Some degree of SMP modelling is straightforward: just instantiate N
CPU components, and wire them up in a sid configuration file in
whatever way is appropriate. Some of the flexibility can be expressed
using the C++ configuration frontend's command line options.

A complex TLB may be pretty hard to model as an isolated sid
component, because of the interconnection with a typical MMU's
page-table-fetching logic.

If you're not sure what flavour controller you'd like, then invent a
very simple one, and perhaps script it in tcl. Or use a secondary
general purpose processor with DMA-only "firmware".

Can you suggest an example to help me see what you mean? In some
cases, supporting a "board" just means assembling a configuration from
existing components, which is relatively simple. In others, it
requires writing new components, which can span the whole spectrum of
complexity.

Red Hat is contracted to continue development of SID-based simulator
ports, some of which are made public on an ongoing basis. These are
generally focused efforts toward particular customers' requirements,
though occasionally create nice general-purpose components. There are
no plans at present to dedicate manpower to improving SID for its own
sake. We would of course be happy to help users help themselves.
