Always use the standard Linux DMA APIs ( dma_alloc_coherent() , dma_map_single() ) to ensure the memory allocations map properly within the physical bounds defined by the platform's hardware limitations. 3. Kernel Panics: Unaligned Accesses
Pointers increase from 32-bit to 64-bit, changing the structure alignment in memory. msm8953 for arm64 driver
The MSM8953 is built on a 14nm FinFET process, making it highly power-efficient. Unlike heterogeneous big.LITTLE architectures, it features a symmetric multi-processing (SMP) design: Always use the standard Linux DMA APIs (
This output displays the operational status of crtcs, encoders, connectors, and plane configurations, simplifying troubleshooting for broken MIPI-DSI panel initializations. The MSM8953 is built on a 14nm FinFET
| Feature | Downstream (4.4/4.9) | Mainline (6.x) | |--------|----------------------|----------------| | GPU | Full msm (kgsl) | Freedreno (works) | | Display | Full | Partial | | Audio | Full ALSA | Minimal | | Modem | Yes (rmnet, qmi) | No | | WiFi/BT | Yes (wcnss) | No / partial | | Camera | Yes | No | | PMIC | Full | Basic reg/hwmon | | Stability | High (but legacy) | Medium (basic I/O works) |
When building an ARM64 kernel for MSM8953, you need these essential drivers:
Adreno 506 graphics processing unit with 64-bit addressing.
