Subject: [Patch 0/6] CPPC_CPUFREQ improvements for Tegra241
Date: Tue, 18 Apr 2023 17:04:53 +0530 [thread overview]
Message-ID: <20230418113459.12860-1-sumitg@nvidia.com> (raw)
This patch series contains improvements and changes needed to get a
stable value of current CPU frequency from "cpuinfo_cur_freq" sysfs
node in Tegra241 SoC. All the CPU's in Tegra241 implement the ARM
Activity Monitor Unit (AMU). On reading the sysfs node, the frequency
value is re-constructed using AMU counters.
Sanjay Chandrashekara (1):
cpufreq: use correct unit when verify cur freq
Sumit Gupta (5):
cpufreq: CPPC: make workaround apply code generic
irqchip/gicv3: Export arm_smccc_get_soc_id_xx funcs
cpufreq: CPPC: update sampling window for Tegra241
arm64: cpufeature: Export get_cpu_with_amu_feat func
cpufreq: CPPC: use wq to read amu counters on target cpu
