How do I add threadirqs as a default boot parameter for a linux kernel not editing boot configs?

I've been trying to find some docs on how to get the kernel to boot with
the threadirqs by default, and not needing to pass that option manually
at boot time (or editing a boot config).
Or, any boot option for that matter..
Anyone care to shed some light on this? :)

I assume it is done in the kernel source

Hi, here with:
Ubuntu 10.04.2
Grub2
Kernel 2.6.39 with CONFIG_IRQ_FORCED_THREADING=y
i have GRUB_CMDLINE_LINUX="threadirqs" configured in /etc/default/grub file.
Remember to run update-grub if you modify /etc/default/grub file.

Thank you, but this only solves adding the boot parameter for a
particular system install.
I would prefer finding out how to add it to a kernel source,
alternatively, a kernel package source. How can I build the kernel to
have the threadirqs option by default?

Hi, sorry but I don't really know how to do this, I don't know even if it
is possible, I mean, just enable threadirq option using kernel parameters
only.
Maybe some other people can put a light on this for both of us ;-)

Hi Diego,
regarding to my extensive googling some days before this thread was
opened, it's impossible. There's the need to set it as boot option.
Since nobody answered how to do this on this list, it's likely that it's
really impossible.
Regards,
Ralf

You could try adding a built-in kernel command string (Processor type
and features - Built-in kernel command line). Never tried this so not
sure if it works.

That is an option. I found info here
http://cateee.net/lkddb/web-lkddb/CMDLINE.html
So, boot command line arguments could be added to the file
arch/<arch>/Kconfig, under either CONFIG_CMDLINE, or
CONFIG_CMDLINE_OVERRIDE, preferably the former. And they depend on
CONFIG_CMDLINE_BOOL.
