU mechanics of legacy and Apollo;
http://www.apollo-core.com/knowledge.php?b=4¬e=11026&z=U8rPdR
Quote:
The MMU topic seems to be confusing.
Lets us try to explain it.
An MMU is a piece of logic which allows to do three things. a) It allows to map blocks of memory to another address. A typical used block size is 4 KB. Modern MMU also support bigger blocks e.g 64KB or 1MB. Support for bigger blocks gives for some applications advantages.
b) the MMU allows to control cache setting for blocks.
c) The MMu allows to write/protect memory
APOLLO 68080 has a build in MMU.
Where is the difference between APOLLO and previous 68K CPUs?
Previous 68K CPUs did NOT come with a memory controller inside the CPU. This means the memory access logic, the memory layout and control of this was always done OUTSIDE of the CPU. This means while the CPU could inside change their logical view of the addresses with the MMU - it did not have any understanding of how this is mapped outside - as this understanding was controlled by the mainboard chips of the system.
Also the other way around - if the mainboard chips did do some DMA access - they could not know how these areas are mapped inside the CPU MMU.
This old concept did create many problems. You all have seen those on the AMIGA.
DMA channels on the AMIGA did always work on physical address. While programs would work on virtual addresses. This mismatch was not solvable on AMIGA. If an application was requesting DMA and was using its virtual view of addresses this was leading to crashes.
APOLLO fixes this problem.
APOLLO has the SAGA DMA channels inside the CPU core. This means both DMA and CPU can use the same representation of the world. This does solve a number of old problems. The CPU does see automatically if DMA channels update memory which is cached by the CPU caches. This means the CPU has always a coherent view of the memory. This solves many old DMA issues and also allow the usage of APOLLO with many CPU cores. All CPU cores and the DMA engines share one coherent view of the world.
Another big difference to old 68K CPUs is that old 68K CPUs did only support 1 bus.
APOLLO is designed as a system supporting several memory controllers.
Old MMUs did had a linear address view in 1 dimension. APOLLO has a multidimensional view.
All these concepts which APOLLO offers are new to the 68K world. These concepts do exist already today in other enterprise systems.
Coherent multi core systems supporting several memory channels or memory hierarchies are state of the art today. Apollo is from ground up designed to support this too.
AMIGA OS is not designed for this today. AMIGA OS can not easily use SMP. AMIGA OS can not control NUMA memory views.
To provide a old fashioned 1 dimensional memory view to old AMIGA MMU applications - a clean solution would be to provide an sub MMU with 1 dimension inside the multidimensional MMU view.
This feature would transparently support old applications. This can be done but is _NOT_ in planned for any releases coming soon. |

Seems to me that the Apollo core would allow for back-porting of 4.1 to 68k... ;) |

apollo multicore ?? if it can be implanted in the 680x0 what about the amiga os. wasn't there a multicore aros in the works ???
so how much os 3.x compatible is aros ?
or could an warp os jit thing be done ? |

from what I understand of the design is that it's trivial to make Apollo a multi-core 68k processor, there was talks of this back in the Natami days... |

but can it be used for us, and what benefit would it be to use power to simulate a multicore insted of using more power for at single core.. also was there not talk about and coldfire fpga core some time ago ?? was there a multicore coldfire cpu build back in the days |

Not sure, I don't own the game nor does it appear to be out for Amiga OS4 or 68K RTG. I notice it is out for Aros only, so I am guessing that's why you are bigging it up 
Personally i like Doom on the Xbox One rather than playing the original versions.
Whilst we are on the topic of how things are running, how about you let us know any updates to the ever elusive Final Writer as I believe you are the fine gentleman responsible for the update?

Because it is technically impossible to get more power out of 1 core ? Why are other cpu venders have so many cores instead of 1 superfast one. |

You have misunderstood the concept of hyperthreading. Quote:
With HTT, one physical core appears as two processors to the operating system, allowing concurrent scheduling of two processes per core. ...In addition to requiring simultaneous multithreading (SMT) support in the operating system, hyper-threading can be properly utilized only with an operating system specifically optimized for it. |
If the OS can't handle more than one core, then it can't handle hyper threading, either.Last edited by simplex on 18-Nov-2017 at 01:13 AM. Last edited by simplex on 18-Nov-2017 at 01:12 AM.
