1886 This is a kernel model which is known a VSMP but lately has been
1887 marketesed into SMVP.
1888 Virtual SMP uses the processor's VPEs to implement virtual
1889 processors. In currently available configuration of the 34K processor
1890 this allows for a dual processor. Both processors will share the same
1891 primary caches; each will obtain the half of the TLB for it's own
1892 exclusive use. For a layman this model can be described as similar to
1893 what Intel calls Hyperthreading.

1912 is presenting the available TC's of the core as processors to Linux.
1913 On currently available 34K processors this means a Linux system will
1914 see up to 5 processors. The implementation of the SMTC kernel differs
1915 significantly from VSMP and cannot efficiently coexist in the same
1916 kernel binary so the choice between VSMP and SMTC is a compile time
1917 decision.

2313 kexec is a system call that implements the ability to shutdown your
2314 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2315 but it is independent of the system firmware. And like a reboot
ea6e942b
AN
2316 you can start any kernel with it, not just Linux.
2317
01dd2fbf 2318 The name comes from the similarity to the exec system call.

2320 It is an ongoing process to be certain the hardware in a machine
2321 is properly shutdown, so do not be surprised if this code does not
2322 initially work for you. It may help to enable device hotplugging
2323 support. As of this writing the exact hardware interface is
2324 strongly in flux, so no good recommendation can be made.

2327 bool "Kernel crash dumps"
2328 help
2329 Generate crash dump after being started by kexec.
2330 This should be normally only set in special crash dump kernels
2331 which are loaded in the main kernel with kexec-tools into
2332 a specially reserved region and then later executed after
2333 a crash by kdump/kexec. The crash dump kernel must be compiled
2334 to a memory address not used by the main kernel or firmware using
2335 PHYSICAL_START.
2336
2337config PHYSICAL_START
2338 hex "Physical address where the kernel is loaded"
2339 default "0xffffffff84000000" if 64BIT
2340 default "0x84000000" if 32BIT
2341 depends on CRASH_DUMP
2342 help
2343 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2344 If you plan to use kernel for capturing the crash dump change
2345 this value to start of the reserved region (the "X" value as
2346 specified in the "crashkernel=YM@XM" command line boot parameter
2347 passed to the panic-ed kernel).

2352 default y
2353 help
2354 This kernel feature is useful for number crunching applications
2355 that may need to compute untrusted bytecode during their
2356 execution. By using pipes or other transports made available to
2357 the process as file descriptors supporting the read/write
2358 syscalls, it's possible to isolate those applications in
2359 their own address space using seccomp. Once seccomp is
2360 enabled via /proc/<pid>/seccomp, it cannot be disabled
2361 and the task is only allowed to execute a few safe syscalls
2362 defined by each seccomp mode.
2363
2364 If unsure, say Y. Only embedded should say N here.

2426 The Extended Industry Standard Architecture (EISA) bus was
2427 developed as an open alternative to the IBM MicroChannel bus.
2428
2429 The EISA bus provided some of the features of the IBM MicroChannel
2430 bus while maintaining backward compatibility with cards made for
2431 the older ISA bus. The EISA bus saw limited use between 1988 and
2432 1995 when it was made obsolete by the PCI bus.
