The MSM8953 often operates in high-throughput environments (such as camera pipelines or networking). Drivers must never block the CPU inside an Interrupt Service Routine (ISR).
A very low-level but driver for platform stability is the Interconnect driver.

Commenting complex register-level interactions within the source.
To overcome the challenges and develop high-quality drivers for the MSM8953 SoC on the ARM64 architecture, follow these best practices: leveraging the ARM64 memory model
Locate for arm64 driver development.
Eight Cortex-A53 cores operating in a single cluster using Energy Aware Scheduling (EAS). Drivers must handle inter-processor communication (IPC) without waking up sleeping cores unnecessarily.
