However for Ubuntu, there's not quite yet anything rpmsg-based that's workable to give him mm decode (it seems to be that he's interested in) that will provide userland pieces he can have as a normal mortal as well. Rob Clark is working on something that should bear fruit soon, Nice guys will provide matching Ubuntu pieces and TILT will integrate it into our tracking. Until then tilt-3.1 + Ubuntu packages already there seems the best choice to getting something known to work end-end quickly. Since it integrates to gstreamer already when he upgrades to rpmsg-based solution (userland too) it should hopefully be transparent. -Andy The reason we want rpmsg is to get h264 endcoding and decoding using gstreamer elements. I'm not sure if gst-ducati works with syslink as well? Andy is right that it is mm decode/encode I am interested in. So if I have understood you right: For the time being, I should use tilt-3.1 with syslink and gst-ducati (or some other gst element?) to get mm h264 encoding/decoding working on the omap. And when rpmsg is in a stable upstream/tilt kernel, I can switch to that and still use gst-ducati? - Martin ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

Linux kernel with rpmsg and possibility for compiling powervr drivers
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 ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
