Bttv driver linux

7. The bttv driver; 8. The cafe_ccic driver; 9. The cpia2 driver; The cx18 driver; The cxx driver; The cx88 driver; The VPBE V4L2 driver design; The Samsung S5P/EXYNOS4 FIMC driver; The ivtv driver; Vaio Picturebook Motion Eye Camera Driver; OMAP 3 Image Signal Processor (ISP) driver; OMAP4 ISS Driver; Both bttv and btaudio have a insmod option to set the PCI latency of the device. Some mainboard have problems to deal correctly with multiple devices doing DMA at the same time. bttv + ide seems to cause this sometimes, if this is the case you likely see freezes only with video and hard disk access at the same time. The Bttv Driver. Drivers for Bt8x8-based hardware have been a part of the Linuxkernelsince version , and are likely to be already enabled in your running kernel if you have not recompiled or otherwise replaced your system's stock kernel with a custom version. If unavailable, Bt8x8 support can be enabled two ways.

Bttv devices are collectively those PCI cards that are based upon either a Bt, Bt or Fusion A chip, and which are supported under Linux by the bttv and associated kernel driver modules. These devices can be capture-only cards - which means video is taken directly from a video source without the use of a tuner - or they can be TV cards which make use of RF tuner circuitry to receive television signals and the capture chip is there to decode the extracted video and audio. linux/drivers/media/pci/bt8xx/bttv-driver.c 1) The resource must be allocated when we enter buffer prepare functions and remain allocated while buffers are in the 2) This is a single frame read. 3) VIDIOC_S_FBUF and VIDIOC_S_FMT (OVERLAY) still work when RESOURCE_OVERLAY is allocated. 4) This. bttv is a kernel driver module meant to support any PCI card that uses a Bt, Bt or Fusion A chip for video capture, which, taken collectively, are known as Bttv devices (bt, bt). Contents.

bttv uses the PCI Subsystem ID to autodetect the card type. lspci lists the a.0 Multimedia video controller: Brooktree Corporation Bt (rev 02).

Signed integer overflow in the bttv_read function in the bttv driver (bttv-driver.c) in Linux kernel before has unknown impact and attack vectors.
