Subject: [PATCH 4/4] arm64: dts: qcom: sdm670: add frequency profile
Date: Mon, 24 Jul 2023 17:42:14 -0400 [thread overview]
Message-ID: <20230724214209.208699-10-mailingradian@gmail.com> (raw)
In-Reply-To: <20230724214209.208699-6-mailingradian@gmail.com>
Add the coefficients for the CPU frequencies to aid in frequency
scaling.
Profiling setup:
- freqbench (https://github.com/kdrag0n/freqbench)
- LineageOS kernel, android_kernel_google_msm-4.9
- recommended configuration options by freqbench
- disabled options that require clang or 32-bit compilers
- mmc governor switched from simple_ondemand to powersave
