question on resume from hibernation - pdo d0entry not called?

James_Harper · March 5, 2009, 5:56am

When resuming from hibernation, I see my wdf bus driver return from the
‘WdfPowerDevicePrepareForHibernation’ state in its D0Entry routine, and
then I see the enumerated scsiport fdo get called in its
HwScsiAdapterControl(ScsiRestartAdapter) routine.

Nowhere do I see the pdo enumerated by my bus get called with its
D0Entry routine.

If you remember a previous thread of mine, I saw my pdo’s d0exit get
called with D3 instead of PrepareForHibernation, so I’m thinking maybe
this could be a side effect of that bug. Or maybe this is expected
behaviour… anyone?

Thanks

James

Put a bp on HwScsiAdapterControl(ScsiRestartAdapter) and run
!wdfkd.wdfdevice (the pdo) fff
!wdfkd.wdflogdump (your driver)

And send the output.

Curiously… the first thing I see on resume is:

Is that a bug in scsiport, wdf, or my drivers?

!wdfkd.wdfdevice (the pdo) fff
!wdfkd.wdflogdump (your driver)

And send the output.

I’m waiting on the second one now… it’s taking a while

How do I get the wdf handle for the pdo?

How do I get the wdf handle for the pdo?

Hold that thought… it appears that maybe wdflogdump might do it…
it’s just slow as I’m debugging over tcpip.

!wdfkd.wdfdevice (the pdo) fff

Based on the output of the log below, I'm guessing that I've got the
right wdfdevice...

I wanted you to specify fff as flags for !wdfkf.wdfdevice. That will give the last 8 states of the pdo

Based on the output of the log below, I’m guessing that I’ve got the
right wdfdevice…

Which is where we call your D0Entry routine. My guess is that it happened before the debugger got its bearings. I suggest you set some global to a known value in D0Entry and clear it on D0Exit and see what its value is when you think D0Entry has not been called

give

Make sure that the PDO doesn’t have DO_POWER_PAGABLE flag (call WdfDeviceInitSetPowerNotPageable).

WdfDeviceInitSetPowerNotPageable).

Thanks. I already went through all of that on a previous thread. Having
set the power pagable flag it hibernates but doesn’t call the pdo D0Exit
correctly. I worked around that, but now D0Entry doesn’t get called at
all on the pdo on resume from hibernation.
