How to get the list of options of a linux kernel module?
For 开发者_如何学Pythonexample, there is a max_loop
option for the loop
module.
Generally, how can I know what options are supported by a kernel module? Or, where can I find the list, should I dive into the source codes?
Documentation/kernel-parameters.txt
in the kernel documentation will give you many of them, and any in modules can be gleaned from modinfo
.
# modinfo radeon
