Member Typedef Documentation

◆ flags_t

typedef uint32_t SST::Interfaces::SimpleMem::Request::flags_t

Flag type

◆ id_t

typedef uint64_t SST::Interfaces::SimpleMem::Request::id_t

Request ID type

Member Enumeration Documentation

◆ Command

enum SST::Interfaces::SimpleMem::Request::Command

Commands and responses possible with a Request object.

Enumerator
Read	Issue a Read from Memory
Write	Issue a Write to Memory
ReadResp	Response from Memory to a Read
WriteResp	Response from Memory to a Write
FlushLine	Cache flush request - writeback specified line throughout memory system
FlushLineInv	Cache flush request - writeback and invalidate specified line throughout memory system
FlushLineResp	Response to FlushLine; flag F_FLUSH_SUCCESS indicates success or failure
TxBegin	Start a new transaction
TxEnd	End the current lowest transaction
CustomCmd	Custom memory command: Must also set custCmd opcode

◆ Flags

enum SST::Interfaces::SimpleMem::Request::Flags

Flags to specify conditions on a Request.

Enumerator
F_NONCACHEABLE	This request should not be cached
F_LOCKED	This request should be locked. A LOCKED read should be soon followed by a LOCKED write (to unlock)
F_FLUSH_SUCCESS	This flag is set if the flush was successful. Flush may fail due to LOCKED lines
