Member Data Documentation

◆ blocked

bool gem5::minor::Fetch1::Fetch1ThreadInfo::blocked

Blocked indication for report.

Definition at line 284 of file fetch1.hh.

Referenced by gem5::minor::Fetch1::minorTrace().

◆ pc

TheISA::PCState gem5::minor::Fetch1::Fetch1ThreadInfo::pc

Fetch PC value.

This is updated by branches from Execute, branch prediction targets from Fetch2 and by incrementing it as we fetch lines subsequent to those two sources.

Definition at line 270 of file fetch1.hh.

Referenced by gem5::minor::Fetch1::changeStream(), gem5::minor::Fetch1::fetchLine(), and gem5::minor::Fetch1::wakeupFetch().

◆ predictionSeqNum

InstSeqNum gem5::minor::Fetch1::Fetch1ThreadInfo::predictionSeqNum

Prediction sequence number.

This changes when requests from Execute or Fetch2 ask for a change of fetch address and is used to tag lines by the prediction to which they belong. Fetch2 originates prediction sequence numbers.

Definition at line 281 of file fetch1.hh.

Referenced by gem5::minor::Fetch1::fetchLine(), gem5::minor::Fetch1::FetchRequest::isDiscardable(), and gem5::minor::Fetch1::updateExpectedSeqNums().

◆ state

FetchState gem5::minor::Fetch1::Fetch1ThreadInfo::state

Definition at line 265 of file fetch1.hh.

Referenced by gem5::minor::Fetch1::changeStream(), gem5::minor::Fetch1::evaluate(), gem5::minor::Fetch1::isDrained(), gem5::minor::Fetch1::minorTrace(), gem5::minor::Fetch1::processResponse(), and gem5::minor::Fetch1::wakeupFetch().

◆ streamSeqNum

InstSeqNum gem5::minor::Fetch1::Fetch1ThreadInfo::streamSeqNum

Stream sequence number.

This changes on request from Execute and is used to tag instructions by the fetch stream to which they belong. Execute originates new prediction sequence numbers.

Definition at line 275 of file fetch1.hh.

Referenced by gem5::minor::Fetch1::evaluate(), gem5::minor::Fetch1::fetchLine(), gem5::minor::Fetch1::FetchRequest::isDiscardable(), gem5::minor::Fetch1::minorTrace(), and gem5::minor::Fetch1::updateExpectedSeqNums().

◆ wakeupGuard

bool gem5::minor::Fetch1::Fetch1ThreadInfo::wakeupGuard

Signal to guard against sleeping first cycle of wakeup.

Definition at line 287 of file fetch1.hh.

Referenced by gem5::minor::Fetch1::changeStream(), and gem5::minor::Fetch1::wakeupFetch().
