!va2pa [VirtualAddress (hex)] [pid ProcessId (hex)]
Converts the VIRTUAL address to the PHYSICAL address.
[VirtualAddress (hex)]
The target virtual address.
[pid ProcessId (hex)] (optional)
The Process Id of where you want to convert the address based on it.
In the , the pid (parameter) is ignored. If you want to view another process memory, use the '' command to switch to another process memory layout.
The following command shows the physical address of nt!ExAllocatePoolWithTag.
The following command shows the physical address of nt!ExAllocatePoolWithTag+5.
The following command shows the physical address of fffff800`4ebc9370.
The following command shows the physical address of fffff800`4ebc9370in the process layout of process id (0x4).
This function works by calling DeviceIoControl with IOCTL = IOCTL_DEBUGGER_VA2PA_AND_PA2VA_COMMANDS, you have to send it in the following structure.
You should only fill the VirtualAddress of the above structure when you want a physical address and fill the above PhysicalAddress when you want a virtual address. Also, set IsVirtual2Physical to true in the case of virtual-to-physical and set it to false in the case of physical-to-virtual.
If you want to convert based on another process memory layout, then put its process ID. Otherwise, put the current process id on it. ProcessId is ignored in debugger mode.
If the virtual address or process id does not exist, then it shows 0.
This command is guaranteed to keep debuggee in a halt state (in Debugger Mode); thus, nothing will change during its execution.
