[PATCH] kdumpctl: Add the command "kdumpctl showmem" to show the reserved memory

[Minfei Huang]

If the grub kernel commandline is set to crashkernel=auto, it will not
expand the crashkernel=auto in the /proc/cmdline. It still says
crashkernel=auto.

Using /sys to determines crashkernel actual size is confusing since
there is no unit of measure.

Add a new command "kdumpctl showmem" to show the reserved memory kindly.

Hi Minfei,

I don't think this is necessary. kdumpctl is used to manage the kdump
kernel load/unload, we don't need to provide another option to show how
much crash memory is reserved. I think /sys/kernel/kexec_xxx is enough.

Thanks

The unit of /sys/kernel/kexec_xxx is B. It does not show kindly to the user.

Maybe you are right, we should not add the duplicate function in the 
kdumpctl script.

I will mark it to the bugzilla that it is necessary to implement this 
command.

Bao,

Agreed that it is not necessary. Just that it makes it easier for some
people. I have a bug open for this. If it makes it easier to find how
much memory is reserved, it does not harm.

OK, I am fine with it. Just worry other requirements also can be added
into kdumpctl to make it a little mess if this is started. Anyway, I
don't object to this strongly.

Ok, I am checking with Jeff Burke and see if he still like to see it. If
he agrees, then we can drop it.

Actually, can we make MEM_RESERVED local.

local mem_reserved.

How about show the value in "kdumpctl status" output?

I think it is better. We can show the reserved memory like following:

[minfei@localhost kexec-tools]$ sudo systemctl stop kdump
[minfei@localhost kexec-tools]$ sudo kdumpctl status
Kdump is not operational

[minfei@localhost kexec-tools]$ sudo systemctl start kdump
[minfei@localhost kexec-tools]$ sudo kdumpctl status
Kdump is operational (Reserved memory 128MB)

I think in this case, we'd better output how much memory we reserved as
well, as the following:

Kdump is not operational (Reserved memory 128M).

Initially I had thought about it. I personally prefer implementing a
separate command instead of overloading "kdump status".  When people
do kdump status, they are more interested in figuring out if kdump
is running or not. (And not necessarily amount of memory reserved).
