Since we build off of gem5, all of the dependencies of gem5 are also dependencies of gem5-gpu. It is suggested that before you try to compile gem5-gpu you compile a copy of gem5 to ensure these baseline dependencies are met. gem5 dependencies can be found [[http://gem5.org/Dependencies|here]], and more gem5 information can be found [[http://gem5.org/|here]]. | Since we build off of gem5, all of the dependencies of gem5 are also dependencies of gem5-gpu.

+ | 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 | ||

<code> | <code> | ||
- | cd gem5 | + | cd gem5 |
