kernel-parameters.txt

if you installed the kernel documentation on 11.3 and every 10.x i
tried, there was a really neat listing of available kernel CLI switches
at /usr/src/linux/Documentation/kernel-parameters.txt

i can’t find it on 11.4, is there another place which that long list of
acpi switches is documented (for the kernel i have installed)???

The file is in the kernel source, which is where you found it earlier. To get it
for 2.6.37, you need to install that package.

you are right! it is in source (and not doc, as i had misremembered)…

thanks!

Anyone that does kernel development gets very used to perusing the information
in the Documentation tree of the kernel sources.

One word of caution - driver developers do not always update that file. To see a
complete list of the parameters that a given driver will accept at load time, do
a ‘grep module_param’ on the sources for that driver. For example, b43 handles
the following options:

drivers/net/wireless/b43/main.c:module_param_named(bad_frames_preempt,
modparam_bad_frames_preempt, int, 0444);
drivers/net/wireless/b43/main.c:module_param_string(fwpostfix,
modparam_fwpostfix, 16, 0444);
drivers/net/wireless/b43/main.c:module_param_named(hwpctl, modparam_hwpctl, int,
0444);
drivers/net/wireless/b43/main.c:module_param_named(nohwcrypt,
modparam_nohwcrypt, int, 0444);
drivers/net/wireless/b43/main.c:module_param_named(hwtkip, modparam_hwtkip, int,
0444);
drivers/net/wireless/b43/main.c:module_param_named(qos, modparam_qos, int, 0444);
drivers/net/wireless/b43/main.c:module_param_named(btcoex, modparam_btcoex, int,
0444);
drivers/net/wireless/b43/main.c:module_param_named(verbose,
b43_modparam_verbose, int, 0644);
drivers/net/wireless/b43/main.c:module_param_named(pio, b43_modparam_pio, int,
0644);
