When writing or porting drivers for this SoC, you aren't just dealing with the CPU; you are interfacing with several proprietary subsystems: Requires the msm or freedreno DRM driver. Hexagon DSP: Managed via the Quic (Qualcomm) Framework.
To run a stable ARM64 operating system on the MSM8953, several foundational drivers must coordinate smoothly: Pinctrl and GPIO (TLMM)
#ifdef CONFIG_ARM64 pr_info("MSM8953 ARM64 driver loaded on 64-bit kernel\n"); #else pr_info("MSM8953 driver loaded on non-ARM64 kernel (check config)\n"); #endif return 0;
Qualcomm SoCs are unique in that they treat the modem as a separate processor.
The effectiveness of MSM8953 on ARM64 relies on several critical driver families: Display and GPU: The Adreno 506 uses the MSM DRM/KMS
The driver requested a resource (like a GPIO or regulator) that hasn't initialized yet. The Linux kernel will automatically re-queue your probe function once dependencies are met. Conclusion
Adreno 506 graphics processing unit with 64-bit addressing.
