Hi,

 

in order to increase the visibility of the work done in Gitlab I suggest one of these two actions:

* Create a mailing list for development notifications where we can send the notifications of the commits made in gitlab, including the diffs.

* Send the notifications to this mailing list and let users filter them.

 

I do not expect heavy traffic as long as we do not include Ben's repo.

 

In the same line, I suggest to do the same with IRC, expecting limited traffic.

 

Best Regards

Hi Daniel,

Thanks for letting me know. The correct URL is

https://www.kernel.org/pub/linux/kernel/people/wagi/cip-rt/4.4/

Sorry, but there is no " patch-4.4.112-cip18.xz" on that URL either.

Argh :) This should read patch-4.4.112-cip18-rt11.patch.xz

Also shouldn't we have 3 patches? lts + cip + rt

I just create the patches on top of the CIP version.

Oh, I see. the vanilla linux url (linux-4.4.tar.xz) confused me.
Then, what we should use is this, right?:
https://git.kernel.org/pub/scm/linux/kernel/git/bwh/linux-cip.git/snapshot/linux-cip-4.4.112-cip18.tar.gz
https://www.kernel.org/pub/linux/kernel/people/wagi/cip-rt/4.4/patch-4.4.112-cip18-rt11.patch.xz

Yes. these are the right URLs.

The scripts for
this are the ones we use for the stable-rt trees. I don't know the
patches are useful or not. I don't mind dropping the patch services if
no one needs it. Neither Greg nor Ben are creating patch releases so
doing the cip-rt patches seems like a waste of time.

Personally, I don't mind if you stop releasing the patches. I have tested
the cip-rt kernel from your git tree and so far I didn't have problems
with long real-time latencies. I also confirmed that meltdown is fixed.

Right, I'll stop doing the patches.

Good to hear that the cip-rt works for you!

Thanks,
Daniel

From: Simon Horman <horms+renesas@...>

Add per-Generation fallback bindings for R-Car SoCs.

This is in keeping with the compatibility string scheme is being adopted
for drivers for Renesas SoCs.

Also, improve readability by listing the rmobile fallback compatibility
string after the more-specific compatibility strings they provide a
fallback for.

From: Simon Horman <horms+renesas@...>

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and Gen 3. But beyond that it's not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7790 is older than r8a7791 but that doesn't imply that the latter is a
descendant of the former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme is being adopted for
drivers for Renesas SoCs.

Also:
* Deprecate renesas,i2c-rcar. It seems poorly named as it is only
compatible with R-Car Gen 1. It also appears unused in mainline.
* Add some text to describe per-SoC bindings

I'll add here another list, since these people might be interested in
this thread/topic.

thats a fine idea you might want to look into

http://downloads.yoctoproject.org/releases/yocto/yocto-2.4.1/toolchain/

for prebuilt SDKs

Hi Team,

How can I generate Yocto generated SDK as .deb package? Currently it is in
the form of installable shell script but I want to generate it as .deb
package so that I can directly install it on my Ubuntu VM using "apt-get"
command.

Is this supported? Any documentation?

Regards,
Gaurang
