Miniport that should not be unloaded at stand by and hibernation

I have a virtual miniport adapter (NDIS 6.0) that I need to remain loaded
during stand by and hibernation (I am communicating with a service which I
don't control that demands this). I have set
NDIS_MINIPORT_ATTRIBUTES_NO_HALT_ON_SUSPEND in the registration attributes
in MiniportInitializeEx.

Still when the PC is going into stand by MiniportHalt is called with
haltAction = NdisHaltDevicePoweredDown.

Anyone who has an idea of preventing this?

Best regards,
Fredrik Jansson

Carefully read the docs on NDIS_ATTRIBUTE_NO_HALT_ON_SUSPEND. Your
miniport needs to properly reply to PNP requests in order for NDIS to
not halt the miniport during standby/hibernate.

I will try this... I had totaly missed the OID_PNP_CAPABILITIES requirement.

Many thanks, really helpful!

Best regards
Fredrik

Halting your miniport during power down is not going to cause your driver to
get unloaded because from PnP's point of view, your device is still up and
running.

I don't remember my ndis6x MiniportHalt being called upon suspend. We stall
the hw and turn on WOL in a "set D3" context. I guess op's problem is he
didn't handle PM/PNP related OID correctly so ndis sends "MiniportHalt on
suspend" instead of a D3 request.
