1831 event driver is always present, so if the platform ends up not
1832 detecting a GIC, it will fall back to the R4K timer for the

1904 This is a kernel model which is known a VSMP but lately has been
1905 marketesed into SMVP.
1906 Virtual SMP uses the processor's VPEs to implement virtual
1907 processors. In currently available configuration of the 34K processor
1908 this allows for a dual processor. Both processors will share the same
1909 primary caches; each will obtain the half of the TLB for it's own
1910 exclusive use. For a layman this model can be described as similar to
1911 what Intel calls Hyperthreading.

1930 is presenting the available TC's of the core as processors to Linux.
1931 On currently available 34K processors this means a Linux system will
1932 see up to 5 processors. The implementation of the SMTC kernel differs
1933 significantly from VSMP and cannot efficiently coexist in the same
1934 kernel binary so the choice between VSMP and SMTC is a compile time
1935 decision.

2330 help
2331 kexec is a system call that implements the ability to shutdown your
2332 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2333 but it is independent of the system firmware. And like a reboot

2334 you can start any kernel with it, not just Linux.

2338 It is an ongoing process to be certain the hardware in a machine
2339 is properly shutdown, so do not be surprised if this code does not
2340 initially work for you. It may help to enable device hotplugging
2341 support. As of this writing the exact hardware interface is
2342 strongly in flux, so no good recommendation can be made.

2347 Generate crash dump after being started by kexec.
2348 This should be normally only set in special crash dump kernels
2349 which are loaded in the main kernel with kexec-tools into
2350 a specially reserved region and then later executed after
2351 a crash by kdump/kexec. The crash dump kernel must be compiled
2352 to a memory address not used by the main kernel or firmware using
2353 PHYSICAL_START.

2361 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.

2363 this value to start of the reserved region (the "X" value as

2372 This kernel feature is useful for number crunching applications
2373 that may need to compute untrusted bytecode during their
2374 execution. By using pipes or other transports made available to
2375 the process as file descriptors supporting the read/write
2376 syscalls, it's possible to isolate those applications in
2377 their own address space using seccomp. Once seccomp is
2378 enabled via /proc/<pid>/seccomp, it cannot be disabled
2379 and the task is only allowed to execute a few safe syscalls
2380 defined by each seccomp mode.

2447 The EISA bus provided some of the features of the IBM MicroChannel
2448 bus while maintaining backward compatibility with cards made for
2449 the older ISA bus. The EISA bus saw limited use between 1988 and
2450 1995 when it was made obsolete by the PCI bus.
