41 | /* |
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) |
