  [IMPACT]
   * kexec-tools in Xenial (16.04) currently does not support ARM64
     architecture.
   * Backport support for ARM64 arch from upstream

     one patch that impacts purgatory and common device tree routines.

  [TEST CASE]
   * I built kexec-tools for ARM64 and tested it on HW using the following

Note that the yakkety SRU for this is still in unapproved, so it can't

[Kernel-packages] [Bug 1659618] Re: Enable ARM64 support in kexec-tools

[Brian Murray]

Oh, no it's 1:2.0.10-1ubuntu2.1 that failed to build from source, but
1:2.0.10-1ubuntu2.2 is really in -proposed. This was accepted into
-proposed without adding a comment to the bug which caused my confusion.
Regardless the bug will need to be reverified for 16.04 with the new
version of the package in -proposed.

Chris's comment is also true for Xenial - the armhf version of the
package failed to build.

[Kernel-packages] [Bug 1659618] Re: Enable ARM64 support in kexec-tools

[Chris Halse Rogers]

While this has passed testing on arm64, it introduces a FTBFS regression
in the armhf package on Yakkety: https://launchpad.net/ubuntu/+source
/kexec-tools/1:2.0.10-2ubuntu1.1/+build/12076905

Please resolve this build error and upload a new package.

Bug description:
  [IMPACT]
   * kexec-tools in Xenial (16.04) currently does not support ARM64
     architecture.
   * Backport support for ARM64 arch from upstream
     https://github.com/horms/kexec-tools
   * Majority of the patches are contained in kexec/arch/arm64/ except for
     one patch that impacts purgatory and common device tree routines.

  [TEST CASE]
   * I built kexec-tools for ARM64 and tested it on HW using the following
     testcase:
     $ sudo kexec -l /boot/vmlinuz--generic
   --initrd=/boot/initrd.img--generic
   --command-line="root=UUID= ro vt.handoff=7"
     $ sudo kexec -e
   * I was able to kexec the new kernel successfully.

[Kernel-packages] [Bug 1659618] Re: Enable ARM64 support in kexec-tools

[Brian Murray]

Hello Manoj, or anyone else affected,

Accepted kexec-tools into yakkety-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/kexec-
tools/1:2.0.10-2ubuntu1.1 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

[Kernel-packages] [Bug 1659618] Re: Enable ARM64 support in kexec-tools

[Manoj Iyer]

The attached patch has the complete set of patches needed for kexec support on 
ARM64. 
* Enable ARM64 support in kexec-tools (LP: #1659618)
* Enable support for compressed kernels on ARM64 (LP: #1661363)
* kexec: Increase the upper limit for RAM segments (LP: #1663400)

This patch applies cleanly on Yakkety kexec-tools:
https://pastebin.ubuntu.com/23968404/

Testing for lp 1663400 is posted to the SRU request description. Testing
results for arm64 support yielded the same results as previously.

[Kernel-packages] [Bug 1659618] Re: Enable ARM64 support in kexec-tools

[Manoj Iyer]

Please note that the previous debdiff patch I attached introduced some
spurious changes by accident. Here is a cleaner version of the debdiff
patch for Yakkety. I applied this patch to Yakkety kexec-tools and I was
able to build and test.

Please consider this patch for SRU to kexec-tools in yakkety.

[Kernel-packages] [Bug 1659618] Re: Enable ARM64 support in kexec-tools

[Launchpad Bug Tracker]

This bug was fixed in the package kexec-tools - 1:2.0.14-1ubuntu1

---
kexec-tools (1:2.0.14-1ubuntu1) zesty; urgency=medium

  * Merge from Debian unstable.  Remaining changes:
- Default to not kexecing a kernel on boot in the automatically
  generated conffile
- Don't call db_stop from the postinst.
- Adjust INITCONFFILE to vmlinux if used
- Use format-security.patch instead of const_string_warning.patch
- Add maintainer script helper to handle removal of conffile
  /etc/default/grub.d/kexec-tools.cfg has been removed.
  Handle it properly
- Add Breaks: statement toward kdump-tools
   Starting with kdump-tools 1:1.5.9-6, this package takes
   over the addition of crashkernel= parameter which has
   been removed from kexec-tools.
   Make sure that it is upgraded accordingly.
  * Debian merge adds arm64 support (LP: #1659618).

[Kernel-packages] [Bug 1659618] Re: Enable ARM64 support in kexec-tools

[dann frazier]

Thanks Manoj! A few comments on your prepared package.

- We need to fix in zesty and yakkety as well as xenial
- Version for xenial should be 1:2.0.10-1ubuntu2.1
- Is arm64_build.patch needed? I know we had to add it to Debian for compat w/ 
sid's toolchain, but I'm not sure we need it for Ubuntu or xenial (though it 
shouldn't hurt anything).
- There appears to be unncecessary changes to the other debian/patches files - 
like they were all regenerated. Can you avoid that to cleanup the debdiff for 
sru-team?

Other than that - looks good. Backport appears clean/straightforward.

  Enable ARM64 support in kexec-tools

Bug description:
  [IMPACT]
   * kexec-tools in Xenial (16.04) currently does not support ARM64
     architecture.
   * Backport support for ARM64 arch from upstream
     https://github.com/horms/kexec-tools
   * Majority of the patches are contained in kexec/arch/arm64/ except for
     one patch that impacts purgatory and common device tree routines.

  [TEST CASE]
   * I built kexec-tools for ARM64 and tested it on HW using the following
     testcase:
     $ sudo kexec -l /boot/vmlinuz--generic
   --initrd=/boot/initrd.img--generic
   --command-line="root=UUID= ro vt.handoff=7"
     $ sudo kexec -e
   * I was able to kexec the new kernel successfully.
   * [ 6702.357899] kexec_core: Starting new kernel
     [0.00] Booting Linux on physical CPU 0x200
     [0.00] Linux version -generic (buildd@bos01-arm64-008)
     (gcc version 5.4.0 20160609 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.4) )
     [0.00] Boot CPU: AArch64 Processor [510f8000]

  [REGRESSION POTENTIAL]
   * Since patches are confined to arm[64] there is a low overall risk of
     regression.
