Hi All,
I am running gem5 v21.0.0.0, rocm v1.6.x (built from source). The
simulations run one host CPU (its pair runs a tiny binary and ends exec
quickly) to launch GPU benchmark (hipified Polybench GPU) and one CPU of a
separate core-pair(its 2nd core runs a lightweight binary and ends exec
quickly) to launch a SPEC-17 CPU benchmark on a 3x3 Mesh network. And I am
facing 4 different kinds of errors and am requesting some help regarding
them. The GPU benchmarks do "malloc"s of size ranging from 2GB - 10GB. The
errors appear on various combination of CPU and GPU benchmarks.
(1) The below error appears and disappears on different simulation runs
"""""

void amd::GpuAgent::InitDma(): Assertion `queues_[QueueBlitOnly] != __null

(2) Similar errors with varying values
"""""
