in his system. I changed the setting of
INT_MASK for CAP_CONTINUOUS to be exactly
the same as CAP_SINGLE apparently setting
bit 23 cleared the system lock up.
version 1.1 of the driver has been reported
to work with STB's WinTv, Hauppage's Wincast/Tv
and last but not least with the Intel Smart
Video Recorder.

1.18 4/23/97 Clean up after failed CAP_SINGLEs where bt
interrupt isn't delivered, and fixed fixing
CAP_SINGLEs that for ODD_ONLY fields.
1.19 9/8/97 improved yuv support , cleaned up weurope
channel table, incorporated cleanup work from
Luigi, fixed pci interface bug due to a
change in the pci interface which disables

submitted code to support radio available with in
some bt848 based cards;additionally, wrote code to
correctly recognized his bt848 card.
Roger Hardiman <roger@cs.strath.ac.uk> submitted
various fixes to smooth out the microcode and made
all modes consistent.
1.26 Moved Luigi's I2CWR ioctl from the video_ioctl
section to the tuner_ioctl section
Changed Major device from 79 to 92 and reserved
our Major device number -- hasty@star-gate.com
1.27 Last batch of patches for radio support from
Flemming Jacobsen <fj@trw.nl>.
Added B849 PCI ID submitted by:
Tomi Vainio <tomppa@fidata.fi>
1.28 Frank Nobis <fn@Radio-do.de> added tuner support
for the German Phillips PAL tuner and
additional channels for german cable tv.
1.29 Roger Hardiman <roger@cs.strath.ac.uk>
Revised autodetection code to correctly handle both
old and new VideoLogic Captivator PCI cards.
Added tsleep of 2 seconds to initialistion code
for PAL users.Corrected clock selection code on
format change.
1.30 Bring back Frank Nobis <fn@Radio-do.de>'s opt_bktr.h
1.31 Randall Hopper <rhh@ct.picker.com>
submitted ioctl to clear the video buffer
prior to starting video capture
Amancio : clean up yuv12 so that it does not
affect rgb capture. Basically, fxtv after
capturing in yuv12 mode , switching to rgb
would cause the video capture to be too bright.
1.32 disable inverse gamma function for rgb and yuv
capture. fixed meteor brightness ioctl it now
converts the brightness value from unsigned to
signed.
1.33 added sysctl: hw.bt848.tuner, hw.bt848.reverse_mute,
hw.bt848.card
card takes a value from 0 to bt848_max_card
tuner takes a value from 0 to bt848_max_tuner
reverse_mute : 0 no effect, 1 reverse tuner
mute function some tuners are wired reversed :(
1.34 reverse mute function for ims turbo card
1.35 Roger Hardiman <roger@cs.strath.ac.uk>
options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL
in the kernel config file makes the driver's
video_open() function select PAL rather than NTSC.
This fixed all the hangs on my Dual Crystal card
when using a PAL video signal. As a result, you
can loose the tsleep (of 2 seconds - now 0.25!!)
which I previously added. (Unless someone else
wanted the 0.25 second tsleep).
1.36 added bt848.format sysctl variable.
1 denotes NTSC , 0 denotes PAL
1.37 added support for Bt878 and improved Hauppauge's
bt848 tuner recognition
1.38 Further improvements on Hauppauge's rely on
eeprom[9] to determine the tuner type 8)
AVerMedia card type added <sos@freebsd.org>
1.39 08/05/98 Roger Hardiman <roger@cs.strath.ac.uk>
Updated Hauppauge detection code for Tuner ID 0x0a
for newer NTSC WinCastTV 404 with Bt878 chipset.
Tidied up PAL default in video_open()
Soren bumped version from 1.39 to 1.49 to sync
with FreeBSD CVS numbers.
1.49 10 August 1998 Roger Hardiman <roger@cs.strath.ac.uk>
Added Capture Area ioctl - BT848[SG]CAPAREA.
Normally the full 640x480 (768x576 PAL) image
is grabbed. This ioctl allows a smaller area
from anywhere within the video image to be
grabbed, eg a 400x300 image from (50,10).
See restrictions in BT848SCAPAREA.
1.50 31 August 1998 Roger Hardiman <roger@cs.strath.ac.uk>
Renamed BT848[SG]CAPAREA to BT848_[SG]CAPAREA.
Added PR kern/7177 for SECAM Video Highway Xtreme
with single crystal PLL configuration
submitted by Vsevolod Lobko <seva@alex-ua.com>.
In kernel configuration file add
options OVERRIDE_CARD=2
options OVERRIDE_TUNER=11
options BKTR_USE_PLL
1.51 31 August 1998 Roger Hardiman <roger@cs.strath.ac.uk>
Fixed bug in Miro Tuner detection. Missing Goto.
Removed Hauppauge EEPROM 0x10 detection as I think
0x10 should be a PAL tuner, not NTSC.
Reinstated some Tuner Guesswork code from 1.27
1.52 3 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk>
Submitted patch by Vsevolod Lobko <seva@alex-ua.com>

Changed tuner code to autodetect tuner i2c address.
Addresses were incorrectly hardcoded.
1.55 21 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk>
Hauppauge Tech Support confirmed all Hauppauge 878
PAL/SECAM boards will use PLL mode.
Added to card probe. Thanks to Ken and Fred.

subtitles via /dev/vbi.
1.64 7 May 1999 Roger Hardiman <roger@freebsd.org>
Support LifeView FlyVideo 98 cards. Use EEPROM for card
autodetection. Use bttv's audio mux values.
Thanks to Paul Reece <paul@fastlane.net.au>,
Ivan Brawley <brawley@internode.com.au> and
Gilad Rom <rom_glsa@ein-hashofet.co.il>
Automatically locate the EEPROM i2c address and read the
subsystem_vendor_id from EEPROM and not the PCI registers.

same time. To capture VBI data, /dev/vbi must be opened
before starting video capture.
1.68 25 May 1999 Roger Hardiman <roger@freebsd.org>
Due to differences in PCI bus implementations from various
motherboard chipset manufactuers, the Bt878/Bt879 has 3
PCI bus compatibility modes. These are
NORMAL PCI 2.1 for proper PCI 2.1 compatible chipsets.
INTEL 430 FX for the Intel 430 FX chipset.
SIS VIA CHIPSET for certain SiS and VIA chipsets.
Older Intel and non-Intel chipsets may also benefit from
either 430_FX or SIS/VIA mode.
NORMAL PCI mode is enabled by default.
For INTEL 430 FX mode, add this to your kenel config:
options "BKTR_430_FX_MODE"
For SiS / VIA mode, add this to your kernel config:
options "BKTR_SIS_VIA_MODE"
Using quotes in these options is not needed in FreeBSD 4.x.
Note. Newer VIA chipsets should be fully PCI 2.1 compatible
and should work fine in the Default mode.
Also rename 849 to 849A, the correct name for the chip.
1.69 12 June 1999 Roger Hardiman <roger@freebsd.org>
Updates for FreeBSD 4.x device driver interface.
BSDI code removed. Will be restored later.
1.70 12 July 1999 Roger Hardiman <roger@freebsd.org>

Change number of VBI lines from 16 to 12 for NTSC formats.
Changes to probeCard() for better eeprom identification.
Added STB Bt878 card identification.
Add Hauppauge model identification to probeCard().
Added TDA9850 initialisation code taken from Linux bttv.
Juha.Nurmela@quicknet.inet.fi found/fixed bug in VBI_SLEEP.
Matt Brown <matt@dqc.org> added MSP3430G DBX initialisation.
1.71 30 Aug 1999 Roger Hardiman <roger@freebsd.org>
Small cleanup of OS dependant code. Remove NPCI usage.
Fix bug in AVerMedia detection.
Update VBI support for the AleVT Teletext package. Parts

* Tuner Notes:
* Programming the tuner properly is quite complicated.
* Here are some notes, based on a FM1246 data sheet for a PAL-I tuner.
* The tuner (front end) covers 45.75 Mhz - 855.25 Mhz and an FM band of
* 87.5 Mhz to 108.0 Mhz.
*
* RF and IF. RF = radio frequencies, it is the transmitted signal.
* IF is the Intermediate Frequency (the offset from the base
* signal where the video, color, audio and NICAM signals are.
*
* Eg, Picture at 38.9 Mhz, Colour at 34.47 MHz, sound at 32.9 MHz
* NICAM at 32.348 Mhz.
* Strangely enough, there is an IF (intermediate frequency) for
* FM Radio which is 10.7 Mhz.
*
* The tuner also works in Bands. Philips bands are
* FM radio band 87.50 to 108.00 MHz
* Low band 45.75 to 170.00 MHz
* Mid band 170.00 to 450.00 MHz
* High band 450.00 to 855.25 MHz
*
*
* Now we need to set the PLL on the tuner to the required freuqncy.
* It has a programmable divisor.
* For TV we want
* N = 16 (freq RF(pc) + freq IF(pc)) pc is picture carrier and RF and IF
* are in MHz.
* For RADIO we want a different equation.
* freq IF is 10.70 MHz (so the data sheet tells me)
* N = (freq RF + freq IF) / step size
* The step size must be set to 50 khz (so the data sheet tells me)
* (note this is 50 kHz, the other things are in MHz)
* so we end up with N = 20x(freq RF + 10.7)
*
