Package: kdump-tools
Version: 1:1.5.3-2
Dear Maintainer,
The documentation provided in kdump-tools package states nmi_watchdog should be
set to 1 in kernel command line on x86 and x86_64 architectures.
http://sources.debian.net/src/makedumpfile/1:1.5.9-5/debian/kdump-tools.README.Debian/#L58
Correct me if I'm wrong, but the goal is to call kernel panic when the watchdog
detects the system is stalled, right?
As far as I can understand kernel source code, nmi_watchdog=1 is actually the
default in Debian kernels.
- On jessie (3.16.7-ckt25-2):
http://sources.debian.net/src/linux/3.16.7-ckt25-2/kernel/watchdog.c/#L32
The nmi_watchdog parameter logic is in hardlockup_panic_setup() which does
basically nothing for nmi_watchdog=1.
- On stretch (4.5.3-2):
http://sources.debian.net/src/linux/4.5.3-2/kernel/watchdog.c/#L50
The NMI watchdog is enabled as long as CONFIG_HARDLOCKUP_DETECTOR is set,
and it is set on x86 and x86_64.
The nmi_watchdog=1 seems to be useless for all kernels on this architecture.
For the panic call on NMI watchdog thing, the default value is controlled by
CONFIG_BOOTPARAM_HARDLOCKUP_PANIC. It is not set in debian kernels:
http://sources.debian.net/src/linux/4.5.3-2/debian/config/config/#L5741
Then, the NMI watchdog won't call panic by default.
However, the logic in hardlockup_panic_setup() tells it can be enabled with
nmi_watchdog=panic in kernel command line tough.
If I'm hopefully right in all my guesses, my conclusion is that kdump-tools
documentation should recommend setting nmi_watchdog=panic in kernel command
line on x86 and x86_64.
I'm looking forward to reading from you soon!
Best,
Rémi
