Abstract

Disclosed is a device that will read a Device Dependent X (DDX) trace file. The device will send the commands and data that were written in the trace file to the graphics adapter. With this invention, the trace file could be modified in order to step through the commands and data being sent to the graphics adapter. Also, the trace file could be modified so the device could read registers from any point in the trace file. The data and commands in the trace file can be changed and resent to the graphics adapter without having to recompile the DDX code. The invention's main purpose is to identify and reproduce hardware or software problems like diagnostic, stress and hardware validation.

Disclosed is a device that will read a Device Dependent X (DDX) trace file. The device will send the commands and data that were written in the trace file to the graphics adapter. With this invention, the trace file could be modified in order to step through the commands and data being sent to the graphics adapter. Also, the trace file could be modified so the device could read registers from any point in the trace file. The data and commands in the trace file can be changed and resent to the graphics adapter without having to recompile the DDX code. The invention's main purpose is to identify and reproduce hardware or software problems like diagnostic, stress and hardware validation.

FIGURE 00 is a high level flow chart that depicts the overall workings of the invention. 0001 - If the command line options were incorrect print the usage information, 0002, so the user will know how to run the invention. 0003 - Open the trace file so the data in the file can be read. 0004 - Call the device driver to obtain adapter access. 0005 - If access to the graphics adapter was granted, print the adapter information, 0006, else exit the invention, 0009. 0007 - Read the trace file and parse the strings looking for commands and data to be sent to the graphics adapter. See Figure 01 0008 - After writing all the commands and data from the tr...
