1Module options
2--------------
3
4The mwave module takes the following options. Note that these options
5are not saved by the BIOS and so do not persist after unload and reload.
6
7  mwave_debug=value, where value is bitwise OR of trace flags:
8    0x0001 mwavedd api tracing
9    0x0002 smapi api tracing
10    0x0004 3780i tracing
11    0x0008 tp3780i tracing
12
13        Tracing only occurs if the driver has been compiled with the
14        MW_TRACE macro #defined (i.e. let ccflags-y := -DMW_TRACE
15        in the Makefile).
16
17  mwave_3780i_irq=5/7/10/11/15
18    If the dsp irq has not been setup and stored in bios by the
19    thinkpad configuration utility then this parameter allows the
20    irq used by the dsp to be configured.
21
22  mwave_3780i_io=0x130/0x350/0x0070/0xDB0
23    If the dsp io range has not been setup and stored in bios by the
24    thinkpad configuration utility then this parameter allows the
25    io range used by the dsp to be configured.
26
27  mwave_uart_irq=3/4
28    If the mwave's uart irq has not been setup and stored in bios by the
29    thinkpad configuration utility then this parameter allows the
30    irq used by the mwave uart to be configured.
31
32  mwave_uart_io=0x3f8/0x2f8/0x3E8/0x2E8
33    If the uart io range has not been setup and stored in bios by the
34    thinkpad configuration utility then this parameter allows the
35    io range used by the mwave uart to be configured.
36
37Example to enable the 3780i DSP using ttyS1 resources:
38    
39  insmod mwave mwave_3780i_irq=10 mwave_3780i_io=0x0130 mwave_uart_irq=3 mwave_uart_io=0x2f8

41Accessing the driver
42--------------------
43
44You must also create a node for the driver:
45  mkdir -p /dev/modems
46  mknod --mode=660 /dev/modems/mwave c 10 219
