1475 require workarounds. Without workarounds the system may hang
1476 unexpectedly. For more information please refer to the gas
1477 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1478
1479 Loongson 2F03 and later have fixed these issues and no workarounds
1480 are needed. The workarounds have no significant side effect on them
1481 but may decrease the performance of the system so this option should
1482 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1483 systems.

1826 Instead of using the CPU to zero and copy pages, use a Data Mover
1827 channel. These DMA channels are otherwise unused by the standard
1828 SiByte Linux port. Seems to give a small performance benefit.

1868 This is a kernel model which is known a VSMP but lately has been
1869 marketesed into SMVP.
1870 Virtual SMP uses the processor's VPEs to implement virtual
1871 processors. In currently available configuration of the 34K processor
1872 this allows for a dual processor. Both processors will share the same
1873 primary caches; each will obtain the half of the TLB for it's own
1874 exclusive use. For a layman this model can be described as similar to
1875 what Intel calls Hyperthreading.

1894 is presenting the available TC's of the core as processors to Linux.
1895 On currently available 34K processors this means a Linux system will
1896 see up to 5 processors. The implementation of the SMTC kernel differs
1897 significantly from VSMP and cannot efficiently coexist in the same
1898 kernel binary so the choice between VSMP and SMTC is a compile time
1899 decision.

2300config CRASH_DUMP
2301 bool "Kernel crash dumps"
2302 help
2303 Generate crash dump after being started by kexec.
2304 This should be normally only set in special crash dump kernels
2305 which are loaded in the main kernel with kexec-tools into
2306 a specially reserved region and then later executed after
2307 a crash by kdump/kexec. The crash dump kernel must be compiled
2308 to a memory address not used by the main kernel or firmware using
2309 PHYSICAL_START.
2310
2311config PHYSICAL_START
2312 hex "Physical address where the kernel is loaded"
2313 default "0xffffffff84000000" if 64BIT
2314 default "0x84000000" if 32BIT
2315 depends on CRASH_DUMP
2316 help
2317 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2318 If you plan to use kernel for capturing the crash dump change
2319 this value to start of the reserved region (the "X" value as
2320 specified in the "crashkernel=YM@XM" command line boot parameter
2321 passed to the panic-ed kernel).

2326 default y
2327 help
2328 This kernel feature is useful for number crunching applications
2329 that may need to compute untrusted bytecode during their
2330 execution. By using pipes or other transports made available to
2331 the process as file descriptors supporting the read/write
2332 syscalls, it's possible to isolate those applications in
2333 their own address space using seccomp. Once seccomp is
2334 enabled via /proc/<pid>/seccomp, it cannot be disabled
2335 and the task is only allowed to execute a few safe syscalls
2336 defined by each seccomp mode.
2337
2338 If unsure, say Y. Only embedded should say N here.

2340config CC_STACKPROTECTOR
2341 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
2342 help
2343 This option turns on the -fstack-protector GCC feature. This
2344 feature puts, at the beginning of functions, a canary value on
2345 the stack just before the return address, and validates
2346 the value just before actually returning. Stack based buffer
2347 overflows (that need to overwrite this return address) now also
2348 overwrite the canary, which gets detected and the attack is then
2349 neutralized via a kernel panic.
2350
2351 This feature requires gcc version 4.2 or above.

2412 The Extended Industry Standard Architecture (EISA) bus was
2413 developed as an open alternative to the IBM MicroChannel bus.
2414
2415 The EISA bus provided some of the features of the IBM MicroChannel
2416 bus while maintaining backward compatibility with cards made for
2417 the older ISA bus. The EISA bus saw limited use between 1988 and
2418 1995 when it was made obsolete by the PCI bus.
