Hello David,

I will try to be specific.

I am writing a custom driver for our card. This is signal processing 
controller.

This is an information after lspci.

03:01.0 Signal processing controller: Unknown device 1819:0504 (rev 01)
    Subsystem: PLX Technology, Inc.: Unknown device 9054
    Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- 
Stepping- SERR- FastB2B-
    Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- 
<TAbort- <MAbort- >SERR- <PERR-
    Latency: 32, cache line size 08
    Interrupt: pin A routed to IRQ 5
    Region 0: Memory at de600000 (32-bit, non-prefetchable) [size=256]
    Region 2: Memory at de500000 (32-bit, non-prefetchable) [size=1M]
    Region 3: Memory at de000000 (32-bit, non-prefetchable) [size=2M]
    Expansion ROM at dd000000 [disabled] [size=64K]
    Capabilities: <available only to root>

In principle i have windows driver, but i can not understand how it works.

Thanks
Kirill
