Reserve a 1MiB region of memory to record kmsg dumps and console state
into 16kiB ring-buffer slots. The sizing allows for up to 32 dumps to be
captured and read out.

This is conserative. We've got plenty of space, how about we make it bigger?
$ git grep console-size *.dts* | grep -Po "0x([0-9]+)" | xargs printf

The median is 128KB, which sounds reasonable.

Do we want to add ftrace too?
Should we also add max-reason = KMSG_DUMP_EMERG?
Logging reboots and shutdowns is informative (you know if a reboot was
intentional or due to a crash that wasn't recorded) and allows for
testing.

Well, maybe? Why should we basing it on what everyone else has done rather than
what we need? We're compressing the data before it's written to the pstore
ring. Uncompressed, 16k is in the order of 200 lines of text. With the default
DEFLATE compression we can fit 3-4x more:
root@rain15bmc:~# uptime
14:44:20 up 14:44, load average: 0.01, 0.01, 0.01
root@rain15bmc:~# dmesg | wc -l
640
root@rain15bmc:~# dmesg >/tmp/dmesg
root@rain15bmc:~# stat -c "%s" /tmp/dmesg
44032
root@rain15bmc:~# gzip /tmp/dmesg
root@rain15bmc:~# stat -c "%s" /tmp/dmesg.gz
11059
I think 16k is more than enough for now?

I figured getting an oops/panic stack dump might be enough for the moment.

Yeah, that's a good idea.

How big is the dmesg after we are booted? How big is the default
kernel buffer for 2 cpus (the kernel config has a base size, but
also a dynamic size with a base + n * cpu min at boot).
Having the console space larger than printk buffer will not help.
We could config the buffer up if we are not capturing enough of a
boot and some runtime.

This probably affects the effective compression, assuming
each block is a seperate compression input.

The admin guide lists KMSG_DUMP_OOPS and KMSG_DUMP_PANIC ?
https://www.kernel.org/doc/html/latest/admin-guide/ramoops.html
We could have something monitoring for OOPS , copying to a log and
then unlinking the pstore after committed.

That should be exposed from audit logging?
but yes.

systemd-pstore already does this for us, no further configuration required.

Do we have something that creates service records for these messages?
I was hoping for something like a PEL for the bmc software.
Not as part of this kernel series though.
