This wording is incorrect. PIPE_CAP_STREAM_OUTPUT_INTERLEAVE_BUFFERS
only determines if ARB_tf3 is supported. As per the overflow so query
spec, if this isn't supported, then we should only ever see the ANY
query (but yes, mesa core doesn't check for this), and the per-stream
query does not need really need to be supported.
Multiple streams has its own cap bit, PIPE_CAP_MAX_VERTEX_STREAMS,
therefore if this is one the queries are the same (and both query types
must be supported if PIPE_CAP_STREAM_OUTPUT_INTERLEAVE_BUFFERS is
supported).
With this wording fixed somehow (well I suppose only really the right
cap bit needs to be mentioned, we can easily require all drivers to
support both queries)
Reviewed-by: Roland Scheidegger <sroland at vmware.com>
(And yes, drivers only supporting the existing indexed query but
thinking it's really non-indexed, while also supporting just one stream
like llvmpipe should be fixed to just say this feature is supported and
both queries treated the same.)
