NAME
dummy_cs - PCMCIA dummy device driver
SYNOPSIS
insmod dummy_cs.o [pc_debug=n] [free_ports=n] [irq_list=i,j,...]
DESCRIPTION
The dummy_cs module has two purposes. It is intended as a
demonstration of how to write the PCMCIA interface code for a client
driver, and the source code is heavily commented. It is also written
to function as a sort of generic ‘‘point enabler’’: when bound to any
PCMCIA IO card, it will read the card’s Configuration Information
Structure, and configure the card appropriately. The configuration
includes setting up IO and memory windows, configuring the card for
interrupts, and initializing the card’s PCMCIA configuration registers.
It turns out that many cards report incomplete or inaccurate
configuration information, due to vendor carelessness and the
complexity of the data format. A vendor driver can generally take for
granted many configuration details, so there is not much incentive for
vendors to ensure that the on-card information is complete. Thus, the
dummy_cs module is limited by its generality: since it makes no
assumptions about card types, it is forced to rely on the card
information, for better or worse.
PARAMETERS
pc_debug=n
Selects the PCMCIA debugging level. This parameter is only
available if the module is compiled with debugging enabled. A
non-zero value enables debugging.
free_ports=n
A flag indicating if the IO ports allocated for the card should
be freed from the kernel resource maps. This is useful if the
dummy driver is being used to configure a card in preparation
for loading a specific PCMCIA-unaware driver. The default is 0
(false).
irq_list=i,j,...
Specifies the set of interrupts that may be allocated by this
driver.
