Hello Linus, Andrew,
I'm about to send you a set of 5 patches that sync the
LinuxTV.org CVS with latest linux-2.6.1/linux-2.6.1-mm4.
As usual, detailed informations about what changed can be
found at the top of each file.
The patch "04-DVB-av7110-driver-splitup.diff" is bzip2'ed,
because it removes the av7110 DVB driver source and replaces
it with a modularized version. Sorry for the inconvenience!
Please apply!
CU
Michael.

Getting the Firmware
--------------------
-Currently, the driver only works with v2.15a of the firmware. The firmwares
-can be obtained in this way:
+The firmware can be found in the software update zip files on this page:
+http://www.hauppauge.de/sw_dec.htm
-wget http://hauppauge.lightpath.net/de/dec215a.exe
-unzip -j dec215a.exe Software/Oem/STB/App/Boot/STB_PC_T.bin
-unzip -j dec215a.exe Software/Oem/STB/App/Boot/STB_PC_S.bin
+The firmwares are named as follows:
+DEC2000-t: STB_PC_T.bin
+DEC2540-t: STB_PC_X.bin
+DEC3000-s: STB_PC_S.bin
+
+Note that firmwares since version 2.16 beta2 for the DEC2000-t give the device
+the USB ID of the DEC3000-s. The driver copes with this.
+
+Instructions follow for retrieving version 2.16 of the firmware:
+
+wget http://hauppauge.lightpath.net/de/dec216.exe
+unzip -j dec216.exe software/OEM/STB/App/Boot/STB_PC_T.bin

Compilation Notes for 2.4 kernels
---------------------------------
For 2.4 kernels the firmware for the DECs is compiled into the driver itself.
-The firmwares are expected to be in /etc/dvb at compilation time.

- [DVB] after the firmware removal, split av7110.c into separate modules:
- av7110.c: initialization and demux stuff
- av7110_hw.c: lowlevel hardware access and firmware interface
- av7110_ca.c: CI and ECD
- av7110_av.c: audio/video MPEG decoder and remuxing stuff
- av7110_v4l.c: v4l interface
- [DVB] av7110 fixes that were notcies during splitup
- rename some non-static functions to enhance readability
- lots of coding style & whitespace fixes
- return -ERESTARTSYS from ci_ll_read/write() if interrupted
- use time_after() for timeouts
- added some comments about firmware interface
- removed some unused fields from struct av7110, retabbing
- [DVB] follow driver splitup in Makefile
- [DVB] fix memory leak in page table handling
- [DVB] minor coding style changes
- [DVB] add simple resource management for video dmas (borrowed from saa7134)
- [DVB] use resource management to lock video and vbi access which sometimes share the same video dmas
- [DVB] honour return codes of extension functions in various places, when resources could not be locked
- [DVB] remove remains of dead code which were commented out anyway
- [DVB] add new flag FORMAT_IS_PLANAR to indicate planar capture formats, needed for resource allocation

- [DVB] TTUSB-DEC update by Alex Woods:
- fix USB timeout bug under 2.6
- change some variable names to make it clearer what we are dealing with (PVA).
- support DEC2540-t and add info on it to the ttusb-dec docs.
- add model number returned from DEC2540-t firmware.
- add a module option to get the raw AVPES packets from the dvr device.
- send audio packets to their filter rather than the videos.
- handle the new empty packets that appear with the 2.16 firmware.
- extra error checks.
- handle the new firmwares that change the devices' USB IDs.
- tidy up the STB initialisation process a little.
- apply Hans-Frieder Vogt's patch for calculating firmware CRCs.
- [DVB] make TTUSB budget card depend on USB subsystem

- schedule_timeout(1) in dvb_frontend.c after setting frontend and before waking up frontend thread
- do FE_RESET in each iteration of frontend thread if !FE_HAS_LOCK
- use aquire_signal flag to call FE_RESET only after tuning until FE_HAS_LOCK has been signalled, and not when FE_HAS_LOCK drops out for short periods of time later
