11 Debug Interface

The simualtor supports Linux and Windows® based debugging. It is recommended to use the GDB interface to debug on Linux based hosts. The kernel debugger interface can be used to debug on Windows based hosts.

11.1 Kernel Debugger

This only applies to the Windows® version of the simulator and not to the Linux version.

The simulator can interact with the kernel debugger through:

∙EXDI interface (see Section 7.20, "EXDI Server Device", on page 108).

∙Serial port connection.

The serial ports can be configured so that any data read from or written to the simulated serial ports is made available to the host machine. The serial ports can each be configured to do this using either a named-pipe, or the actual serial port hardware.

The automation commands "GetCommPort" and "SetCommPort" are used for this purpose, see Section A.7.10, “Serial”, on page 235.

Use the serial ports "SetCommPort" command to set the simulated serial port to use a specific COM port. For example, to set the second serial port in the simulation to use COM4 for its communication, you would type

Serial:1.SetCommPort COM4 57600

The simulator will program the appropriate COM port (COM4 in the above example) to 57600 baud, 8 bits, no parity, 1 stop bit, no flow control.

All characters transmitted by the simulation through the serial port (second serial port in the above example) will be sent out to the given COM port (COM4 in the above example). In the same manner, all data received by the simulator through the given COM port (COM4 in the above example) will appear as received data in the simulated COM port.

To set the simulated serial port (COM1) to use a named-pipe you would type

Serial:1.SetCommPort pipe

The simulator will program the appropriate COM port (COM1 in the above example) to use the named-pipe “\\.\pipe\SimNow.Com1” on the host to transfer data between host and the simulated machine.

4.4.5 specifications

AMD 4.4.5 is a robust version of the AMD software ecosystem that focuses on enhanced performance, stability, and efficiency for users relying on AMD processors and graphics cards. This iteration brings various features and technologies designed to optimize gaming, professional applications, and general computing tasks.

One of the standout enhancements in AMD 4.4.5 is the integration of Smart Access Memory technology, which allows the CPU to access the full graphics memory directly. This feature enhances data flow between the CPU and GPU, leading to improved frame rates and overall performance, especially in memory-intensive games. Users can experience a marked increase in gaming performance without the need for additional hardware upgrades.

Another significant feature introduced is the updated Radeon Software Adrenalin Edition. This software update encompasses optimizations for various games, ensuring that gamers can enjoy a seamless experience with the latest titles. The Adrenalin interface also provides features such as Radeon Chill, which helps reduce power consumption during less demanding scenes, and Radeon Anti-Lag, designed to minimize input lag and enhance responsiveness in competitive gaming.

Additionally, AMD 4.4.5 brings the latest drivers that include important performance enhancements and bug fixes that allow for greater system stability. Regular updates ensure that users have the best experience with their AMD hardware, and it significantly bolsters compatibility with the latest gaming titles and software applications.

AMD's Enhanced Sync technology offers users the ability to eliminate screen tearing and stuttering while delivering smooth gameplay. It dynamically synchronizes the refresh rate of the display with the frame rates produced by the GPU, improving the visual experience significantly.

With the introduction of FidelityFX Super Resolution, AMD continues to bolster its suite of technologies that enhance graphics quality and performance. This feature allows lower-resolution images to be upscaled effectively, making it easier for users to enjoy high-end visuals without taxing their hardware excessively.

In summary, AMD 4.4.5 represents a comprehensive update for users by integrating cutting-edge technologies that cater to a wide range of applications from gaming to content creation. With enhancements across the board, AMD reaffirms its commitment to providing high-performance solutions that keep pace with the ever-evolving technology landscape. Whether for gaming aficionados or professional creators, the capabilities offered in this version make it a significant milestone in the AMD software ecosystem.
