Bug Description
[SRU justification]
This represent a hardware enablement SRU : Firmware assisted dumps (fadump) are not possible on LTS.
[Impact]
The fadump mechanism cannot be used on Power systems running Trusty
[Fix]
Backport fadump functionality from makedumpfile 1.5.8 present in Wily and onward.
[Test Case]
See comment #9 : The proposed SRU has been tested from a PPA on a Power VM.
[Regression]
None expected from a functionality point of view as it is a new feature. Existing code paths are minimally modified.
[Original description of the problem]
---Steps to Reproduce---
1) Using latest daily ISO install 14.04.02 as a Power VM guest.
2) Upgrade the kernel to 3.19 level (3.19.0-18-generic)
3) In order to use Firmware Assisted Dump feature update the kernel command with fadump=on.
4) Reboot.
Post reboot using kdump-config load command fails with following message :
# kdump-config load
Memory for crashkernel is not reserved
Please reserve memory by passing"
Then try to loading kdump kernel
* failed to load kdump kernel
# kdump-config status
current state : Not ready to kdump
#
# cat /proc/cmdline
BOOT_IMAGE=
# cat /sys/kernel/
1
# cat /sys/kernel/
0
#
# dmesg | grep -i Firmware
[ 0.000000] Reserved 5120MB of memory at 97279MB for firmware-assisted dump
[ 0.000000] firmware_features = 0x00000001c45ffc5f
#
# cat /boot/config-
CONFIG_FA_DUMP=y
#
Are there any user space fixes missing which prevents me from configuring firmware assisted dump ?
== Comment: #4 - Hari Krishna Bathini <email address hidden> - 2015-06-12 05:28:24 ==
This patch makes kdump-tools fadump aware so as to switch between
kdump & fadump seemlessly based on the dump method enabled (fadump/kdump).
Thanks
Hari
