how to create kaffinity mask

I found tool, which allow me to change it.
Interrupt Affinity Policy Tool and unexpected affinity mask type

But i have problem, i set affinity for usb devices, which are using driver usbport.sys and system assigned other drivers to cores i want to make dpc free.
I just need to set affinity for devices in registry which using drivers, that are displaying in latencymon.
I am currently looking for devices which uses tcpip.sys i looked to device manager and checked show hidden devices and open every network adapter -> drivers tab and there was nowhere tcpip.sys driver under these adapters which confuses me, because i woudl expect tcpip.sys would have to do something with network adapters. And yet looking for ntoskrnl.exe and ndis.sys, dxgkrnl.sys.
If know which devices correspond to this.

 

how to create kaffinity mask

Hello,
i need select cpu cores on which will be processed dpc and isr.
And i have no idea how to create kaffinity mask, it is 64bit value, which is in registry as binary value.
I have 8 cores, 4 physical and 4 threads.
I don't even know which are physical and which threads and how to obtain such information.
I want to exclude 2 physical cores from processing dpc and isr.

IoConnectInterrupt routine (Windows Drivers)
There is calculator, but i don't know if affinity mask is same as kaffinity mask and i didn't find anything usefull searching for kaffinity mask.

Thank you very much.

 

network connections

Not really, no. The system will just choose a network it has the most affinity for (whichever one performs better to route to a given resource). I can't imagine any scenario where the system would ignore the great wired connection to use wifi instead.
