# 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 for largest
|
|
# block sizes [though few percent better for not so long ones]. All
|
|
# this based on suggestions from David Miller.
