991 This option supports all of the Octeon reference boards from Cavium
992 Networks. It builds a kernel that dynamically determines the Octeon
993 CPU type and supports all known board reference implementations.
994 Some of the supported boards are:
995 EBT3000
996 EBH3000
997 EBH3100
998 Thunder
999 Kodama
1000 Hikari
1001 Say Y here for most Octeon reference boards.

1651 Please make sure to pick the right CPU type. Linux/MIPS is not
1652 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1653 *not* work on R4000 machines and vice versa. However, since most
1654 of the supported machines have an R4000 (or similar) CPU, R4x00
1655 might be a safe bet. If the resulting kernel does not work,
1656 try to recompile with R3000.

1871 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1872 benefit is to increase physical addressing equal to or greater
1873 than 40 bits. Note that this has the side effect of turning on
1874 64-bit addressing which in turn makes the PTEs 64-bit in size.

1890 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1891 require workarounds. Without workarounds the system may hang
1892 unexpectedly. For more information please refer to the gas
1893 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1894
1895 Loongson 2F03 and later have fixed these issues and no workarounds
1896 are needed. The workarounds have no significant side effect on them
1897 but may decrease the performance of the system so this option should
1898 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1899 systems.

Steven J. Hillc080faa2013-10-04 16:23:28 -05002380 This is a kernel model which is known as SMVP. This is supported
2381 on cores with the MT ASE and uses the available VPEs to implement
2382 virtual processors which supports SMP. This is equivalent to the
2383 Intel Hyperthreading feature. For further information go to

3069 Beware that there is very little in terms of protection against
3070 this option being confused by leftover garbage in memory that might
3071 look like a DTB header after a reboot if no actual DTB is appended
3072 to vmlinux.bin. Do not leave this option active in a production kernel
3073 if you don't intend to always append a DTB.
