bktr
—
Brooktree Bt848/849/878/879 and
Pinnacle PCTV video capture driver
SYNOPSIS
device bktr
device iicbus
device iicbb
device smbus
DESCRIPTION
Thebktr
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 Meteor driver has since been removed. 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. Furthermore, 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
interconnected with an I2C bus. The Brooktree848 chips act as a master
device on the bus to control them. Therefore,
iicbus(4),
iicbb(4) and
smbus(4) controller declarations are mandatory to activate
bktr
support.
The following kernel parameters may be used to further configure 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
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 integer from 1 to
23 taken from the following table:
