| + | If you would like to test extensions to the PTX ISA, you may need to modify the Lex+Yacc ISA parser in GPGPU-Sim to enable these extensions. In order to do this, you will need to generate your own ISA parser source code within the GPGPU-Sim code base. Below are instructions for setting up gem5-gpu using the full GPGPU-Sim source to allow for these ISA modifications. | ||
