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_NTSCOne of these options can be used to set the default video format for the driver. This fixed random hangs and lockups with the VideoLogic 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 integer from 1 to 23 taken from the following table:

| “ | Ken Thompson has an automobile which he helped design. Unlike most automobiles, it has neither speedometer, nor gas gauge, nor any of the other numerous idiot lights which plague the modern driver. Rather, if the driver makes a mistake, a giant “?” lights up in the center of the dashboard. “The experienced driver,” says Thompson, “will usually know what's wrong.” | ” |
