kdump-compressed format supports three compression format, zlib/lzo/snappy.
|
|
|
9ae3a8 |
Currently, only zlib is available. This patch is used to support lzo/snappy.
|
|
|
9ae3a8 |
'--enable-lzo/--enable-snappy' is needed to be specified with configure to make
|
|
|
9ae3a8 |
lzo/snappy available for qemu
