Hi.

I'm currently fumbling around in the dark, trying to find a kernel which I can use to compile the powervr drivers, as well as with rpmsg support. Ideally the rpmsg should already be in the kernel, but I can see that this might be hard, and cherry picking is an ok solution. I'm wondering if one of the ti landing team kernels might be suitable for this, and if one of these is considered a stable kernel?

Last kernel I looked at was the LEB 3.1.5+ kernel, release-linux-2011-12, which worked fine for compiling the pvr drivers from rsalveti, but didn't contain rpmsg drivers. When I tried the release-linux-2012-01 kernel, 3.2.0+, it could compile the powervr driver, but didn't contain the rpmsg drivers and didn't actually run, as I got the message 'coherent pool not initialized' from the kernel when trying to allocate for the ehci-omap.

The kernel will be run on a device with an omap4460 if this is of interest.

I would really appreciate your help on this, as I feel quite lost in all the different branches and tags which reside in the different linaro kernels, so a repo with a stable commit would really help. As most rpmsg implementations I have seen follows the 3.2 kernel, that would really be preferable if I need to cherry pick, but if not I don't really care if it's 3.1 or 3.2.

If you have any questions, please do not hesitate to ask them.

Best regard Martin Ertsas
