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 && !S390) 46 help 47 You should say Y here if you have a PC-style parallel port. All 48 IBM PC compatible computers and some Alphas have PC-style 49 parallel ports. PA-RISC owners should only say Y here if they 50 have a SuperIO parallel port. 51 52 To compile this driver as a module, choose M here: the 53 module will be called parport_pc. 54 55 If unsure, say Y. 56 57config PARPORT_SERIAL 58 tristate "Multi-IO cards (parallel and serial)" 59 depends on SERIAL_8250_PCI && PARPORT_PC && PCI 60 help 61 This adds support for multi-IO PCI cards that have parallel and 62 serial ports. You should say Y or M here. If you say M, the module 63 will be called parport_serial. 64 65config PARPORT_PC_FIFO 66 bool "Use FIFO/DMA if available" 67 depends on PARPORT_PC 68 help 69 Many parallel port chipsets provide hardware that can speed up 70 printing. Say Y here if you want to take advantage of that. 71 72 As well as actually having a FIFO, or DMA capability, the kernel 73 will need to know which IRQ the parallel port has. By default, 74 parallel port interrupts will not be used, and so neither will the 75 FIFO. See <file:Documentation/admin-guide/parport.rst> to find out how to 76 specify which IRQ/DMA to use. 77 78config PARPORT_PC_SUPERIO 79 bool "SuperIO chipset support" 80 depends on ARCH_MIGHT_HAVE_PC_PARPORT && PARPORT_PC && !PARISC 81 help 82 Saying Y here enables some probes for Super-IO chipsets in order to 83 find out things like base addresses, IRQ lines and DMA channels. It 84 is safe to say N. 85 86config PARPORT_PC_PCMCIA 87 tristate "Support for PCMCIA management for PC-style ports" 88 depends on PCMCIA && PARPORT_PC 89 help 90 Say Y here if you need PCMCIA support for your PC-style parallel 91 ports. If unsure, say N. 92 93config PARPORT_IP32 94 tristate "SGI IP32 builtin port" 95 depends on SGI_IP32 96 select PARPORT_NOT_PC 97 help 98 Say Y here if you need support for the parallel port on 99 SGI O2 machines. This code is also available as a module (say M), 100 called parport_ip32. If in doubt, saying N is the safe plan. 101 102config PARPORT_AMIGA 103 tristate "Amiga builtin port" 104 depends on AMIGA 105 select PARPORT_NOT_PC 106 help 107 Say Y here if you need support for the parallel port hardware on 108 Amiga machines. This code is also available as a module (say M), 109 called parport_amiga. If in doubt, saying N is the safe plan. 110 111config PARPORT_MFC3 112 tristate "Multiface III parallel port" 113 depends on ZORRO 114 select PARPORT_NOT_PC 115 help 116 Say Y here if you need parallel port support for the MFC3 card. 117 This code is also available as a module (say M), called 118 parport_mfc3. If in doubt, saying N is the safe plan. 119 120config PARPORT_ATARI 121 tristate "Atari hardware" 122 depends on ATARI 123 select PARPORT_NOT_PC 124 help 125 Say Y here if you need support for the parallel port hardware on 126 Atari machines. This code is also available as a module (say M), 127 called parport_atari. If in doubt, saying N is the safe plan. 128 129config PARPORT_GSC 130 tristate 131 default GSC 132 select PARPORT_NOT_PC 133 134config PARPORT_SUNBPP 135 tristate "Sparc hardware" 136 depends on SBUS 137 select PARPORT_NOT_PC 138 help 139 This driver provides support for the bidirectional parallel port 140 found on many Sun machines. Note that many of the newer Ultras 141 actually have pc style hardware instead. 142 143config PARPORT_1284 144 bool "IEEE 1284 transfer modes" 145 help 146 If you have a printer that supports status readback or device ID, or 147 want to use a device that uses enhanced parallel port transfer modes 148 such as EPP and ECP, say Y here to enable advanced IEEE 1284 149 transfer modes. Also say Y if you want device ID information to 150 appear in /proc/sys/dev/parport/*/autoprobe*. It is safe to say N. 151 152config PARPORT_NOT_PC 153 bool 154 155endif # PARPORT 156
