CVS log for floppy-darwin/MkLinux_floppy/Attic/fd.c

Hooked up format call.  Removed unnecessary old Mach x86 floppy driver
file entirely (so now this code is just an I/O Kit wrapper for a Copland
driver).  Fixed a bug related to valid format capacities for 720k MFM.

First cut at making debugging run-time configurable.  The property
"SWIM3 Debug" can be changed in the plist to turn debugging on before
loading, but in general, the setProperties method should be used to
turn debugging on/off on-the-fly.


dgatwood@mklinux.org

Massive changes for PowerBook support.  Verified both drives work
correctly and independently now.  Need to back-port a plethora of changes
to the MkLinux sources, as it has trouble dealing with simultaneous
floppies as well.


dgatwood@mklinux.org

Turns out the write support issues were a hardware problem.  While
really noisy, this code reads and writes.  Cleanup pending.


dgatwood@mklinux.org

Cleanup of debug messages.


dgatwood@mklinux.org

First cut at read-write support.  Doesn't work yet, probably because
I haven't implemented asynchronous read-write support, but I'm not sure.
It doesn't appear to actually try to read or write anything, which
makes me suspect that it just plain isn't able to wrap synchronous
reads and writes with sleeps and wakeups on its own.  Oh well.  :-)

Wish me luck.


dgatwood@mklinux.org

This should fix a typo.


dgatwood@mklinux.org

Hideously messy stuff.  This was "working" before the latest changes --
it couldn't quite eject, though, because the event was occurring before
the wait.  Moved to semaphores to get preposting behaviour.  Praying.


dgatwood@mklinux.org

Added locking for hardware lock section.  Bloody MkLinux code worked on a
wing and a frigging prayer.  I'm going to fix this in the MkLinux source
when I get done with this.  :-)


dgatwood@mklinux.org

Last cleanup for the night.  Made the use of non_bsd_sleep more correct
and adapted the function to handle sleeps without timeouts.  Now to
fall asleep....


dgatwood@mklinux.org

Major changes to get around lack of the bsd sleep() function.  Wrote my own.


dgatwood@mklinux.org

Major cleanup of compile warnings.  We're down to some crusty stuff in fd.c and a few missing prototypes here and there, mostly for stuff where I'm pretty sure about the  syntax....

Also, made some changes that should cause the OS to probe for media, though I can't test this because I'm not near a machine with SWIM3 hardware at the moment.


dgatwood@mklinux.org

Fixed a NULL pointer dereference in probe code.  Fixed a second NULL pointer dereference caused by temporarily removed code that I'd never reenabled.  Reenabled everything that had been temporarily enabled except for the pieces that have not yet been done (correct sleep/delay behaviour for long sleeps, and add support for read, write, and format).  Changed a bunch of NOTYETDAG ifdefs to IOKITREPLACED or PDMSUPPORT, as appropriate.  For basic support, the only requirements left are the NOTYETDAG items.  Also fixed the arguments so that it can spawn a media scan thread.

dgatwood@mklinux.org

Still more linkage cleanup....

dgatwood@mklinux.org

More linkage cleanup

dgatwood@mklinux.org

Holy crap, some unresolved symbols being fixed in a munging-like fashion.  Yikes, eek, etc.

dgatwood@mklinux.org

Updated pieces.


dgatwood@mklinux.org

Major work on this little puppy.  It took until just now to get it
buildable again.  The fd.c file still needs to be made buildable.

Remaining work:

1.  Make fd.c buildable
2.  Write interface routines to look like block_io() and friends
3.  Write read/write routines
4.  Write interrupt handler pass-thrus to match read/write routines
5.  Write some trivial glue code for dbdma support
6.  Anything else I haven't thought of....


dgatwood@mklinux.org

My pet project.  Working on porting MkLinux's floppy driver to Mac OS X
to support the beige G3 machines, the Wallstreet PowerBook, and any older
machines as appropriate.  This is the first import.  It builds, but does
not actually do anything yet.
