* Port of ppbus standalone framework to the newbus system.nsouch2000-01-141-6/+10
| | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | + 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.

- ppbus now supports PLIP via the if_plip driver - ieee1284 infrastructure added, including parallel-port PnP - port microsequencer added, for scripting the sort of port I/O that is common with parallel devices without endless calls up and down through the driver structure. - improved bus ownership behaviour among the ppbus-using drivers. - improved I/O chipset feature detection The vpo driver is now implemented using the microsequencer, leading to some performance improvements as well as providing an extensive example of its use.
