OpenBeOS floppy driver

This morning at 6 am I succesfully transfered the first file from a 
floppy using the OpenBeOS floppy driver :) (and fell on the bed just 
after)

It's slow as hell for now as I transfer each sector at once, but it 
works.
I currently use the PIO mode, and I think if I get it fast enough we 
might 
be able to drop ISA DMA support from the isa bus manager, since it's 
only 
used for that it seems.
It already supports 720K floppies and double drives, which the R5 
driver
doesn't know about.

It should appear in the cvs RSN.

François.

That sounds really great, François! :-)

Bye,

Btw Axel, this one is for you

:)))

Actually Amiga floppy support is nearly impossible with PC FDC, since 
they don't seem use the same track format...
AFR.C in this zip tells a bit about it.

Actually, there is a solution, which involves the use of a second floppy drive, but can't remember right now.

Actually, I still have an Amiga to do that, so I won't need such a 
thing ;-)

lock.h

There are several drivers and filesystems that make use of a file 
called lock.h, which defines nothing more than a benaphore struct and 4 
kernel exports. Instead of copying this file everywhere, ould we have 
it public ? Btw, there is a 
current/headers/private/kernel/lock.h
which doesn't define the same API, as it comes from NewOS.

François.

Yes, I thought about "melting" them to one file. I guess we have to 
export the functions anyway, although I'd check first if the mlock 
stuff is used anyway (looks very superficial to me).
AFAICT only the PCMCIA bus manager and the NTFS file system add-ons are 
using it, so I'd say that we should try to remove them first, if only 
in the headers.
I also think we should change the LOCK() and UNLOCK() macros to static 
inline functions and rename them to acquire_lock() and release_lock().
We should just replace our benaphore_*() stuff in the lock header with 
those functions, in order to keep the kernel as clean as possible.

Bye,
   Axel.

yeah... m = minimalistic ?

They are at least used by the NFS client too.
But we have the source for this one.

Dunno if they thought much at all when introducing these :)

Hm, the CIFS add-on does not, and I don't have a NFS add-on here. Also, 
the file system API will be different, and not compatible, so that's 
not a problem ;)

Okay, I'll add those calls then, and remove the various lock.h - thanks 
for the hint.

Bye,
   Axel.

Build broken

Hello all,

I don't know if this is a known problem, but the build is currently 
broken in libroot. I know
that you are working on this, Axel, so if the compile error is intended
/known, don't worry
then. The message:

KernelLd objects/x86.R1/kernel/init
objects/x86.R1/kernel/libroot.so: undefined reference to `vsnprintf'

        ld  --script=src/kernel/ldscripts/x86/app.ld  -o "objects/

P.S. I hope to have a small surprise ready for christmas!
