Hans-Jorg Frieden has posted a detailed status update on the progress of OS4 to Amigaworld.net.
Brief summary:
· Picasso96 and MUI PPC native
· Kernel supports PPC performance monitor and Altivec
· Moovid (released with OS3.9 as "action") is now running native, and can play DivX and other common formats
· GCC 3.4.0 is ported
· The C libraries are much faster. As a result AmiPDF is up to 60 times faster.
· Serial and floppy drivers coming soon
· USB is working and supports HID devices like keyboards and mice as well as HID joysticks and steering wheels, and USB mass storage devices like USB sticks, flash card readers, 7-in-1 card readers and cameras
· A1 IDE device now has working UDMA support. Also, interrupts are no longer polled but delivered properly. This means that the device does not require any CPU time for transfers.
This material will in due course be released for download to registered users of the Developer Pre-release on our web site at:

OS4 progress since pre-release : Comment 128 of 228 | ANN.lu |
Posted by Fabio Alemagna on 09-Jun-2004 15:47 GMT | In reply to Comment 122 (Stefan Burström): Oh, forgot one thing:
> When you compile the new library, it will become the replacement for the stub
> library. The original stub library just took care of the register transfers
> to the original m68k library.
If ABI translation is all that those stubs are for, then it follows that the new library doesn't use interfaces?!
If that is now how it is, then you are not explaining things correctly.
The reason I said that is this. Say I have foo.library, which is a 68k library. From my PPC program I call some functions of it, this way:
FooBase = OpenLibrary("foo.library", FOOVERSION);
...
FooFunc1(...);
FooFunc2(...);
...
FooFuncN(...);
...
CloseLibrary(FooBase);
That will work because of the stub functions.
Now, say I port this 68k library to PPC. The above code won't change, because I don't need to recompile the program -> it follows one of the below things:
1) There must be some code which checks whether the library is 68k or not, and thus decide whether to acquire the interface or not, and whether to make the library call trough the interface or not.
2) The PPC library doesn't really need interfaces. |
