Viewing the Target State

This topic introduces the different aspects of the CPU state that can be viewed and sometimes modified using Intel® System Debugger windows and dialog boxes. The target CPU must be in halted state when its state is viewed or modified. Most windows are empty or display old content when the target is running. The available information depends on the target platform.

Viewing Paging Tables and Translate Addresses

The paging window and the address translation dialog let you view and modify the currently active paging tables and to translate symbols and logical addresses to the corresponding linear and physical addresses.

See Paging Window for details on how to view and modify paging tables.

See Address Translation Dialog Box for details on how to translate an address or a symbol to the corresponding linear and physical address.

Viewing the Global and Local Descriptor Tables

GDT and LDT windows let you view and modify the segment descriptor tables on the target.

See GDT Window for details on how to view and modify the Global Descriptor Table

See LDT Window for details on how to view and modify the Local Descriptor Table

Viewing and modifying MSRs, Registers, and System Registers

See Viewing and Modifying Registers

Viewing Vector Registers

Some processors implement a set of vector registers for supporting vector operations.

Vector registers window lets you view and modify the vector registers.

See Vector Registers Window for details.

Viewing Interrupt Descriptor Tables

The processor accesses interrupt and exception handlers through an entry in the interrupt descriptor table. The IDT window lets you view and modify the Interrupt Descriptor Table.

See IDT Windowfor details.

Viewing Hardware Threads

The Hardware Threads window lets you view the information on active cores and threads on the target platform. Selecting the active hardware thread on target updates other windows to show data on the selected hardware thread.

See Hardware Threads Window for details on how to use the hardware threads window.
