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

2331 help
2332 kexec is a system call that implements the ability to shutdown your
2333 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2334 but it is independent of the system firmware. And like a reboot
ea6e942b

2335 you can start any kernel with it, not just Linux.

2339 It is an ongoing process to be certain the hardware in a machine
2340 is properly shutdown, so do not be surprised if this code does not
2341 initially work for you. It may help to enable device hotplugging
2342 support. As of this writing the exact hardware interface is
2343 strongly in flux, so no good recommendation can be made.

2348 Generate crash dump after being started by kexec.
2349 This should be normally only set in special crash dump kernels
2350 which are loaded in the main kernel with kexec-tools into
2351 a specially reserved region and then later executed after
2352 a crash by kdump/kexec. The crash dump kernel must be compiled
2353 to a memory address not used by the main kernel or firmware using
2354 PHYSICAL_START.

2362 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.

2364 this value to start of the reserved region (the "X" value as

2373 This kernel feature is useful for number crunching applications
2374 that may need to compute untrusted bytecode during their
2375 execution. By using pipes or other transports made available to
2376 the process as file descriptors supporting the read/write
2377 syscalls, it's possible to isolate those applications in
2378 their own address space using seccomp. Once seccomp is
2379 enabled via /proc/<pid>/seccomp, it cannot be disabled
2380 and the task is only allowed to execute a few safe syscalls
2381 defined by each seccomp mode.

2448 The EISA bus provided some of the features of the IBM MicroChannel
2449 bus while maintaining backward compatibility with cards made for
2450 the older ISA bus. The EISA bus saw limited use between 1988 and
2451 1995 when it was made obsolete by the PCI bus.
