MIPS: Kconfig: Fix and clarify kconfig help text for VSMP and SMTC.
Only VSMP was known as SMVP and generally the help text was too short to be helpful. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

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

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