can windbg k command show call stack of user mode when debugging kernel mode

tony_zhutony_zhu Member Posts: 23

each time i am debugging kernel mode, and i have chance to use k command to check call stack as well as !process to check current process.

suppose i am debugging WDDM, and i place a breakpoint on this function, DxgkddiBuildpagingbuffer, when the breakpoint is hit, then i use !process to check current process is LogonUI.exe, but windbg k command shows

dxgmms2!VidMmWorkerThreadProc+0x9
nt!PspSystemThreadStartup+0x55
nt!KiStartSystemThread+0x2a

the call stack is from nt!KiStartSystemThread

Is LogonUI.exe part of system process?
