-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
-
-Acknowledgements (just for the rewriting part)
-================
-
-Bjarne Steinsbo thought a lot in the first place of the pci part for this code
-sharing idea.

+video buffer helper functions
+-----------------------------
+
+The v4l2 core API provides a standard method for dealing with video
+buffers. Those methods allow a driver to implement read(), mmap() and
+overlay() on a consistent way.
+
+There are currently methods for using video buffers on devices that
+supports DMA with scatter/gather method (videobuf-dma-sg), DMA with
+linear access (videobuf-dma-contig), and vmalloced buffers, mostly
+used on USB drivers (videobuf-vmalloc).
+
+Any driver using videobuf should provide operations (callbacks) for
+four handlers:
+
+ops->buf_setup   - calculates the size of the video buffers and avoid they
+		   to waste more than some maximum limit of RAM;
+ops->buf_prepare - fills the video buffer structs and calls
+		   videobuf_iolock() to alloc and prepare mmaped memory;
+ops->buf_queue   - advices the driver that another buffer were
+		   requested (by read() or by QBUF);
+ops->buf_release - frees any buffer that were allocated.
+
+In order to use it, the driver need to have a code (generally called at
+interrupt context) that will properly handle the buffer request lists,
+announcing that a new buffer were filled.
+
+The irq handling code should handle the videobuf task lists, in order
+to advice videobuf that a new frame were filled, in order to honor to a
+request. The code is generally like this one:
+	if (list_empty(&dma_q->active))
+		return;
+
+	buf = list_entry(dma_q->active.next, struct vbuffer, vb.queue);
+
+	if (!waitqueue_active(&buf->vb.done))
+		return;
+
+	/* Some logic to handle the buf may be needed here */
+
+	list_del(&buf->vb.queue);
+	do_gettimeofday(&buf->vb.ts);
+	wake_up(&buf->vb.done);
+
+Those are the videobuffer functions used on drivers, implemented on
+videobuf-core:
+
+- Videobuf init functions
+  videobuf_queue_sg_init()
+      Initializes the videobuf infrastructure. This function should be
+      called before any other videobuf function on drivers that uses DMA
+      Scatter/Gather buffers.
+
+  videobuf_queue_dma_contig_init
+      Initializes the videobuf infrastructure. This function should be
+      called before any other videobuf function on drivers that need DMA
+      contiguous buffers.
+
+  videobuf_queue_vmalloc_init()
+      Initializes the videobuf infrastructure. This function should be
+      called before any other videobuf function on USB (and other drivers)
+      that need a vmalloced type of videobuf.
+
+- videobuf_iolock()
+  Prepares the videobuf memory for the proper method (read, mmap, overlay).
+
+- videobuf_queue_is_busy()
+  Checks if a videobuf is streaming.
+
+- videobuf_queue_cancel()
+  Stops video handling.
+
+- videobuf_mmap_free()
+  frees mmap buffers.
+
+- videobuf_stop()
+  Stops video handling, ends mmap and frees mmap and other buffers.
+
+- V4L2 api functions. Those functions correspond to VIDIOC_foo ioctls:
+   videobuf_reqbufs(), videobuf_querybuf(), videobuf_qbuf(),
+   videobuf_dqbuf(), videobuf_streamon(), videobuf_streamoff().
+
+- V4L1 api function (corresponds to VIDIOCMBUF ioctl):
+   videobuf_cgmbuf()
+      This function is used to provide backward compatibility with V4L1
+      API.
+
+- Some help functions for read()/poll() operations:
+   videobuf_read_stream()
+      For continuous stream read()
+   videobuf_read_one()
+      For snapshot read()
+   videobuf_poll_stream()
+      polling help function
+
+The better way to understand it is to take a look at vivi driver. One
+of the main reasons for vivi is to be a videobuf usage example. the
+vivi_thread_tick() does the task that the IRQ callback would do on PCI
+drivers (or the irq callback on USB).
