* Raw binary format and API
TBD
The overall architecture of the API is about the same as the one above,
only the events are delivered in binary format. Each event is sent in
the following structure (its name is made up, so that we can refer to it):
struct usbmon_packet {
u64 id; /* 0: URB ID - from submission to callback */
unsigned char type; /* 8: Same as text; extensible. */
unsigned char xfer_type; /* ISO (0), Intr, Control, Bulk (3) */
unsigned char epnum; /* Endpoint number and transfer direction */
unsigned char devnum; /* Device address */
u16 busnum; /* 12: Bus number */
char flag_setup; /* 14: Same as text */
char flag_data; /* 15: Same as text; Binary zero is OK. */
s64 ts_sec; /* 16: gettimeofday */
s32 ts_usec; /* 24: gettimeofday */
int status; /* 28: */
unsigned int length; /* 32: Length of data (submitted or actual) */
unsigned int len_cap; /* 36: Delivered length */
unsigned char setup[8]; /* 40: Only for Control 'S' */
}; /* 48 bytes total */
These events can be received from a character device by reading with read(2),
with an ioctl(2), or by accessing the buffer with mmap.
The character device is usually called /dev/usbmonN, where N is the USB bus
number. Number zero (/dev/usbmon0) is special and means "all buses".
However, this feature is not implemented yet. Note that specific naming
policy is set by your Linux distribution.
If you create /dev/usbmon0 by hand, make sure that it is owned by root
and has mode 0600. Otherwise, unpriviledged users will be able to snoop
keyboard traffic.
The following ioctl calls are available, with MON_IOC_MAGIC 0x92:
MON_IOCQ_URB_LEN, defined as _IO(MON_IOC_MAGIC, 1)
This call returns the length of data in the next event. Note that majority of
events contain no data, so if this call returns zero, it does not mean that
no events are available.
MON_IOCG_STATS, defined as _IOR(MON_IOC_MAGIC, 3, struct mon_bin_stats)
The argument is a pointer to the following structure:
struct mon_bin_stats {
u32 queued;
u32 dropped;
};
The member "queued" refers to the number of events currently queued in the
buffer (and not to the number of events processed since the last reset).
The member "dropped" is the number of events lost since the last call
to MON_IOCG_STATS.
MON_IOCT_RING_SIZE, defined as _IO(MON_IOC_MAGIC, 4)
This call sets the buffer size. The argument is the size in bytes.
The size may be rounded down to the next chunk (or page). If the requested
size is out of [unspecified] bounds for this kernel, the call fails with
-EINVAL.
MON_IOCQ_RING_SIZE, defined as _IO(MON_IOC_MAGIC, 5)
This call returns the current size of the buffer in bytes.
MON_IOCX_GET, defined as _IOW(MON_IOC_MAGIC, 6, struct mon_get_arg)
This call waits for events to arrive if none were in the kernel buffer,
then returns the first event. Its argument is a pointer to the following
structure:
struct mon_get_arg {
struct usbmon_packet *hdr;
void *data;
size_t alloc; /* Length of data (can be zero) */
};
Before the call, hdr, data, and alloc should be filled. Upon return, the area
pointed by hdr contains the next event structure, and the data buffer contains
the data, if any. The event is removed from the kernel buffer.
MON_IOCX_MFETCH, defined as _IOWR(MON_IOC_MAGIC, 7, struct mon_mfetch_arg)
This ioctl is primarily used when the application accesses the buffer
with mmap(2). Its argument is a pointer to the following structure:
struct mon_mfetch_arg {
uint32_t *offvec; /* Vector of events fetched */
uint32_t nfetch; /* Number of events to fetch (out: fetched) */
uint32_t nflush; /* Number of events to flush */
};
The ioctl operates in 3 stages.
First, it removes and discards up to nflush events from the kernel buffer.
The actual number of events discarded is returned in nflush.
Second, it waits for an event to be present in the buffer, unless the pseudo-
device is open with O_NONBLOCK.
Third, it extracts up to nfetch offsets into the mmap buffer, and stores
them into the offvec. The actual number of event offsets is stored into
the nfetch.
MON_IOCH_MFLUSH, defined as _IO(MON_IOC_MAGIC, 8)
This call removes a number of events from the kernel buffer. Its argument
is the number of events to remove. If the buffer contains fewer events
than requested, all events present are removed, and no error is reported.
This works when no events are available too.
FIONBIO
The ioctl FIONBIO may be implemented in the future, if there's a need.
In addition to ioctl(2) and read(2), the special file of binary API can
be polled with select(2) and poll(2). But lseek(2) does not work.
* Memory-mapped access of the kernel buffer for the binary API
The basic idea is simple:
To prepare, map the buffer by getting the current size, then using mmap(2).
Then, execute a loop similar to the one written in pseudo-code below:
struct mon_mfetch_arg fetch;
struct usbmon_packet *hdr;
int nflush = 0;
for (;;) {
fetch.offvec = vec; // Has N 32-bit words
fetch.nfetch = N; // Or less than N
fetch.nflush = nflush;
ioctl(fd, MON_IOCX_MFETCH, &fetch); // Process errors, too
nflush = fetch.nfetch; // This many packets to flush when done
for (i = 0; i < nflush; i++) {
hdr = (struct ubsmon_packet *) &mmap_area[vec[i]];
if (hdr->type == '@') // Filler packet
continue;
caddr_t data = &mmap_area[vec[i]] + 64;
process_packet(hdr, data);
}
}
Thus, the main idea is to execute only one ioctl per N events.
Although the buffer is circular, the returned headers and data do not cross
the end of the buffer, so the above pseudo-code does not need any gathering.

Video Output Switcher Control
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2006 luming.yu@intel.com
The output sysfs class driver provides an abstract video output layer that
can be used to hook platform specific methods to enable/disable video output
device through common sysfs interface. For example, on my IBM ThinkPad T42
laptop, The ACPI video driver registered its output devices and read/write
method for 'state' with output sysfs class. The user interface under sysfs is:

help
kexec is a system call that implements the ability to shutdown your
current kernel, and to start another kernel. It is like a reboot
but it is indepedent of the system firmware. And like a reboot
you can start any kernel with it, not just Linux.
The name comes from the similiarity to the exec system call.
It is an ongoing process to be certain the hardware in a machine
is properly shutdown, so do not be surprised if this code does not
initially work for you. It may help to enable device hotplugging
support. As of this writing the exact hardware interface is
strongly in flux, so no good recommendation can be made.
