I have digested the review comments so far, including a recent offlist chat with with Lorenzo Pieralisi around the debatable PSCI changes. More or less I have a plan for how to move forward. However, to avoid re-posting non-changed patches over and over again, I decided to withhold the more debatable part from this v9, hence this is not the complete series to make things play. In v9, I have just included the trivial changes, which are either already acked/reviewed or hopefully can be rather soon/easily. My hope is to get this queued for v4.20, to move things forward. I know it's late, but there are more or less nothing new here since v8. Kind regards Ulf Hansson Changes in v9: - Collect only a subset from the changes in v8. - Patch 3 is new, documenting existing genpd flags. Future wise, this means when a new genpd flag is invented, we must also properly document it. - No changes have been made to the patches picked from v8. - Dropped the text from v8 cover-letter[1], to avoid confusion. When posting v10 (or whatever the next version containing the rest becomes), I am going re-write the cover-letter to clarify, more exactly, the problems this series intends to solve. The earlier text was simply too vague. [1] https://lwn.net/Articles/758091/ Changes in v8: - Added some tags for reviews and acks. - Cleanup timer patch (patch6) according to comments from Rafael. - Rebased series on top of v4.18rc1 - it applied cleanly, except for patch 5. - While adopting patch 5 to new genpd changes, I took the opportunity to improve the new function description a bit. - Corrected malformed SPDX-License-Identifier in patch20. Changes in v7: - Addressed comments concerning the PSCI changes from Mark Rutland, which moves the psci firmware driver to a new firmware subdir and change to force PSCI PC mode during boot to cope with kexec'ed booted kernels. - Added some maintainers in cc for the timer/nohz patches. - Minor update to the new genpd governor, taking into account the state's poweroff latency while validating the sleep duration time. - Addressed a problem pointed out by Geert Uytterhoeven, around calling pm_runtime_get|put() for CPUs that has not been attached to a CPU PM domain. - Re-based on Linus' latest master.
