Bus Interface Standard...

NTDEV
1

Hi All,
I am new to the list. I have a WDM driver which uses certain obsolete Halxxx
calls like HalTranslateBusAddress(), HalGet/SetBusData()…I want to replace
that into direct call interface method, using BUS_INTERFACE_STANDARD
obtained thro IRP_MN_QUERY_INTERFACE.

Actually I tried two approaches–

  1. Build a IRP for IRP_MN_QUERY_INTERFACE and fill in the required
    information(GUID,Version,Allocated Interface buffer), send it to the lower
    stack device object but it returned STATUS_NOT_SUPPORTED(0xC00000BB) for
    BUS_INTERFACE_STANDARD.

  2. Use IoQueryDeviceInterface, with GUID_BUS_INTERFACE_STANDARD, obtain a
    list of symbolic links of all device objects in the system that exports this
    interface, again the call succeded with STATUS_SUCCESS but the symbolicLink
    List was NULL.

I thought BUS_INTERFACE_STANDARD was a system-defined interface and should
be available for all WDM drivers trying to use TranslateBusAddress,
GetBusData and SetBusData kind-of calls.

Any help on this problem is greatly appreciated.

Thanks
Ajith

To read or write bus configuration data I send an IRP
IRP_MJ_PNP and IRP_MN_READ_CONFIG/IRP_MN_WRITE_CONFIG
down to the bus driver as described under
http://www.numega.com/drivercentral/tech_tips/cfgwdm.shtml

The DDK notes that one can retrieve the # of actual read or written bytes
trough
the Irp->IoStatus.Information field.
(http://www.microsoft.com/DDK/ddkdocs/win2k/pnp-irps_9ipe.htm)
(http://www.microsoft.com/DDK/DDKdocs/win98ddk/pnp-irps_9ipe.htm)

On Win2k this mechanism works correctly. But on Win98 Gold it always return
zero. What went wrong? Is this a known bug in Win98? Any workarounds?

Thank you very much in advance.

Carsten
