Member Function Documentation

conclude()

void dxd::pci::conclude ( )

inlineoverrideprotectedinherited

IOKit: Main driver finalization.

conclude() is one of the driver-supplied routines that is called before a driver is to be removed. It is responsible for freeing all resource the driver acquired during launch().

eumb()

volatile unsigned int * dxd::ppc::eumb ( eumb offset )

inline

pointer to eumb register

Use with eumb register set for use in eumb function to retrieve pointer of device register.

fill32()

template<endian endian_t>

void dxd::ppc::fill32 ( unsigned int pattern, unsigned int inbound, size_t size32 )

inline

fill ppc inbound range with 32bit pattern

Fill the ppc inbound range with a 32bit pattern. Since this function needs to access the inbound translation window this call blocks.

Parameters

pattern	32bit pattern to be written to inbound ppc range
inbound	ppc inbound range start address to be filled
size32	amount of 32bit values written to inbound range

Template Parameters

endian_t

indicates the endianism of the firewire device

Here is the call graph for this function:

i2o()

os_result dxd::ppc::i2o ( const unsigned int * msg, size_t size )

inline

i2o message send

Copies the message contents to PCI window and

writes inbound queue to post the message.

Here is the call graph for this function:

irq_disable()

virtual os_result dxd::pci::irq_disable ( )

inlineprotectedvirtualinherited

IOKit: disable hardware irq handler.

irq_enable()

virtual os_result dxd::pci::irq_enable ( )

inlineprotectedvirtualinherited

IOKit: enable hardware irq handler.

isr_odi()

virtual os_result dxd::ppc::isr_odi ( unsigned int dbr )

inlineprotectedvirtual

outbound doorbell interrupt handler

Parameters

dbr	doorbell register

isr_opqi()

virtual os_result dxd::ppc::isr_opqi ( unsigned int fpqr )

inlineprotectedvirtual

outbound messsage interrupt handler

Parameters

fpqr	FIFO pointer queue register

launch()

os_result dxd::ppc::launch ( )

inlineoverrideprotected

IOKit: Main driver entry.

launch() is one of the dynax driver frameword-supplied routines that is called after this driver is loaded. It is responsible for initializing the driver.

Checks if there are exactly two PCI memory windows.
