When the data buffer length\nis too small, the hardware may make an error writing cacheline. Thus, it\nis dangerous to allocate a small memory buffer for DMA. It's always safe\nto define ARCH_DMA_MINALIGN as L1_CACHE_BYTES but unnecessary (kmalloc()\nneed small memory objects). Therefore, just increase it to 16.\n\ud83d\udccf Published: 2025-04-16T14:12:08.317Z\n\ud83d\udccf Modified: 2025-04-30T09:33:03.646Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/f39af67f03b564b763b06e44cb960c10a382d54a\n2. https://git.kernel.org/stable/c/279ec25c2df49fba1cd9488f2ddd045d9cb2112e\n3. https://git.kernel.org/stable/c/1d0def2d1658666ec1f32c9495df60e7411e3c82\n4. https://git.kernel.org/stable/c/bfff341cac7c650e6ca8d10503725992f5564d0f\n5. https://git.kernel.org/stable/c/8b82aea3666f8f2c78f86148d78aea99c46e0f82\n6. https://git.kernel.org/stable/c/4103cfe9dcb88010ae4911d3ff417457d1b6a720", "creation_timestamp": "2025-04-30T10:13:29.000000Z"}]}
