<p>The new PCID implementation uses an algorithm described in
|
||||
the U. Vahalia book "UNIX Internals: The New Frontiers". The
|
||||
algorithm is already used, for example, by the MIPS pmap for
|
||||
assigning Address Space Identifiers (ASIDs) to software-managed
|
||||
TLB entries. The pmap
|
||||
maintains a per-CPU generation count, which is assigned to the
|
||||
next unused PCID when the context is activated on CPU. TLB
|
||||
invalidation includes resetting the generation count, which
|
||||
causes reallocation of the PCID when a context switch is
|
||||
performed. As result, the new implementation issues exactly
|
||||
the same amount of shootdown IPIs as a pmap which does not
|
||||
utilize PCID.</p>

the address space switching code from assembler to C source,
