Just a note on this patch together with the patch that cleaned up sun7i_defconfig based on sun4i: Has anyone done some performance measurements with these configuration changes? When I compile a kernel with this cleaned up configuration, I see a small performance decrease in file server transfer speeds (samba writes were around 30MB/s with the old kernel configuration and went down to 25-26MB/s with the streamlined configuration). Because of the amount of changes, it's probably hard to track down and I didn't do extensive tests to bisect this. But is it possible that there is something missing in the configuration that has an impact on performance on A20 devices? -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
