| help | |
| This provides support for reading images from EROFS filesystem. | |
| EROFS (Enhanced Read-Only File System) is a lightweight read-only | |
| file system for scenarios which need high-performance read-only | |
| requirements. | |
| It also provides fixed-sized output compression support, which | |
| improves storage density, keeps relatively higher compression | |
| ratios, which is more useful to achieve high performance for | |
| embedded devices with limited memory. | |
| config FS_EROFS_ZIP | |

| help | |
| Enable fixed-sized output compression for EROFS. | |
| If you don't want to enable compression feature, say N. | |
| config FS_EROFS_ZIP_DEFLATE | |
| bool "EROFS DEFLATE compressed data support" | |
| depends on FS_EROFS_ZIP | |
| select ZLIB | |
| help | |
| Saying Y here includes support for reading EROFS file systems | |
| containing DEFLATE compressed data. It gives better compression | |
| ratios than the default LZ4 format, while it costs more CPU | |
| overhead. | |
| DEFLATE support is an experimental feature for now and so most | |
| file systems will be readable without selecting this option. | |
| If unsure, say N. |
