directly to a vga frame buffer which has
a linear frame buffer. Minor code clean-up.
1.3 2/23/97 Fixed system lock-up reported by
Randall Hopper <rhh@ct.picker.com>. This
problem seems somehow to be exhibited only
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.

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

1.31 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 lose 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>

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.

options OVERRIDE_TUNER=11
options BKTR_USE_PLL
1.51 31 August 1998 Roger Hardiman <roger@cs.strath.ac.uk>

Removed Hauppauge EEPROM 0x10 detection as I think
0x10 should be a PAL tuner, not NTSC.

Submitted patch by Vsevolod Lobko <seva@alex-ua.com>

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.

enabled by setting the sysctl, hw.bt848.slow_msp_audio to 1
before starting FXTV (or before opening /dev/bktrN)
2.09 20 Mar 2000 Thomas Klausner <wiz@danbala.ifoer.tuwien.ac.at> submitted
