I managed to track down the problem. cell_start_spus is being called
multiple times. Each time it is called the SPUs expect the buffers to
be stored in a different location. However, when the batch data is
later sent to the SPUs, the addresses for one of the earlier invocations
of cell_start_spus is used. The buffer the SPUs actually look at is
empty, and 'cmd_batch(): assertion 0 failed.' results.
I added a printf to cell_start_spus. I've attached the GDB output with
backtraces at each call to cell_start_spus.
It seems to me that the state tied to the SPUs should be treated as a
singleton. cell_start_spus should only be called once, and later calls
to cell_create_context should use the same singleton data. If this
approach seems correct, I'll start working on it tomorrow.
