hello. iam cant english very wall. sorry.
Irq number I had obtained through the inf file.
I obtained the Interrupt vector by using the createinterrupt () to interrupt the connection.
I have one I want to assign an interrupt to the CPU.
To assign an affinity in the inf file [ddinstall.HW] was used.
However, check with winDBG 0x3 This value was the result of affinity.
Also in the device driver source by using the WdfInterruptSetExtendedPolicy () tries to get affinity.
But I did not come get the desired affinity.
Please help to assign affinity.
This is my inf file and source code is written.
My development environment is a dual-core of win7, kmdf.
