* Some newbus-inspired tidy-ups. Use device_identify() rather than scanningpeter2000-01-231-36/+34
| | | | | | | | | | | | the resource table to locate children. The 'at ppbus?' can go again. Remove a few #if Nxxx > 0' type things, config arranges this for us. Move the newbus method glue next to the DRIVER_MODULE() stuff so we don't need extra prototypes. Don't set device descriptions until after the possibility of the probe returning an error. Remove all cdevsw_add() calls, all the drivers that did this also use make_dev() correctly, so it's not required. A couple of other minor nits.
* Port of ppbus standalone framework to the newbus system.nsouch2000-01-141-117/+45
| | | | | | | | | | | | | | | | | | | | | Note1: the correct interrupt level is invoked correctly for each driver. For this purpose, drivers request the bus before being able to call BUS_SETUP_INTR and BUS_TEARDOWN_INTR call is forced by the ppbus core when drivers release it. Thus, when BUS_SETUP_INTR is called at ppbus driver level, ppbus checks that the caller owns the bus and stores the interrupt handler cookie (in order to unregister it later). Printing is impossible while plip link is up is still TRUE. vpo (ZIP driver) and lpt are make in such a way that using the ZIP and printing concurrently is permitted is also TRUE. Note2: specific chipset detection is not done by default. PPC_PROBE_CHIPSET is now needed to force chipset detection. If set, the flags 0x40 still avoid detection at boot. Port of the pcf(4) driver to the newbus system (was previously directly connected to the rootbus and attached by a bogus pcf_isa_probe function).
* Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"peter1999-12-291-2/+2
| | | | | | is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.
* Remove the 'ivars' arguement to device_add_child() andmdodd1999-12-031-2/+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

* Alter the behavior of sys/kern/subr_bus.c:device_print_child()mdodd1999-07-291-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

| | | | | | | | | | | | | | | | | | | + ECP parallel port chipset FIFO detection + DMA+FIFO parallel I/O handled as chipset specific + nlpt updated in order to use the above enhanced parallel I/O. Use 'lptcontrol -e' to use enhanced I/O + Various options documented in LINT + Full IEEE1284 NIBBLE and BYTE modes support. See ppbus(4) for an overview of the IEEE1284 standard + Detection of PnP parallel devices at boot + Read capability added to nlpt driver to get IEEE1284 compliant printer status with a simple 'cat /dev/lpt0' + IEEE1284 peripheral emulation added to BYTE mode. Two computers may dialog according to IEEE1284 signaling method. See PERIPH_1284 option and /sys/dev/ppbus/ppi.c All this code is supposed to provide basic functions for IEEE1284 programming. ppi.c and nlpt.c may act as examples.
