Msm8953 For Arm64 Driver [exclusive] -
Use kernel 4.9 (minimum) with Android common patches. Recommended repo: LineageOS kernel_xiaomi_msm8953 (updated for 64-bit binder).
Recent patches show active upstreaming:
# wcnss_service present in /vendor/bin/hw/ (should be 32-bit) # ensure wlan.ko is built with CONFIG_ARCH_MSM8953=y msm8953 for arm64 driver
The Snapdragon 625 (system-on-chip model MSM8953) is one of the most successful mid-range mobile processors ever produced. Built on a 14nm FinFET process, it features eight ARM Cortex-A53 cores running up to 2.0 GHz, coupled with an Adreno 506 GPU. While originally shipping with 32-bit (AArch32) Android kernels to optimize RAM usage on early devices, its underlying architecture is fully 64-bit (AArch64). Use kernel 4

: Full support for the Adreno 506 was a long-awaited addition, merging in Linux 5.17. The driver code in drivers/gpu/drm/msm/adreno/ treats the A506 largely as a variant of the A5xx family, requiring specific configurations for its maximum clock speed of 650MHz and its unique hardware features.
The community has proven that MSM8953 can happily run Android 14, postmarketOS, and even Armbian (yes, Linux desktop with XFCE) – as long as you respect the driver split. The legendary efficiency of the Snapdragon 625 will live on, powered not by OEMs, but by passionate open-source developers bridging the 32-bit/64-bit divide.
