Description:
Various files for managing Cable Based Association of
(wireless) USB devices.
The sequence of operations should be:
1. Device is plugged in.
2. The connection manager (CM) sees a device with CBA capability.
(the wusb_chid etc. files in /sys/devices/blah/OURDEVICE).
3. The CM writes the host name, supported band groups,
and the CHID (host ID) into the wusb_host_name,
wusb_host_band_groups and wusb_chid files. These
get sent to the device and the CDID (if any) for
this host is requested.
4. The CM can verify that the device's supported band
groups (wusb_device_band_groups) are compatible
with the host.
5. The CM reads the wusb_cdid file.
6. The CM looks it up its database.
- If it has a matching CHID,CDID entry, the device
has been authorized before and nothing further
needs to be done.
- If the CDID is zero (or the CM doesn't find a
matching CDID in its database), the device is
assumed to be not known. The CM may associate
the host with device by: writing a randomly
generated CDID to wusb_cdid and then a random CK
to wusb_ck (this uploads the new CC to the
device).
CMD may choose to prompt the user before
associating with a new device.
7. Device is unplugged.

Revision 7, 2007-04-19
Jean Delvare <khali@linux-fr.org>
Greg KH <greg@kroah.com>
This is a guide on how to convert I2C chip drivers from Linux 2.4 to
Linux 2.6. I have been using existing drivers (lm75, lm78) as examples.
Then I converted a driver myself (lm83) and updated this document.
Note that this guide is strongly oriented towards hardware monitoring
drivers. Many points are still valid for other type of drivers, but
others may be irrelevant.
There are two sets of points below. The first set concerns technical
changes. The second set concerns coding policy. Both are mandatory.
Although reading this guide will help you porting drivers, I suggest
you keep an eye on an already ported driver while porting your own
driver. This will help you a lot understanding what this guide
exactly means. Choose the chip driver that is the more similar to
yours for best results.
Technical changes:
* [Driver type] Any driver that was relying on i2c-isa has to be
converted to a proper isa, platform or pci driver. This is not
covered by this guide.
* [Includes] Get rid of "version.h" and <linux/i2c-proc.h>.
Includes typically look like that:
#include <linux/module.h>
#include <linux/init.h>
#include <linux/slab.h>
#include <linux/jiffies.h>
#include <linux/i2c.h>
#include <linux/hwmon.h> /* for hardware monitoring drivers */
#include <linux/hwmon-sysfs.h>
#include <linux/hwmon-vid.h> /* if you need VRM support */
#include <linux/err.h> /* for class registration */
Please respect this inclusion order. Some extra headers may be
required for a given driver (e.g. "lm75.h").
* [Addresses] SENSORS_I2C_END becomes I2C_CLIENT_END, ISA addresses
are no more handled by the i2c core. Address ranges are no more
supported either, define each individual address separately.
SENSORS_INSMOD_<n> becomes I2C_CLIENT_INSMOD_<n>.
* [Client data] Get rid of sysctl_id. Try using standard names for
register values (for example, temp_os becomes temp_max). You're
still relatively free here, but you *have* to follow the standard
names for sysfs files (see the Sysctl section below).
* [Function prototypes] The detect functions loses its flags
parameter. Sysctl (e.g. lm75_temp) and miscellaneous functions
are off the list of prototypes. This usually leaves five
prototypes:
static int lm75_attach_adapter(struct i2c_adapter *adapter);
static int lm75_detect(struct i2c_adapter *adapter, int address,
int kind);
static void lm75_init_client(struct i2c_client *client);
static int lm75_detach_client(struct i2c_client *client);
static struct lm75_data lm75_update_device(struct device *dev);
* [Sysctl] All sysctl stuff is of course gone (defines, ctl_table
and functions). Instead, you have to define show and set functions for
each sysfs file. Only define set for writable values. Take a look at an
existing 2.6 driver for details (it87 for example). Don't forget
to define the attributes for each file (this is that step that
links callback functions). Use the file names specified in
Documentation/hwmon/sysfs-interface for the individual files. Also
convert the units these files read and write to the specified ones.
If you need to add a new type of file, please discuss it on the
sensors mailing list <lm-sensors@lm-sensors.org> by providing a
patch to the Documentation/hwmon/sysfs-interface file.
* [Attach] The attach function should make sure that the adapter's
class has I2C_CLASS_HWMON (or whatever class is suitable for your
driver), using the following construct:
if (!(adapter->class & I2C_CLASS_HWMON))
return 0;
Call i2c_probe() instead of i2c_detect().
* [Detect] As mentioned earlier, the flags parameter is gone.
The type_name and client_name strings are replaced by a single
name string, which will be filled with a lowercase, short string.
The labels used for error paths are reduced to the number needed.
It is advised that the labels are given descriptive names such as
exit and exit_free. Don't forget to properly set err before
jumping to error labels. By the way, labels should be left-aligned.
Use kzalloc instead of kmalloc.
Use i2c_set_clientdata to set the client data (as opposed to
a direct access to client->data).
Use strlcpy instead of strcpy or snprintf to copy the client name.
Replace the sysctl directory registration by calls to
device_create_file. Move the driver initialization before any
sysfs file creation.
Register the client with the hwmon class (using hwmon_device_register)
if applicable.
Drop client->id.
Drop any 24RF08 corruption prevention you find, as this is now done
at the i2c-core level, and doing it twice voids it.
Don't add I2C_CLIENT_ALLOW_USE to client->flags, it's the default now.
* [Init] Limits must not be set by the driver (can be done later in
user-space). Chip should not be reset default (although a module
parameter may be used to force it), and initialization should be
limited to the strictly necessary steps.
* [Detach] Remove the call to i2c_deregister_entry. Do not log an
error message if i2c_detach_client fails, as i2c-core will now do
it for you.
Unregister from the hwmon class if applicable.
* [Update] The function prototype changed, it is now
passed a device structure, which you have to convert to a client
using to_i2c_client(dev). The update function should return a
pointer to the client data.
Don't access client->data directly, use i2c_get_clientdata(client)
instead.
Use time_after() instead of direct jiffies comparison.
* [Interface] Make sure there is a MODULE_LICENSE() line, at the bottom
of the file (after MODULE_AUTHOR() and MODULE_DESCRIPTION(), in this
order).
* [Driver] The flags field of the i2c_driver structure is gone.
I2C_DF_NOTIFY is now the default behavior.
The i2c_driver structure has a driver member, which is itself a
structure, those name member should be initialized to a driver name
string. i2c_driver itself has no name member anymore.
* [Driver model] Instead of shutdown or reboot notifiers, provide a
shutdown() method in your driver.
* [Power management] Use the driver model suspend() and resume()
callbacks instead of the obsolete pm_register() calls.
Coding policy:
* [Copyright] Use (C), not (c), for copyright.
* [Debug/log] Get rid of #ifdef DEBUG/#endif constructs whenever you
can. Calls to printk for debugging purposes are replaced by calls to
dev_dbg where possible, else to pr_debug. Here is an example of how
to call it (taken from lm75_detect):
dev_dbg(&client->dev, "Starting lm75 update\n");
Replace other printk calls with the dev_info, dev_err or dev_warn
function, as appropriate.
* [Constants] Constants defines (registers, conversions) should be
aligned. This greatly improves readability.
Alignments are achieved by the means of tabs, not spaces. Remember
that tabs are set to 8 in the Linux kernel code.
* [Layout] Avoid extra empty lines between comments and what they
comment. Respect the coding style (see Documentation/CodingStyle),
in particular when it comes to placing curly braces.
* [Comments] Make sure that no comment refers to a file that isn't
part of the Linux source tree (typically doc/chips/<chip name>),
and that remaining comments still match the code. Merging comment
lines when possible is encouraged.

Usually, you will implement a single driver structure, and instantiate

provide. A client structure holds device-specific information like the

Let's say we have a valid client structure. At some time, we will need
to gather information from the client, or write new information to the

important at this moment (perhaps we do not need to do this at all for
some obscure clients). But we need generic reading and writing routines.

Probing and attaching
=====================
The Linux I2C stack was originally written to support access to hardware
monitoring chips on PC motherboards, and thus it embeds some assumptions
that are more appropriate to SMBus (and PCs) than to I2C. One of these
assumptions is that most adapters and devices drivers support the SMBUS_QUICK
protocol to probe device presence. Another is that devices and their drivers
monitoring chips on PC motherboards, and thus used to embed some assumptions
that were more appropriate to SMBus (and PCs) than to I2C. One of these
assumptions was that most adapters and devices drivers support the SMBUS_QUICK
protocol to probe device presence. Another was that devices and their drivers
can be sufficiently configured using only such probe primitives.

Legacy Driver Binding Model
---------------------------
Initializing the driver
=======================
Most i2c devices can be present on several i2c addresses; for some this
is determined in hardware (by soldering some chip pins to Vcc or Ground),
for others this can be changed in software (by writing to specific client
registers). Some devices are usually on a specific address, but not always;
and some are even more tricky. So you will probably need to scan several
i2c addresses for your clients, and do some sort of detection to see
whether it is actually a device supported by your driver.
When the kernel is booted, or when your foo driver module is inserted,
you have to do some initializing. Fortunately, just registering the
driver module is usually enough.
To give the user a maximum of possibilities, some default module parameters
are defined to help determine what addresses are scanned. Several macros
are defined in i2c.h to help you support them, as well as a generic
detection algorithm.
static int __init foo_init(void)
{
return i2c_add_driver(&foo_driver);
}
You do not have to use this parameter interface; but don't try to use
function i2c_probe() if you don't.
static void __exit foo_cleanup(void)
{
i2c_del_driver(&foo_driver);
}
/* Substitute your own name and email address */
MODULE_AUTHOR("Frodo Looijaard <frodol@dds.nl>"
MODULE_DESCRIPTION("Driver for Barf Inc. Foo I2C devices");
Probing classes (Legacy model)
------------------------------
/* a few non-GPL license types are also allowed */
MODULE_LICENSE("GPL");
All parameters are given as lists of unsigned 16-bit integers. Lists are
terminated by I2C_CLIENT_END.
The following lists are used internally:
module_init(foo_init);
module_exit(foo_cleanup);
normal_i2c: filled in by the module writer.
A list of I2C addresses which should normally be examined.
probe: insmod parameter.
A list of pairs. The first value is a bus number (-1 for any I2C bus),
the second is the address. These addresses are also probed, as if they
were in the 'normal' list.
ignore: insmod parameter.
A list of pairs. The first value is a bus number (-1 for any I2C bus),
the second is the I2C address. These addresses are never probed.
This parameter overrules the 'normal_i2c' list only.
force: insmod parameter.
A list of pairs. The first value is a bus number (-1 for any I2C bus),
the second is the I2C address. A device is blindly assumed to be on
the given address, no probing is done.
Additionally, kind-specific force lists may optionally be defined if
the driver supports several chip kinds. They are grouped in a
NULL-terminated list of pointers named forces, those first element if the
generic force list mentioned above. Each additional list correspond to an
insmod parameter of the form force_<kind>.
Fortunately, as a module writer, you just have to define the `normal_i2c'
parameter. The complete declaration could look like this:
/* Scan 0x4c to 0x4f */
static const unsigned short normal_i2c[] = { 0x4c, 0x4d, 0x4e, 0x4f,
I2C_CLIENT_END };
/* Magic definition of all other variables and things */
I2C_CLIENT_INSMOD;
/* Or, if your driver supports, say, 2 kind of devices: */
I2C_CLIENT_INSMOD_2(foo, bar);
If you use the multi-kind form, an enum will be defined for you:
enum chips { any_chip, foo, bar, ... }
You can then (and certainly should) use it in the driver code.
Note that you *have* to call the defined variable `normal_i2c',
without any prefix!
Attaching to an adapter (Legacy model)
--------------------------------------
Whenever a new adapter is inserted, or for all adapters if the driver is
being registered, the callback attach_adapter() is called. Now is the
time to determine what devices are present on the adapter, and to register
a client for each of them.
The attach_adapter callback is really easy: we just call the generic
detection function. This function will scan the bus for us, using the
information as defined in the lists explained above. If a device is
detected at a specific address, another callback is called.
int foo_attach_adapter(struct i2c_adapter *adapter)
{
return i2c_probe(adapter,&addr_data,&foo_detect_client);
}
Remember, structure `addr_data' is defined by the macros explained above,
so you do not have to define it yourself.
The i2c_probe function will call the foo_detect_client
function only for those i2c addresses that actually have a device on
them (unless a `force' parameter was used). In addition, addresses that
are already in use (by some other registered client) are skipped.
The detect client function (Legacy model)
-----------------------------------------
The detect client function is called by i2c_probe. The `kind' parameter
contains -1 for a probed detection, 0 for a forced detection, or a positive
number for a forced detection with a chip type forced.
Returning an error different from -ENODEV in a detect function will cause
the detection to stop: other addresses and adapters won't be scanned.
This should only be done on fatal or internal errors, such as a memory
shortage or i2c_attach_client failing.
For now, you can ignore the `flags' parameter. It is there for future use.
int foo_detect_client(struct i2c_adapter *adapter, int address,
int kind)
{
int err = 0;
int i;
struct i2c_client *client;
struct foo_data *data;
const char *name = "";
/* Let's see whether this adapter can support what we need.
Please substitute the things you need here! */
if (!i2c_check_functionality(adapter,I2C_FUNC_SMBUS_WORD_DATA |
I2C_FUNC_SMBUS_WRITE_BYTE))
goto ERROR0;
/* OK. For now, we presume we have a valid client. We now create the
client structure, even though we cannot fill it completely yet.
But it allows us to access several i2c functions safely */

err = -ENOMEM;

parameter was used. */

/* The below is of course bogus */
if (foo_read(client, FOO_REG_GENERIC) != FOO_GENERIC_VALUE)
goto ERROR1;
}
/* Next, specific detection. This is especially important for `sensors'
devices. */
/* Determine the chip type. Not needed if a `force_CHIPTYPE' parameter
was used. */
if (kind <= 0) {
i = foo_read(client, FOO_REG_CHIPTYPE);
if (i == FOO_TYPE_1)
kind = chip1; /* As defined in the enum */
else if (i == FOO_TYPE_2)
kind = chip2;

return 0;
/* OK, this is not exactly good programming practice, usually. But it is
very code-efficient in this case. */
ERROR1:
kfree(data);
ERROR0:
return err;
}
Removing the client (Legacy model)
==================================
The detach_client call back function is called when a client should be
removed. It may actually fail, but only when panicking. This code is
much simpler than the attachment code, fortunately!
int foo_detach_client(struct i2c_client *client)
{
int err;
/* Try to detach the client from i2c space */
if ((err = i2c_detach_client(client)))
return err;
kfree(i2c_get_clientdata(client));
return 0;
}
Initializing the module or kernel
=================================
When the kernel is booted, or when your foo driver module is inserted,
you have to do some initializing. Fortunately, just attaching (registering)
the driver module is usually enough.
static int __init foo_init(void)
{
int res;
if ((res = i2c_add_driver(&foo_driver))) {
printk("foo: Driver registration failed, module not inserted.\n");
return res;
}
return 0;
}
static void __exit foo_cleanup(void)
{
i2c_del_driver(&foo_driver);
}
/* Substitute your own name and email address */
MODULE_AUTHOR("Frodo Looijaard <frodol@dds.nl>"
MODULE_DESCRIPTION("Driver for Barf Inc. Foo I2C devices");
/* a few non-GPL license types are also allowed */

module_init(foo_init);
module_exit(foo_cleanup);
Note that some functions are marked by `__init', and some data structures
by `__initdata'. These functions and structures can be removed after
kernel booting (or module loading) is completed.

Recipe for getting/building/running Xen/ia64 with pv_ops
--------------------------------------------------------
This recipe describes how to get xen-ia64 source and build it,
and run domU with pv_ops.
============
Requirements
============
- python
- mercurial
it (aka "hg") is an open-source source code
management software. See the below.
http://www.selenic.com/mercurial/wiki/
- git
- bridge-utils
=================================
Getting and Building Xen and Dom0
=================================
My environment is;
Machine : Tiger4
Domain0 OS : RHEL5
DomainU OS : RHEL5
1. Download source
# hg clone http://xenbits.xensource.com/ext/ia64/xen-unstable.hg
# cd xen-unstable.hg
# hg clone http://xenbits.xensource.com/ext/ia64/linux-2.6.18-xen.hg
2. # make world
3. # make install-tools
4. copy kernels and xen
# cp xen/xen.gz /boot/efi/efi/redhat/
# cp build-linux-2.6.18-xen_ia64/vmlinux.gz \
/boot/efi/efi/redhat/vmlinuz-2.6.18.8-xen
5. make initrd for Dom0/DomU
# make -C linux-2.6.18-xen.hg ARCH=ia64 modules_install \
O=$(/bin/pwd)/build-linux-2.6.18-xen_ia64
# mkinitrd -f /boot/efi/efi/redhat/initrd-2.6.18.8-xen.img \
2.6.18.8-xen --builtin mptspi --builtin mptbase \
--builtin mptscsih --builtin uhci-hcd --builtin ohci-hcd \
--builtin ehci-hcd
================================
Making a disk image for guest OS
================================
1. make file
# dd if=/dev/zero of=/root/rhel5.img bs=1M seek=4096 count=0
# mke2fs -F -j /root/rhel5.img
# mount -o loop /root/rhel5.img /mnt
# cp -ax /{dev,var,etc,usr,bin,sbin,lib} /mnt
# mkdir /mnt/{root,proc,sys,home,tmp}
Note: You may miss some device files. If so, please create them
with mknod. Or you can use tar instead of cp.
2. modify DomU's fstab
# vi /mnt/etc/fstab
/dev/xvda1 / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
3. modify inittab
set runlevel to 3 to avoid X trying to start
# vi /mnt/etc/inittab
id:3:initdefault:
Start a getty on the hvc0 console
X0:2345:respawn:/sbin/mingetty hvc0
tty1-6 mingetty can be commented out
4. add hvc0 into /etc/securetty
# vi /mnt/etc/securetty (add hvc0)
5. umount
# umount /mnt
FYI, virt-manager can also make a disk image for guest OS.
It's GUI tools and easy to make it.
==================
Boot Xen & Domain0
==================
1. replace elilo
elilo of RHEL5 can boot Xen and Dom0.
If you use old elilo (e.g RHEL4), please download from the below
http://elilo.sourceforge.net/cgi-bin/blosxom
and copy into /boot/efi/efi/redhat/
# cp elilo-3.6-ia64.efi /boot/efi/efi/redhat/elilo.efi
2. modify elilo.conf (like the below)
# vi /boot/efi/efi/redhat/elilo.conf
prompt
timeout=20
default=xen
relocatable
image=vmlinuz-2.6.18.8-xen
label=xen
vmm=xen.gz
initrd=initrd-2.6.18.8-xen.img
read-only
append=" -- rhgb root=/dev/sda2"
The append options before "--" are for xen hypervisor,
the options after "--" are for dom0.
FYI, your machine may need console options like
"com1=19200,8n1 console=vga,com1". For example,
append="com1=19200,8n1 console=vga,com1 -- rhgb console=tty0 \
console=ttyS0 root=/dev/sda2"
=====================================
Getting and Building domU with pv_ops
=====================================
1. get pv_ops tree
# git clone http://people.valinux.co.jp/~yamahata/xen-ia64/linux-2.6-xen-ia64.git/
2. git branch (if necessary)
# cd linux-2.6-xen-ia64/
# git checkout -b your_branch origin/xen-ia64-domu-minimal-2008may19
(Note: The current branch is xen-ia64-domu-minimal-2008may19.
But you would find the new branch. You can see with
"git branch -r" to get the branch lists.
http://people.valinux.co.jp/~yamahata/xen-ia64/for_eagl/linux-2.6-ia64-pv-ops.git/
is also available. The tree is based on
git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6 test)
3. copy .config for pv_ops of domU
# cp arch/ia64/configs/xen_domu_wip_defconfig .config
4. make kernel with pv_ops
# make oldconfig
# make
5. install the kernel and initrd
# cp vmlinux.gz /boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU
# make modules_install
# mkinitrd -f /boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img \
2.6.26-rc3xen-ia64-08941-g1b12161 --builtin mptspi \
--builtin mptbase --builtin mptscsih --builtin uhci-hcd \
--builtin ohci-hcd --builtin ehci-hcd
========================
Boot DomainU with pv_ops
========================
1. make config of DomU
# vi /etc/xen/rhel5
kernel = "/boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU"
ramdisk = "/boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img"
vcpus = 1
memory = 512
name = "rhel5"
disk = [ 'file:/root/rhel5.img,xvda1,w' ]
root = "/dev/xvda1 ro"
extra= "rhgb console=hvc0"
2. After boot xen and dom0, start xend
# /etc/init.d/xend start
( In the debugging case, # XEND_DEBUG=1 xend trace_start )
3. start domU
# xm create -c rhel5

Introduction
UWB is a wide-band communication protocol that is to serve also as the
low-level protocol for others (much like TCP sits on IP). Currently
these others are Wireless USB and TCP/IP, but seems Bluetooth and
Firewire/1394 are coming along.
UWB uses a band from roughly 3 to 10 GHz, transmitting at a max of
~-41dB (or 0.074 uW/MHz--geography specific data is still being
negotiated w/ regulators, so watch for changes). That band is divided in
a bunch of ~1.5 GHz wide channels (or band groups) composed of three
subbands/subchannels (528 MHz each). Each channel is independent of each
other, so you could consider them different "busses". Initially this
driver considers them all a single one.
Radio time is divided in 65536 us long /superframes/, each one divided
in 256 256us long /MASs/ (Media Allocation Slots), which are the basic
time/media allocation units for transferring data. At the beginning of
each superframe there is a Beacon Period (BP), where every device
transmit its beacon on a single MAS. The length of the BP depends on how
many devices are present and the length of their beacons.
Devices have a MAC (fixed, 48 bit address) and a device (changeable, 16
bit address) and send periodic beacons to advertise themselves and pass
info on what they are and do. They advertise their capabilities and a
bunch of other stuff.
The different logical parts of this driver are:
*
*UWB*: the Ultra-Wide-Band stack -- manages the radio and
associated spectrum to allow for devices sharing it. Allows to
control bandwidth assingment, beaconing, scanning, etc
*
*WUSB*: the layer that sits on top of UWB to provide Wireless USB.
The Wireless USB spec defines means to control a UWB radio and to
do the actual WUSB.
HWA: Host Wire adapters, your Wireless USB dongle
WUSB also defines a device called a Host Wire Adaptor (HWA), which in
mere terms is a USB dongle that enables your PC to have UWB and Wireless
USB. The Wireless USB Host Controller in a HWA looks to the host like a
[Wireless] USB controller connected via USB (!)
The HWA itself is broken in two or three main interfaces:
*
*RC*: Radio control -- this implements an interface to the
Ultra-Wide-Band radio controller. The driver for this implements a
USB-based UWB Radio Controller to the UWB stack.
*
*HC*: the wireless USB host controller. It looks like a USB host
whose root port is the radio and the WUSB devices connect to it.
To the system it looks like a separate USB host. The driver (will)
implement a USB host controller (similar to UHCI, OHCI or EHCI)
for which the root hub is the radio...To reiterate: it is a USB
controller that is connected via USB instead of PCI.
*
*WINET*: some HW provide a WiNET interface (IP over UWB). This
package provides a driver for it (it looks like a network
interface, winetX). The driver detects when there is a link up for
their type and kick into gear.
DWA: Device Wired Adaptor, a Wireless USB hub for wired devices
These are the complement to HWAs. They are a USB host for connecting
wired devices, but it is connected to your PC connected via Wireless
USB. To the system it looks like yet another USB host. To the untrained
eye, it looks like a hub that connects upstream wirelessly.
We still offer no support for this; however, it should share a lot of
code with the HWA-RC driver; there is a bunch of factorization work that
has been done to support that in upcoming releases.
WHCI: Wireless Host Controller Interface, the PCI WUSB host adapter
This is your usual PCI device that implements WHCI. Similar in concept
to EHCI, it allows your wireless USB devices (including DWAs) to connect
to your host via a PCI interface. As in the case of the HWA, it has a
Radio Control interface and the WUSB Host Controller interface per se.
There is still no driver support for this, but will be in upcoming
releases.
The UWB stack
The main mission of the UWB stack is to keep a tally of which devices
are in radio proximity to allow drivers to connect to them. As well, it
provides an API for controlling the local radio controllers (RCs from
now on), such as to start/stop beaconing, scan, allocate bandwidth, etc.
Devices and hosts: the basic structure
The main building block here is the UWB device (struct uwb_dev). For
each device that pops up in radio presence (ie: the UWB host receives a
beacon from it) you get a struct uwb_dev that will show up in
/sys/class/uwb and in /sys/bus/uwb/devices.
For each RC that is detected, a new struct uwb_rc is created. In turn, a
RC is also a device, so they also show in /sys/class/uwb and
/sys/bus/uwb/devices, but at the same time, only radio controllers show
up in /sys/class/uwb_rc.
*
[*] The reason for RCs being also devices is that not only we can
see them while enumerating the system device tree, but also on the
radio (their beacons and stuff), so the handling has to be
likewise to that of a device.
Each RC driver is implemented by a separate driver that plugs into the
interface that the UWB stack provides through a struct uwb_rc_ops. The
spec creators have been nice enough to make the message format the same
for HWA and WHCI RCs, so the driver is really a very thin transport that
moves the requests from the UWB API to the device [/uwb_rc_ops->cmd()/]
and sends the replies and notifications back to the API
[/uwb_rc_neh_grok()/]. Notifications are handled to the UWB daemon, that
is chartered, among other things, to keep the tab of how the UWB radio
neighborhood looks, creating and destroying devices as they show up or
dissapear.
Command execution is very simple: a command block is sent and a event
block or reply is expected back. For sending/receiving command/events, a
handle called /neh/ (Notification/Event Handle) is opened with
/uwb_rc_neh_open()/.
The HWA-RC (USB dongle) driver (drivers/uwb/hwa-rc.c) does this job for
the USB connected HWA. Eventually, drivers/whci-rc.c will do the same
for the PCI connected WHCI controller.
Host Controller life cycle
So let's say we connect a dongle to the system: it is detected and
firmware uploaded if needed [for Intel's i1480
/drivers/uwb/ptc/usb.c:ptc_usb_probe()/] and then it is reenumerated.
Now we have a real HWA device connected and
/drivers/uwb/hwa-rc.c:hwarc_probe()/ picks it up, that will set up the
Wire-Adaptor environment and then suck it into the UWB stack's vision of
the world [/drivers/uwb/lc-rc.c:uwb_rc_add()/].
*
[*] The stack should put a new RC to scan for devices
[/uwb_rc_scan()/] so it finds what's available around and tries to
connect to them, but this is policy stuff and should be driven
from user space. As of now, the operator is expected to do it
manually; see the release notes for documentation on the procedure.
When a dongle is disconnected, /drivers/uwb/hwa-rc.c:hwarc_disconnect()/
takes time of tearing everything down safely (or not...).
On the air: beacons and enumerating the radio neighborhood
So assuming we have devices and we have agreed for a channel to connect
on (let's say 9), we put the new RC to beacon:
*
$ echo 9 0 > /sys/class/uwb_rc/uwb0/beacon
Now it is visible. If there were other devices in the same radio channel
and beacon group (that's what the zero is for), the dongle's radio
control interface will send beacon notifications on its
notification/event endpoint (NEEP). The beacon notifications are part of
the event stream that is funneled into the API with
/drivers/uwb/neh.c:uwb_rc_neh_grok()/ and delivered to the UWBD, the UWB
daemon through a notification list.
UWBD wakes up and scans the event list; finds a beacon and adds it to
the BEACON CACHE (/uwb_beca/). If he receives a number of beacons from
the same device, he considers it to be 'onair' and creates a new device
[/drivers/uwb/lc-dev.c:uwbd_dev_onair()/]. Similarly, when no beacons
are received in some time, the device is considered gone and wiped out
[uwbd calls periodically /uwb/beacon.c:uwb_beca_purge()/ that will purge
the beacon cache of dead devices].
Device lists
All UWB devices are kept in the list of the struct bus_type uwb_bus.
Bandwidth allocation
The UWB stack maintains a local copy of DRP availability through
processing of incoming *DRP Availability Change* notifications. This
local copy is currently used to present the current bandwidth
availability to the user through the sysfs file
/sys/class/uwb_rc/uwbx/bw_avail. In the future the bandwidth
availability information will be used by the bandwidth reservation
routines.
The bandwidth reservation routines are in progress and are thus not
present in the current release. When completed they will enable a user
to initiate DRP reservation requests through interaction with sysfs. DRP
reservation requests from remote UWB devices will also be handled. The
bandwidth management done by the UWB stack will include callbacks to the
higher layers will enable the higher layers to use the reservations upon
completion. [Note: The bandwidth reservation work is in progress and
subject to change.]
Wireless USB Host Controller drivers
*WARNING* This section needs a lot of work!
As explained above, there are three different types of HCs in the WUSB
world: HWA-HC, DWA-HC and WHCI-HC.
HWA-HC and DWA-HC share that they are Wire-Adapters (USB or WUSB
connected controllers), and their transfer management system is almost
identical. So is their notification delivery system.
HWA-HC and WHCI-HC share that they are both WUSB host controllers, so
they have to deal with WUSB device life cycle and maintenance, wireless
root-hub
HWA exposes a Host Controller interface (HWA-HC 0xe0/02/02). This has
three endpoints (Notifications, Data Transfer In and Data Transfer
Out--known as NEP, DTI and DTO in the code).
We reserve UWB bandwidth for our Wireless USB Cluster, create a Cluster
ID and tell the HC to use all that. Then we start it. This means the HC
starts sending MMCs.
*
The MMCs are blocks of data defined somewhere in the WUSB1.0 spec
that define a stream in the UWB channel time allocated for sending
WUSB IEs (host to device commands/notifications) and Device
Notifications (device initiated to host). Each host defines a
unique Wireless USB cluster through MMCs. Devices can connect to a
single cluster at the time. The IEs are Information Elements, and
among them are the bandwidth allocations that tell each device
when can they transmit or receive.
Now it all depends on external stimuli.
*New device connection*
A new device pops up, it scans the radio looking for MMCs that give out
the existence of Wireless USB channels. Once one (or more) are found,
selects which one to connect to. Sends a /DN_Connect/ (device
notification connect) during the DNTS (Device Notification Time
Slot--announced in the MMCs
HC picks the /DN_Connect/ out (nep module sends to notif.c for delivery
into /devconnect/). This process starts the authentication process for
the device. First we allocate a /fake port/ and assign an
unauthenticated address (128 to 255--what we really do is
0x80 | fake_port_idx). We fiddle with the fake port status and /khubd/
sees a new connection, so he moves on to enable the fake port with a reset.
So now we are in the reset path -- we know we have a non-yet enumerated
device with an unauthorized address; we ask user space to authenticate
(FIXME: not yet done, similar to bluetooth pairing), then we do the key
exchange (FIXME: not yet done) and issue a /set address 0/ to bring the
device to the default state. Device is authenticated.
From here, the USB stack takes control through the usb_hcd ops. khubd
has seen the port status changes, as we have been toggling them. It will
start enumerating and doing transfers through usb_hcd->urb_enqueue() to
read descriptors and move our data.
*Device life cycle and keep alives*
Everytime there is a succesful transfer to/from a device, we update a
per-device activity timestamp. If not, every now and then we check and
if the activity timestamp gets old, we ping the device by sending it a
Keep Alive IE; it responds with a /DN_Alive/ pong during the DNTS (this
arrives to us as a notification through
devconnect.c:wusb_handle_dn_alive(). If a device times out, we
disconnect it from the system (cleaning up internal information and
toggling the bits in the fake hub port, which kicks khubd into removing
the rest of the stuff).
This is done through devconnect:__wusb_check_devs(), which will scan the
device list looking for whom needs refreshing.
If the device wants to disconnect, it will either die (ugly) or send a
/DN_Disconnect/ that will prompt a disconnection from the system.
*Sending and receiving data*
Data is sent and received through /Remote Pipes/ (rpipes). An rpipe is
/aimed/ at an endpoint in a WUSB device. This is the same for HWAs and
DWAs.
Each HC has a number of rpipes and buffers that can be assigned to them;
when doing a data transfer (xfer), first the rpipe has to be aimed and
prepared (buffers assigned), then we can start queueing requests for
data in or out.
Data buffers have to be segmented out before sending--so we send first a
header (segment request) and then if there is any data, a data buffer
immediately after to the DTI interface (yep, even the request). If our
buffer is bigger than the max segment size, then we just do multiple
requests.
[This sucks, because doing USB scatter gatter in Linux is resource
intensive, if any...not that the current approach is not. It just has to
be cleaned up a lot :)].
If reading, we don't send data buffers, just the segment headers saying
we want to read segments.
When the xfer is executed, we receive a notification that says data is
ready in the DTI endpoint (handled through
xfer.c:wa_handle_notif_xfer()). In there we read from the DTI endpoint a
descriptor that gives us the status of the transfer, its identification
(given when we issued it) and the segment number. If it was a data read,
we issue another URB to read into the destination buffer the chunk of
data coming out of the remote endpoint. Done, wait for the next guy. The
callbacks for the URBs issued from here are the ones that will declare
the xfer complete at some point and call it's callback.
Seems simple, but the implementation is not trivial.
*
*WARNING* Old!!
The main xfer descriptor, wa_xfer (equivalent to a URB) contains an
array of segments, tallys on segments and buffers and callback
information. Buried in there is a lot of URBs for executing the segments
and buffer transfers.
For OUT xfers, there is an array of segments, one URB for each, another
one of buffer URB. When submitting, we submit URBs for segment request
1, buffer 1, segment 2, buffer 2...etc. Then we wait on the DTI for xfer
result data; when all the segments are complete, we call the callback to
finalize the transfer.
For IN xfers, we only issue URBs for the segments we want to read and
then wait for the xfer result data.
*URB mapping into xfers*
This is done by hwahc_op_urb_[en|de]queue(). In enqueue() we aim an
rpipe to the endpoint where we have to transmit, create a transfer
context (wa_xfer) and submit it. When the xfer is done, our callback is
called and we assign the status bits and release the xfer resources.
In dequeue() we are basically cancelling/aborting the transfer. We issue
a xfer abort request to the HC, cancell all the URBs we had submitted
and not yet done and when all that is done, the xfer callback will be
called--this will call the URB callback.

bool "Add support for EVKLCD10X addon board"
help
This enables support for the EVKLCD100 (QVGA) or EVKLCD101 (VGA)
addon board for the NGW100. By enabling this the LCD controller and
AC97 controller is added as platform devices.
This choice disables the detect pin and the write-protect pin for the
MCI platform device, since it conflicts with the LCD platform device.
The MCI pins can be reenabled by editing the "add device function" but
this may break the setup for other displays that use these pins.
Choose 'Y' here if you have a EVKLCD100/101 connected to the NGW100.

Specify the target rate the internal DAC should try to match. This
will use PLL1 to generate a frequency as close as possible to this
rate.
Must be within the range 32000 to 50000, which should be suitable to
generate most other frequencies in power of 2 steps.
Ex:
48000 will also suit 24000 and 12000
44100 will also suit 22050 and 11025
32000 will also suit 16000 and 8000
