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 195 of 228 | ANN.lu |
Posted by Crumb // AAT on 10-Jun-2004 12:30 GMT | In reply to Comment 177 (Alkis Tsapanidis): Then show me a program that uses the MMU and I will invite you to a beer.
I'm still searching that developer docs...
Tell me what things done by MOS can't be done technically by a patched 3.x box or an AROS box. Apart from the ability of running PPC binaries without context changes, that's obvious. And it's also obvious that the native components give better speed. But compare a 68k OS3 with a PPC MOS and tell me what isn't technically possible to achieve. You could recompile easily for 68k 90% of MOS programs and components without doing many changes.
Now... when OS4 gets released and programs like emulators etc start tu use the advanced MMU features, try to port that to your lovely A-Box
MOS at the moment is just an A-Box and 99% of MOS runs inside the A-Box. The Q-Box doesn't even have a driver system. If this wasn't the situation the graphic,ide and other drivers would be inside the Q-BOX and you couldn't overwrite that memory area. So don't tell me fairy tales of magic boxes. At the moment the only "real" box is the only box, the A-Box.
I'm tired of hearing that MOS is "much more". It offers small improvents that could have been done in a 68k system (well, many OS4 components too, BUT the OS4 kernel offers many new features like the MMU stuff I have mentioned).
I own a Pegasos with MOS and yes, it's better than my cyberstormPPC system running OS3.x but it doesn't offer much more that couldn't be done if we forget the slow down of the context changes.
You could port now emulators like MOL to OS4, but it's IMPOSSIBLE to port them to MOS because it doesn't offer any memory management functions that allow you to use the MMU.
Yes, you could do something similar using Thor's MMU library but there's no equivalent in MOS. So.. in the end a 3.x system has some features impossible to do (at least now) in MOS. |
