1889 This is a kernel model which is known a VSMP but lately has been
1890 marketesed into SMVP.
1891 Virtual SMP uses the processor's VPEs to implement virtual
1892 processors. In currently available configuration of the 34K processor
1893 this allows for a dual processor. Both processors will share the same
1894 primary caches; each will obtain the half of the TLB for it's own
1895 exclusive use. For a layman this model can be described as similar to
1896 what Intel calls Hyperthreading.

1915 is presenting the available TC's of the core as processors to Linux.
1916 On currently available 34K processors this means a Linux system will
1917 see up to 5 processors. The implementation of the SMTC kernel differs
1918 significantly from VSMP and cannot efficiently coexist in the same
1919 kernel binary so the choice between VSMP and SMTC is a compile time
1920 decision.

2315 help
2316 kexec is a system call that implements the ability to shutdown your
2317 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2318 but it is independent of the system firmware. And like a reboot
ea6e942b

2319 you can start any kernel with it, not just Linux.
2320
01dd2fbf 2321 The name comes from the similarity to the exec system call.

2323 It is an ongoing process to be certain the hardware in a machine
2324 is properly shutdown, so do not be surprised if this code does not
2325 initially work for you. It may help to enable device hotplugging
2326 support. As of this writing the exact hardware interface is
2327 strongly in flux, so no good recommendation can be made.

2331 help
2332 Generate crash dump after being started by kexec.
2333 This should be normally only set in special crash dump kernels
2334 which are loaded in the main kernel with kexec-tools into
2335 a specially reserved region and then later executed after
2336 a crash by kdump/kexec. The crash dump kernel must be compiled
2337 to a memory address not used by the main kernel or firmware using
2338 PHYSICAL_START.
2339
2340config PHYSICAL_START
2341 hex "Physical address where the kernel is loaded"

2345 help
2346 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2347 If you plan to use kernel for capturing the crash dump change
2348 this value to start of the reserved region (the "X" value as
2349 specified in the "crashkernel=YM@XM" command line boot parameter
2350 passed to the panic-ed kernel).

2356 help
2357 This kernel feature is useful for number crunching applications
2358 that may need to compute untrusted bytecode during their
2359 execution. By using pipes or other transports made available to
2360 the process as file descriptors supporting the read/write
2361 syscalls, it's possible to isolate those applications in
2362 their own address space using seccomp. Once seccomp is
2363 enabled via /proc/<pid>/seccomp, it cannot be disabled
2364 and the task is only allowed to execute a few safe syscalls
2365 defined by each seccomp mode.
2366
2367 If unsure, say Y. Only embedded should say N here.

2429 The Extended Industry Standard Architecture (EISA) bus was
2430 developed as an open alternative to the IBM MicroChannel bus.

2432 The EISA bus provided some of the features of the IBM MicroChannel
2433 bus while maintaining backward compatibility with cards made for
2434 the older ISA bus. The EISA bus saw limited use between 1988 and
2435 1995 when it was made obsolete by the PCI bus.
