MiniportSynchronizeInterruptruns at the DIRQL assigned when the driver'sMiniportInitializeExfunction calls theNdisMRegisterInterruptExfunction. Like any driver function that runs at DIRQL,MiniportSynchronizeInterruptshould return control back to the caller as quickly as possible, and it can call only thos...
DXGKDDI_WRITEVIRTUALIZEDINTERRUPT callback function (d3dkmddi.h) Return value DxgkDdiWriteVirtualizedInterruptreturns STATUS_SUCCESS upon successful completion of the write operation; otherwise it returns an appropriate NTSTATUS code. Remarks KMD'sis used in the context of virtualizing GPU devices, speci...
For passive-level interrupt objects, drivers must call WdfInterruptTryToAcquireLock instead of WdfInterruptAcquireLock, when running in an arbitrary thread, such as a queue object callback function. For example, the driver might call WdfInterruptTryToAcquireLock from EvtIoRead....
The MiniportHandleInterrupt function is required if a driver's NIC generates interrupts. MiniportHandleInterrupt does the deferred processing of all outstanding interrupt operations.SyntaxC++ Copy W_HANDLE_INTERRUPT_HANDLER MiniportHandleInterrupt; VOID MiniportHandleInterrupt( _In_ NDIS_HANDLE Miniport...
Your driver cannot callWdfInterruptReleaseLockbefore the framework has called the driver'sEvtInterruptEnablecallback function or after the framework has called the driver'sEvtInterruptDisablecallback function. For more information about theWdfInterruptReleaseLockmethod, seeSynchronizing Interrupt Code. ...
You can either debounce the pin with hardware, or use the debounce in callback function like in this simple example: from machine import Pin import utime intTime = 0 debTime = 100 def cb(p): global intTime if utime.ticks_diff(utime.ticks_ms(), intTime) > debTime: print(p.value...

If the interrupt is not from the hardware that this EvtInterruptIsr callback function services, the driver must return FALSE. If the interrupt vector is being shared, the system calls another interrupt service routine.If the driver has not requested passive-level handling for an interrupt object,...
