      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
