src/share/examples/drivers, branch releng/5.0

Modernise and tidy up.

2002-08-02T10:37:22Z

- Modify to make the generated device driver code work with current.

2001-11-13T17:58:14Z

- Use M_ZERO instead of another call to bzero(). Inspired by: misc/31905

pseudo-device -> device in kernel config lines. Removed whitespace at EOL.

Suggest that kernels are built with ``cd /usr/src; make buildkernel''

Add a comment saying that our softc is automatically allocated by the parent bus. Fix lots of spellings

fix spelling errors, clarify comment, add $FreeBSD$

o Add cardbus support (use pci attachment for now)

2000-12-18T21:08:53Z

o Add comments in some places to clarify some points. o Don't typedef sc_p. This isn't usually done in the drivers and may cause problems in teh future if C goes the C++ route of requiring one and only one definition for each and every type. Instead use the current convetion of expanding struct ${1}_softc * inline needed. o change some comments to be more style(9)-like. o Define and use DEV2SOFTC to encapsulate storing/getting softc from a dev_t. This also takes care of the missing cast from the examples. o Define and use DEVICE2SOFTC, similar to DEV2SOFTC for getting the softc from a device_t. We still should have this generate foo_{isa,pci,pccard,cardbus,eisa}.c and foovar.h from templates of some sort, but I was too lazy to do that in this commit. I did document it in the comments, however. Note: bde-like corrections made with the help of my my portable plastic bde icon. Results with the real bde may vary with use.

Slight cleanups after comments from John Hay (Thanks!)

Also add more comments.

Share one devclass between ISA and PCI sections

2000-11-12T10:46:38Z

This will ensure unit numbers will co-ordinate between them

Add basic PCI capability

2000-11-11T09:49:49Z

Not sure how unit numbers are carried across between PCI and ISA though.. maybe there should be only one devclass between the two?

Add more sample code having read the daemnnews article (August 2000)
