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 124 of 228 | ANN.lu |

Hmm... ok, so I got it wrong before (which however means that now other things are not clear). So let me get this straight: if I have a PPC program that needs to use a 68k library, I need to write/autogenerate certain stub code that gets linked with the program. Is this correct?

Now, that is what I got wrong too: there still are stubs, since they are linked with the program. Right?

Now, this I don't understand. What does it really mean? How can it become the replacement for something that is linked with the program at compile time? |
