[Ksummit-discuss] Addressing Complex Dependencies - Tuesday 9:30am - Coronado/Devargas

[Luis R. Rodriguez]

[ Note: Plumbers attendees are welcomed to participate in KS tech topics ]

The tech topic thread of addressing complex dependencies was pretty
broad, I've gone over most of the thread and have tried to condense
most ideas discussed into categories. There were four related work
items I had originally noted but Andrzej Hajda also had mentioned his
own work, below they are all together:

  * Functional dependencies (now merged on Greg's tree)
  * Resource tracking / allocation framework
  * Media controller feature graph
  * Linker tables
  * Async probe

Other topics brought up:

  * Probe ordering
  * Generic drivers

And lastly these related subjects were also mentioned which have a
direct impact to dependency relationships:

  * Device hierarchy (just not a tree but a graph)
  * Handling cycles on the graph
  * Graph Cycle solution proposals

There was some overlap in interest between a bit of Audio workshop
folks and this session so we've made arrangements to address only the
shared topics of interest together with the Audio folks at the Audio
workshop first at Sweeney Ballroom CDE, and then move on to address
the rest of the topics in the room assigned for addressing complex
dependencies, Coronado/Devargas.

The shared topics then we will address first at 9:30am are:

  * Generic drivers
  * Device hierarchy (just not a tree but a graph)
  * Handling cycles on the graph
  * Graph Cycle solution proposals

After this is covered we can move on to Coronado/Devargas to adress
the rest of the remaining topics:

  * Functional dependencies (now merged on Greg's tree)
  * Resource tracking / allocation framework
  * Media controller feature graph
  * Linker tables
  * Async probe

I added you to the schedule for Plumbers/KS here:

https://linuxplumbersconf.org/2016/ocw/proposals/4551

You've got about three plumbers users, so I'm not sure I picked the
correct one.

Update:

We've reduced the topics that will be covered and time that will be
required as follows:

The shared topics with the Audio workshop will take place first at
9:30am-10:30am at Sweeney CDE:

  * Device hierarchy (just not a tree but a graph)
  * Handling cycles on the graph proposals

Then we move to Coronado room 10:30am-12:30pm for:

  * Functional dependencies (now merged on Greg's tree)
  * Resource tracking / allocation framework
  * Media controller feature graph
  * Linker tables
  * Async probe

For those who want to brainstorm how to teach driver core about probe order
dependencies, we'll be meeting at 2:00 in "Milagro"

This will be a working session to try and come up with a design. If we make
any progress, we can do a readout later in the week for a larger audience
here at Plumbers.

Cheers,
g.

For everyone interested, the series of "device dependencies tracking" patches
mentioned during the discussion today is available from a git branch at

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git device-links-test

Thanks,
Rafael
