1301 Please make sure to pick the right CPU type. Linux/MIPS is not
1302 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1303 *not* work on R4000 machines and vice versa. However, since most
1304 of the supported machines have an R4000 (or similar) CPU, R4x00
1305 might be a safe bet. If the resulting kernel does not work,
1306 try to recompile with R3000.

1528 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1529 require workarounds. Without workarounds the system may hang
1530 unexpectedly. For more information please refer to the gas
1531 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1532
1533 Loongson 2F03 and later have fixed these issues and no workarounds
1534 are needed. The workarounds have no significant side effect on them
1535 but may decrease the performance of the system so this option should
1536 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1537 systems.

1826 a value of 11 means that the largest free memory block is 2^10 pages.

Ralf Baechle25f12b32010-09-16 11:40:41 +01001900 This is a kernel model which is known a VSMP but lately has been
1901 marketesed into SMVP.
1902 Virtual SMP uses the processor's VPEs to implement virtual
1903 processors. In currently available configuration of the 34K processor
1904 this allows for a dual processor. Both processors will share the same
1905 primary caches; each will obtain the half of the TLB for it's own
1906 exclusive use. For a layman this model can be described as similar to
1907 what Intel calls Hyperthreading.

1927 On currently available 34K processors this means a Linux system will
1928 see up to 5 processors. The implementation of the SMTC kernel differs
1929 significantly from VSMP and cannot efficiently coexist in the same
1930 kernel binary so the choice between VSMP and SMTC is a compile time
1931 decision.
