checkpatch.pl warns about using __attribute__((packed)) in kernel
|
||||
headers: "__packed is preferred over __attribute__((packed))". If one
|
||||
follows that advice it could cause problems in the exported header
|
||||
files, because the outside world doesn't know about this shortcut.
|
||||
|
||||
For example busybox will fail to compile:
|
||||
CC miscutils/ubi_attach_detach.o
|
||||
In file included from miscutils/ubi_attach_detach.c:27:0:
|
||||
/usr/include/mtd/ubi-user.h:330:3: error: conflicting types for ‘__packed’
|
||||
/usr/include/mtd/ubi-user.h:314:3: note: previous declaration of ‘__packed’ was here
|
||||
...
|
||||
|
||||
Fix the problem by substituting __packed with __attribute__((packed)) in
|
||||
the header_install.pl script.

Subject: MIPS: Add crash and kdump support
|
||||
|
||||
From: http://patchwork.linux-mips.org/patch/1025/
|
||||
|
||||
Hello folks,
|
||||
|
||||
Please find here MIPS crash and kdump patches.
|
||||
This is patch set of 3 patches:
|
||||
1. generic MIPS changes (kernel);
|
||||
2. MIPS Cavium Octeon board kexec/kdump code (kernel);
|
||||
3. Kexec user space MIPS changes.
|
||||
|
||||
Patches were tested on the latest linux-mips@ git kernel and the latest
|
||||
kexec-tools git on Cavium Octeon 50xx board.
|
||||
|
||||
I also made the same code working on RMI XLR/XLS boards for both
|
||||
mips32 and mips64 kernels.
|
||||
|
||||
Best regards,
|
||||
Maxim Uvarov.
|
||||
|
||||
------
|
||||
[ Zhangjin: Several trivial building failure has been fixed.
|
||||
|
||||
Note: the 2nd patch can not be cleanly applied, but may be a good
|
||||
reference for the other board development:
|
||||
|
||||
+ MIPS Cavium Octeon board kexec,kdump support
|
||||
http://patchwork.linux-mips.org/patch/1026/
|
||||
|
||||
And the 3rd patch has already been merged into the mainline kexec-tools:
|
||||
|
||||
+ some kexec MIPS improvements
|
||||
http://patchwork.linux-mips.org/patch/1027/
|
||||
|
||||
kexec-tools is available here:
|
||||
|
||||
+ http://horms.net/projects/kexec/
|
||||
git://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git

From: Wu Zhangjin <wuzhangjin@gmail.com>
|

Date: Tue, 11 Jan 2011 18:42:08 +0000
|
||||
Subject: MIPS: Kexec: Enhance the support
|
||||
|
||||
Changes:
|
||||
o Print more information in machine_kexec() for debugging
|
||||
E.g. with this information, the kexec_start_address has been found
|
||||
it was wrong with 64bit kernel / o32 kexec-tools. Which must be
|
||||
fixed later.
|
||||
o Link relocate_kernel.S to a section for future extension
|
||||
This allows more functions can be added for the kexec relocation
|
||||
part even written in C. to add code into that section, you just need
|
||||
to mark your function or data with __kexec or
|
||||
__attribute__((__section__(".__kexec.relocate")))
|
||||
|
||||
TODO:
|
||||
|
||||
1. Make 64bit kernel / o32|n32|64 kexec-tools works
|
||||
|
||||
Fix the user-space kexec-tools, seems the tool only work for 32bit
|
||||
machine. So, we need to add 64bit support for it. The address of the
|
||||
entry point(kexec_start_address) is wrong and make the "kexec -e" fail.
|
||||
the real entry point must be read from the new kernel image by the
|
||||
user-space kexec-tools, otherwise, it will not work. The above 64bit
|
||||
support tested is 64bit kernel with o32 user-space kexec-tools. The root
|
||||
cause may be the different definition of virt_to_phys() and
|
||||
phys_to_virt() in the kexec-tools and kernel space for 64bit system /
|
||||
o32 kernel.
|
||||
|
||||
Ref: http://www.linux-mips.org/archives/linux-mips/2009-08/msg00149.html
|
||||
|
||||
2. Pass the arguments from kexec-tools to the new kernel image
|
||||
|
||||
Please refer to: "MIPS: Loongson: Kexec: Pass parameters to new kernel"

Subject: MIPS: Kexec: Init the arguments for the new kernel image
|
||||
|
||||
Whenever the kexec-tools pass the command lines to the new kernel image,
|
||||
init the arguments as the ones for the 1st kernel image. This fixed the
|
||||
booting failure of Kexec on YeeLoong.

Subject: MIPS: Get kernel parameters from kexec-tools
|
||||
|
||||
Before, we simply use the command lines from the original bootloader,
|
||||
but it is not convenient. Now, we accept the kernel parameters from the
|
||||
--command-line or --append option of the kexec-tools. But If not
|
||||
--command-line or --apend option indicated, will fall back to use the
|
||||
ones from the original bootloader.

This patch allows the user to specify desired packet types (outgoing,
|
||||
broadcast, unicast, etc.) on packet sockets via setsockopt.
|
||||
This can reduce the load in situations where only a limited number
|

of packet types are necessary
