1514 Loongson 2F03 and later have fixed these issues and no workarounds

1839 channel. These DMA channels are otherwise unused by the standard
1840 SiByte Linux port. Seems to give a small performance benefit.

1881 This is a kernel model which is known a VSMP but lately has been
1882 marketesed into SMVP.
1883 Virtual SMP uses the processor's VPEs to implement virtual
1884 processors. In currently available configuration of the 34K processor
1885 this allows for a dual processor. Both processors will share the same
1886 primary caches; each will obtain the half of the TLB for it's own
1887 exclusive use. For a layman this model can be described as similar to
1888 what Intel calls Hyperthreading.

1907 is presenting the available TC's of the core as processors to Linux.
1908 On currently available 34K processors this means a Linux system will
1909 see up to 5 processors. The implementation of the SMTC kernel differs
1910 significantly from VSMP and cannot efficiently coexist in the same
1911 kernel binary so the choice between VSMP and SMTC is a compile time

2312 help
2313 Generate crash dump after being started by kexec.
2314 This should be normally only set in special crash dump kernels
2315 which are loaded in the main kernel with kexec-tools into
2316 a specially reserved region and then later executed after
2317 a crash by kdump/kexec. The crash dump kernel must be compiled
2318 to a memory address not used by the main kernel or firmware using
2319 PHYSICAL_START.
2320
2321config PHYSICAL_START
2322 hex "Physical address where the kernel is loaded"
2323 default "0xffffffff84000000" if 64BIT
2324 default "0x84000000" if 32BIT
2325 depends on CRASH_DUMP
2326 help
2327 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2328 If you plan to use kernel for capturing the crash dump change
2329 this value to start of the reserved region (the "X" value as
2330 specified in the "crashkernel=YM@XM" command line boot parameter
2331 passed to the panic-ed kernel).

2336 default y
2337 help
2338 This kernel feature is useful for number crunching applications
2339 that may need to compute untrusted bytecode during their
2340 execution. By using pipes or other transports made available to
2341 the process as file descriptors supporting the read/write
2342 syscalls, it's possible to isolate those applications in
2343 their own address space using seccomp. Once seccomp is
2344 enabled via /proc/<pid>/seccomp, it cannot be disabled
2345 and the task is only allowed to execute a few safe syscalls
2346 defined by each seccomp mode.
2347
2348 If unsure, say Y. Only embedded should say N here.

2410 The Extended Industry Standard Architecture (EISA) bus was
2411 developed as an open alternative to the IBM MicroChannel bus.
2412
2413 The EISA bus provided some of the features of the IBM MicroChannel
2414 bus while maintaining backward compatibility with cards made for
2415 the older ISA bus. The EISA bus saw limited use between 1988 and
2416 1995 when it was made obsolete by the PCI bus.
2417
2418 Say Y here if you are building a kernel for an EISA-based machine.
