1554 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1557 might be a safe bet. If the resulting kernel does not work,

1801 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1802 require workarounds. Without workarounds the system may hang
1803 unexpectedly. For more information please refer to the gas
1804 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1805
1806 Loongson 2F03 and later have fixed these issues and no workarounds
1807 are needed. The workarounds have no significant side effect on them
1808 but may decrease the performance of the system so this option should
1809 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1810 systems.

Steven J. Hillc080faa2013-10-04 16:23:28 -05002263 This is a kernel model which is known as SMVP. This is supported
2264 on cores with the MT ASE and uses the available VPEs to implement
2265 virtual processors which supports SMP. This is equivalent to the
2266 Intel Hyperthreading feature. For further information go to

2954 Beware that there is very little in terms of protection against
2955 this option being confused by leftover garbage in memory that might
2956 look like a DTB header after a reboot if no actual DTB is appended
2957 to vmlinux.bin. Do not leave this option active in a production kernel

3067 developed as an open alternative to the IBM MicroChannel bus.

3069 The EISA bus provided some of the features of the IBM MicroChannel
3070 bus while maintaining backward compatibility with cards made for
3071 the older ISA bus. The EISA bus saw limited use between 1988 and
3072 1995 when it was made obsolete by the PCI bus.
