+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)
+
+Testing changes

+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

+* 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

+
+
+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.
+
+

+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,

+When:	November 2005
+Files:	drivers/ieee1394/{amdtp,cmp}*

-Driver Detach Power Management
-
-The kernel now supports the ability to place a device in a low-power
-state when it is detached from its driver, which happens when its
-module is removed. 
-
-Each device contains a 'detach_state' file in its sysfs directory
-which can be used to control this state. Reading from this file
-displays what the current detach state is set to. This is 0 (On) by
-default. A user may write a positive integer value to this file in the
-range of 1-4 inclusive. 
-
-A value of 1-3 will indicate the device should be placed in that
-low-power state, which will cause ->suspend() to be called for that
-device. A value of 4 indicates that the device should be shutdown, so
-->shutdown() will be called for that device. 
-
-The driver is responsible for reinitializing the device when the
-module is re-inserted during it's ->probe() (or equivalent) method. 
-The driver core will not call any extra functions when binding the
-device to the driver.

- * 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]
