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

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

178 This option allows you to set the maximum amount of memory which
179 will be used as "low memory", that is, memory which the kernel can
180 access directly, without having to set up a kernel virtual mapping.

205 This option allows you to set the kernel virtual address at which
206 the kernel will map low memory (the kernel image will be linked at
207 this address). This can be useful in optimizing the virtual memory
208 layout of the system.

223 virtual memory layout of the system.

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