Subject: [PATCH v1 0/2] zboot: enable kexec_load for zboot kernel images
Date: Thu, 14 Sep 2023 16:49:58 +0800 [thread overview]
Message-ID: <20230914085000.17982-1-dyoung@redhat.com> (raw)
The current kexec-tools only support kexec_file_load for zboot kernel
images on arm64.
This series tweak a bit of the code so kexec_load can also load zboot
images on both arm64 and loongarch.
V1 changes:
- dup the kernel_fd so that kexec_file_load can work since slurp_fd
will close it.
- code clean up.
