[DEVEL] Enable support for Renesas platform

From =?UTF-8?B?SHXhu7NuaCBUaMOgbmggSMawb@21:1/5 to All on Fri Nov 18 09:40:01 2022

Dear Debian-developer,

I’m from Renesas Electronics Corporation,

My group is developing to support running Debian OS on our devices, also
for getting ARM System Ready IR certificate.

I recognize that the latest Debian 11 (Bullseye) has the kernel which do
not enable support for Renesas platform.

- *linux-image-5.10.0-18-arm64_5.10.140-1_arm64.deb*

Can you help me to enable those configs, also support the official release version of Debian Live Installer ISO which support Renesas platform?

I classify the defconfig, also classify the new kernel module to support
our devices.

- For new kernel defconfig:

From Josua Mayer@21:1/5 to Fabio Fantoni on Sat Nov 19 08:10:02 2022

Hi everybody!

Firstly seeing an SoC vendor reach out directly about enabling their HW in Debian seems great to me!

I have been doing a little bit of this work in the past, asking the Debian developers to add support for certain devices I had been working with. It
was a very slow process, often years between me establishing contact and an actual release supporting a device.
It turned out that I didn't always have the time to follow through, and
also sometimes encountered bugs specific to the more obscure components
like debian-installer.

I'd like to make progress with this approach again, eventually. Especially
with SoC vendors supporting upstream Linux well, such as NXP (which I work
with a lot) - but also Renesas (my colleague tells me), support is quite possible.
So @Huynh, I'd be happy to assist / answer some questions.

However note I am not part of the Debian project.
I don't know if joining makes sense, I don't know if the Debian project
would like to incorporate some developers who specifically would
collaborate to support certain vendors in Debian.....
Just - there are things outsiders cannot do - like maintaining a "Blend"
e.g.

Sincerely
Josua Mayer

Dear Debian-developer,

I’m from Renesas Electronics Corporation,

My group is developing to support running Debian OS on our devices,
also for getting ARM System Ready IR certificate.

I recognize that the latest Debian 11 (Bullseye) has the kernel which
do not enable support for Renesas platform.

* *linux-image-5.10.0-18-arm64_5.10.140-1_arm64.deb*

Can you help me to enable those configs, also support the official
release version of Debian Live Installer ISO which support Renesas platform?

Hi, thanks for your work, having "out of the box" support on other ARM devices I think would be a great thing.
I unfortunately saw years ago when I tried several ARM devices for work, before choosing what to use for thin clients that the support was
lacking and it took me a long time to prepare a system to use
In recent years I've seen more interest in integrating upstream (mainly
the kernel) and having more support in distributions to make it easier
and faster for users to use them

A first step is enable it in the kernel as you saw, add in stable
version is not possible FWIK but should be added in unstable before
(later, once added and migrated to testing, it will instead be possible
to have it in the backports), if it will be added before the approaching freeze there is a chance it will be added in debian 12

looking at latest version of kernel packaging for experimental in arm64 config about renesas boards seems not present and I don't see an MR for
add it: https://salsa.debian.org/kernel-team/linux

probably can be useful see other contacts related to ARM port (mailing
list, irc, debian developers working on arm on debian) here: https://www.debian.org/ports/arm/

I'm not a maintainer of the ARM part, kernel, bootloader and installer
but I hope you will be able to find someone who can help you and that we
can have a further improvement in the ARM devices support

I classify the defconfig, also classify the new kernel module to
support our devices.

Hi Fabio Fantoni,

Thank for your reply.

Seen like I need to wait for a long time to get the official support from Debian for Renesas platform.

While waiting it, I'll connect with ARM port to get more support.

First times connect with Debian, this is useful for my experience.

Dear Debian-developer,

I’m from Renesas Electronics Corporation,

My group is developing to support running Debian OS on our devices,
also for getting ARM System Ready IR certificate.

I recognize that the latest Debian 11 (Bullseye) has the kernel which
do not enable support for Renesas platform.

* *linux-image-5.10.0-18-arm64_5.10.140-1_arm64.deb*

Can you help me to enable those configs, also support the official
release version of Debian Live Installer ISO which support Renesas platform?

Hi, thanks for your work, having "out of the box" support on other ARM devices I think would be a great thing.
I unfortunately saw years ago when I tried several ARM devices for work, before choosing what to use for thin clients that the support was
lacking and it took me a long time to prepare a system to use
In recent years I've seen more interest in integrating upstream (mainly
the kernel) and having more support in distributions to make it easier
and faster for users to use them

A first step is enable it in the kernel as you saw, add in stable
version is not possible FWIK but should be added in unstable before
(later, once added and migrated to testing, it will instead be possible
to have it in the backports), if it will be added before the approaching freeze there is a chance it will be added in debian 12

looking at latest version of kernel packaging for experimental in arm64 config about renesas boards seems not present and I don't see an MR for
add it: https://salsa.debian.org/kernel-team/linux

probably can be useful see other contacts related to ARM port (mailing
list, irc, debian developers working on arm on debian) here: https://www.debian.org/ports/arm/

I'm not a maintainer of the ARM part, kernel, bootloader and installer

can have a further improvement in the ARM devices support

From Josua Mayer@21:1/5 to All on Sat Nov 19 08:40:01 2022

Some pointers to the actual process I use:
1. boot debian stable with kernel deb from sid
2. install reportbug utility
3. analyse the kernel .config (/boot/config-*), figure out what's missing
4. use reportbug utility to file a bug for "linux" package, asking to
enable kernel configs

5. review flash-kernel package database (this one is responsible for
copying dtb to /boot, and generating a boot.scr)
6. file bug against flash-kernel package to add device

Examples:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=839595 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=876774

Sometimes I also encounter dead ends: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=906268

Hi everybody!

Firstly seeing an SoC vendor reach out directly about enabling their HW in Debian seems great to me!

I have been doing a little bit of this work in the past, asking the Debian developers to add support for certain devices I had been working with. It was a very slow process, often years between me establishing contact and an actual release supporting a

device.

It turned out that I didn't always have the time to follow through, and also sometimes encountered bugs specific to the more obscure components like debian-installer.

I'd like to make progress with this approach again, eventually. Especially with SoC vendors supporting upstream Linux well, such as NXP (which I work with a lot) - but also Renesas (my colleague tells me), support is quite possible.
So @Huynh, I'd be happy to assist / answer some questions.

However note I am not part of the Debian project.
I don't know if joining makes sense, I don't know if the Debian project would like to incorporate some developers who specifically would collaborate to support certain vendors in Debian.....
Just - there are things outsiders cannot do - like maintaining a "Blend" e.g.

Sincerely
Josua Mayer

I’m from Renesas Electronics Corporation,

Welcome to Debian! In case your company would like to help out Debian,
please review our suggestions for ways that companies can contribute:

https://www.debian.org/intro/help#organizations

My group is developing to support running Debian OS on our devices,
also for getting ARM System Ready IR certificate.

It would be great to see Renesas contribute to the Debian ARM ports,
some resources for the ports are at the links below.

https://wiki.debian.org/Arm64Port
https://www.debian.org/ports/arm/
https://lists.debian.org/debian-arm/

This document about creating new ports should also apply to
contributing to the existing Debian ports to ARM.

https://wiki.debian.org/PortsDocs/New

I recognize that the latest Debian 11 (Bullseye) has the kernel which
do not enable support for Renesas platform.

Please refer to the Debian Linux kernel team documentation for how to
submit patches enabling this support in Debian unstable. I don't know
what the policy is for enabling Linux kernel config options in stable,
but it should be documented somewhere in the documentation here:

https://kernel-team.pages.debian.net/kernel-handbook/

Can you help me to enable those configs, also support the official
release version of Debian Live Installer ISO which support Renesas
platform?

Debian does not yet support the ARM architecture at all with our live
images, please contact the Debian Live Team about that. Currently the
live images for the future Debian bookworm release are not being built,
but that may change before the final release.

would collaborate to support certain vendors in Debian.....
Just - there are things outsiders cannot do - like maintaining a
"Blend" e.g.

You don't need to be a Debian member to contribute to Debian nor to
maintain a Debian blend, everyone is welcome to do that. All package
uploads will need to go via a sponsor or the maintainers though.
Usually a "Blend" isn't needed to support specific hardware, as the
support just goes into the existing hardware support packages like u-boot/linux/mesa. Blends are more for specific areas of use-cases like
gaming or medicine or astronomy.
