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 115 of 228 | ANN.lu |
Posted by RiVA Author on 09-Jun-2004 15:02 GMT | In reply to Comment 107 (Fabio Alemagna): "I would like to hear the rationale behind the interface thing."
The main reason IMHO is to allow a library API to evolve. For instance at the moment dos.library does not support seeking in files larger than 2MB, because the seek offset is 32bit in the Seek function's parameters. With the new library system, you can define a completely new and clean interface, which has a new Seek() command that takes 64bit parameters, for instance. The old software will get the old interface (backward compatibility), the new software can use the new interface. If you use the old-style library design you would have to define functions like NewSeek() etc. I hope you're beginning to see the point... (unless you just don't want to see it :) |
