# Specific mode implementations for SPARC T4 modules.
|
||||
# Specific modes implementations for SPARC Architecture 2011. There
|
||||
# is T4 dependency though, an ASI value that is not specified in the
|
||||
# Architecture Manual. But as SPARC universe is rather monocultural,
|
||||
# we imply that processor capable of executing crypto instructions
|
||||
# can handle the ASI in question as well. This means that we ought to
|
||||
# keep eyes open when new processors emerge...
|
||||
#
|
||||
# As for above mentioned ASI. It's so called "block initializing
|
||||
# store" which cancels "read" in "read-update-write" on cache lines.
|
||||
# This is "cooperative" optimization, as it reduces overall pressure
|
||||
# on memory interface. Benefits can't be observed/quantified with
|
||||
# usual benchmarks, on the contrary you can notice that single-thread
|
||||
# performance for parallelizable modes is ~1.5% worse. Special note
|
||||
# about commented 'membar' instructions, otherwise recommended by
|
||||
# manual. Rationale is following. Memory view is consistent from
|
||||
# viewpoint of processor executing the code even when ASI in question
|
||||
# is used. If thread on another processor has to access the result,
|
||||
# its availability would have to be mediated and it can be done only
|
||||
# through a syncronization operation which would requre ... 'membar'.
|
||||
# All this based on suggestions from David Miller.
