bktr(4)

NAME

bktr - Brooktree Bt848/849/878/879 and Pinnacle PCTV video

capture driver

SYNOPSIS

device bktr
device iicbus
device iicbb
device smbus

DESCRIPTION

The bktr driver provides support for PCI video capture and

VBI capture on
low cost, high performance boards. The driver is based on

the Matrox
Meteor driver and uses the same API. The bktr driver should

support most
video cards based on the Brooktree Bt848/849/878/879 Video

Capture Chip.
Also supported are most Pinnacle PCTV video cards. Further

more, the
driver supports FM Radio if the tuner supports it.

The driver currently supports the following features:

PCI to PCI dma transfer
clipping
yuv
rgb16
rgb24
rgb32

On the supported cards, tuners and other components are in

terconnected
with an I2C bus. The Brooktree848 chips act as a master de

vice on the
bus to control them. Therefore, iicbus(4), iicbb(4) and sm

bus(4) controller declarations are mandatory to activate bktr support.

The following kernel parameters may be used to further con

figure the
driver:

options BROOKTREE_ALLOC_PAGES=xxx specifies the number of

contiguous
pages to allocate when successfully probed. The default

number of pages
allocated by the kernel is 216. This means that there are

(216*4096)
bytes available for use.

options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_NTSC One of these options can be used to set the default video

format for the
driver. This fixed random hangs and lockups with the Video

Logic Captivator PCI card.

The following sysctls may be used to further configure the

driver:

sysctl hw.bt848.card=nnnn This can be used to override the

card make
which was detected at boot time. `nnnn' is set to an inte

ger from 1 to
23 taken from the following table:
