drivers to communicate with the Hexagon DSP via the APR (Asynchronous Packet Router) protocol. 3. Device Tree and Boot Flow
: Includes the Hexagon 546 DSP, X9 LTE modem, and dual image signal processors (ISPs). Mainline Status
: The MSM8953 is considered a "mainline" SoC, meaning basic support is already upstream in the Linux kernel. postmarketOS Wiki kernel/common - Git at Google - Android GoogleSource msm8953 for arm64 driver
To build a kernel with MSM8953 drivers for an ARM64 target, developers typically follow these steps:
: In Linux kernel 6.8+, experimental Rust drivers for Qualcomm SoCs exist. MSM8953 may see Rust-based sensor drivers. drivers to communicate with the Hexagon DSP via
Let’s demonstrate a simple virtual character driver for MSM8953 on ARM64. This logs the CPU architecture at insmod time.
Many users report that rear USB ports fail to charge phones or recognize data if the specialized drivers for the vehicle-specific harness aren't properly initialized. Mainline Status : The MSM8953 is considered a
Here's a simple example of a kernel module that interacts with the MSM8953 processor on ARM64:
