MPPWG was the Mobile Phone Profile Working Group, which I led in an ill-fated effort to define an open API for phones built on Linux,
back before Android swept the field. We did have talks at a couple ELCs.

Hey Scott! It's good to hear from you.

I hope you are doing well!

It's been a few years since we used the MPPWG acronym, but I should have
remembered it.

Overall - Is each item below intended to be a standalone page, or

is the intent that sub-topics will be sections within a top-level page?


Some of the sub-topics (e.g. RealTime) really are big enough to have

their own top-level page (or even several pages).


Maybe this will depend on the number of talks that end up on a page?

I'm not sure what "Status Check" is - can you give an example talk in this category,

or describe it more?

Maybe add "Legal" here?

LTSI might go better under "distributions"?, but I'm not sure.

There are lots more: OpenWRT, Embedded Debian, Debos, etc.

How would you categorize ELBE, which builds binary distributions from Debian?

Would it go on this page?


> * Scheduler

I'm not sure I see scheduler as a top-level page. I'm not sure how many

scheduler talks we've had. Power-management scheduling was a big

topic for a while (e.g. big.LITTLE), but maybe going back farther there

were lots of talks when the O(1) scheduler was introduced.


> ** Real Time

RealTime is big enough to deserve it's own top-level page.

Likely, Scheduler is not big enough to deserve it's own top-level page.

In fact, RealTime might deserve two pages: one for PREEMPT_RT

and the other for dual-kernel approaches (e.g. Xenomai)

I'm not sure what the "Source code" category is here.

Does "IO scheduling" go here?

Security divides into multiple categories. There are mandatory access control

systems, like SELinux, AppArmor, Smack, Tomoyo. And then there are different

aspects of security like:

** Secure Boot

** Cryptography

** Trusted stores (TPM)

** Hardening

OK - maybe this should be a standalone page, but it's kind of in the

non-technical category of pages.

We need Intel or x86 as well (and maybe mips)

Don't we already have Scheduling above?

I would put Fuego underneath a sub-category of

** Test Frameworks

*** Fuego, KernelCI, Kselftest,


I would add:

** Board farms and infrastructure

Not sure what "MPPWG" is.

Add ftrace here.

I thought Tomoyo was a security system, not a distro, but I could be wrong.

Legal could also go here?

This category seems to be "Development Tools", not applications.

I think I'd stick these under "networking", but some are higher-level protocols.

I don't think that "Open Source Projects" is a good category for these sub-topics:


> ** Zephyr

We should probably have a "non-Linux RTOS" page. I think there have been several

different talks over the years for non-Linux OSes (NuttX, Zephyr, Free RTOS, etc.)

> ** Nine-Dollar Computer CHIP,

We should have a "Hardware" category for these board-specific talks.

These should be under networking

I think I'd put "Home Automation" as it's own topic (not under IoT)


maybe also add "Embedded Industrial Systems" as a topic?

I'd put Robotics and Drones under verticals.
