# Linux Kernel Module Cheat
The perfect emulation setup to study and develop the <<linux-kernel>> v5.9.2, kernel modules, <<qemu-buildroot-setup,QEMU>>, <<gem5-buildroot-setup,gem5>> and x86_64, ARMv7 and ARMv8 <<userland-assembly,userland>> and <<baremetal-setup,baremetal>> assembly, <<c,ANSI C>>, <<cpp,C++>> and <<posix,POSIX>>. <<gdb>> and <<kgdb>> just work. Powered by <<about-the-qemu-buildroot-setup,Buildroot>> and <<about-the-baremetal-setup,crosstool-NG>>. Highly automated. Thoroughly documented. Automated <<test-this-repo,tests>>.

###### 24.22.4.2.20. TimingSimpleCPU analysis #20

Schedules `PacketQueue::processSendEvent` through:

    EventManager::schedule
    PacketQueue::schedSendEvent
    PacketQueue::schedSendTiming
    QueuedSlavePort::schedTimingResp
    CoherentXBar::recvTimingResp
    CoherentXBar::CoherentXBarMasterPort::recvTimingResp
    TimingResponseProtocol::sendResp
    SlavePort::sendTimingResp
    RespPacketQueue::sendTiming
    PacketQueue::sendDeferredPacket
    PacketQueue::processSendEvent

From this backtrace, we see that this event is happening as the fetch reply packet finally comes back from DRAM.
