1652 This is a kernel model which is known a VSMP but lately has been
1653 marketesed into SMVP.
1654 Virtual SMP uses the processor's VPEs to implement virtual
1655 processors. In currently available configuration of the 34K processor
1656 this allows for a dual processor. Both processors will share the same
1657 primary caches; each will obtain the half of the TLB for it's own
1658 exclusive use. For a layman this model can be described as similar to
1659 what Intel calls Hyperthreading.

1678 is presenting the available TC's of the core as processors to Linux.
1679 On currently available 34K processors this means a Linux system will
1680 see up to 5 processors. The implementation of the SMTC kernel differs
1681 significantly from VSMP and cannot efficiently coexist in the same
1682 kernel binary so the choice between VSMP and SMTC is a compile time

1939 This enables support for systems with more than one CPU. If you have
1940 a system with only one CPU, like most personal computers, say N. If
1941 you have a system with more than one CPU, say Y.
1942
1943 If you say N here, the kernel will run on single and multiprocessor
1944 machines, but will use only one CPU of a multiprocessor machine. If
1945 you say Y here, the kernel will run on many, but not all,
1946 singleprocessor machines. On a singleprocessor machine, the kernel
1947 will run faster if you say N here.

1950 Y to "Enhanced Real Time Clock Support", below.
