In the coresight CPU debug document it suggests to use 'echo' command
to set latency request to /dev/cpu_dma_latency so can disable all CPU
idle states, but in fact this doesn't work.
This is because when the command 'echo' exits, it releases the device
node's file descriptor and the kernel releas

Hello Mr Chehab,
Thanks for the comments.
I have modified dtv_property_process_set and
also added documentation.
Please let me know if any further modifications required.

arch_kexec_kernel_*() and arch_kimage_file_post_load_cleanup can now be
duplicated among some architectures, so let's factor them out.

This is the third round of implementing kexec_file_load() support
on arm64.[1]
Most of the code is based on kexec-tools (along with some kernel code
from x86, which also came from kexec-tools).
This patch series enables us to
* load the kernel, Image, with kexec_file_load system call, and
* o
This function, being a variant of walk_system_ram_res() introduced in
commit 8c86e70acead ("resource: provide new functions to walk through
resources"), walks through a list of all the resources of System RAM
in reversed order, i.e., from higher to lower.
It will be used in kexec_file implementati
This is a basic purgatory, or a kind of glue code between the two kernels,
for arm64.
Since purgatory is assumed to be relocatable (not executable) object by
kexec generic code, arch_kexec_apply_relocations_add() is required in
general. Arm64's purgatory, however, is a simple asm and all the refer
message[] field won't be part of the definition of mz header.
This change is crucial for enabling kexec_file_load on arm64 because
arm64's "Image" binary, as in PE format, doesn't have any data for it and
accordingly the following check in pefile_parse_binary() will fail:
chkaddr(cursor,
The "Image" binary will be loaded at the offset of TEXT_OFFSET from
the start of system memory. TEXT_OFFSET is determined from the header
of the image.
Regarding kernel signature verification, it will be done through
verify_pefile_signature() as arm64's "Image" binary can be seen as
in PE format.

load_other_segments() sets up and adds all the memory segments necessary
other than kernel, including initrd, device-tree blob and purgatory.
Most of the code was borrowed from kexec-tools' counterpart.
