Member Function Documentation
◆ executeRequest()
|
virtual |
Callback - classes are expected to inherit and override this function. It's called when a request needs to be executed (by the worker thread).
Reimplemented from ScsiController.
Definition at line 147 of file IsaAtaController.cc.
References AtaDisk::doRead(), AtaDisk::doWrite(), and AtaDisk::doWriteDirect().
◆ getName()
|
inlinevirtual |
Stores the device's name in str.
Implements AtaController.
Definition at line 42 of file IsaAtaController.h.
◆ irq()
|
virtual |
Handles a pending IRQ in thread context.
Reimplemented from AtaController.
Definition at line 162 of file IsaAtaController.cc.
References Device::getChild(), Device::getNumChildren(), and AtaDisk::irqReceived().
◆ sendCommand()
|
virtual |
Implements ScsiController.
Definition at line 135 of file IsaAtaController.cc.
◆ shutdown()
|
virtual |
Retires disk work and every hardware callback before device transfer.
Implements AtaController.
Definition at line 117 of file IsaAtaController.cc.
References RequestQueue::destroy(), AtaController::maskDiskInterrupts(), ScsiController::shutdownDiskCaches(), and AtaController::stopDiskDma().
