[U-Boot] Call for participation in the U-Boot Mini Summit 2014

[U-Boot] Call for participation in the U-Boot Mini Summit 2014

[Detlev Zundel]

Hi,

as already indicated, we are looking forward to our next U-Boot Mini
Summit at Embedded Linux Conference Europe 2014 which will take place in
D?sseldorf, Germany from October 13 - 15.

The call for papers of the main conference is now open[1] and if you
want to submit a talk for the main tracks, you should note the deadline
of July 11.

For our U-Boot Mini Summit, I'd like to get the schedule completed
synchronized to the schedule release of the main event, which is August
12.  So please submit talk proposals here with at least me on CC.

To coordinate the event better, I have setup another wiki page[2] that
can and _should_ be edited by the interested parties.  Feel free for
example to add yourself to the "interested participants" so that we get
an idea of how many of the U-Boot developers will be there.

Best wishes
  Detlev

Tomorrow is the last day of submitting the talk proposals for U-Boot 
Mini Summit, but there was no response for your e-mail and also there 
are no topics on the wiki site.

So, will be there only an open discussion?

Some time ago I've send a RFC:
http://lists.denx.de/pipermail/u-boot/2014-May/179241.html

It was about PMIC/POWER framework rework - but I didn't have a time to 
work on it.

Simon Glass has done a lot of work by introducing driver model to serial 
and gpio last time, and I would like to rework PMIC drivers and pmic 
framework using the DM.

So, can I reserve about 30min slot for a discussion?

I think there were a few other requests, off-list.  Also, we might want
to extend the deadline slightly as talks for the main event were just
accepted/rejected so folks are now sorting out if they can go or not.

[U-Boot] Call for participation in the U-Boot Mini Summit 2014

[Masahiro YAMADA]

Hi.


2014-08-12 6:08 GMT+09:00 Tom Rini <trini@ti.com>:

I will be in U-Boot mini summit 2014.
I am thinking about giving a talk on Kbuild and Kconfig.

Kbuild - I think it is already stable enough, but I'd like to
have a quick review of the big change we had in U-Boot
in the past year.

Kconfig - We have just switched to Kconfig.  I will explain
how Kconfig was adjusted for U-Boot and why the current approach
was chosen and then what will happen in the next phase.


BTW, I am not good at talking. Nor am I good at English.
(I hope my presentation won't be a disaster...)
But I'd like to challenge a new thing.
Could you bear with me during a 20min slot?

Marek, thanks for pushing me to do it!

Hi all,

I got my talk, "Secure and flexible boot with U-Boot bootloader", accepted for 
the main track it seems. It's mostly about "use fitImage and use UBI on NAND" 
kind of talk, which covers introduction to fitImage and storing system 
components on UBI/UBIFS to prevent problems like silent data corruption on 
modern systems.

That being said, I believe I won't be able to cover the fitImage verified boot 
part properly, so I might as well cook a talk for the u-boot summit about this 
advanced topic.

What do you think ?

Best regards,
Marek Vasut

I absolutelly agree, this is a big topic and it should be certainly covered. 
Thank you for taking this up !

It's pretty OK, don't worry :)

If this was up to me, I'd be really happy if you got one slot for each of the 
topics ;-)

Indeed some requests have been sent :-).

I'd like to share with the u-boot mailing list the proposal of my talk
for u-boot's Mini summit in the ELCE2014.

__Mainline u-boot for Tizen 3.0 - ?war story?__

Abstract:

Utilization of u-boot bootloader at Samsung's Linux powered platforms
has a long history.  For Tizen 3.0 the reference devices for mobile
profile (RD_PQ and Odroid U3/X2) are due to run with u-boot developed
with open source philosophy applied. It means that the code was
developed, reviewed and tested first in the open source and then
reused in Tizen.

Introduced changes to mainline code were minimal and only necessary for
assuring backward compatibility. In his presentation Lukasz will
briefly cover history and future plans of u-boot development for Tizen
(as e.g. ongoing work on single binary for Odroid U3 and M0), explain
key aspects of persuading community to accept solutions tunned for
mobile devices, present remarkable u-boot's ?war stories? and give a
handful of tips for successful cooperation with community.

I would need around 25 minutes for talk and 5 more for discussion.

Any comments appreciated :-).

[U-Boot] Call for participation in the U-Boot Mini Summit 2014

[Masahiro Yamada]

Hi Detlev,


I'd like to have a presentation at U-Boot mini summit 2014.


------------------------>8---------------------------------------

Kbuild and Kconfig for U-Boot

Abstract:

U-Boot has had big changes on its build system in the past year.

Kbuild and Kconfig provide us a lot of benefites; however there have been
various hurdles to overcome for switching over to the new infrastructure.
Porting had to be done carefully, step by step so as not to break
any exisiting features and boards.

This talk will explain how the migration was done, why the current approach
was chosen and what will happen in the next phase.

------------------------8<-----------------------------------

I will need about 30 minites for this talk including discussion.

Count me in on this talk ;-)

btw. Tom etc., do we have some "list of talks" for the minisummit or some 
program for it available somewhere ? When is the deadline for CFP ?

We had a talk about that exact topic last year on the main track by
Simon and in the mini summit by Jagan Teki[1].  In what respect will
your talk differ from that?

I really appreciate such a "war story" talk.  Actually I tried nudging a
lot of people to do such a thing but until now without any success - so
I'm all the more happy to see it finally appear.  I guess it will be
very instructive to share such inside experience on how to integrate a
decentralized open source component in a professional work flow.  Such
procedures have materialized around the Linux kernel, but the situation
is not so clear in the bootloader area that has traditionally seen a lot
of "fire and forget" strategies.

As I did not see any negative reaction to that talk, I'd say the talk is
accepted.

I am sending my late abstract:

"Power(full) framework based on Driver Model - discussion"

Abstract:

There are lots of various Power Management IC's in the Embedded Systems
nowadays. Each can provide the same functionality, like a voltage 
regulators, chargers, signal switches and some more - which are usually 
driven in a device specific way.

Beside the battery state, the current PMIC framework provides registers 
read/write operations only. So the user is obligated to check the 
documentation and set a specific value of some register to change the 
state of any regulator.

To solve the problem with driving common functionality - the Driver 
Model can be used.

The aim of this discussion is to present author's conception about how 
to use the Driver Model, and get the feedback from the listeners
to introduce a common and functional framework architecture.

I suppose that I will need about 30 minutes for this discussion.

Best Regards.

I believe there is never enough advertising when it comes to fitImage, since
we want to get rid of uImage. On the other hand, I see no point in artificially
filling the talk slots, so consider my offer only as a backup solution.

Why do we want to get rid of uImage?  It's easier to work with than
fitImage.  Or do you just mean get rid of legacy multi-image support?

There is no longer much point in uImage other than the size of it's 
implementation. The code which handles the uImage format is smaller
than the fitImage handler, since it doesn't have to deal with all of
the DT stuff.

On the other hand, the fitImage is more flexible -- you can pack in
multiple images , you can select stronger checksum algo than crc32
(which is important), you can sign it. The downside is that not many
people even know of all these options fitImage gives them.

The uImage has been legacy for years now, it's not going away any soon,
but we need to push for stronger adoption of the fitImage format. This
is especially important if you are concerned about things like silent
data corruption of the kernel image or protection against tampering.

Indeed, 'getting rid of uImage' might have been a bit strong wording,
but eventually, uImage should be deprecated.

In which way?

It worries me we even had something like that.

In most developer work flows at least zImage then uImage then fitImage
are the easiest to work with, in that order, for ARM.  For ARM64 Image
in the next release will probably release uImage as the easiet to work
with.

fitImage seems useful in a lot of deployment scenarios.  Having to craft
up a good skeleton device tree in most cases is an annoying to overcome
barrier for a development workflow.

I wonder if we could easily address that by building in the
functionality to mkimage? For the common case of a kernel, FDT and
ramdisk I don't see why anyone needs to write a .its file. It's just
boilerplate.

Maybe.  Or at least add in an example that doesn't do any reloc to it
AND make it clear that's what it does.  Looking over my normally lost
boilerplate its file, it's kernel_noload that doesn't relocate things
around to the load/entry point so a generic example could be made.

Sorry for my late input on this regard.
But if there's still a possibility to have another talk I'd like to
propose mine "ARC - new first-class citizen in U-Boot" (which was
declined for main ELCE2014 event).

Abstract is in-lined below.

===================
U-Boot is a de-facto standard bootloader for Linux-driven embedded
systems. It provides flexible means for loading kernel and if required
image of filesystem from different media be it embedded non-volatile
memory, attached storage or even network share. Linux kernel was ported
to DesignWare ARC a while ago and starting from version 3.9 the port was
accepted upstream. Now to enable real-life device booting on custom
hardware decision was made to port U-Boot for ARC. This presentation
unveils reasons to start the project, highlights milestones passed
during porting process, touches some pitfalls and encourages more
engineers and companies to use and contribute to U-Boot project.
===================

I'm not sure if this kind of speech is of any interest for existing
U-boot developers, but I may indeed emphasize technical aspects now.

Any feedback is more than welcome.

Regards,
Alexey

If that's an introduction to porting U-Boot, it might bring to light some new 
ideas about the porting process and also point out some obstacles we were not 
aware of. I think it's a good idea to have such a war story ;-)

Agree, so I'll re-focus my speech to more technical questions like
challenges I met, things to improve etc.

Do you guys want to get my presentation beforehand or I may just bring
it with me?

Just an additional info:

In fact I was advertising a lot for this possible boot scenarios [2]
talk in India
last year other than U-Boot Mini 2013 starting from legacy to fit.
What I understand that developers are very interested and they
asked more possible useful scenarios with in the fitimage stuff
like loading different kernels (as part of visualization) etc.

May it would be good if any one is interested to talk on that more.

Hi Alexey,

thanks a lot for your willingness to do the presentation at the mini
summit.  As I personally thik your talk fits our agenda pretty well and
nobody has said anything different, it is therefore accepted.

Currently I plan for 20 minutes / 10 minutes Q&A slots, would this be ok
for your talk also?

> Do you guys want to get my presentation beforehand or I may just bring
> it with me?

It would be good to send a copy of the presentation beforehand just in
case something breaks. Believe me - _something_ will ;)

Cheers
