Detailed Description

The device extension for the device

Definition at line 95 of file cbm_driver.h.

Field Documentation

DEVICE_EXTENSION_s::ARCH_DEVICE_EXTENSION

the architecture specific stuff

Definition at line 99 of file cbm_driver.h.

BOOLEAN DEVICE_EXTENSION_s::Eoi

TRUE -> we received an EOI over the bus

Definition at line 171 of file cbm_driver.h.

BOOLEAN DEVICE_EXTENSION_s::IecBusy

Remember if this device is busy

Definition at line 168 of file cbm_driver.h.

IEC_CABLETYPE DEVICE_EXTENSION_s::IecCable

The type of the cable, as determined by the automatism: IEC_CABLETYPE_AUTO –> autodetect IEC_CABLETYPE_XM –> non-inverted (XM1541) IEC_CABLETYPE_XA –> inverted (XA1541)

Definition at line 127 of file cbm_driver.h.

CABLESTATE DEVICE_EXTENSION_s::IecCableState

The state the cable detection is in

Definition at line 137 of file cbm_driver.h.

IEC_CABLETYPE DEVICE_EXTENSION_s::IecCableUserSet

The type of the cable, as set by the user

Definition at line 132 of file cbm_driver.h.

UCHAR DEVICE_EXTENSION_s::IecInEor

EOR mask for inputting from the parallel port

Definition at line 146 of file cbm_driver.h.

UCHAR DEVICE_EXTENSION_s::IecOutBits

The current state of the output bits of the parallel port

Definition at line 140 of file cbm_driver.h.

UCHAR DEVICE_EXTENSION_s::IecOutEor

EOR mask for outputting on the parallel port

Definition at line 143 of file cbm_driver.h.

ULONG DEVICE_EXTENSION_s::IrqCount

how many Irqs should we wait in cbmiec_interrupt (for cbmiec_wait_for_listener()? This determines if we want to schedule an EOI (=2) or not (=1). =0 means that the interrupt is not interesting for us.

Definition at line 114 of file cbm_driver.h.

BOOLEAN DEVICE_EXTENSION_s::IsSMP

FLAG: We are running on an SMP or an HT machine

Definition at line 117 of file cbm_driver.h.

PUCHAR DEVICE_EXTENSION_s::ParPortEcpPortAddress

Start address of the ECP portion of the parallel port. If this is not an ECP port, this is 0.

Definition at line 107 of file cbm_driver.h.

PUCHAR DEVICE_EXTENSION_s::ParPortPortAddress

Start address of the parallel port in the I/O address space

Definition at line 102 of file cbm_driver.h.
