Kernel 2.4 rots

[Frank R. G. P. <pe...@he...>]

It seems that the more recent the APUS kernel version, the less of my
hardware works. The kernel with most HW working was some 2.2 version. With
the current 2.4.x, the parallel port is completely broken, so the printer
is useless. The serial port hangs when there is access to the IDE harddisk.
The Multiface board driver is not compilable anymore. So, this is a hard
time for people who want to do I/O other than display on an A4k with APUS.

I remember the parallel port driver being broken in the 2.2 times. Somebody
fixed it in just a few lines. Now exactly the same broken behaviour shows
in the current 2.4 tree. Who fixed the 2.2 driver? How? I had a shot with 
inserting io barriers and even delays, but no go.

It seems that the Amiga 4000 has to be removed of the list of supported HW in
linux/APUS. Or does any of the A1200 have these problems? Or does nobody want
to print or use the serial port? Internet, anyone?

It's great that you tried to do something. Don't give up now!

I don't expect things to be any better there.

IMO the problem is that nobody really cares about 2.4 yet. The users thin=
k
it's beta or unstable or whatever (what is our 2.2 kernel then?) and the
developers still work on 2.2 . We really must concentrate on 2.4 _now_ an=
d fix
the problems it has.

Hmm, I have an Amiga4000 and I use the serial port mostly for debugging,
beside of this I mostly connect to it over ethernet, so the most important
driver for me is the ariadne2 driver and that works fine. :)
Anyway, keeping the 2.4 apus tree uptodate is only one of my interests,
I'm doing for _fun_, so please don't expect that I'm overly stress myself.
On the other hand I'm quite willing to answer any questions about kernel
programming, so anyone with some basic C knowledge can help to fix the
existing problems. We're only a small community, so you have to do a bit
yourself and you can't expect everything is done for you.
BTW you can also ask on the linux-m68k list, to find out whether some
problems are general or ppc related.

bye, Roman

how close an eye is being kept on the m68k 2.4.x work being done?
I've seen quite a lot of fixes going into that tree... any of them help
APUS 2.4?

Most of the stuff I've seen lately seems to be m68k specific. I once
integrated a fix for BlizzardPPC etc. SCSI drivers, but it looks like Gee=
rt
manages to get the m68k stuff into Linus' tree rather quickly and thus in=
to
the APUS tree anyway. :)
