If I read this correctly, WR ported RT to 2.6.34.

Anyone out there to confirm?

Yes, it's true.

Ok, where do I download this from?

there is a open source version of windriver kernel:
git://git.pokylinux.org/linux-2.6-windriver
please try "preempt_rt" branch.

Thanks.

Just for clarity, does this mean you also have a non-open-source version of the WR Linux Kernel?

Nope, there is the kernel that ships with the Wind River Linux product, but it is just as open source as any other maintained Linux kernel. The source is available
with every copy of the product at release, and is also made available through other channels as appropriate.

I maintain both the poky, and Wind River commercial kernel, so feel free to contact me with any questions, technical or not.

Cheers,

Bruce

Please do NOT try this branch. It is only being updated now and is not up to date.

Bruce,

Is there now an up to date version of the 2.6.34 windriver RT patches that we can access?

Thanks,

Frank Rowand

Hi Frank,

There will be one shortly, this is being worked on several fronts. I have an update to the yocto branches that brings it up to date with to capture some stability fixes from -tip and other sources. There are also other efforts to fixup the series to work with a stock 2.6.34 that should be ready in the not to distant future. We are trying to hit the middle ground of cleaning up the presentation of this, but not waste effort by working through changes that are already being done as the -rt patch is updated to newer kernels.

What currently is in the yocto preempt_rt branch will boot, but still has a few things I need to change (I'm held up deciding if doing a non-fastforward merge is acceptable:)

Cheers,

Bruce

Because it isn't official from the RT maintainers in any way shape or form. It isn't applied on top of a stock 2.6.34 kernel context and has been modified to work with a particular feature mix, and per board deployment. In other words, the source comes along with our product, but outside of that it isn't designed to be a pristine upstream, or deployed outside of a specific configuration.

Hope that helps.
