Hi all, version 7 of "CPUs capacity information for heterogeneous systems" patchset [1] (please refer to previous postings to get some context). A few changes from v6: - rebase on top of mainline (4.8-rc5) - some ACKs collected - changelogs fixes - use cpuinfo.max_freq - add delayed work to unregister notifier Patches high level description: o 01/08 introduces documentation for the new optional DT binding o [02-06]/08 add cpu-capacity attribute to TC2, Juno and Juno r2 DTs and provide parsing of such information at boot time o [07-08]/08 introduce sysfs attribute In case you would like to test this out, I pushed a branch here: git://linux-arm.org/linux-jl.git upstream/default_caps_v7 This branch contains additional patches, useful to better understand how CPU capacity information is actually used by the scheduler. These patches also form the basis for Morten/Dietmar's "Clean-ups and asymmetric cpu capacity support" series [2] (and the EAS stack in general).
