SBP-2 [T10/1155D]
There was discussion about how to get the correct group of people to
address isochronous issues. This is the
area of SBP-2 that is weakest.
Action - Pete McLean - to address issue in joint meeting on Wednesday.
Printer people want to add another ORB that will have a bi-directional
pipe. Peter Johansson agreed to
make up a proposal for this and will add an example with the proposal.
Peter will bring the proposed
document to the Oct. 7th meeting.
Power up issues - Jeff Wolford stated that Device Bay has decided to allow
no power state changes by
anyone other than the logged in device with correct password. No
additional power may be used prior to
successful login. After some discussion it was concluded that this need
not be addressed in SBP-2 as it will
be delt with in the Device Bay specification.
Page by page review of the annexes in SBP-2 including the new annexes from
STS and clauses 6 through
10 was held. Numerous editorial changes were agreed to and Peter Johansson
will turn a new revision
reflecting these changes. At this time all of SBP-2 except clauses 11 and
12 have undergone editorial
review.

this and report back at the next
