[DVB patch 00/37] DVB updates for 2.6.12-rc4

[DVB patch 00/37] DVB updates for 2.6.12-rc4

[Johannes Stezenbach]

Hi Andrew,

here are a bunch of patches from linuxtv.org CVS. Nothing
exciting, just bugfixes, cleanups and support for a number
of new card variants.

One hunk from my previous patchset didn't make it into
2.6.12-rc4, but still lingers somewhere in rc3-mm3,
thus the "make dvb_class static" patch will be rejected
when applying to -rc3-mm3:
dvb-core/dvbdev.c from http://lkml.org/lkml/2005/3/21/321

Please apply.

Thanks,
Johannes

 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
-
-For Pinnacle PCTV cards use the "cx24110" frontend driver:
-   $ modprobe cx24110
+   $ 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 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
+
+#define CA_RESET          _IO('o', 128)
+#define CA_GET_CAP        _IOR('o', 129, ca_caps_t)
+#define CA_GET_SLOT_INFO  _IOR('o', 130, ca_slot_info_t)
+#define CA_GET_DESCR_INFO _IOR('o', 131, ca_descr_info_t)
+#define CA_GET_MSG        _IOR('o', 132, ca_msg_t)
+#define CA_SEND_MSG       _IOW('o', 133, ca_msg_t)
+#define CA_SET_DESCR      _IOW('o', 134, ca_descr_t)
+#define CA_SET_PID        _IOW('o', 135, ca_pid_t)
+
+
+On querying the device, the device yields information thus
+
+CA_GET_SLOT_INFO
+----------------------------
+Command = [info]
+APP: Number=[1]
+APP: Type=[1]
+APP: flags=[1]
+APP: CI High level interface
+APP: CA/CI Module Present
+
+CA_GET_CAP
+----------------------------
+Command = [caps]
+APP: Slots=[1]
+APP: Type=[1]
+APP: Descrambler keys=[16]
+APP: Type=[1]
+
+CA_SEND_MSG
+----------------------------
+Descriptors(Program Level)=[ 09 06 06 04 05 50 ff f1]
+Found CA descriptor @ program level
+
+(20) ES type=[2] ES pid=[201]  ES length =[0 (0x0)]
+(25) ES type=[4] ES pid=[301]  ES length =[0 (0x0)]
+ca_message length is 25 (0x19) bytes
+EN50221 CA MSG=[ 9f 80 32 19 03 01 2d d1 f0 08 01 09 06 06 04 05 50 ff f1 02 e0 c9 00 00 04 e1 2d 00 00]
+
+
+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.
+
+
+/* a message to/from a CI-CAM */
+typedef struct ca_msg {
+	unsigned int index;
+	unsigned int type;
+	unsigned int length;
+	unsigned char msg[256];
+} ca_msg_t;
+
+
+The flow of data can be described thus,
+
+
+
+
+
+	App (User)
+	-----
+	parse
+	  |
+	  |
+	  v
+	en50221 APDU (package)
+   --------------------------------------

+
+
+
+
+The High Level CI interface uses the EN50221 DVB standard, following a
+standard ensures futureproofness.

[DVB patch 37/37] budget-av: CI fixes

[Johannes Stezenbach]

[-- Attachment #1: dvb-ttpci-budget-ca.patch --]
[-- Type: text/plain, Size: 12993 bytes --]

- remove enable_ci, ci interface is assumed to be present if the saa7113
  is not found.
- reduce the delay when checking for saa7113
- clean up the cam reset according to specifications
- turn off Vcc to the cam slot if cam is removed or fails reset
- remove cam reset in ciintf_init
- clean up printks (KERN_)
- move gpio setting into saa7113_init
- clean up unreadable frontend_init
(Kenneth Aafloy)

Do you view this as 2.6.12 material?

Yes, that fix seems to have been made upstream somewhere, so I'll drop that
patch.

I notice that Greg's tree changes dvb_class to be of type class_simple, so
there may be interactions between your stuff and
gregkh-01-driver-gregkh-driver-022_class-11-drivers.patch.  We'll see. 
(Warning, Greg's patch names tend to change, but it'll be something like
that).

I notice you have a lot of things like:

  Switch analog output of the Crystal sound chip to left/stereo/right mode.
  This will fix problems with some (most?) channels which do not encode 2-channel
  audio correctly. (Oliver Endriss)

In future, please try to gather Signed-off-by: lines for these
contributions, thanks.

Yes, all of it is well tested and has been in CVS for a while.

OK, I'll check that.

How should we handle this with CVS? Should people add a
Signed-off-by: line to the CVS commit log? If they don't,
can I assume that "by policy" the Signed-off-by: line for
the committer is implicit? Or do I have to bug them to
mail me the Signed-off-by: line?


Thanks,
Johannes

That sounds reasonable.

I wouldn't do that.  S-O-B does imply that they have read, agreed to and
complied with the "Developer's Certificate of Origin" from
Documentation/SubmittingPatches.  That is not a thing which person A should
be asserting on person B's behalf.

Yes please.
