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 137 of 228 | ANN.lu |
Posted by Fabio Alemagna on 09-Jun-2004 16:49 GMT | In reply to Comment 133 (Stefan Burström): Ok, given those facts, other questions come to my mind.
For example: how does the loader know it has to open the wrapper library instead of the real one? It's an idiotic question, I know, but I just want to get everything straight. Of course the obvious answer is that when the loader recognizes the library is 68k, it tries to open the stub library.
However... what happens if the code that is calling OpenLibrary() is 68k? Of course the loader doesn't have to open the stub library. Is this right?
If so, how does the loader know that it's being called by 68k code? Is there a special version of OpenLibrary/OpenDevice for 68k code only? And, regardless of this, how does one deal with the case in which the 68k code returns the library base to the PPC code, for it to use? This 68k code could be a library, and a function of this library could be returning the pointer to another library, for whatever reason. How's this dealt with? |
