programs that expect RGB data (e.g. gqcam) to work with this driver. If
your colors look VERY wrong, you may want to change this.
NAME: buf_timeout (Temporarily disabled. Memory is deallocated immediately)
TYPE: integer
DEFAULT: 5 (seconds)
DESC: Number of seconds before unused frame buffers are deallocated.
Previously, memory was allocated upon open() and deallocated upon
close(). Deallocation now occurs only if the driver is closed and this
timeout is reached. If you are capturing frames less frequently than
the default timeout, increase this. This will not make any difference
with programs that capture multiple frames during an open/close cycle.

instead of an image. This does not work correctly yet.
NAME: sensor_gbr (*** TEMPORARILY DISABLED ***)
TYPE: integer (Boolean)
DEFAULT: 0
DESC: This makes the sensor output GBR422 instead of YUV420. This saves the
driver the trouble of converting YUV to RGB, but it currently does not
work very well (the colors are not quite right)

automatically based on the custom ID of the OV511 device. In cases
where this fails, you can override this auto-detection. Please see

CONFIG_AGP
AGP (Accelerated Graphics Port) is a bus system mainly used to
connect graphics cards to the rest of the system.
If you have an AGP system and you say Y here, it will be possible to
use the AGP features of your 3D rendering video card. This code acts
as a sort of "AGP driver" for the motherboard's chipset.
If you need more texture memory than you can get with the AGP GART
(theoretically up to 256 MB, but in practice usually 64 or 128 MB
due to kernel allocation issues), you could use PCI accesses
and have up to a couple gigs of texture space.
Note that this is the only means to have XFree4/GLX use
write-combining with MTRR support on the AGP bus. Without it, OpenGL
direct rendering will be a lot slower but still faster than PIO.
You should say Y here if you use XFree86 3.3.6 or 4.x and want to
use GLX or DRI. If unsure, say N.
This driver is available as a module. If you want to compile it as
a module, say M here and read <file:Documentation/modules.txt>. The
module will be called agpgart.o.
CONFIG_AGP_INTEL
This option gives you AGP support for the GLX component of the
XFree86 4.x on Intel 440LX/BX/GX, 815, 820, 830, 840, 845, 850 and 860 chipsets.
You should say Y here if you use XFree86 3.3.6 or 4.x and want to
use GLX or DRI. If unsure, say N.
CONFIG_AGP_I810
This option gives you AGP support for the Xserver on the Intel 810
815 and 830m chipset boards for their on-board integrated graphics. This
is required to do any useful video modes with these boards.
CONFIG_AGP_I460
This option gives you AGP GART support for the Intel 460GX chipset
for IA64 processors.
CONFIG_AGP_VIA
This option gives you AGP support for the GLX component of the
XFree86 4.x on VIA MPV3/Apollo Pro chipsets.
You should say Y here if you use XFree86 3.3.6 or 4.x and want to
use GLX or DRI. If unsure, say N.
CONFIG_AGP_AMD
This option gives you AGP support for the GLX component of the
XFree86 4.x on AMD Irongate, 761, and 762 chipsets.
You should say Y here if you use XFree86 3.3.6 or 4.x and want to
use GLX or DRI. If unsure, say N.
CONFIG_AGP_SIS
This option gives you AGP support for the GLX component of the "soon
to be released" XFree86 4.x on Silicon Integrated Systems [SiS]
chipsets.
Note that 5591/5592 AGP chipsets are NOT supported.
You should say Y here if you use XFree86 3.3.6 or 4.x and want to
use GLX or DRI. If unsure, say N.
CONFIG_AGP_SWORKS
Say Y here to support the Serverworks AGP card. See
<http://www.serverworks.com/> for product descriptions and images.
CONFIG_AGP_ALI
This option gives you AGP support for the GLX component of the
XFree86 4.x on the following ALi chipsets. The supported chipsets
include M1541, M1621, M1631, M1632, M1641,M1647,and M1651.
For the ALi-chipset question, ALi suggests you refer to
<http://www.ali.com.tw/eng/support/index.shtml>.
The M1541 chipset can do AGP 1x and 2x, but note that there is an
acknowledged incompatibility with Matrox G200 cards. Due to
timing issues, this chipset cannot do AGP 2x with the G200.
This is a hardware limitation. AGP 1x seems to be fine, though.
You should say Y here if you use XFree86 3.3.6 or 4.x and want to
use GLX or DRI. If unsure, say N.
CONFIG_AGP_HP_ZX1
This option gives you AGP GART support for the HP ZX1 chipset
for IA64 processors.

Digital drives in the Expert series (by nature of really being IBM
drives).
If you have such a drive, say Y here.
However, please, note that there are host chip controllers which will
not cooperate properly if TCQ is enabled. This may cause serious
data loss!
Since enabling TCQ doesn't appear to have any noticeable performance
impact on Linux: [feel free to correct me if you wish too please]
Generally say N here.
