Hello everyone!
Does Vista/Win7 unload *ALL* device drivers when shuttig down?
We want to do some clean up work in the driver unload function, but it seems that the driver unload routine was NEVER called when OS shutting down on Vista/Win7. (It is OK on XP).
Does anyone know how to guareente that the all the drivers will be unloaded on Vista/Win7.
Thanks a lot.

HW

No, OS shutdown differs from driver unload.
As you’ve seen, driver unload function may be not called. Register a
shutdown callback if you need so.

Dear Pavel:
Thanks for your kind reply.
I know how to register shutdown callback in user mode.
But how to do it in kernel mode?
Could you please give me some pointers on this?
Thanks a lot.

Hi, Xing
Why you not do that in the power request such as IRP_MN_SET_POWER, and

a. Because not every driver, even PnP, sees these IRPs.
For example, NDIS miniports don’t see IRPs and use
NdisMRegisterAdapterShutdownHandler
to register for shutdown notifications
b. Sometimes one wants to use IoRegisterLastChanceShutdownNotification

WDM audio miniport drivers.
We implement the IAdapterPowerManagement interface as required.
But seems this interface doesn’t called when shutdown.

What kind of miniport? Typically as a mp you do not get any irps, MJ_SHUTDOWN or MJ_POWER and registering for either is not possible.

Yes. We are miniport driver and don’t handle IRP directly.

a. Because not every driver, even PnP, sees these IRPs.
For example, NDIS miniports don’t see IRPs and use NdisMRegisterAdapterShutdownHandler
to register for shutdown notifications
b. Sometimes one wants to use IoRegisterLastChanceShutdownNotification

Actually, we want to differentiate S3 and S5.
But we can’t because the default SxD mappings set by bus driver are S0->D0, S3->D3,S5->D3.
From the miniport driver’s point of view, we can’t distguish S3/S5.
But we still want to do something we system is tansitioned to S5 state. So…

Actually, we want to differentiate S3 and S5.
But we can’t because the default SxD mappings set by bus driver are
S0->D0,
S3->D3,S5->D3.
From the miniport driver’s point of view, we can’t distguish S3/S5.
But we still want to do something we system is tansitioned to S5
state. So…
You’ve been asked why you want to do this at least once and haven’t
answered. If you offer the reason why detecting the S5 state transition
is so important to you then you will be more likely to get some useful
information.

Dear James,
Thanks.
The reason is we want to set different hardware registers according to system state (S0/S3/S5).
Our driver are miniport drivers and don’t directly handle power IRPs.
When system power state changes, the port driver will notify us and direct our driver to appropiate device state.
However, the default SxD mappings set by bus dirver are as follows:
S0->D0
S3->D3
S5->D3
So when port driver direct us to D0 we know the system power state is S0.
But we can’t distinguish S3/S5.
Since S5 correspond to shutdown, so we want to set S5 state registers in shutdown callback.
Best regards,
HW

I think everyone is looking to find out why your device cares if the system
is going to S3 or S5 since you’re going to D3 in either case. Are you trying
to work around some bug in the chipset?
