The mac-io IDE already has it's own sysfs entry
You mean in /sys/bus/macio/drivers/ide-pmac ? The main reason is that I could not find how to add my sysfs in this directory since it is not created in the ide-pmac.c file (still a lot to learn :)). So I convinced myself that a platform device was not so irrelevant. Just give me an hint or an example and I'll change that. Other thing strange to me is that I have to use the saved command line to know if there is a boot time argument. According to the comments around MODULE_PARM, a module parameter should be enough. I tried that, but the boot parameter never had any influence on the parameter. Thanks for your remark. -- Cedric Pradalier
