To compile parallel port support as a module, choose M here: 34 the module will be called parport. 35 If you have more than one parallel port and want to specify which 36 port and IRQ to be used by this driver at module load time, take a 37 look at <file:Documentation/admin-guide/parport.rst>. 38 39 If unsure, say Y. 40 41if PARPORT 42 43config PARPORT_PC 44 tristate "PC-style hardware" 45 depends on ARCH_MIGHT_HAVE_PC_PARPORT || PCI 46 depends on HAS_IOPORT 47 help 48 You should say Y here if you have a PC-style parallel port. All 49 IBM PC compatible computers and some Alphas have PC-style 50 parallel ports. PA-RISC owners should only say Y here if they 51 have a SuperIO parallel port. 52 53 To compile this driver as a module, choose M here: the 54 module will be called parport_pc. 55 56 If unsure, say Y. 57 58config PARPORT_SERIAL 59 tristate "Multi-IO cards (parallel and serial)" 60 depends on SERIAL_8250_PCI && PARPORT_PC && PCI 61 help 62 This adds support for multi-IO PCI cards that have parallel and 63 serial ports. You should say Y or M here. If you say M, the module 64 will be called parport_serial. 65 66config PARPORT_PC_FIFO 67 bool "Use FIFO/DMA if available" 68 depends on PARPORT_PC 69 help 70 Many parallel port chipsets provide hardware that can speed up 71 printing. Say Y here if you want to take advantage of that. 72 73 As well as actually having a FIFO, or DMA capability, the kernel 74 will need to know which IRQ the parallel port has. By default, 75 parallel port interrupts will not be used, and so neither will the 76 FIFO. See <file:Documentation/admin-guide/parport.rst> to find out how to 77 specify which IRQ/DMA to use. 78 79config PARPORT_PC_SUPERIO 80 bool "SuperIO chipset support" 81 depends on ARCH_MIGHT_HAVE_PC_PARPORT && PARPORT_PC && !PARISC 82 help 83 Saying Y here enables some probes for Super-IO chipsets in order to 84 find out things like base addresses, IRQ lines and DMA channels. It 85 is safe to say N. 86 87config PARPORT_PC_PCMCIA 88 tristate "Support for PCMCIA management for PC-style ports" 89 depends on PCMCIA && PARPORT_PC 90 help 91 Say Y here if you need PCMCIA support for your PC-style parallel 92 ports. If unsure, say N. 93 94config PARPORT_IP32 95 tristate "SGI IP32 builtin port" 96 depends on SGI_IP32 97 select PARPORT_NOT_PC 98 help 99 Say Y here if you need support for the parallel port on 100 SGI O2 machines. This code is also available as a module (say M), 101 called parport_ip32. If in doubt, saying N is the safe plan. 102 103config PARPORT_AMIGA 104 tristate "Amiga builtin port" 105 depends on AMIGA 106 select PARPORT_NOT_PC 107 help 108 Say Y here if you need support for the parallel port hardware on 109 Amiga machines. This code is also available as a module (say M), 110 called parport_amiga. If in doubt, saying N is the safe plan. 111 112config PARPORT_MFC3 113 tristate "Multiface III parallel port" 114 depends on ZORRO 115 select PARPORT_NOT_PC 116 help 117 Say Y here if you need parallel port support for the MFC3 card. 118 This code is also available as a module (say M), called 119 parport_mfc3. If in doubt, saying N is the safe plan. 120 121config PARPORT_ATARI 122 tristate "Atari hardware" 123 depends on ATARI 124 select PARPORT_NOT_PC 125 help 126 Say Y here if you need support for the parallel port hardware on 127 Atari machines. This code is also available as a module (say M), 128 called parport_atari. If in doubt, saying N is the safe plan. 129 130config PARPORT_GSC 131 tristate 132 default GSC 133 select PARPORT_NOT_PC 134 135config PARPORT_SUNBPP 136 tristate "Sparc hardware" 137 depends on SBUS 138 select PARPORT_NOT_PC 139 help 140 This driver provides support for the bidirectional parallel port 141 found on many Sun machines. Note that many of the newer Ultras 142 actually have pc style hardware instead. 143 144config PARPORT_1284 145 bool "IEEE 1284 transfer modes" 146 help 147 If you have a printer that supports status readback or device ID, or 148 want to use a device that uses enhanced parallel port transfer modes 149 such as EPP and ECP, say Y here to enable advanced IEEE 1284 150 transfer modes. Also say Y if you want device ID information to 151 appear in /proc/sys/dev/parport/*/autoprobe*. It is safe to say N. 152 153config PARPORT_NOT_PC 154 bool 155 156endif # PARPORT 157
