Member Data Documentation

◆ blocked

bool gem5::minor::Fetch1::Fetch1ThreadInfo::blocked = false

Blocked indication for report.

Definition at line 278 of file fetch1.hh.

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

◆ fetchAddr

Addr gem5::minor::Fetch1::Fetch1ThreadInfo::fetchAddr = 0

The address we're currently fetching lines from.

Definition at line 264 of file fetch1.hh.

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

◆ pc

std::unique_ptr<PCStateBase> gem5::minor::Fetch1::Fetch1ThreadInfo::pc

Fetch PC value.

This is updated by branches from Execute, branch prediction targets from Fetch2. This is only valid immediately following a redirect from one of those two sources.

Definition at line 261 of file fetch1.hh.

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

◆ predictionSeqNum

InstSeqNum gem5::minor::Fetch1::Fetch1ThreadInfo::predictionSeqNum = InstId::firstPredictionSeqNum

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.

◆ streamSeqNum

InstSeqNum gem5::minor::Fetch1::Fetch1ThreadInfo::streamSeqNum = InstId::firstStreamSeqNum

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.

◆ wakeupGuard

bool gem5::minor::Fetch1::Fetch1ThreadInfo::wakeupGuard = false

Signal to guard against sleeping first cycle of wakeup.
