42 * Options :
43 * AUTOSENSE - if defined, REQUEST SENSE will be performed automatically
44 * for commands that return with a CHECK CONDITION status.
45 *
46 * LIMIT_TRANSFERSIZE - if defined, limit the pseudo-dma transfers to 512
47 * bytes at a time. Since interrupts are disabled by default during
48 * these transfers, we might need this to give reasonable interrupt
49 * service time if the transfer size gets too large.
50 *
51 * PSEUDO_DMA - enables PSEUDO-DMA hardware, should give a 3-4X performance
52 * increase compared to polled I/O.
53 *
54 * PARITY - enable parity checking. Not supported.
55 *
56 * SCSI2 - enable support for SCSI-II tagged queueing. Untested.
57 *
58 * UNSAFE - leave interrupts enabled during pseudo-DMA transfers. This
59 * parameter comes from the NCR5380 code. It is NOT unsafe with
60 * the PAS16 and you should use it. If you don't you will have
61 * a problem with dropped characters during high speed
62 * communications during SCSI transfers. If you really don't
63 * want to use UNSAFE you can try defining LIMIT_TRANSFERSIZE or
64 * twiddle with the transfer size in the high level code.
65 *
66 * USLEEP - enable support for devices that don't disconnect. Untested.
67 *
68 * The card is detected and initialized in one of several ways :
69 * 1. Autoprobe (default) - There are many different models of
70 * the Pro Audio Spectrum/Studio 16, and I only have one of
71 * them, so this may require a little tweaking. An interrupt
72 * is triggered to autoprobe for the interrupt line. Note:
73 * with the newer model boards, the interrupt is set via
74 * software after reset using the default_irq for the
75 * current board number.
76 *
77 * 2. With command line overrides - pas16=port,irq may be
78 * used on the LILO command line to override the defaults.
79 *
80 * 3. With the PAS16_OVERRIDE compile time define. This is
81 * specified as an array of address, irq tuples. Ie, for
82 * one board at the default 0x388 address, IRQ10, I could say
83 * -DPAS16_OVERRIDE={{0x388, 10}}
84 * NOTE: Untested.
85 *
86 * 4. When included as a module, with arguments passed on the command line:
87 * pas16_irq=xx the interrupt
88 * pas16_addr=xx the port
89 * e.g. "modprobe pas16 pas16_addr=0x388 pas16_irq=5"
90 *
91 * Note that if the override methods are used, place holders must
92 * be specified for other boards in the system.
93 *
94 *
95 * Configuration notes :
96 * The current driver does not support interrupt sharing with the
97 * sound portion of the card. If you use the same irq for the
98 * scsi port and sound you will have problems. Either use
99 * a different irq for the scsi port or don't use interrupts
100 * for the scsi port.
101 *
102 * If you have problems with your card not being recognized, use
103 * the LILO command line override. Try to get it recognized without
104 * interrupts. Ie, for a board at the default 0x388 base port,
105 * boot: linux pas16=0x388,255
106 *
107 * SCSI_IRQ_NONE (255) should be specified for no interrupt,
108 * IRQ_AUTO (254) to autoprobe for an IRQ line if overridden
109 * on the command line.
110 *
111 * (IRQ_AUTO == 254, SCSI_IRQ_NONE == 255 in NCR5380.h)
