bool port_implemented ()

These flag-access functions should require holding the port lock.

In their current use, they frequently access them unlocked. This

will be fixed and thread annotations will be added in future CLs.

zx_status_t Queue (SataTransaction * txn)

Defined at line 198 of file ../../src/devices/block/drivers/ahci/port.cc

bool Complete ()

Complete in-progress transactions.

Returns true if there remain transactions in progress.

Defined at line 213 of file ../../src/devices/block/drivers/ahci/port.cc

bool ProcessQueued ()

Process incoming transaction queue and run them.

Returns true if transactions were added (are now in progress)

Defined at line 271 of file ../../src/devices/block/drivers/ahci/port.cc

bool HandleIrq ()

HandleIrq does not lock the port or check whether it is valid.

It is assumed that an invalid port can not have scheduled operations that trigger an interrupt.

The port may have been disabled or unplugged, but is still valid.

Defined at line 476 of file ../../src/devices/block/drivers/ahci/port.cc

void TestSetRunning (SataTransaction * txn, uint32_t slot)

Mark transaction as running without going through the Queue path.

Does not modify bus registers.
