1905 This is a kernel model which is known a VSMP but lately has been
1906 marketesed into SMVP.
1907 Virtual SMP uses the processor's VPEs to implement virtual
1908 processors. In currently available configuration of the 34K processor
1909 this allows for a dual processor. Both processors will share the same
1910 primary caches; each will obtain the half of the TLB for it's own
1911 exclusive use. For a layman this model can be described as similar to
1912 what Intel calls Hyperthreading.

1931 is presenting the available TC's of the core as processors to Linux.
1932 On currently available 34K processors this means a Linux system will
1933 see up to 5 processors. The implementation of the SMTC kernel differs
1934 significantly from VSMP and cannot efficiently coexist in the same
1935 kernel binary so the choice between VSMP and SMTC is a compile time
1936 decision.

2322 help
2323 kexec is a system call that implements the ability to shutdown your
2324 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2325 but it is independent of the system firmware. And like a reboot
ea6e942b

2326 you can start any kernel with it, not just Linux.
2327
01dd2fbf 2328 The name comes from the similarity to the exec system call.

2330 It is an ongoing process to be certain the hardware in a machine
2331 is properly shutdown, so do not be surprised if this code does not
2332 initially work for you. It may help to enable device hotplugging
2333 support. As of this writing the exact hardware interface is
2334 strongly in flux, so no good recommendation can be made.

2337 bool "Kernel crash dumps"
2338 help
2339 Generate crash dump after being started by kexec.
2340 This should be normally only set in special crash dump kernels
2341 which are loaded in the main kernel with kexec-tools into
2342 a specially reserved region and then later executed after
2343 a crash by kdump/kexec. The crash dump kernel must be compiled
2344 to a memory address not used by the main kernel or firmware using
2345 PHYSICAL_START.
2346
2347config PHYSICAL_START
2348 hex "Physical address where the kernel is loaded"
2349 default "0xffffffff84000000" if 64BIT

2351 depends on CRASH_DUMP
2352 help
2353 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2354 If you plan to use kernel for capturing the crash dump change
2355 this value to start of the reserved region (the "X" value as
2356 specified in the "crashkernel=YM@XM" command line boot parameter
2357 passed to the panic-ed kernel).

2363 help
2364 This kernel feature is useful for number crunching applications
2365 that may need to compute untrusted bytecode during their
2366 execution. By using pipes or other transports made available to
2367 the process as file descriptors supporting the read/write
2368 syscalls, it's possible to isolate those applications in
2369 their own address space using seccomp. Once seccomp is
2370 enabled via /proc/<pid>/seccomp, it cannot be disabled
2371 and the task is only allowed to execute a few safe syscalls
2372 defined by each seccomp mode.
2373
2374 If unsure, say Y. Only embedded should say N here.

2436 The Extended Industry Standard Architecture (EISA) bus was
2437 developed as an open alternative to the IBM MicroChannel bus.

2439 The EISA bus provided some of the features of the IBM MicroChannel
2440 bus while maintaining backward compatibility with cards made for
2441 the older ISA bus. The EISA bus saw limited use between 1988 and
2442 1995 when it was made obsolete by the PCI bus.
