Hi all, This patch set is a continuation of my previous work, which aimed to add Energy Model to all devices. This series is a follow up for the patches which got merged to v5.9-rc1. It aims to change the thermal devfreq cooling and use the Energy Model instead of private power table and structures. The new registration interface in the patch 3/5 helps to register devfreq cooling and the EM in one call. There is also another improvement, patch 2/5 is changing the way how thermal gets the device status. Now it's taken on demand and stored as a copy. The last patch wouldn't go through thermal tree, but it's here for consistency. The patch set is based on current next-20201118, which has new EM API in the pm/linux-next tree. changes: v2: - renamed freq_get_state() and related to perf_idx pattern as suggested by Ionela v1 [2] Regards, Lukasz Luba [1] https://lkml.org/lkml/2020/5/11/326 [2] https://lore.kernel.org/linux-pm/20200921122007.29610-1-lukasz.luba@arm.com/ Lukasz Luba (5): thermal: devfreq_cooling: change tracing function and arguments thermal: devfreq_cooling: get a copy of device status thermal: devfreq_cooling: add new registration functions with Energy Model thermal: devfreq_cooling: remove old power model and use EM drm/panfrost: Register devfreq cooling and attempt to add Energy Model drivers/gpu/drm/panfrost/panfrost_devfreq.c | 2 +- drivers/thermal/devfreq_cooling.c | 434 ++++++++++---------- include/linux/devfreq_cooling.h | 39 +- include/trace/events/thermal.h | 19 +- 4 files changed, 259 insertions(+), 235 deletions(-)
