For these architectures, you should supply some command-line options at build time by entering them here. config CMDLINE_FORCE bool "Force default kernel command string" depends on CMDLINE_BOOL default n help Set this to have arguments from the default kernel command string override those passed by the boot loader. |

config SECCOMP bool "Enable seccomp to safely compute untrusted bytecode" depends on PROC_FS default y help This kernel feature is useful for number crunching applications that may need to compute untrusted bytecode during their execution. By using pipes or other transports made available to the process as file descriptors supporting the read/write syscalls, it's possible to isolate those applications in their own address space using seccomp. Once seccomp is enabled via /proc/<pid>/seccomp, it cannot be disabled and the task is only allowed to execute a few safe syscalls defined by each seccomp mode. If unsure, say Y. Only embedded should say N here. |

choice prompt "Page size" default MICROBLAZE_4K_PAGES depends on ADVANCED_OPTIONS && !MMU help Select the kernel logical page size. Increasing the page size will reduce software overhead at each page boundary, allow hardware prefetch mechanisms to be more effective, and allow larger dma transfers increasing IO efficiency and reducing overhead. However the utilization of memory will increase. For example, each cached file will using a multiple of the page size to hold its contents and the difference between the end of file and the end of page is wasted. If unsure, choose 4K_PAGES. config MICROBLAZE_4K_PAGES bool "4k page size" config MICROBLAZE_8K_PAGES bool "8k page size" config MICROBLAZE_16K_PAGES bool "16k page size" config MICROBLAZE_32K_PAGES bool "32k page size" endchoice |
