Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> LoongArch: Increase ARCH_DMA_MINALIGN up to 16<br /> <br /> ARCH_DMA_MINALIGN is 1 by default, but some LoongArch-specific devices<br /> (such as APBDMA) require 16 bytes alignment. When the data buffer length<br /> is too small, the hardware may make an error writing cacheline. Thus, it<br /> is dangerous to allocate a small memory buffer for DMA. It&amp;#39;s always safe<br /> to define ARCH_DMA_MINALIGN as L1_CACHE_BYTES but unnecessary (kmalloc()<br /> need small memory objects). Therefore, just increase it to 16.
