No, unfortunately I am evidently ahead of the times ^^ -- your patch does not fix my bug...
I have a valid DT table, it's just not on a SoC that has big.LITTLE. mpidr_cpuids_count is 0 and nr_cpu_ids is 2 ... Instead of using DT being there or not it seems you need to test something more to do with it being on a big.LITTLE or not... -Andy On 11 June 2013 21:23, Jon Medhurst (Tixy) <t...@linaro.org> wrote: > On Tue, 2013-06-11 at 21:08 +0800, Andy Green wrote: >> I see...
