1890 This is a kernel model which is known a VSMP but lately has been
1891 marketesed into SMVP.
1892 Virtual SMP uses the processor's VPEs to implement virtual
1893 processors. In currently available configuration of the 34K processor
1894 this allows for a dual processor. Both processors will share the same
1895 primary caches; each will obtain the half of the TLB for it's own
1896 exclusive use. For a layman this model can be described as similar to
1897 what Intel calls Hyperthreading.

1916 is presenting the available TC's of the core as processors to Linux.
1917 On currently available 34K processors this means a Linux system will
1918 see up to 5 processors. The implementation of the SMTC kernel differs
1919 significantly from VSMP and cannot efficiently coexist in the same
1920 kernel binary so the choice between VSMP and SMTC is a compile time
1921 decision.

2316 help
2317 kexec is a system call that implements the ability to shutdown your
2318 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2319 but it is independent of the system firmware. And like a reboot
ea6e942b

2320 you can start any kernel with it, not just Linux.
2321
01dd2fbf 2322 The name comes from the similarity to the exec system call.

2324 It is an ongoing process to be certain the hardware in a machine
2325 is properly shutdown, so do not be surprised if this code does not
2326 initially work for you. It may help to enable device hotplugging
2327 support. As of this writing the exact hardware interface is
2328 strongly in flux, so no good recommendation can be made.

2332 help
2333 Generate crash dump after being started by kexec.
2334 This should be normally only set in special crash dump kernels
2335 which are loaded in the main kernel with kexec-tools into
2336 a specially reserved region and then later executed after
2337 a crash by kdump/kexec. The crash dump kernel must be compiled
2338 to a memory address not used by the main kernel or firmware using
2339 PHYSICAL_START.

2347 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2348 If you plan to use kernel for capturing the crash dump change
2349 this value to start of the reserved region (the "X" value as
2350 specified in the "crashkernel=YM@XM" command line boot parameter
2351 passed to the panic-ed kernel).

2357 help
2358 This kernel feature is useful for number crunching applications
2359 that may need to compute untrusted bytecode during their
2360 execution. By using pipes or other transports made available to
2361 the process as file descriptors supporting the read/write
2362 syscalls, it's possible to isolate those applications in
2363 their own address space using seccomp. Once seccomp is
2364 enabled via /proc/<pid>/seccomp, it cannot be disabled
2365 and the task is only allowed to execute a few safe syscalls
2366 defined by each seccomp mode.
2367
2368 If unsure, say Y. Only embedded should say N here.

2430 The Extended Industry Standard Architecture (EISA) bus was
2431 developed as an open alternative to the IBM MicroChannel bus.

2433 The EISA bus provided some of the features of the IBM MicroChannel
2434 bus while maintaining backward compatibility with cards made for
2435 the older ISA bus. The EISA bus saw limited use between 1988 and
2436 1995 when it was made obsolete by the PCI bus.
