Detailed Description

The controller for up to two AtaDisks. This uses a background thread and a request queue.

Member Function Documentation

uint64_t IsaAtaController::executeRequest ( uint64_t  p1, uint64_t  p2, uint64_t  p3, uint64_t  p4, uint64_t  p5, uint64_t  p6, uint64_t  p7, uint64_t  p8  )

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 152 of file IsaAtaController.cc.

References AtaDisk::doRead(), and AtaDisk::doWrite().

Referenced by getName().

Here is the caller graph for this function:

virtual void IsaAtaController::getName ( String &  str )

inlinevirtual

Stores the device's name in str.

Implements AtaController.

Definition at line 42 of file IsaAtaController.h.

References executeRequest(), and irq().

bool IsaAtaController::irq ( irq_id_t  number, InterruptState &  state  )

virtual

Called when the handler is registered with the irq manager and the irq occurred

Note

If this function returns false you have to call IrqManager::acknowledgeIrq() when you removed the interrupt reason.

Parameters

[in]

number

the irq number

Returns

should return true, if the interrupt reason was removed, or false otherwise

Reimplemented from AtaController.

Definition at line 165 of file IsaAtaController.cc.
