[PATCH v3 0/3] MR5923: winegstreamer: Use affinity to determine 'max-threads' value.

[Brendan McGrath (＠redmcg)]

GStreamer uses _SC_NPROCESSORS_CONF to determine 'max-threads'. On the
Steam Deck, this is configured to be 16 (which is double its number
of logical cores).

_SC_NPROCESSORS_CONF also disregards a process's CPU affinity, thus it
can create more threads than is useful, which ultimately wastes memory
resources.

Using affinity to set 'max-threads' addresses both these problems.
