Remove that example. It was obsolete even before 3.0 release.

$NetBSD: README,v 1.4 2005/12/11 12:24:48 christos Exp $
|
||||
|
||||
The auich module is provided as an example of the use of the pcilkm layer.
|
||||
|
||||
It should be noted that it has limitations. First, it cannot be unloaded.
|
||||
This is because auich(4) does not provide a detach() method, thus neither
|
||||
the underlying audio(4) device nor the auich(4) device can be detached.
|
||||
Therefore the pcilkm layer prevents the auich module from being removed.
|
||||
|
||||
Second, auich(4) has some dependencies, listed in dev/pci/files.pci, which
|
||||
are required for the module to work properly. This includes audio, ac97
|
||||
and some other components that may interact with each other.
|
||||
|
||||
For example, the aurateconv component, needed by auich(4), is optional in
|
||||
the NetBSD kernel for audio(4) operations, and does not change the API.
|
||||
If aurateconv is lacking, loading the auich module will result in a
|
||||
panic. It might be considered as a bug, but it is not really relevant
|
||||
since most of the kernel is not ready for device drivers modules.
|
||||
|
||||
To test that module, I recommend that you keep in your kernel config file
|
||||
the definition for auvia* at pci?, since auvia(4) has the same list of
|
||||
requirements as auich(4).

|

.Sh NAME
|
||||
.Nm pcilkm
|
||||
.Nd Loadable Kernel Module that can load PCI device drivers
|
||||
.Sh SYNOPSIS
|
||||
.In sys/lkm.h
|
||||
.In lkm/dev/pcilkm/pcilkm.h
|
||||
.Fn PCILKM_DECLARE name class attrs
|
||||
.Sh DESCRIPTION
|
||||
.Nm
|
||||
is meant to be a layer between the kernel and loadable PCI device drivers,
|
||||
making the necessary operations to glue the driver to
|
||||
.Xr autoconf 9 .
|
||||
.Pp
|
||||
It works by catching the usual load/unload calls of the LKM framework.
|
||||
The
|
||||
.Xr autoconf 9
|
||||
structures are updated to reflect the addition of the new driver.
|
||||
Then
|
||||
.Nm
|
||||
performs a scan of the PCI buses that will call the
|
||||
.Fn match
|
||||
and
|
||||
.Fn attach
|
||||
functions of the driver as it would be the case for a compiled-in
|
||||
PCI device driver.
|
||||
.Pp
|
||||
.Nm
|
||||
was designed to minimize the difference between a regular compiled-in
|
||||
driver and a loadable driver.
|
||||
The programmer only has to add the required
|
||||
.Em MOD_*
|
||||
directive, depending on the type of the driver,
|
||||
and then attach the driver to the
|
||||
.Nm
|
||||
framework by using the
|
||||
.Fn PCILKM_DECLARE
|
||||
macro.
|
||||
.Pp
|
||||
The
|
||||
.Em name
|
||||
argument is used to build various structure names and must match the name
|
||||
given to the
|
||||
.Fn CFATTACH_DECL
|
||||
macro.
|
||||
Since the
|
||||
.Em struct cfattach
|
||||
variable is referenced by
|
||||
.Fn PCILKM_DECLARE ,
|
||||
the
|
||||
.Fn CFATTACH_DECL
|
||||
directive must appear earlier in the source file.
|
||||
.Pp
|
||||
The
|
||||
.Em class
|
||||
and
|
||||
.Em attrs
|
||||
arguments are the ones
|
||||
.Xr config 1
|
||||
would write down in the
|
||||
.Fn CFDRIVER_DECL
|
||||
directive of that driver if it was compiled-in and properly referenced in
|
||||
the kernel configuration file.
|
||||
The values
|
||||
.Em DV_DULL
|
||||
and
|
||||
.Em NULL
|
||||
will fit in most cases, unless you want to have other devices attached to
|
||||
the managed device, in which case a properly built
|
||||
.Em attrs
|
||||
structure has to be passed.
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
module must be loaded along with its symbol table to be useful,
|
||||
since actual device driver loaded afterwards reference an exported
|
||||
function.
|
||||
Therefore,
|
||||
.Xr ksyms 4
|
||||
support is required in the kernel.

||||
