src/sys/modules/sio, branch releng/7.0

Rewrite of puc(4). Significant changes are:

2006-04-28T21:21:53Z

o Properly use rman(9) to manage resources. This eliminates the need to puc-specific hacks to rman. It also allows devinfo(8) to be used to find out the specific assignment of resources to serial/parallel ports. o Compress the PCI device "database" by optimizing for the common case and to use a procedural interface to handle the exceptions. The procedural interface also generalizes the need to setup the hardware (program chipsets, program clock frequencies). o Eliminate the need for PUC_FASTINTR. Serdev devices are fast by default and non-serdev devices are handled by the bus. o Use the serdev I/F to collect interrupt status and to handle interrupts across ports in priority order. o Sync the PCI device configuration to include devices found in NetBSD and not yet merged to FreeBSD. o Add support for Quatech 2, 4 and 8 port UARTs. o Add support for a couple dozen Timedia serial cards as found in Linux.

Let modules use the kernel's opt_*.h files if built along with

2005-10-14T23:30:17Z

the kernel by wrapping all targets for fake opt_*.h files in .if defined(KERNBUILDDIR). Thus, such fake files won't be created at all if modules are built with the kernel. Some modules undergo cleanup like removing unused or unneeded options or .h files, without which they wouldn't build this way or the other.

Change a directory layout for pc98.

o Remove opt_ddb.h from SRCS.

o Add opt_gdb.h and opt_kdb.h to SRCS.

Move to generating pccarddevs.h on the fly, both for the kernel and

the modules. Also generate usbdevs.h automatically now, but a non-kernel file is stopping that at the moment.

Remove the source file for the sio(4) EBus attachment here, too.

Fixed some style bugs:

2003-12-29T08:45:38Z

- SRCS was totally disordered. - the echos to create options headers were hidden using '@'. - the args of echos to create options headers were single-quoted. - the target names for the rules to create options headers were repeated. - the unused option COMPAT_FREEBSD4 was put in opt_compat.h.

Fixed some style bugs. SRCS and the opt_*.h rules were totally

disordered. This commit only fixes the external disorder by rearranging whole lines.

Fix to support pc98 and currect typo.

New sio module. A number of people have suggested this over the years

(most recently bde), so I'll commit the module I've had knocking around in my tree for a while. This may have some rough edges, so if you are able to build it on non-i386 platform (including pc98) please let me know you succeeded. When I get enough reports, I'll connect it to the build. If there are problems, feel free to fix them. Suggested by: bde
