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

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

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

199 This option allows you to set the kernel virtual address at which
200 the kernel will map low memory (the kernel image will be linked at
201 this address). This can be useful in optimizing the virtual memory
202 layout of the system.

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