Subject: [PATCH 0/5] arm64: zboot support
Date: Fri, 5 May 2023 10:54:32 +0800 [thread overview]
Message-ID: <20230505025438.11943-1-piliu@redhat.com> (raw)
As more complicated capsule kernel format occurs like zboot, where the
compressed kernel is stored as a payload. The straight forward
decompression can not meet the demand.
As the first step, on aarch64, reading in the kernel file in a probe
method and decide how to unfold the content by the method itself.
The new designed probe interface returns two factors:
1. the parsed kernel_buf should be returned so that it can be used by
the image load method later.
2. the final fd passed to sys_kexec_file_load, since aarch64 kernel can
only work with Image format, the outer payload should be stripped and a
temporary file of Image should be created.

kexec: Adding missing free for kernel_buf
arm64/zImage: Remove unnecessary allocation for
kernel_uncompressed_buf
arm64: change the prototype of image probe function
arm64: Scatter the reading of kernel file into each probe
arm64: add support for zboot image
