This page describes how to make calls to the firmware api.
How to call
===========
The preferred calling convention is known as the firmware mailbox. The
mailboxes are basically a fixed length array that serves as the call-stack.
Firmware mailboxes can be located by searching the encoder and decoder memory
for a 16 byte signature. That signature will be located on a 256-byte boundary.
Signature:
0x78, 0x56, 0x34, 0x12, 0x12, 0x78, 0x56, 0x34,
0x34, 0x12, 0x78, 0x56, 0x56, 0x34, 0x12, 0x78
The firmware implements 20 mailboxes of 20 32-bit words. The first 10 are
reserved for API calls. The second 10 are used by the firmware for event
notification.
Index Name
----- ----
0 Flags
1 Command
2 Return value
3 Timeout
4-19 Parameter/Result
The flags are defined in the following table. The direction is from the
perspective of the firmware.
Bit Direction Purpose
--- --------- -------
2 O Firmware has processed the command.
1 I Driver has finished setting the parameters.
0 I Driver is using this mailbox.
The command is a 32-bit enumerator. The API specifics may be found in the
fw-*-api.txt documents.
The return value is a 32-bit enumerator. Only two values are currently defined:
0=success and -1=command undefined.
There are 16 parameters/results 32-bit fields. The driver populates these fields
with values for all the parameters required by the call. The driver overwrites
these fields with result values returned by the call. The API specifics may be
found in the fw-*-api.txt documents.
The timeout value protects the card from a hung driver thread. If the driver
doesn't handle the completed call within the timeout specified, the firmware
will reset that mailbox.
To make an API call, the driver iterates over each mailbox looking for the
first one available (bit 0 has been cleared). The driver sets that bit, fills
in the command enumerator, the timeout value and any required parameters. The
driver then sets the parameter ready bit (bit 1). The firmware scans the
mailboxes for pending commands, processes them, sets the result code, populates
the result value array with that call's return values and sets the call
complete bit (bit 2). Once bit 2 is set, the driver should retrieve the results
and clear all the flags. If the driver does not perform this task within the
time set in the timeout register, the firmware will reset that mailbox.
Event notifications are sent from the firmware to the host. The host tells the
firmware which events it is interested in via an API call. That call tells the
firmware which notification mailbox to use. The firmware signals the host via
an interrupt. Only the 16 Results fields are used, the Flags, Command, Return
value and Timeout words are not used.

This page describes the structures and procedures used by the cx2341x DMA
engine.
Introduction
============
The cx2341x PCI interface is busmaster capable. This means it has a DMA
engine to efficiently transfer large volumes of data between the card and main
memory without requiring help from a CPU. Like most hardware, it must operate
on contiguous physical memory. This is difficult to come by in large quantities
on virtual memory machines.
Therefore, it also supports a technique called "scatter-gather". The card can
transfer multiple buffers in one operation. Instead of allocating one large
contiguous buffer, the driver can allocate several smaller buffers.
In practice, I've seen the average transfer to be roughly 80K, but transfers
above 128K were not uncommon, particularly at startup. The 128K figure is
important, because that is the largest block that the kernel can normally
allocate. Even still, 128K blocks are hard to come by, so the driver writer is
urged to choose a smaller block size and learn the scatter-gather technique.
Mailbox #10 is reserved for DMA transfer information.
Flow
====
This section describes, in general, the order of events when handling DMA
transfers. Detailed information follows this section.
- The card raises the Encoder interrupt.
- The driver reads the transfer type, offset and size from Mailbox #10.
- The driver constructs the scatter-gather array from enough free dma buffers
to cover the size.
- The driver schedules the DMA transfer via the ScheduleDMAtoHost API call.
- The card raises the DMA Complete interrupt.
- The driver checks the DMA status register for any errors.
- The driver post-processes the newly transferred buffers.
NOTE! It is possible that the Encoder and DMA Complete interrupts get raised
simultaneously. (End of the last, start of the next, etc.)
Mailbox #10
===========
The Flags, Command, Return Value and Timeout fields are ignored.
Name: Mailbox #10
Results[0]: Type: 0: MPEG.
Results[1]: Offset: The position relative to the card's memory space.
Results[2]: Size: The exact number of bytes to transfer.
My speculation is that since the StartCapture API has a capture type of "RAW"
available, that the type field will have other values that correspond to YUV
and PCM data.
Scatter-Gather Array
====================
The scatter-gather array is a contiguously allocated block of memory that
tells the card the source and destination of each data-block to transfer.
Card "addresses" are derived from the offset supplied by Mailbox #10. Host
addresses are the physical memory location of the target DMA buffer.
Each S-G array element is a struct of three 32-bit words. The first word is
the source address, the second is the destination address. Both take up the
entire 32 bits. The lowest 16 bits of the third word is the transfer byte
count. The high-bit of the third word is the "last" flag. The last-flag tells
the card to raise the DMA_DONE interrupt. From hard personal experience, if
you forget to set this bit, the card will still "work" but the stream will
most likely get corrupted.
The transfer count must be a multiple of 256. Therefore, the driver will need
to track how much data in the target buffer is valid and deal with it
accordingly.
Array Element:
- 32-bit Source Address
- 32-bit Destination Address
- 16-bit reserved (high bit is the last flag)
- 16-bit byte count
DMA Transfer Status
===================
Register 0x0004 holds the DMA Transfer Status:
Bit
4 Scatter-Gather array error
3 DMA write error
2 DMA read error
1 write completed
0 read completed

This document describes the cx2341x memory map and documents some of the register
space.
Warning! This information was figured out from searching through the memory and
registers, this information may not be correct and is certainly not complete, and
was not derived from anything more than searching through the memory space with
commands like:
ivtvctl -O min=0x02000000,max=0x020000ff
So take this as is, I'm always searching for more stuff, it's a large
register space :-).
Memory Map
==========
The cx2341x exposes its entire 64M memory space to the PCI host via the PCI BAR0
(Base Address Register 0). The addresses here are offsets relative to the
address held in BAR0.
0x00000000-0x00ffffff Encoder memory space
0x00000000-0x0003ffff Encode.rom
???-??? MPEG buffer(s)
???-??? Raw video capture buffer(s)
???-??? Raw audio capture buffer(s)
???-??? Display buffers (6 or 9)
0x01000000-0x01ffffff Decoder memory space
0x01000000-0x0103ffff Decode.rom

0x0114b000-0x0115afff Audio.rom (deprecated?)
0x02000000-0x0200ffff Register Space
Registers
=========
The registers occupy the 64k space starting at the 0x02000000 offset from BAR0.
All of these registers are 32 bits wide.
DMA Registers 0x000-0xff:
0x00 - Control:
0=reset/cancel, 1=read, 2=write, 4=stop
0x04 - DMA status:
1=read busy, 2=write busy, 4=read error, 8=write error, 16=link list error
0x08 - pci DMA pointer for read link list
0x0c - pci DMA pointer for write link list
0x10 - read/write DMA enable:
1=read enable, 2=write enable
0x14 - always 0xffffffff, if set any lower instability occurs, 0x00 crashes
0x18 - ??
0x1c - always 0x20 or 32, smaller values slow down DMA transactions
0x20 - always value of 0x780a010a
0x24-0x3c - usually just random values???
0x40 - Interrupt status
0x44 - Write a bit here and shows up in Interrupt status 0x40
0x48 - Interrupt Mask
0x4C - always value of 0xfffdffff,
if changed to 0xffffffff DMA write interrupts break.
0x50 - always 0xffffffff
0x54 - always 0xffffffff (0x4c, 0x50, 0x54 seem like interrupt masks, are
3 processors on chip, Java ones, VPU, SPU, APU, maybe these are the
interrupt masks???).
0x60-0x7C - random values
0x80 - first write linked list reg, for Encoder Memory addr
0x84 - first write linked list reg, for pci memory addr
0x88 - first write linked list reg, for length of buffer in memory addr
(|0x80000000 or this for last link)
0x8c-0xcc - rest of write linked list reg, 8 sets of 3 total, DMA goes here
from linked list addr in reg 0x0c, firmware must push through or
something.
0xe0 - first (and only) read linked list reg, for pci memory addr
0xe4 - first (and only) read linked list reg, for Decoder memory addr
0xe8 - first (and only) read linked list reg, for length of buffer
0xec-0xff - Nothing seems to be in these registers, 0xec-f4 are 0x00000000.
Memory locations for Encoder Buffers 0x700-0x7ff:
These registers show offsets of memory locations pertaining to each
buffer area used for encoding, have to shift them by <<1 first.

- Write 0x80000640 to register 0x08F8 to init the Decoder SDRAM's refresh to 1us.
- Sleep for 512ms. (600ms is recommended)
- Transfer the encoder's firmware image to offset 0 in Encoder memory space.
- Transfer the decoder's firmware image to offset 0 in Decoder memory space.
- Use a read-modify-write operation to Clear bit 0 of register 0x9050 to
re-enable the SPU.
- Sleep for 1 second.
- Use a read-modify-write operation to Clear bits 3 and 0 of register 0x9058
to re-enable the VPU.
- Sleep for 1 second.

The controls for the mux are GPIO [0,1] for source, and GPIO 2 for muting.
GPIO0 GPIO1
0 0 TV Audio
1 0 FM radio
0 1 Line-In
1 1 Mono tuner bypass or CD passthru (tuner specific)
GPIO 16(i believe) is tied to the IR port (if present).

>From the data sheet:
Register 24'h20004 PCI Interrupt Status
bit [18] IR_SMP_INT Set when 32 input samples have been collected over
gpio[16] pin into GP_SAMPLE register.
What's missing from the data sheet:
Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
compat remote)
set register 0x35C050 to 0xa80a80
enable sampling
set register 0x35C054 to 0x5
Of course, enable the IRQ bit 18 in the interrupt mask register .(and
provide for a handler)
GP_SAMPLE register is at 0x35C058
Bits are then right shifted into the GP_SAMPLE register at the specified
rate; you get an interrupt when a full DWORD is recieved.
You need to recover the actual RC5 bits out of the (oversampled) IR sensor
bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data) An
actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
I'm pretty sure when no IR signal is present the receiver is always in a
marking state(1); but stray light, etc can cause intermittent noise values
as well. Remember, this is a free running sample of the IR receiver state
over time, so don't assume any sample starts at any particular place.
http://www.atmel.com/dyn/resources/prod_documents/doc2817.pdf
This data sheet (google search) seems to have a lovely description of the
RC5 basics
http://users.pandora.be/nenya/electronics/rc5/ and more data
http://www.ee.washington.edu/circuit_archive/text/ir_decode.txt
and even a reference to how to decode a bi-phase data stream.

framerate This setting controls frame rate of the camera. This is
an approximate setting (in terms of "worst" ... "best")
because camera changes frame rate depending on amount
of light available. Setting 0 is slowest, 6 is fastest.
Beware - fast settings are very demanding and may not
work well with all video sizes. Be conservative.

hue_correction This highly optional setting allows to adjust the
hue of the image in a way slightly different from
what usual "hue" control does. Both controls affect
YUV colorspace: regular "hue" control adjusts only
U component, and this "hue_correction" option similarly
adjusts only V component. However usually it is enough
to tweak only U or V to compensate for colored light or
color temperature; this option simply allows more
complicated correction when and if it is necessary.

size This setting chooses one of several image sizes that are
supported by this driver. Cameras may support more, but
it's difficult to reverse-engineer all formats.
Following video sizes are supported:
size=0 128x96 (Model 1 only)
size=1 160x120
size=2 176x144
size=3 320x240 (Model 2 only)
size=4 352x240 (Model 2 only)
size=5 352x288
size=6 640x480 (Model 3 only)
The 352x288 is the native size of the Model 1 sensor
array, so it's the best resolution the camera can
yield. The best resolution of Model 2 is 176x144, and
larger images are produced by stretching the bitmap.
Model 3 has sensor with 640x480 grid, and it works too,
but the frame rate will be exceptionally low (1-2 FPS);
it may be still OK for some applications, like security.
Choose the image size you need. The smaller image can
support faster frame rate. Default is 352x288.
