1872 This is a kernel model which is known a VSMP but lately has been
1873 marketesed into SMVP.
1874 Virtual SMP uses the processor's VPEs to implement virtual
1875 processors. In currently available configuration of the 34K processor
1876 this allows for a dual processor. Both processors will share the same
1877 primary caches; each will obtain the half of the TLB for it's own
1878 exclusive use. For a layman this model can be described as similar to
1879 what Intel calls Hyperthreading.

1898 is presenting the available TC's of the core as processors to Linux.
1899 On currently available 34K processors this means a Linux system will
1900 see up to 5 processors. The implementation of the SMTC kernel differs
1901 significantly from VSMP and cannot efficiently coexist in the same
1902 kernel binary so the choice between VSMP and SMTC is a compile time
1903 decision.

2298 help
2299 kexec is a system call that implements the ability to shutdown your
2300 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2301 but it is independent of the system firmware. And like a reboot
ea6e942b
AN
2302 you can start any kernel with it, not just Linux.
2303
01dd2fbf 2304 The name comes from the similarity to the exec system call.

2305
2306 It is an ongoing process to be certain the hardware in a machine
2307 is properly shutdown, so do not be surprised if this code does not
2308 initially work for you. It may help to enable device hotplugging
2309 support. As of this writing the exact hardware interface is
2310 strongly in flux, so no good recommendation can be made.

2312config CRASH_DUMP
2313 bool "Kernel crash dumps"
2314 help
2315 Generate crash dump after being started by kexec.
2316 This should be normally only set in special crash dump kernels
2317 which are loaded in the main kernel with kexec-tools into
2318 a specially reserved region and then later executed after
2319 a crash by kdump/kexec. The crash dump kernel must be compiled
2320 to a memory address not used by the main kernel or firmware using
2321 PHYSICAL_START.
2322
2323config PHYSICAL_START
2324 hex "Physical address where the kernel is loaded"
2325 default "0xffffffff84000000" if 64BIT
2326 default "0x84000000" if 32BIT
2327 depends on CRASH_DUMP
2328 help
2329 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2330 If you plan to use kernel for capturing the crash dump change
2331 this value to start of the reserved region (the "X" value as
2332 specified in the "crashkernel=YM@XM" command line boot parameter
2333 passed to the panic-ed kernel).

2338 default y
2339 help
2340 This kernel feature is useful for number crunching applications
2341 that may need to compute untrusted bytecode during their
2342 execution. By using pipes or other transports made available to
2343 the process as file descriptors supporting the read/write
2344 syscalls, it's possible to isolate those applications in
2345 their own address space using seccomp. Once seccomp is
2346 enabled via /proc/<pid>/seccomp, it cannot be disabled
2347 and the task is only allowed to execute a few safe syscalls
2348 defined by each seccomp mode.
2349
2350 If unsure, say Y. Only embedded should say N here.

2352config CC_STACKPROTECTOR
2353 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
2354 help
2355 This option turns on the -fstack-protector GCC feature. This
2356 feature puts, at the beginning of functions, a canary value on
2357 the stack just before the return address, and validates
2358 the value just before actually returning. Stack based buffer
2359 overflows (that need to overwrite this return address) now also
2360 overwrite the canary, which gets detected and the attack is then
2361 neutralized via a kernel panic.
2362
2363 This feature requires gcc version 4.2 or above.

2424 The Extended Industry Standard Architecture (EISA) bus was
2425 developed as an open alternative to the IBM MicroChannel bus.
2426
2427 The EISA bus provided some of the features of the IBM MicroChannel
2428 bus while maintaining backward compatibility with cards made for
2429 the older ISA bus. The EISA bus saw limited use between 1988 and
2430 1995 when it was made obsolete by the PCI bus.
