How to disable OVERRIDES temperally

How to disable OVERRIDES temperally

Hi all,

I want to load kernel module ci_hdrc_imx at boot time and add a conf file
in /etc/modprobe.d. I find it can be done by add
module_conf_ci_hdrc_imx = "my configure"

But the suffix "imx" is in OVERRIDES, so I get
module_conf_ci_hdrc = "my configure"

How to disable the OVERRIDES temperally here? Or may be there is another
way?

Thanks,
Qiang

OVERRIDES_remove = "imx" in recipe might help
another case where we should rethink OVERRIDE syntax

This might work (untested):

MY_HDRC_MODULE_NAME = "conf_ci_hdrc"
module_${MY_HDRC_MODULE_NAME} = "my configure"

This removes imx in whole recipe. I want a temporary way in case other
parts need this override.

Test this, same wrong result.

This is an annoying situation, no question about that - it's an unfortunate 
consequence of our long-ago decision to use _ as the override separator. 
Whether or not we can change that in future is up for debate.

In any case though the workaround is probably fairly simple in this case - all 
that the code in kernel_module_split.bbclass that reads this does is to write 
a file to ${D}/etc/modprobe.d/<modulename>.conf - you could just create that 
yourself instead during do_install, then you don't need to set 
module_conf_ci_hdrc_imx.

FWIW. I just tested and in master this should work just fine without any 
workaround (I think the datastore finalisation rework that was done recently 
probably fixed it.) I wouldn't really recommend running master in production, 
but at least this should work better in the next release.

Cheers,
Paul
