Hi all,
I am working on USB data monitoring on Fedora Core 9. Kernel 2.6.25 has a built-in module (the one that isn't loadable, but compiles and links statically with the kernel during compilation) to snoop USB data. It is in <kernel_source_code>/drivers/usb/mon/.
I need to know if I can... (0 Replies)

Hi All,
Is there a max number of slabs that can be used per kernel module? I'm having a tough time finding out that kind of information, but the array 'node_zonelists' (mmzone.h) has a size of 5. I just want to avoid buffer overruns and other bad stuff.
Cheers,

DRIVER_MODULE(9) BSD Kernel Developer's Manual DRIVER_MODULE(9)
NAME
DRIVER_MODULE -- kernel driver declaration macro
SYNOPSIS
#include <sys/param.h>
#include <sys/kernel.h>
#include <sys/bus.h>
#include <sys/module.h>
DRIVER_MODULE(name, busname, driver_t driver, devclass_t devclass, modeventhand_t evh, void *arg);
MULTI_DRIVER_MODULE(name, busname, driver_t drivers[], devclass_t devclass, modeventhand_t evh, void *arg);
DESCRIPTION
The DRIVER_MODULE() macro declares a kernel driver. DRIVER_MODULE() expands to the real driver declaration, where the phrase name is used as
the naming prefix for the driver and its functions. Note that it is supplied as plain text, and not a char or char *.
busname is the parent bus of the driver (PCI, ISA, PPBUS and others), e.g. 'pci', 'isa', or 'ppbus'.
The identifier used in DRIVER_MODULE() can be different from the driver name. Also, the same driver identifier can exist on different
busses, which is a pretty clean way of making front ends for different cards using the same driver on the same or different busses. For
example, the following is allowed:
DRIVER_MODULE(foo, isa, foo_driver, foo_devclass, NULL, NULL);
DRIVER_MODULE(foo, pci, foo_driver, foo_devclass, NULL, NULL);
driver is the driver of type driver_t, which contains the information about the driver and is therefore one of the two most important parts
of the call to DRIVER_MODULE().
The devclass argument contains the kernel-internal information about the device, which will be used within the kernel driver module.
The evh argument is the event handler which is called when the driver (or module) is loaded or unloaded (see module(9)).
The arg is unused at this time and should be a NULL pointer.
MULTI_DRIVER_MODULE() is a special version of DRIVER_MODULE(), which takes a list of drivers instead of a single driver instance.
