* Return the port size from the probe.Peter Wemm1999-04-221-2/+3
| | | | | | | | "ppc0 at port 0x378 irq 7 drq 3 on isa0" becomes "ppc0 at port 0x378-0x37f irq 7 drq 3 on isa0" Notes: svn path=/head/; revision=45935

* Distinguish EPP address/data register. Add EPP address register access to ppi.Nicolas Souchu1999-01-302-18/+19
| | | | | | | | | | | Change microseq offsets. Previously, offsets of the program counter where added to the index of the current microinstruction. Make them rely on the index of the next executed microinstruction. Suggested by: Luigi Rizzo <luigi@labinfo.iet.unipi.it> Notes: svn path=/head/; revision=43433

* Major ppbus commit with:Nicolas Souchu1999-01-102-52/+486
| | | | | | | | | | | | | | | | | | | | | | + 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.

* Major ppbus updates from the author.Mike Smith1998-08-032-190/+609
| | | | | | | | | | | | | | | | | | | | - 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.
