* Add a truely evil workaround (hack!) for some unfortunate BIOSpeter1999-12-061-6/+23
| | | | | | | | | | | programming practices. It seems that newer fdc chips have an alternative way of setting the transfer speed (including high speed modes for floppy tape) that doesn't use the control register (which we don't support - we use the old way only). So, they (the BIOS programmers) sometimes leave out the 0x3f6 control register from the PnP ports descriptor(!!). "Hey, it works with windows, so what's the problem?" :-( Anyway, this hack tries to compensate for that. This was discussed with dfr (who did the pnp attachment).
* Remove the 'ivars' arguement to device_add_child() andmdodd1999-12-031-1/+2
| | | | | | | | | | | | | | | | device_add_child_ordered(). 'ivars' may now be set using the device_set_ivars() function. This makes it easier for us to change how arbitrary data structures are associated with a device_t. Eventually we won't be modifying device_t to add additional pointers for ivars, softc data etc. Despite my best efforts I've probably forgotten something so let me know if this breaks anything. I've been running with this change for months and its been quite involved actually isolating all the changes from the rest of the local changes in my tree. Reviewed by: peter, dfr
* Tidy up a few loose ends in the fifo setup code.peter1999-11-181-20/+1
| | | | | | Don't use NFDC as an arbitary limit, it is not required and goes against using PnP fdc devices (eg: when PNPBIOS is turned on, the motherboard devices (sio, fdc, etc etc) are detected via PnP, not config(8).)

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers) Add the correct hook for devfs to kern_conf.c The net result of this excercise is that a lot less files depends on DEVFS, and devtoname() gets more sensible output in many cases. A few drivers had minor additional cleanups performed relating to cdevsw registration. A few drivers don't register a cdevsw{} anymore, but only use make_dev().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - device_print_child() either lets the BUS_PRINT_CHILD method produce the entire device announcement message or it prints "foo0: not found\n" Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on the previous behavior of device_print_child() (printing the "foo0: <FooDevice 1.1>" bit of the announce message.) Provide bus_print_child_header() and bus_print_child_footer() to actually print the output for bus_generic_print_child(). These functions should be used whenever possible (unless you can just use bus_generic_print_child()) The BUS_PRINT_CHILD method now returns int instead of void. Modify everything else that defines or uses a BUS_PRINT_CHILD method to comply with the above changes. - Devices are 'on' a bus, not 'at' it. - If a custom BUS_PRINT_CHILD method does the same thing as bus_generic_print_child(), use bus_generic_print_child() - Use device_get_nameunit() instead of both device_get_name() and device_get_unit() - All BUS_PRINT_CHILD methods return the number of characters output.

| | | | | | | | | | | | | | | | | | i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA. (Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.) This is a checkpoint of work-in-progress, but is quite functional. The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | peripheral drivers can determine where in the devstat(9) list they are inserted. This requires recompilation of libdevstat, systat, vmstat, rpc.rstatd, and any ports that depend on the devstat code, since the size of the devstat structure has changed. The devstat version number has been incremented as well to reflect the change. This sorts devices in the devstat list in "more interesting" to "less interesting" order. So, for instance, da devices are now more important than floppy drives, and so will appear before floppy drives in the default output from systat, iostat, vmstat, etc. The order of devices is, for now, kept in a central table in devicestat.h. If individual drivers were able to make a meaningful decision on what priority they should be at attach time, we could consider splitting the priority information out into the various drivers. For now, though, they have no way of knowing that, so it's easier to put them in an easy to find table. Also, move the checkversion() call in vmstat(8) to a more logical place. Thanks to Bruce and David O'Brien for suggestions, for reviewing this, and for putting up with the long time it has taken me to commit it. Bruce did object somewhat to the central priority table (he would rather the priorities be distributed in each driver), so his objection is duly noted here. Reviewed by: bde, obrien

| | | | | | | | | | | | | | | | | floppy is used on the toshiba Libretto line of subnotebook computers. It differs from a normal floppy in that you must use PIO rather than DMA to transfer the data. To enable this, you must add options "FDC_YE" to your kernel. I don't have a machine that has a floppy and a pcmcia slot to test to make sure that this doesn't impact normal floppy units, so I've left this as an option. I have ported this to -current and made an attempt to ensure that the indentation conforms to style(9), aka the bruce filter. Reviewed by: nate, markm Submitted by: David Horwitt (dhorwitt@ucsd.edu)
