---help---
This is a video4linux driver for Conexant cx23416 or cx23415 based
PCI personal video recorder devices.
This is used in devices such as the Hauppauge PVR-150/250/350/500
cards. There is a driver homepage at <http://www.ivtvdriver.org>.
To compile this driver as a module, choose M here: the
module will be called ivtv.
config VIDEO_IVTV_ALSA
tristate "Conexant cx23415/cx23416 ALSA interface for PCM audio capture"
depends on VIDEO_IVTV && SND
select SND_PCM
---help---
This driver provides an ALSA interface as another method for user
applications to obtain PCM audio data from Conexant cx23415/cx23416
based PCI TV cards supported by the ivtv driver.
The ALSA interface has much wider use in user applications performing
PCM audio capture, than the V4L2 "/dev/video24" PCM audio interface
provided by the main ivtv driver.
To compile this driver as a module, choose M here: the
module will be called ivtv-alsa.
config VIDEO_FB_IVTV
tristate "Conexant cx23415 framebuffer support"
depends on VIDEO_IVTV && FB
select FB_CFB_FILLRECT
select FB_CFB_COPYAREA
select FB_CFB_IMAGEBLIT
---help---
This is a framebuffer driver for the Conexant cx23415 MPEG
encoder/decoder.
This is used in the Hauppauge PVR-350 card. There is a driver
homepage at <http://www.ivtvdriver.org>.
x86/mm/pat, drivers/media/ivtv: Use arch_phys_wc_add() and require PAT disabled We are burrying direct access to MTRR code support on x86 in order to take advantage of PAT. In the future, we also want to make the default behavior of ioremap_nocache() to use strong UC, at which point the use of mtrr_add() on those systems would make write-combining void. In order to help both enable us to later make strong UC default and in order to phase out direct MTRR access code, port the driver over to the arch_phys_wc_add() API and annotate that the device driver requires systems to boot with PAT disabled, with the 'nopat' kernel parameter. This is a workable compromise given that the hardware is really rare these days, and perhaps only some lost souls stuck with obsolete hardware are expected to be using this feature of the device driver.

In order to use this module, you will need to boot with PAT disabled
on x86 systems, using the nopat kernel parameter.
To compile this driver as a module, choose M here: the
module will be called ivtvfb.
