Has any luck in using the device trees (dtb files) on arm machines? Things do not seem to be working with the tegra-trimslice.dtb and CONFIG_ARM_APPENDED_DTB=y for me.
I have been looking at Red hat Bug 741325 (ARM fc14 kernels does not provide hardware perf counter support). I suspect the reason that performance monitoring hardware is not working on my trimslice because it isn't using a device tree. The performance monitoring hardware is never getting registered (https://bugzilla.redhat.com/show_bug.cgi?id=741325#c18). I have made a tegra-trimslice.dtb, appended it to the vmlinuz file (suppose to work kernel built with CONFIG_ARM_APPENDED_DTB=y in the config file), done a mkimage on the resulting concatenated file. and attempted to boot the machine. However, it seem to hang right after "Staring kernel ..." message. -Will _______________________________________________ arm mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/arm
