97 default "console=ttyUL0,115200"
99 On some architectures there is currently no way for the boot loader
100 to pass arguments to the kernel. For these architectures, you should
101 supply some command-line options at build time by entering them
105 bool "Force default kernel command string"
106 depends on CMDLINE_BOOL
109 Set this to have arguments from the default kernel command string
110 override those passed by the boot loader.
113 bool "Enable seccomp to safely compute untrusted bytecode"
117 This kernel feature is useful for number crunching applications
118 that may need to compute untrusted bytecode during their
119 execution. By using pipes or other transports made available to
120 the process as file descriptors supporting the read/write
121 syscalls, it's possible to isolate those applications in
122 their own address space using seccomp. Once seccomp is
123 enabled via /proc/<pid>/seccomp, it cannot be disabled
124 and the task is only allowed to execute a few safe syscalls
125 defined by each seccomp mode.
127 If unsure, say Y. Only embedded should say N here.

136 This option will enable prompting for a variety of advanced kernel
137 configuration options. These options can cause the kernel to not
138 work if they are set incorrectly, but can be used to optimize certain
139 aspects of kernel memory management.

176 access directly, without having to set up a kernel virtual mapping.

193 layout of the system.

219 depends on ADVANCED_OPTIONS && !MMU
221 Select the kernel logical page size. Increasing the page size
222 will reduce software overhead at each page boundary, allow
223 hardware prefetch mechanisms to be more effective, and allow
224 larger dma transfers increasing IO efficiency and reducing
225 overhead. However the utilization of memory will increase.
226 For example, each cached file will using a multiple of the
227 page size to hold its contents and the difference between the
228 end of file and the end of page is wasted.
230 If unsure, choose 4K_PAGES.
