1871 This is a kernel model which is known a VSMP but lately has been
1872 marketesed into SMVP.
1873 Virtual SMP uses the processor's VPEs to implement virtual
1874 processors. In currently available configuration of the 34K processor
1875 this allows for a dual processor. Both processors will share the same
1876 primary caches; each will obtain the half of the TLB for it's own
1877 exclusive use. For a layman this model can be described as similar to
1878 what Intel calls Hyperthreading.

1897 is presenting the available TC's of the core as processors to Linux.
1898 On currently available 34K processors this means a Linux system will
1899 see up to 5 processors. The implementation of the SMTC kernel differs
1900 significantly from VSMP and cannot efficiently coexist in the same
1901 kernel binary so the choice between VSMP and SMTC is a compile time
1902 decision.

2297 help
2298 kexec is a system call that implements the ability to shutdown your
2299 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2300 but it is independent of the system firmware. And like a reboot
ea6e942b
AN
2301 you can start any kernel with it, not just Linux.
2302
01dd2fbf 2303 The name comes from the similarity to the exec system call.

2304
2305 It is an ongoing process to be certain the hardware in a machine
2306 is properly shutdown, so do not be surprised if this code does not
2307 initially work for you. It may help to enable device hotplugging
2308 support. As of this writing the exact hardware interface is
2309 strongly in flux, so no good recommendation can be made.

2311config CRASH_DUMP
2312 bool "Kernel crash dumps"
2313 help
2314 Generate crash dump after being started by kexec.
2315 This should be normally only set in special crash dump kernels
2316 which are loaded in the main kernel with kexec-tools into
2317 a specially reserved region and then later executed after
2318 a crash by kdump/kexec. The crash dump kernel must be compiled
2319 to a memory address not used by the main kernel or firmware using
2320 PHYSICAL_START.
2321
2322config PHYSICAL_START
2323 hex "Physical address where the kernel is loaded"
2324 default "0xffffffff84000000" if 64BIT
2325 default "0x84000000" if 32BIT
2326 depends on CRASH_DUMP
2327 help
2328 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2329 If you plan to use kernel for capturing the crash dump change
2330 this value to start of the reserved region (the "X" value as
2331 specified in the "crashkernel=YM@XM" command line boot parameter
2332 passed to the panic-ed kernel).

2337 default y
2338 help
2339 This kernel feature is useful for number crunching applications
2340 that may need to compute untrusted bytecode during their
2341 execution. By using pipes or other transports made available to
2342 the process as file descriptors supporting the read/write
2343 syscalls, it's possible to isolate those applications in
2344 their own address space using seccomp. Once seccomp is
2345 enabled via /proc/<pid>/seccomp, it cannot be disabled
2346 and the task is only allowed to execute a few safe syscalls
2347 defined by each seccomp mode.
2348
2349 If unsure, say Y. Only embedded should say N here.

2351config CC_STACKPROTECTOR
2352 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
2353 help
2354 This option turns on the -fstack-protector GCC feature. This
2355 feature puts, at the beginning of functions, a canary value on
2356 the stack just before the return address, and validates
2357 the value just before actually returning. Stack based buffer
2358 overflows (that need to overwrite this return address) now also
2359 overwrite the canary, which gets detected and the attack is then
2360 neutralized via a kernel panic.
2361
2362 This feature requires gcc version 4.2 or above.

2423 The Extended Industry Standard Architecture (EISA) bus was
2424 developed as an open alternative to the IBM MicroChannel bus.
2425
2426 The EISA bus provided some of the features of the IBM MicroChannel
2427 bus while maintaining backward compatibility with cards made for
2428 the older ISA bus. The EISA bus saw limited use between 1988 and
2429 1995 when it was made obsolete by the PCI bus.
