Code quality improvement for Intel Windows Graphics Driver

Abstract

There are already many software tools present and many application software's that being developed. These is because the technology needs to be updated according to the requirements. During these busy times, Developing and updating technologies is itself a big challenge. If any bugs occur in future or to keep track of features are added are working properly according to requirements, it needs some tools to keep track of it. For these things to happen, it requires some methodology to improve debug time like ETL (Event Trace Log) for multiple display features. The other things are that, code that is written today has to be written in such a way that it could be used for at least next 10 years. This will reduce the time of adding the same code simultaneously. Collecting the ETL in the encoded form helps in securing the sensitive information present in the trace log. Adding more testing codes in Unit Test Framework (UTF) find more bugs at early stages which will reduce the code cost. Adding MMIO (Memory Mapped I/O) verifier rules as the part of UTF helps in register verification (Simulates real Hardware context). Addition of MMIO rules for existing and new display features in separate xml file for different platforms makes it easy to identify in which platform feature failure in happening. All these methods help in code quality improvements for Intel Windows Graphics Driver.
