|
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.

|
|
Enable fixed-sized output compression for EROFS.
|

If you don't want to enable compression feature, say N.

bool "EROFS DEFLATE compressed data support"

depends on FS_EROFS_ZIP

|
|
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.
