PHYS command

OSR_Community_UserOSR_Community_User Member Posts: 110,217
1. I want to display virtual addresses that corespond to a physical address.
Something like Softice "phys" command.
How can i do it in windbg ?

2. How make bp in some service thread, which is page out? (this thread is
waiting on port)
Symbols are properly, i change process context and make bp in code, but it
dont work.
(Of course without changing context bp dont work too)

Usually i solve this problem like this:
-seek for some library call
-make bp in library with "j (poi(esp)= ......) ''; 'g' "
When bp occur and i am in properly thread context i can make breakpoints.

Maybe anybody knows simpler method ?
