Writing a device location to this file will cause

bindings. The format for the location is: DDDD:BB:DD.F.

Description:
|

Writing a device ID to this file will attempt to
|
||||
dynamically add a new device ID to a PCI device driver.
|
||||
This may allow the driver to support more hardware than
|
||||
was included in the driver's static device ID support
|
||||
table at compile time. The format for the device ID is:
|
||||
VVVV DDDD SVVV SDDD CCCC MMMM PPPP. That is Vendor ID,
|
||||
Device ID, Subsystem Vendor ID, Subsystem Device ID,
|
||||
Class, Class Mask, and Private Driver Data. The Vendor ID
|
||||
and Device ID fields are required, the rest are optional.
|
||||
Upon successfully adding an ID, the driver will probe
|
||||
for the device and attempt to bind to it. For example:
|
||||
# echo "8086 10f5" > /sys/bus/pci/drivers/foo/new_id

<title>Frame Buffer Library</title>
|
||||
|
||||
<para>
|
||||
The frame buffer drivers depend heavily on four data structures.
|
||||
These structures are declared in include/linux/fb.h. They are
|
||||
fb_info, fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs.
|
||||
The last three can be made available to and from userland.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
fb_info defines the current state of a particular video card.
|
||||
Inside fb_info, there exists a fb_ops structure which is a
|
||||
collection of needed functions to make fbdev and fbcon work.
|
||||
fb_info is only visible to the kernel.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
fb_var_screeninfo is used to describe the features of a video card
|
||||
that are user defined. With fb_var_screeninfo, things such as
|
||||
depth and the resolution may be defined.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The next structure is fb_fix_screeninfo. This defines the
|
||||
properties of a card that are created when a mode is set and can't
|
||||
be changed otherwise. A good example of this is the start of the
|
||||
frame buffer memory. This "locks" the address of the frame buffer
|
||||
memory, so that it cannot be changed or moved.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The last structure is fb_monospecs. In the old API, there was
|
||||
little importance for fb_monospecs. This allowed for forbidden things
|
||||
such as setting a mode of 800x600 on a fix frequency monitor. With
|
||||
the new API, fb_monospecs prevents such things, and if used
|
||||
correctly, can prevent a monitor from being cooked. fb_monospecs
|
||||
will not be useful until kernels 2.5.x.

<title>Serial Peripheral Interface (SPI)</title>
|
||||
<para>
|
||||
SPI is the "Serial Peripheral Interface", widely used with
|
||||
embedded systems because it is a simple and efficient
|
||||
interface: basically a multiplexed shift register.
|
||||
Its three signal wires hold a clock (SCK, often in the range
|
||||
of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and
|
||||
a "Master In, Slave Out" (MISO) data line.
|
||||
SPI is a full duplex protocol; for each bit shifted out the
|
||||
MOSI line (one per clock) another is shifted in on the MISO line.
|
||||
Those bits are assembled into words of various sizes on the
|
||||
way to and from system memory.
|
||||
An additional chipselect line is usually active-low (nCS);
|
||||
four signals are normally used for each peripheral, plus
|
||||
sometimes an interrupt.
|
||||
</para>
|
||||
<para>
|
||||
The SPI bus facilities listed here provide a generalized
|
||||
interface to declare SPI busses and devices, manage them
|
||||
according to the standard Linux driver model, and perform
|
||||
input/output operations.
|
||||
At this time, only "master" side interfaces are supported,
|
||||
where Linux talks to SPI peripherals and does not implement
|
||||
such a peripheral itself.
|
||||
(Interfaces to support implementing SPI slaves would
|
||||
necessarily look different.)
|
||||
</para>
|
||||
<para>
|
||||
The programming interface is structured around two kinds of driver,
|
||||
and two kinds of device.
|
||||
A "Controller Driver" abstracts the controller hardware, which may
|
||||
be as simple as a set of GPIO pins or as complex as a pair of FIFOs
|
||||
connected to dual DMA engines on the other side of the SPI shift
|
||||
register (maximizing throughput). Such drivers bridge between
|
||||
whatever bus they sit on (often the platform bus) and SPI, and
|
||||
expose the SPI side of their device as a
|
||||
<structname>struct spi_master</structname>.
|
||||
SPI devices are children of that master, represented as a
|
||||
<structname>struct spi_device</structname> and manufactured from
|
||||
<structname>struct spi_board_info</structname> descriptors which
|
||||
are usually provided by board-specific initialization code.
|
||||
A <structname>struct spi_driver</structname> is called a
|
||||
"Protocol Driver", and is bound to a spi_device using normal
|
||||
driver model calls.
|
||||
</para>
|
||||
<para>
|
||||
The I/O model is a set of queued messages. Protocol drivers
|
||||
submit one or more <structname>struct spi_message</structname>
|
||||
objects, which are processed and completed asynchronously.
|
||||
(There are synchronous wrappers, however.) Messages are
|
||||
built from one or more <structname>struct spi_transfer</structname>
|
||||
objects, each of which wraps a full duplex SPI transfer.
|
||||
A variety of protocol tweaking options are needed, because
|
||||
different chips adopt very different policies for how they
|
||||
use the bits transferred with SPI.

I<superscript>2</superscript>C (or without fancy typography, "I2C")
|
||||
is an acronym for the "Inter-IC" bus, a simple bus protocol which is
|
||||
widely used where low data rate communications suffice.
|
||||
Since it's also a licensed trademark, some vendors use another
|
||||
name (such as "Two-Wire Interface", TWI) for the same bus.
|
||||
I2C only needs two signals (SCL for clock, SDA for data), conserving
|
||||
board real estate and minimizing signal quality issues.
|
||||
Most I2C devices use seven bit addresses, and bus speeds of up
|
||||
to 400 kHz; there's a high speed extension (3.4 MHz) that's not yet
|
||||
found wide use.
|
||||
I2C is a multi-master bus; open drain signaling is used to
|
||||
arbitrate between masters, as well as to handshake and to
|
||||
synchronize clocks from slower clients.
|
||||

|

The Linux I2C programming interfaces support only the master
|
||||
side of bus interactions, not the slave side.
|
||||
The programming interface is structured around two kinds of driver,
|
||||
and two kinds of device.
|
||||
An I2C "Adapter Driver" abstracts the controller hardware; it binds
|
||||
to a physical device (perhaps a PCI device or platform_device) and
|
||||
exposes a <structname>struct i2c_adapter</structname> representing
|
||||
each I2C bus segment it manages.
|
||||
On each I2C bus segment will be I2C devices represented by a
|
||||
<structname>struct i2c_client</structname>. Those devices will
|
||||
be bound to a <structname>struct i2c_driver</structname>,
|
||||
which should follow the standard Linux driver model.
|
||||
(At this writing, a legacy model is more widely used.)
|
||||
There are functions to perform various I2C protocol operations; at
|
||||
this writing all such functions are usable only from task context.

<para>
|

The System Management Bus (SMBus) is a sibling protocol. Most SMBus
|
||||
systems are also I2C conformant. The electrical constraints are
|
||||
tighter for SMBus, and it standardizes particular protocol messages
|
||||
and idioms. Controllers that support I2C can also support most
|
||||
SMBus operations, but SMBus controllers don't support all the protocol
|
||||
options that an I2C controller will.
|
||||
There are functions to perform various SMBus protocol operations,
|
||||
either using I2C primitives or by issuing SMBus commands to
|
||||
i2c_adapter devices which don't support those I2C operations.

<title>Frame Buffer Library</title>

|

<para>
|
||||
The frame buffer drivers depend heavily on four data structures.
|
||||
These structures are declared in include/linux/fb.h. They are
|
||||
fb_info, fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs.
|
||||
The last three can be made available to and from userland.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
fb_info defines the current state of a particular video card.
|
||||
Inside fb_info, there exists a fb_ops structure which is a
|
||||
collection of needed functions to make fbdev and fbcon work.
|
||||
fb_info is only visible to the kernel.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
fb_var_screeninfo is used to describe the features of a video card
|
||||
that are user defined. With fb_var_screeninfo, things such as
|
||||
depth and the resolution may be defined.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The next structure is fb_fix_screeninfo. This defines the
|
||||
properties of a card that are created when a mode is set and can't
|
||||
be changed otherwise. A good example of this is the start of the
|
||||
frame buffer memory. This "locks" the address of the frame buffer
|
||||
memory, so that it cannot be changed or moved.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
The last structure is fb_monospecs. In the old API, there was
|
||||
little importance for fb_monospecs. This allowed for forbidden things
|
||||
such as setting a mode of 800x600 on a fix frequency monitor. With
|
||||
the new API, fb_monospecs prevents such things, and if used
|
||||
correctly, can prevent a monitor from being cooked. fb_monospecs
|
||||
will not be useful until kernels 2.5.x.

<title>Serial Peripheral Interface (SPI)</title>
|
||||
<para>
|
||||
SPI is the "Serial Peripheral Interface", widely used with
|
||||
embedded systems because it is a simple and efficient
|
||||
interface: basically a multiplexed shift register.
|
||||
Its three signal wires hold a clock (SCK, often in the range
|
||||
of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and
|
||||
a "Master In, Slave Out" (MISO) data line.
|
||||
SPI is a full duplex protocol; for each bit shifted out the
|
||||
MOSI line (one per clock) another is shifted in on the MISO line.
|
||||
Those bits are assembled into words of various sizes on the
|
||||
way to and from system memory.
|
||||
An additional chipselect line is usually active-low (nCS);
|
||||
four signals are normally used for each peripheral, plus
|
||||
sometimes an interrupt.
|
||||
</para>
|
||||
<para>
|
||||
The SPI bus facilities listed here provide a generalized
|
||||
interface to declare SPI busses and devices, manage them
|
||||
according to the standard Linux driver model, and perform
|
||||
input/output operations.
|
||||
At this time, only "master" side interfaces are supported,
|
||||
where Linux talks to SPI peripherals and does not implement
|
||||
such a peripheral itself.
|
||||
(Interfaces to support implementing SPI slaves would
|
||||
necessarily look different.)
|
||||
</para>
|
||||
<para>
|
||||
The programming interface is structured around two kinds of driver,
|
||||
and two kinds of device.
|
||||
A "Controller Driver" abstracts the controller hardware, which may
|
||||
be as simple as a set of GPIO pins or as complex as a pair of FIFOs
|
||||
connected to dual DMA engines on the other side of the SPI shift
|
||||
register (maximizing throughput). Such drivers bridge between
|
||||
whatever bus they sit on (often the platform bus) and SPI, and
|
||||
expose the SPI side of their device as a
|
||||
<structname>struct spi_master</structname>.
|
||||
SPI devices are children of that master, represented as a
|
||||
<structname>struct spi_device</structname> and manufactured from
|
||||
<structname>struct spi_board_info</structname> descriptors which
|
||||
are usually provided by board-specific initialization code.
|
||||
A <structname>struct spi_driver</structname> is called a
|
||||
"Protocol Driver", and is bound to a spi_device using normal
|
||||
driver model calls.
|
||||
</para>
|
||||
<para>
|
||||
The I/O model is a set of queued messages. Protocol drivers
|
||||
submit one or more <structname>struct spi_message</structname>
|
||||
objects, which are processed and completed asynchronously.
|
||||
(There are synchronous wrappers, however.) Messages are
|
||||
built from one or more <structname>struct spi_transfer</structname>
|
||||
objects, each of which wraps a full duplex SPI transfer.
|
||||
A variety of protocol tweaking options are needed, because
|
||||
different chips adopt very different policies for how they
|
||||
use the bits transferred with SPI.

This README escorted the skystar2-driver rewriting procedure. It describes the

state of the new flexcop-driver set and some internals are written down here
|
||||
too.
|
||||
|
||||
This document hopefully describes things about the flexcop and its
|
||||
device-offsprings. Goal was to write an easy-to-write and easy-to-read set of
|
||||
drivers based on the skystar2.c and other information.
|
||||
|
||||
Remark: flexcop-pci.c was a copy of skystar2.c, but every line has been
|
||||
touched and rewritten.
|
||||
|
||||
History & News
|
||||
==============
|
||||
2005-04-01 - correct USB ISOC transfers (thanks to Vadim Catana)
|
||||
|
||||
|
||||
|
||||
|
||||
General coding processing
|
||||
=========================
|
||||
|
||||
We should proceed as follows (as long as no one complains):
|
||||
|
||||
0) Think before start writing code!
|
||||
|
||||
1) rewriting the skystar2.c with the help of the flexcop register descriptions
|
||||
and splitting up the files to a pci-bus-part and a flexcop-part.
|
||||
The new driver will be called b2c2-flexcop-pci.ko/b2c2-flexcop-usb.ko for the
|
||||
device-specific part and b2c2-flexcop.ko for the common flexcop-functions.
|
||||
|
||||
2) Search for errors in the leftover of flexcop-pci.c (compare with pluto2.c
|
||||
and other pci drivers)
|
||||
|
||||
3) make some beautification (see 'Improvements when rewriting (refactoring) is
|
||||
done')
|
||||
|
||||
4) Testing the new driver and maybe substitute the skystar2.c with it, to reach
|
||||
a wider tester audience.
|
||||
|
||||
5) creating an usb-bus-part using the already written flexcop code for the pci
|
||||
card.
|
||||
|
||||
Idea: create a kernel-object for the flexcop and export all important
|
||||
functions. This option saves kernel-memory, but maybe a lot of functions have
|
||||
to be exported to kernel namespace.
|
||||
|
||||
|
||||
Current situation
|
||||
=================
|
||||
|
||||
0) Done :)
|
||||
1) Done (some minor issues left)
|
||||
2) Done
|
||||
3) Not ready yet, more information is necessary
|
||||
4) next to be done (see the table below)
|
||||
5) USB driver is working (yes, there are some minor issues)
|
||||
|
||||
What seems to be ready?
|
||||
-----------------------
|
||||
|
||||
1) Rewriting
|
||||
1a) i2c is cut off from the flexcop-pci.c and seems to work
|
||||
1b) moved tuner and demod stuff from flexcop-pci.c to flexcop-tuner-fe.c
|
||||
1c) moved lnb and diseqc stuff from flexcop-pci.c to flexcop-tuner-fe.c
|
||||
1e) eeprom (reading MAC address)
|
||||
1d) sram (no dynamic sll size detection (commented out) (using default as JJ told me))
|
||||
1f) misc. register accesses for reading parameters (e.g. resetting, revision)
|
||||
1g) pid/mac filter (flexcop-hw-filter.c)
|
||||
1i) dvb-stuff initialization in flexcop.c (done)
|
||||
1h) dma stuff (now just using the size-irq, instead of all-together, to be done)
|
||||
1j) remove flexcop initialization from flexcop-pci.c completely (done)
|
||||
1l) use a well working dma IRQ method (done, see 'Known bugs and problems and TODO')
|
||||
1k) cleanup flexcop-files (remove unused EXPORT_SYMBOLs, make static from
|
||||
non-static where possible, moved code to proper places)
|
||||
|
||||
2) Search for errors in the leftover of flexcop-pci.c (partially done)
|
||||
5a) add MAC address reading
|
||||
5c) feeding of ISOC data to the software demux (format of the isochronous data
|
||||
and speed optimization, no real error) (thanks to Vadim Catana)
|
||||
|
||||
What to do in the near future?
|
||||
--------------------------------------
|
||||
(no special order here)
|
||||
|
||||
5) USB driver
|
||||
5b) optimize isoc-transfer (submitting/killing isoc URBs when transfer is starting)

Known bugs and problems and TODO
|
||||
--------------------------------
|
||||
|
||||
1g/h/l) when pid filtering is enabled on the pci card
|
||||
|
||||
DMA usage currently:
|
||||
The DMA is splitted in 2 equal-sized subbuffers. The Flexcop writes to first
|
||||
address and triggers an IRQ when it's full and starts writing to the second
|
||||
address. When the second address is full, the IRQ is triggered again, and
|
||||
the flexcop writes to first address again, and so on.
|
||||
The buffersize of each address is currently 640*188 bytes.
|
||||
|
||||
Problem is, when using hw-pid-filtering and doing some low-bandwidth
|
||||
operation (like scanning) the buffers won't be filled enough to trigger
|
||||
the IRQ. That's why:
|
||||
|
||||
When PID filtering is activated, the timer IRQ is used. Every 1.97 ms the IRQ
|
||||
is triggered. Is the current write address of DMA1 different to the one
|
||||
during the last IRQ, then the data is passed to the demuxer.
|
||||
|
||||
There is an additional DMA-IRQ-method: packet count IRQ. This isn't
|
||||
implemented correctly yet.
|
||||
|
||||
The solution is to disable HW PID filtering, but I don't know how the DVB
|
||||
API software demux behaves on slow systems with 45MBit/s TS.
|
||||
|
||||
Solved bugs :)
|
||||
--------------
|
||||
1g) pid-filtering (somehow pid index 4 and 5 (EMM_PID and ECM_PID) aren't
|
||||
working)
|
||||
SOLUTION: also index 0 was affected, because net_translation is done for
|
||||
these indexes by default
|
||||
|
||||
5b) isochronous transfer does only work in the first attempt (for the Sky2PC
|
||||
USB, Air2PC is working) SOLUTION: the flexcop was going asleep and never really
|
||||
woke up again (don't know if this need fixes, see
|
||||
flexcop-fe-tuner.c:flexcop_sleep)
|
||||
|
||||
NEWS: when the driver is loaded and unloaded and loaded again (w/o doing
|
||||
anything in the while the driver is loaded the first time), no transfers take
|
||||
place anymore.
|
||||
|
||||
Improvements when rewriting (refactoring) is done
|
||||
=================================================
|
||||
|
||||
- split sleeping of the flexcop (misc_204.ACPI3_sig = 1;) from lnb_control
|
||||
(enable sleeping for other demods than dvb-s)
|
||||
- add support for CableStar (stv0297 Microtune 203x/ALPS) (almost done, incompatibilities with the Nexus-CA)
|
||||
|
||||
Debugging
|
||||
---------
|
||||
- add verbose debugging to skystar2.c (dump the reg_dw_data) and compare it
|
||||
with this flexcop, this is important, because i2c is now using the
|
||||
flexcop_ibi_value union from flexcop-reg.h (do you have a better idea for
|
||||
that, please tell us so).
|
||||
|
||||
Everything which is identical in the following table, can be put into a common
|
||||
flexcop-module.
|
||||
|
||||
PCI USB
|
||||
-------------------------------------------------------------------------------
|
||||
Different:
|
||||
Register access: accessing IO memory USB control message
|
||||
I2C bus: I2C bus of the FC USB control message
|
||||
Data transfer: DMA isochronous transfer
|
||||
EEPROM transfer: through i2c bus not clear yet
|
||||
|
||||
Identical:
|
||||
Streaming: accessing registers
|
||||
PID Filtering: accessing registers
|
||||
Sram destinations: accessing registers
|
||||
Tuner/Demod: I2C bus
