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

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

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

202 This option allows you to set the kernel virtual address at which

204 this address). This can be useful in optimizing the virtual memory
205 layout of the system.

230 default MICROBLAZE_4K_PAGES
231 depends on ADVANCED_OPTIONS && !MMU
233 Select the kernel logical page size. Increasing the page size
234 will reduce software overhead at each page boundary, allow
235 hardware prefetch mechanisms to be more effective, and allow
236 larger dma transfers increasing IO efficiency and reducing
237 overhead. However the utilization of memory will increase.
238 For example, each cached file will using a multiple of the
239 page size to hold its contents and the difference between the
240 end of file and the end of page is wasted.
242 If unsure, choose 4K_PAGES.
