Subject: Minutes from Wednesday's SPIRIT debug working group meeting,
and other related matters.
The
minutes are attached. Please let me know if you have any comments.
I
am aiming to hold our first weekly conference call during the week of
the 9th of October. That meeting will be open to the contributing members of
the group (currently ARM, Freescale, Philips, and ST). In addition other SPIRIT
members, including reviewing members, who are considering becoming contributing
members of the group may participate in up to 2 meetings of the group
before becoming contributing members.
Please
let me know if you wish to participate, and if so when you are available during
the week of the 9th. Please also let me know what time zone you are in.
Note,
however, that I will be on vacation for the next 2 weeks (returning 2nd
October). If there are any urgent matters concerning the group during this
period please contact Chris Lennard (chris.lennard@xxxxxxx),
copying me.

Minutes:
========
- Qn: Concern about proprietary info being disclosed in the IP-XACT data
- Ans: IP-XACT should describe the type of information commonly found
in technical reference manuals (i.e., open info). e.g., ARM does
regards the info needed for debug targetting would be open
- Qn: How do you create IP-XACT descriptions for legacy IP?
- Ans: In the SoC Design flow, IP-XACT descriptions will be a by-product
of the system development process. For boards, etc., there would
need to be IP-XACT editors or similar tools, although in simple cases
a schema aware XML editor works quite well. For some hardware
it is possible to generete a partial IP-XACT file from autodetection
of the the debug hardware.
- Qn: Debuggers need to consider type of target connection. Is SPIRIT
considering this?
- Ans: Worth considering this as future work, but first point of action
is to agree on target description format. Regardless of the
target connection, this format must be agreed
- Qn: Has SPIRIT considered alignment with the Multicore Association?
Key members are: Mentor, Freescale, Windriver
- Ans: Will look into how we keep this organization in the loop. The
strong membership overlap will help
- Qn: Should description of system SW be considered now? Needed for debug
- Ans: SPIRIT would like to do that following the HW description solution.
Reason for this is that the HW description is the smallest step
forward, but also we would need the OS vendors involved for the
SW description stage
- Qn: For register descriptions and debug behavior, consider SystemRDL. What
is the relationship
- Ans: The Data-Model working group will be liasing with SystemRDL. This
language has not been donated to SPIRIT (i.e., SPIRIT is language
neutral), but the meta-data that describes registers should be
aligned between the groups. SystemRDL's focus is register generation,
IP-XACT is design documentation.
- Qn: Does IP-XACT allow for user-specified extensions?
- Ans: There is a vendor-extension mechanism for this supported
- Qn: Should we add identifying information about the object file formats?
- Ans: This is an interesting idea. Should be considered in scope
- Qn: What about the programming scripts to set a target up? Need to
support dynamic as well as static descriptions
- Ans: This could be supported through generators. Process for this
should be considered in scope
- Qn: What about describing trigger conditions, etc.?
- Ans: Could be considered through a Problem Statement / Solution
- Note: There are several other working groups working in the
debug area. For example: Nexus, Multicore Association, OCP-IP Debug
Working Group, JTAG Working Group, ...
- Comments: ARM on behalf of SPIRIT has done a lot of due diligence to
see if any other organization covers the area of this
specification. There are no exact coverage points, but
several elements of overlap (particularly legacy formats).
The Debug Working Group will need to continually assess this
situation as progress is made
- Comments: Neil Stollon is chair of the Nexus working group, and also
member of the OCP-IP Debug WG. He will help with the
group co-ordination
- Note: Eclipse DSDP release for 2007 is releasing June. Need to consider
whether there should be an incremental release that would suit this.
- Note: Eclipse DSDP is wondering what is the work involved in creating
an IP-XACT parser. Should this be a shared development? Should be
considered as part of the requirements development
ACTION:
=======
Chris - Need to get operational mechanism and legal working relationship
with DSDP in place. Co-ordinate with Doug and Anthony.
