Support has been added for SDMA RLC queues which are used for host to device and device to host "memcpy" calls. Previously the SDMA engine was disabled which caused GPU BLIT kernels to be called. This removes the environment variable disabling SDMAs which has two main benefits: - It will be much easier to debug host/device transfer by using SDMA debug flag. - Simulation time is improved since we no longer need detailed GPU simulation to copy data and instead are doing a simple large DMA Change-Id: I7524245731d301b5c26394318f2156ed6b4c983a Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/62717 Reviewed-by: Matt Sinclair <mattdsinclair@gmail.com> Tested-by: kokoro <noreply+kokoro@google.com> Maintainer: Matt Sinclair <mattdsinclair@gmail.com>
