H A D | mshr.hh | diff 12599:43ade6cf92b7 Mon Mar 12 06:11:00 EDT 2018 Nikos Nikoleris <nikos.nikoleris@arm.com> mem-cache: Allow clean operations when block allocation fails Block allocation can fail when there is an in-service MSHR that operates on the victim block. This can happed due to: * an upgrade operation: a request that needs a writable copy of the block finds a shared (non-writable) copy of the block in the cache and has allocates an MSHR for the pending upgrade operation, or * a clean operation: a clean request finds a dirty copy of the block and allocates an MSHR for the pending clean operation. This changes relaxes an assertion to allow for the 2nd case (cache clean operations).
