There seems to have been a lot of refactoring of drivers/clk/{shmobile,renesas}
since 4.4 so I'm not sure how this should be fixed.

Current upstreamed RZ/G1M clock driver uses the new Renesas CPG/MSSR clock driver frame work.
Backporting requires lot of refactoring of drivers/clk/{shmobile,renesas}.
So I don't think backporting the RZ/G1M clock driver is the right choice.

OK.

However r8a7743( RZ/G1M) is identical to r8a7791(RCar-M2) platform. We ported r8a7743( RZ/G1M) clk driver based on this.
The current patch series, which I submitted is tested with this clk driver.

Then I think I should just make this change:

Subject: CIP: Build essential clock driver for Renesas RZ/G1 platforms

In mainline, clk-rcar-gen2 is selected by CONFIG_CLK_RCAR_GEN2 but
here there is no such common config symbol and we need to select
it for each platform.

The 0.9.1 release box of B@D has been successfully imported into Windows
10 and both a QEMU and BBB health check have been run on that virtual machine.
This setup also works when provisioning a box from a clone of the git repository.

The steps to get B@D running on Windows 10 are as follows:

- Install the guest additions `vagrant plugin install vagrant-vbguest`
- Install rsync/ssh/git in cygwin.
- core.autocrlf=input is needed in the git settings for the scripts to
run under the Debian of the virtual machine.
- Once the vm is up then in virtualbox add a USB filter for the FTDI device.
- For kernelci access you need to use either Firefox or Chrome - the Microsoft
browsers will not work.
- You may need the vagrant scp command (if you wish to copy other files
onto the VM) if so -
vagrant plugin install vagrant-scp
- setup mybbb.dat to use the IP address of the VM rather than that of
the host.

The wiki has been updated to document these steps.

Btw, instead of having yet another setup.sh, you may want to have a look
at kas [2]. There is no release yet (next week, hopefully), but it is
fairly mature. Moreover, you can build inside Docker, removing most of
the host dependencies. We are using this now with both Yocto and Isar
projects, often in layered ways [3] that enable reuse.

Yesterday I managed to build the qemux86-64 meta layer using the following
kas project configuration. Could you check it please?

https://gitlab.com/cip-playground/project-x/commit/de611ae06040f6e426d3c5d1b77eb20b4af31a19

Looks good. You should just set version to 0.10 and use yesterday's
release. You can pull the corresponding docker image from
https://hub.docker.com/r/kasproject/, and there should be a pip package
as well soon.

That was fast. I was using the next branch and built the Dockerfile included in kas.

I had to create a daemon.json to set overlay2 as the storage driver, pass the USER_ID variable,

We should probably suggest to call "USER_ID=$(id -u) docker run ..." -
it there a way to achieve this in an easier way? Still learning all this
docker stuff.

I was using the -e flag:
docker run -e USER_ID=`id -u $USER` -it kas sh

Err, right, that's what I meant.

volume mount the project-x folder and manually set the proxy settings (for some reason using
build-args didn't work for me).

Hmm, they should, I'm using them for builds all the time (along with
corresponding settings for the docker daemon).

Are you sure you didn't set them somewhere else in the docker configuration?
As far as I can see the Dockerfile is not using any ARG instruction at all.

Yes, I'm sure. I've just written the doc for a product SDK, and that
uses no further settings as well, see
https://github.com/siemens/meta-iot2000/blob/jan/staging/README.md#docker-build.

hmmm, I think that you made a small mistake in the kas documentation [1]. You wrote that
http_proxy should be passed as a build-arg but as I said there is no ARG instruction in the
Dockerfile.

No, also that works: It won't leave the proxy settings behind in the
image, but it allows to build it behind a proxy.

We don't want to generate "proxified" images that will then only work in
a very specific environment. We are coming from there, it was a mess.
The image we have now can be fed into a CI build, and you only need to
configure the specific proxies at project level. Works nicely with our
corporate gitlab infrastructure.

Jan

In the meta-iot2000 link you are setting the proxy variables as environment variables using
'docker run -e http_proxy=$http_proxy' which does work indeed.>

Hi Jan,

Hello Daniel,

From: Daniel Sangorrin [mailto:daniel.sangorrin@...]
Sent: 11 July 2017 02:04

Hi all,

# Chris, I wanted to discuss about the U-Boot policy last night during the
online meeting but somehow I missed the URL change.

Sorry we missed you!

We have had some discussions about U-boot for a while but I would like to
achieve some consensus about what we should do about it.

U-boot is a rather big project that resembles the Linux kernel in some
aspects. For example, unlike generic software (e.g. openssh) a big bunch of
its code is hardware dependent. U-boot releases have a cadence of 2
months (for example v2017.07 was released on Mon, 10 July 2017) but there
is no LTS project as far as I know. The closest to an LTS project that I know of
is the U-Boot packages maintained by distros (e.g. Debian) , which seem (see
changelog [1]) to focus on bug fixing and backporting new hardware support.

I'm going to throw some mud at the wall and see what sticks after our
discussion.

Thank you for resuming the conversation.

1. Should we focus on supporting our reference boards only?
Sangorrin: yes.

Chris: Agreed.

2. Should all reference boards use the same source code base line?
Sangorrin: yes, unless the porting effort for a board is too complicated in
which case we are better off providing a separate repo.

Chris: Ideally yes, but currently I don't think all of the reference boards are in mainline u-boot, and I'm not sure CIP should be doing/funding the upstreaming of the reference boards. This should ideally be done by the board vendors.
One option could be to create a cip-u-boot repo and manually add support for the different boards, but obviously this work would need to be repeated if we were ever to upgrade the base u-boot version for future CIP releases.

3. In case the answer to question 2 is 'yes': what's the base line that we
should use?
Sangorrin: the source code from a Debian u-boot package that better
supports our current reference boards and CIP kernel.

4. Should we focus on backporting security/bug fixes, or new HW support?
Sangorrin: No. I think that we should only make sure that our reference
boards are able to boot the CIP kernel during its lifetime.

Chris: Given the resources and aims of the project, I think you are right. We should just make sure that the platform boots. Many production devices probably won't use u-boot in the field anyway, at least not our version.

5. Should we upstream our fixes?
Sangorrin: Yes. For future maintainability and as a quality assurance step. But
while the patches are getting accepted we should also have our own repos
on gitlab's playground.

Chris: Yes, this will help us in the future if we are to upgrade versions.

6. What functionality in U-Boot is important for us?
Sangorrin: network support for tftpboot would be great to have. Specially for
debugging and for the CI tests.

Chris: In addition, being able to boot from mmc/usb will help with demo work.

Kind regards, Chris

Please add your answers!

Thanks,
Daniel

Finally, for U-boot I need repositories to fetch the sources.
Should we have separate repositories for each board? For example:
https://gitlab.com/cip-playground/u-boot-iwg20m
https://gitlab.com/cip-playground/u-boot-cyclonev

If the consensus is to use different u-boot versions/repos for each
platform, (rather than push vendors to add support upstream), then this

approach makes sense.

However, perhaps we should try and use exiting repositories provided
by the vendors, rather than CIP create and maintain them. If we start

hosting these repositories we will have to continue to maintain them
forever.

Of course, the downside of using externally maintained repositories is
that support may end at any time. Perhaps bringing this

ownership/maintenance into the CIP project is something we want to
do/fund.


I'm not sure what maintenance is required for u-boot

Kind regards, Chris

Thanks,
Daniel

Looks good. You should just set version to 0.10 and use yesterday's
release. You can pull the corresponding docker image from
https://hub.docker.com/r/kasproject/, and there should be a pip package
as well soon.

That was fast. I was using the next branch and built the Dockerfile included in kas.

I had to create a daemon.json to set overlay2 as the storage driver, pass the USER_ID variable,

We should probably suggest to call "USER_ID=$(id -u) docker run ..." -
it there a way to achieve this in an easier way? Still learning all this
docker stuff.

I was using the -e flag:
docker run -e USER_ID=`id -u $USER` -it kas sh

Err, right, that's what I meant.

volume mount the project-x folder and manually set the proxy settings (for some reason using
build-args didn't work for me).

Hmm, they should, I'm using them for builds all the time (along with
corresponding settings for the docker daemon).

Are you sure you didn't set them somewhere else in the docker configuration?
As far as I can see the Dockerfile is not using any ARG instruction at all.

Yes, I'm sure. I've just written the doc for a product SDK, and that
uses no further settings as well, see
https://github.com/siemens/meta-iot2000/blob/jan/staging/README.md#docker-build.

Does it still make a difference to set BB_NUMBER_THREADS and
PARALLEL_MAKE? I'm seeing full CPU usage without it as well. I'm always
looking for reasonable defaults we can set (?=) from kas automatically.
BB_DISKMON_DIRS should likely be included, I was adding it as well already.

You know better than me ;)
I just checked the latest ref manual and apparently OE automatically sets them up.

Ah, good to know. The parallel things, or even also DISKMON?
