1906 This is a kernel model which is known a VSMP but lately has been
1907 marketesed into SMVP.
1908 Virtual SMP uses the processor's VPEs to implement virtual
1909 processors. In currently available configuration of the 34K processor
1910 this allows for a dual processor. Both processors will share the same
1911 primary caches; each will obtain the half of the TLB for it's own
1912 exclusive use. For a layman this model can be described as similar to
1913 what Intel calls Hyperthreading.

1932 is presenting the available TC's of the core as processors to Linux.
1933 On currently available 34K processors this means a Linux system will
1934 see up to 5 processors. The implementation of the SMTC kernel differs
1935 significantly from VSMP and cannot efficiently coexist in the same
1936 kernel binary so the choice between VSMP and SMTC is a compile time
1937 decision.

2324 kexec is a system call that implements the ability to shutdown your
2325 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2326 but it is independent of the system firmware. And like a reboot
ea6e942b
AN
2327 you can start any kernel with it, not just Linux.
2328
01dd2fbf 2329 The name comes from the similarity to the exec system call.

2331 It is an ongoing process to be certain the hardware in a machine
2332 is properly shutdown, so do not be surprised if this code does not
2333 initially work for you. It may help to enable device hotplugging
2334 support. As of this writing the exact hardware interface is
2335 strongly in flux, so no good recommendation can be made.

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

2353 help
2354 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2355 If you plan to use kernel for capturing the crash dump change
2356 this value to start of the reserved region (the "X" value as
2357 specified in the "crashkernel=YM@XM" command line boot parameter
2358 passed to the panic-ed kernel).

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

2437 The Extended Industry Standard Architecture (EISA) bus was
2438 developed as an open alternative to the IBM MicroChannel bus.

2440 The EISA bus provided some of the features of the IBM MicroChannel
2441 bus while maintaining backward compatibility with cards made for
2442 the older ISA bus. The EISA bus saw limited use between 1988 and
2443 1995 when it was made obsolete by the PCI bus.
