This patchseries aims at fixing and improving CPU hotplug support on Qualcomm platforms. First three patches are the fixes for the LMH support in the cpufreq driver. The last patch adds support for lightweight offline() and online() callbacks which are used instead of exit() and init() each time the CPU is put offline or back online. Patches 1-3 being pure simple fixes can be applied during the -rc stage, while patch 4 is targeting next development cycle Changes since v3: - Readd throttled_freq calculation disappearing from the third patch. Changes since v2: - Point Fixes tag from the first patch to the correct commit - Replace huge patch 2 with one-liner thanks to being able to use policy->related_cpus instead of policy->cpus Changes since v1: - Update commit message for the first patch to describe why dropping affinity hint is required (before calling free_irq()), - Fixed commit message for the second patch to include messages generated using the mainline kernel w/o additional patches, - Changed third patch to use dev_warn_ratelimited(), - Reworked last patch to move request_irq/free_irq to online()/offline() to make sure that the IRQ isn't left enabled after the CPU has been put offline. Dmitry Baryshkov (4): cpufreq: qcom-hw: drop affinity hint before freeing the IRQ cpufreq: qcom-hw: fix the race between LMH worker and cpuhp cpufreq: qcom-hw: fix the opp entries refcounting cpufreq: qcom-hw: provide online/offline operations drivers/cpufreq/qcom-cpufreq-hw.c | 45 ++++++++++++++++++++++++++----- 1 file changed, 38 insertions(+), 7 deletions(-) -- 2.35.1
