| + | 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. | ||
| You’ll need the “gpgpu-sim-sha” found [[http://goo.gl/S1ts6|here]]. **NOTE:** If you setup GPGPU-Sim from the public git server instead of pulling from our repositories, you may not be able to submit review requests to our GPGPU-Sim patches repository | You’ll need the “gpgpu-sim-sha” found [[http://goo.gl/S1ts6|here]]. **NOTE:** If you setup GPGPU-Sim from the public git server instead of pulling from our repositories, you may not be able to submit review requests to our GPGPU-Sim patches repository | ||
