-Subject: [PATCH] arm64: swiotlb: Reduce the default size if no ZONE_DMA
- bouncing needed
-
-With CONFIG_DMA_BOUNCE_UNALIGNED_KMALLOC enabled, the arm64 kernel still
-allocates the default SWIOTLB buffer (64MB) even if ZONE_DMA is disabled
-or all the RAM fits into this zone. However, this potentially wastes a
-non-negligible amount of memory on platforms with little RAM.
-
-Reduce the SWIOTLB size to 1MB per 1GB of RAM if only needed for
-kmalloc() buffer bouncing.
