Subject: [PATCH] Add support for kernel module compression
|
||||
|
||||
This adds the support for kernel module compression in
|
||||
pesign-obs-integration infrastructure. The kernel-binary spec needs
|
||||
to pass $BRP_PESIGN_COMPRESS_KERNEL for enabling the compression.
|
||||
Currently only "xz" is supported.
|
||||
|
||||
pesign-gen-repackage-spec received a new option --compress, which is
|
||||
passed from pesign-repackage.spec, where brp-99-pesign enables it per
|
||||
the variable above.
|
||||
|
||||
With --compress option, pesign-gen-repackage-spec script just
|
||||
compresses the kernel object at the last repackaging phase.
