Hi All,

Mike L put together the attached list of work items based on the design document we shared with you last time.

If we aim for a 1st slice that gives us the following use-case, "Basic instruction trace of a snapshot of a V8 system with ETMv4” then we identify that the following work packages are needed.

TFDFMT  - Trace frame deformatter
TPKTPROC03 - ETMv4 Instruction packet processor
TPKTPROC03a - ETMv4 configuration input
TPKTPROC03b - ETMv4 Instruction output pack structure
TPKPTDEC03 - ETMv4 Instruction decode
MEMACC01 - Memory access interface
MEMACC02 - Memory access - binary file reader
INSTRDCD01 - Instruction decode interface and structure
TESTPRG01 - Basic test program.  Single ID pkt/trc decode from files

Plus 1 of the following implementations of the instruction decode interface
INSTRDCD02 - Decode implementation created for library
INSTRDCD03 - Adaptor implementation for ARM icodec library
INSTRDCD04 - Adaptor implementation for GNU binutils library

NOTE: we are undecided on the best choice for the initial decode implementation at this point.

I hope this helps and forms a basis for discussion.  

Regards,
Mike.

Subject: Re: CS/TSDL Project Scope Brainstorming

Hi CS/TSDL-ers,

Brainstorming the work items in order to populate Serge's project structure can also be the main topic for tomorrow's Trace Decoders call @1600 UK time(*). We're particularly interested to get inputs on work items from TI and ARM for the call.

Regards

Bill

Good localtime,

I am the project manager assigned to CS/TSDL Project by Linaro. I hope
this journey will be something pleasant and fruitful for all the
participants of this project as well as for the community around ARM
technologies and Linux.

So, let's start with an answer to "what?" question.

In order to be able to properly plan the scope of the project we need to
define the first approximation of the project work item structure. Quite
many of the people subscribed to this mailing list have practical
experience implementing trace stream decoders for CoreSight. That
increases our chances of defining a decent approximation of the project
scope, which then will be refined gradually as project continues.

I need your help brainstorming this topic. So, please, throw your ideas
about the potential work items into this thread and I'll be summarizing
your ideas and putting them into a single "backlog", which will get
prioritized according to needs and dependencies afterwards.

Usage of a hierarchical representation of the work items might be a good
idea as it allows seeing the dependencies from the very beginning. So,
something along the lines of the example below is proposed to be used
(the structure below is just an example - I don't have enough technical
knowledge for the area to propose a good initial structure):

    1. Frontend
        1.1. ...
    2. Core
        2.1. ...
    2. Backends
        2.1. ETMv3
            2.1.1. ...
        2.2. ETMv4
            2.2.1. ...
        2.3. STM
            2.3.1. ...
    3. ...

Also, please share your relevant DOs and DONTs from your past
experience. This undertaking needs all your skills and knowledge to
create a fast, reliable and easy to use decoding library.

PS. "CS/TSDL" in the subject stands for "CoreSight/Trace Stream Decoding
Library". Proposals for a better name are welcome. :)
