Subject: [PATCH 07/10] arm64: dts: qcom: sm8550: Update EAS properties
From: Xilin Wu <wuxilin123@...il.com>
The original values provided by Qualcomm appear to be quite
inaccurate. Specifically, some heavy gaming tasks could be
improperly assigned to the A510 cores by the scheduler, resulting
in a CPU bottleneck. This update to the EAS properties aims to
enhance the user experience across various scenarios.
The power numbers were obtained using a Type-C power meter, which
was directly connected to the battery connector on the AYN Odin 2
motherboard, acting as a fake battery.
It should be noted that the A715 cores seem less efficient than the
A710 cores. Therefore, an average value has been assigned to them,
considering that the A715 and A710 cores share a single cpufreq
domain.
