我们接着往下看start_kernel。 调用setup_command_line,将cmdline拷贝2份,放在saved_command_line static_command_line。 下面调用parse_early_param(),如下: 代码语言:javascript 复制 void__initparse_early_options(char*cmdline){parse_args("early options",cmdline,NULL,0,0,0,do_early_param);}/* Arch cod...
auto detected or can be forced by using a kernel command line option such as "mem=256M". (Try "man bootparam" or see the documentation of your boot loader (lilo or loadlin) about how to pass options to the kernel at boot time.) If unsure, say "off". config HIGHMEM...
Also the-r, --reverseflag is used for reversing the kernel module list. kmon --reverse Customizing the colors kmon uses the colors of the terminal as default but the highlighting color could be specified with-c, --coloroption. Alternatively, default text color can be set via-a, --accent...
The value of theroot=option on the kernel command line was not correct. This option is required bydracut, which handles the boot. Example: Raw kernel /vmlinuz-2.6.32-279.14.1.el6.x86_64 ro root= rd_NO_LUKS LANG=en_US.UTF-8 rd_LVM_LV=vg00/lvol2 rd_NO_MD .. ^ + [ Value of...
If the target computer has stopped responding, the target computer is still stopped because of an earlier kernel debugging action, or you used the-bcommand-line option, the debugger breaks into the target computer immediately. Otherwise, the target computer continues running until the debugger orders...

Linux kernel release 3.x <http://kernel.org/> These are the release notes for Linux version 3. Read them carefully, as they tell you what this is all about, explain how to install the kernel, and what to do if something goes wrong. WHAT IS LINUX? Linux is a clone of the operating...
In cases where avoiding freeing such allocations is not possible, you should limit profiling to one range using --launch-count 1, set the disable-host-restore range replay option and optionally use --kill yes to terminate the process after this range. Defining narrow ranges at local scope ...

You will still need the parsing functions to be called by the driver for your particular device. It won't happen automatically. The SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for example. The format for the command line is as follows: ...
