Hi,
v4->v5 - I've applied Viresh's remaining suggestion and Acked-by/s - v4 can be found at [4] - v5 is based on linux-next 20200828
Thank you, Ionela.
--- v3->v4: - addressing Viresh's comments on patches 1/5 and 3/5, and - with his Acked-by applied for the rest of the patches; - v3 can be found at [3], and - this is based on linux-next 20200827.
v2->v3 - v2 can be found at [2] - 1/5 was introduced to check input frequencies to arch_set_freq_scale() as recommended by Rafael - The previous 2/7 was squashed into 1/7 - now 2/5, with additions to the changelog as suggested by Rafael. - The previous 3/7 (BL_SWITCHER handling) was dropped to be handled in a separate patch. This does not change the current functionality. - The previous 4/7 - now 3/5 is simplified as suggested by Viresh. - 3/5 - cpufreq_supports_freq_invariance() replaces cpufreq_sets_freq_scale(). The meaning chosen for cpufreq_supports_freq_invariance() is whether it can set the frequency scale factor, not whether arch_set_freq_scale() actually does. - 4/5 - Change after Catalin's Ack: The changes to arch_set_thermal_pressure() were dropped as they were done in a separate patch. Therefore this patch now has a subset of the previous changes at 5/7 - 5/5 - Change after Catalin's Ack: s/cpufreq_sets_freq_scale/cpufreq_supports_freq_invariance - v3 is based on linux-next 20200814
v1 -> v2: - v1 can be found at [1] - No cpufreq flags are introduced - Previous patches 2/8 and 3/8 were squashed in this series under 1/7, to ensure bisection. - 2/7 was introduced as a proposal for Viresh's suggestion to use policy->cur in the call to arch_set_freq_scale() and is extended to support drivers that implement the target() callback as well - Additional commit message changes are added to 1/7 and 2/7, to clarify that the definition of arch_set_freq_scale() will filter settings of the scale factor, if unwanted - 3/7 disables setting of the scale factor for CONFIG_BL_SWITCHER, as Dietmar suggested - Small change introduced in 4/7 to disable cpufreq-based frequency invariance for the users of the default arch_set_freq_scale() call which will not actually set a scale factor - build issue solved (reported by 0day test) - v2 is based on linux-next 20200716 - all functional tests in v1 were repeated for v2
