Library reference counts are incremented and decremented in Forbid() state. But your point still remains valid. For example Intuition supports manipulating window flags directly but underlines you must use atomic instructions. Applications also depend on atomic instructions in their internal threading.
However, when you are not emulating OS but running our own OS natively you can take this into account and have a hidden dupe field for internal system flags etc. etc.

A 68k emulator should emulate a 68k. That includes making the same guarantees. The only way to do that with a task-based 68k->PPC emulator is to call Forbid()/Permit() (or Disable()/Enable()) for every single emulated 68k instruction that executes more than one memory access.
|
Calling Forbid() would not be enough because atomic instructions can't be interrupted by, eh, interrupts. It would be mandatory to call Disable() for every instruction. But those cases are really rare and only very few modern applications rely on atomic instructions (mostly those written in machine language or using machine language macros) and (as I wrote above) you can also take it into account in the OS level.
FORBID macro advertised by Commodore system developers is quite nasty, though Last edited by itix on 04-Sep-2011 at 08:08 PM. Last edited by itix on 04-Sep-2011 at 08:05 PM. Last edited by itix on 04-Sep-2011 at 08:04 PM.

Take the old classic "ADDQ.B #1,TDNestCnt(A6)", which was compiled inline into plenty of 68k code, because that's one of many such macros in include_i/exec/ables.i[1]. |
While you make a good case for what would trap the emulator and possibly the reason some 68K games and software freeze upon loading it must be said that code doing things like Forbid() ASM MACROS directly is definately not supported in OS4.
Only code using the actual Forbid() function would be supported and even then going out on a limb as software employing such techniques as disabling multitasking would be warned against. OS4 with its 68K emulation integrates to a high degree 68K software; perhaps too high, as a rogue Forbid() will halt the entire system. Unless it waits. And 68K interupts are actually executed in an actual real PPC interupt. I thinks they've made that too close to the system there. |

| I hope there have some betatester test the blender benchmark and see the real speed of the pa6.
http://www.eofw.org/bench/
there are several other MOS or OS4 Systems to compare.
If somebody tell its slow because driver for X1000 are not optimize or so, look at the sourcecode of blender when execute this benchmark code, if you not believe that Raytracing execute 99.9 % own code, so OS or driver speed doesnt matter in performance with this benchmark

| Is there anyway of telling how many Beta Testers received their boards?
I would think there would be a lot of YouTUBE videos up by now.

I think you missed something, I'll remind you of it just for your convenience (and avoid you searching just one post above):

i presonally know about 2 betatesters that received boards, and both confirmed that publishing photos of their boards is not restricted by nda. both have put a lot of snapshots online. i trust there is more borads delivered, just not everybody is doing that much fuss. f.i. here: http://www.a1k.org/forum/showthread.php?t=28870 |

Pictures of the boards and even videos of the manufacturing process have been already published, so I don't see any problem with that. But people want to see now benchmarks and videos of AOS 4 and software running on it, which is what I think would be under NDA. _________________ PowerBook 5.2 MorphOS 3.15 PowerBook 5.8 MorphOS 3.15 Amiga 1200 BPPC/BVision AOS4.1 FE |

yes apparently nothing what concerns os4.1 on x1k may be spilled. the user above reports the speed of the system as "insane", of course not backing it up by anything, and im not sure if he ever owned any ng os4 system. thoght his comments are very entusiastic (as they ever were) so there is no major letdown, it seems. |

bernd this is all fine and right but i dont think anybody will provide results openly at this time. |

| Since the OS is in beta, I don't see why there should be any need for benchmarks, since the system isn't fully optimised and therefore would probably be running slower than it otherwise would. And all that would achieve is to trigger another round of those very helpful posts, saying how it should be faster for that price, etc. etc.
I can post a screenshot of 4.1 running on my A1, it'll pretty much look the same as 4.1 running on an X1000 - I don't see the point in that. It's like comparing screenshots of Windows 7 running on a Sony Viao to Windows 7 running on an Alienware machine. Nonetheless, I'm sure the betatesters will post pictures in due course. _________________ RobTheNerd.com | InstallerGen | SMBMounter | Atoms-X |

The user quoted by wawa, is long term AmigaOS user. He used to have SAM (Flex I think). He also owns a fast A1200 running OS4.1upd 3. However, I would consider him as very enthusiastic.... and if says it is insane fast, he means it is insane fast. He knows fast Systems very well from e.g. Amiganoid, where we had an AmigaOne G4 XE 1,266 Ghz OS 4.1.
Fair enough they are not allowed to post benchmarks, remember the endless discussion going on about the slow bootprocess, as Videos had been published by AmigaKit...
