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
|
||||
DVB-stuff: can be written for common use

2) Loading Modules
|
||||
==================
|
||||
|
||||
In general you need to load the bttv driver, which will handle the gpio and
|
||||
i2c communication for us. Next you need the common dvb-bt8xx device driver
|
||||
and one frontend driver.
|
||||
|
||||
The bttv driver will HANG YOUR SYSTEM IF YOU DO NOT SPECIFY THE CORRECT
|
||||
CARD ID!
|
||||
|
||||
(If you don't get your card running and you suspect that the card id you're
|
||||
using is wrong, have a look at "bttv-cards.c" for a list of possible card
|
||||
ids.)
|
||||
|
||||
Pay attention to failures when you load the frontend drivers
|
||||
(e.g. dmesg, /var/log/messages).
|
||||
i2c communication for us, plus the common dvb-bt8xx device driver.
|
||||
The frontends for Nebula (nxt6000), Pinnacle PCTV (cx24110) and
|
||||
TwinHan (dst) are loaded automatically by the dvb-bt8xx device driver.
|
||||
|
||||
3a) Nebula / Pinnacle PCTV
|
||||
--------------------------
|
||||
|
||||
$ modprobe bttv i2c_hw=1 card=0x68
|
||||
$ modprobe dvb-bt8xx
|
||||
|
||||
For Nebula cards use the "nxt6000" frontend driver:
|
||||
$ modprobe nxt6000
|
||||
$ modprobe bttv (normally bttv is being loaded automatically by kmod)
|
||||
$ modprobe dvb-bt8xx (or just place dvb-bt8xx in /etc/modules for automatic loading)
|
||||
|
||||
For Pinnacle PCTV cards use the "cx24110" frontend driver:
|
||||
$ modprobe cx24110
|
||||
|
||||
3b) TwinHan
|
||||
-----------
|
||||
3b) TwinHan and Clones
|
||||
--------------------------
|
||||
|
||||
$ modprobe bttv i2c_hw=1 card=0x71
|
||||
$ modprobe dvb-bt8xx
|
||||
$ modprobe dst
|
||||
|
||||
The value 0x71 will override the PCI type detection for dvb-bt8xx, which
|
||||
is necessary for TwinHan cards.#

||||
The value 0x71 will override the PCI type detection for dvb-bt8xx,
|
||||
which is necessary for TwinHan cards.
|
||||
|
||||
If you're having an older card (blue color circuit) and card=0x71 locks your
|
||||
machine, try using 0x68, too. If that does not work, ask on the DVB mailing list.

The DST module takes a couple of useful parameters, in case the
|
||||
dst drivers fails to detect your type of card correctly.
|
||||
The DST module takes a couple of useful parameters.
|
||||
|
||||
dst_type takes values 0 (satellite), 1 (terrestial TV), 2 (cable).
|
||||
verbose takes values 0 to 5. These values control the verbosity level.
|
||||
|
||||
dst_type_flags takes bit combined values:
|
||||
1 = new tuner type packets. You can use this if your card is detected
|
||||
and you have debug and you continually see the tuner packets not
|
||||
working (make sure not a basic problem like dish alignment etc.)
|
||||
debug takes values 0 and 1. You can either disable or enable debugging.
|
||||
|
||||
2 = TS 204. If your card tunes OK, but the picture is terrible, seemingly
|
||||
breaking up in one half continually, and crc fails a lot, then
|
||||
this is worth a try (or trying to turn off)
|
||||
dst_addons takes values 0 and 0x20. A value of 0 means it is a FTA card.
|
||||
0x20 means it has a Conditional Access slot.
|
||||
|
||||
4 = has symdiv. Some cards, mostly without new tuner packets, require
|
||||
a symbol division algorithm. Doesn't apply to terrestial TV.
|
||||
|
||||
You can also specify a value to have the autodetected values turned off
|
||||
(e.g. 0). The autodected values are determined bythe cards 'response
|
||||
The autodected values are determined bythe cards 'response
|

||||
dst_get_device_id: Recognise [DSTMCI]

* For the user
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
NOTE: This document describes the usage of the high level CI API as
|
||||
in accordance to the Linux DVB API. This is a not a documentation for the,
|
||||
existing low level CI API.
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
To utilize the High Level CI capabilities,
|
||||
|
||||
(1*) This point is valid only for the Twinhan/clones
|
||||
For the Twinhan/Twinhan clones, the dst_ca module handles the CI
|
||||
hardware handling.This module is loaded automatically if a CI
|
||||
(Common Interface, that holds the CAM (Conditional Access Module)
|
||||
is detected.
|
||||
|
||||
(2) one requires a userspace application, ca_zap. This small userland
|
||||
application is in charge of sending the descrambling related information
|
||||
to the CAM.
|
||||
|
||||
This application requires the following to function properly as of now.
|
||||
|
||||
(a) Tune to a valid channel, with szap.
|
||||
eg: $ szap -c channels.conf -r "TMC" -x
|
||||
|
||||
(b) a channels.conf containing a valid PMT PID
|
||||
|
||||
eg: TMC:11996:h:0:27500:278:512:650:321
|
||||
|
||||
here 278 is a valid PMT PID. the rest of the values are the
|
||||
same ones that szap uses.
|
||||
|
||||
(c) after running a szap, you have to run ca_zap, for the
|
||||
descrambler to function,
|
||||
|
||||
eg: $ ca_zap patched_channels.conf "TMC"
|
||||
|
||||
The patched means a patch to apply to scan, such that scan can
|
||||
generate a channels.conf_with pmt, which has this PMT PID info
|
||||
(NOTE: szap cannot use this channels.conf with the PMT_PID)
|
||||
|
||||
|
||||
(d) Hopeflly Enjoy your favourite subscribed channel as you do with
|
||||
a FTA card.
|
||||
|
||||
(3) Currently ca_zap, and dst_test, both are meant for demonstration
|
||||
purposes only, they can become full fledged applications if necessary.
|
||||
|
||||
|
||||
* Cards that fall in this category
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
At present the cards that fall in this category are the Twinhan and it's
|
||||
clones, these cards are available as VVMER, Tomato, Hercules, Orange and
|
||||
so on.
|
||||
|
||||
* CI modules that are supported
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
The CI module support is largely dependant upon the firmware on the cards
|
||||
Some cards do support almost all of the available CI modules. There is
|
||||
nothing much that can be done in order to make additional CI modules
|
||||
working with these cards.
|
||||
|
||||
Modules that have been tested by this driver at present are
|
||||
|
||||
(1) Irdeto 1 and 2 from SCM
|
||||
(2) Viaccess from SCM
|
||||
(3) Dragoncam
|
||||
|
||||
* The High level CI API
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
* For the programmer
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
With the High Level CI approach any new card with almost any random
|
||||
architecture can be implemented with this style, the definitions
|
||||
insidethe switch statement can be easily adapted for any card, thereby
|
||||
eliminating the need for any additional ioctls.
|
||||
|
||||
The disadvantage is that the driver/hardware has to manage the rest. For
|
||||
the application programmer it would be as simple as sending/receiving an
|
||||
array to/from the CI ioctls as defined in the Linux DVB API. No changes
|
||||
have been made in the API to accomodate this feature.
|
||||
|
||||
|
||||
* Why the need for another CI interface ?
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
This is one of the most commonly asked question. Well a nice question.
|
||||
Strictly speaking this is not a new interface.
|
||||
|
||||
The CI interface is defined in the DVB API in ca.h as
|
||||
|
||||
typedef struct ca_slot_info {
|
||||
int num; /* slot number */
|
||||
|
||||
int type; /* CA interface this slot supports */
|
||||
#define CA_CI 1 /* CI high level interface */
|
||||
#define CA_CI_LINK 2 /* CI link layer level interface */
|
||||
#define CA_CI_PHYS 4 /* CI physical layer level interface */
|
||||
#define CA_DESCR 8 /* built-in descrambler */
|
||||
#define CA_SC 128 /* simple smart card interface */
|
||||
|
||||
unsigned int flags;
|
||||
#define CA_CI_MODULE_PRESENT 1 /* module (or card) inserted */
|
||||
#define CA_CI_MODULE_READY 2
|
||||
} ca_slot_info_t;
|
||||
|
||||
|
||||
|
||||
This CI interface follows the CI high level interface, which is not
|
||||
implemented by most applications. Hence this area is revisited.
|
||||
|
||||
This CI interface is quite different in the case that it tries to
|
||||
accomodate all other CI based devices, that fall into the other categories
|
||||
|
||||
This means that this CI interface handles the EN50221 style tags in the
|
||||
Application layer only and no session management is taken care of by the
|
||||
application. The driver/hardware will take care of all that.
|
||||
|
||||
This interface is purely an EN50221 interface exchanging APDU's. This
|
||||
means that no session management, link layer or a transport layer do
|
||||
exist in this case in the application to driver communication. It is
|
||||
as simple as that. The driver/hardware has to take care of that.
|
||||
|
||||
|
||||
With this High Level CI interface, the interface can be defined with the
|
||||
regular ioctls.
|
||||
|
||||
All these ioctls are also valid for the High level CI interface
|
||||

Not all ioctl's are implemented in the driver from the API, the other
|
||||
features of the hardware that cannot be implemented by the API are achieved
|
||||
using the CA_GET_MSG and CA_SEND_MSG ioctls. An EN50221 style wrapper is
|
||||
used to exchange the data to maintain compatibility with other hardware.

Support the ACPI PM timer for time keeping. This is slow,

but is useful on some chipsets without HPET on systems with more
|
||||
than one CPU. On a single processor or single socket multi core
|
||||
system it is normally not required.
|

When the PM timer is active 64bit vsyscalls are disabled
|
||||
and should not be enabled (/proc/sys/kernel/vsyscall64 should
|
||||
not be changed).
|

The kernel selects the PM timer only as a last resort, so it is

useful to enable just in case.

* Synchronize TSCs of CPUs
|

* New Funky TSC sync algorithm borrowed from IA64.
|
||||
* Main advantage is that it doesn't reset the TSCs fully and
|
||||
* in general looks more robust and it works better than my earlier
|
||||
* attempts. I believe it was written by David Mosberger. Some minor
|
||||
* adjustments for x86-64 by me -AK
|
||||
*
|
||||
* This new algorithm is less accurate than the old "zero TSCs"
|
||||
* one, but we cannot zero TSCs anymore in the new hotplug CPU
|
||||
* model.
|
||||
* Original comment reproduced below.
|
||||
*
|
||||
* Synchronize TSC of the current (slave) CPU with the TSC of the
|
||||
* MASTER CPU (normally the time-keeper CPU). We use a closed loop to
|
||||
* eliminate the possibility of unaccounted-for errors (such as
|
||||
* getting a machine check in the middle of a calibration step). The
|
||||
* basic idea is for the slave to ask the master what itc value it has
|
||||
* and to read its own itc before and after the master responds. Each
|
||||
* iteration gives us three timestamps:
|
||||
*
|
||||
* slave master
|
||||
*
|
||||
* t0 ---\
|
||||
* ---\
|
||||
* --->
|
||||
* tm
|
||||
* /---
|
||||
* /---
|
||||
* t1 <---
|
||||
*
|
||||
*
|
||||
* The goal is to adjust the slave's TSC such that tm falls exactly
|
||||
* half-way between t0 and t1. If we achieve this, the clocks are
|
||||
* synchronized provided the interconnect between the slave and the
|
||||
* master is symmetric. Even if the interconnect were asymmetric, we
|
||||
* would still know that the synchronization error is smaller than the
|
||||
* roundtrip latency (t0 - t1).
|
||||
*
|
||||
* When the interconnect is quiet and symmetric, this lets us
|
||||
* synchronize the TSC to within one or two cycles. However, we can
|
||||
* only *guarantee* that the synchronization is accurate to within a
|
||||
* round-trip time, which is typically in the range of several hundred
|
||||
* cycles (e.g., ~500 cycles). In practice, this means that the TSCs
|
||||
* are usually almost perfectly synchronized, but we shouldn't assume
|
||||
* that the accuracy is much better than half a micro second or so.
|
||||
*
|
||||
* [there are other errors like the latency of RDTSC and of the
|
||||
* WRMSR. These can also account to hundreds of cycles. So it's
|
||||
* probably worse. It claims 153 cycles error on a dual Opteron,
|
||||
* but I suspect the numbers are actually somewhat worse -AK]
