H A D | cache.hh | diff 11276:3561d002d8c7 Mon Dec 28 11:14:00 EST 2015 Andreas Hansson <andreas.hansson@arm.com> mem: Do not use sender state to track forwarded snoops in cache This patch changes how the cache tracks which snoops are forwarded, and which ones are created locally. Previously the identification was based on an empty sender state of a specific class, but this method fails to distinguish which cache actually attached the sender state. Instead we use the same mechanism as the crossbar, and keep track of the requests that have outstanding snoops. |
