This change sets the properties in hsaTopology to the proper values specified by the user through command-line arguments. This ensures that if the properties file is read by a program, it will return the correct values for the simulated hardware. This change also adds in a command-line argument for the lds size, as it was the only other property used in hsaTopology that didn't have a command-line argument. The default value (65536) is taken from src/gpu-compute/LdsState.py Change-Id: I17bb812491708f4221c39b738c906f1ad944614d Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/31995 Reviewed-by: Matt Sinclair <mattdsinclair@gmail.com> Reviewed-by: Alexandru Duțu <alexandru.dutu@amd.com> Reviewed-by: Anthony Gutierrez <anthony.gutierrez@amd.com> Maintainer: Matt Sinclair <mattdsinclair@gmail.com> Maintainer: Anthony Gutierrez <anthony.gutierrez@amd.com> Tested-by: kokoro <noreply+kokoro@google.com>
