.SH CONFIGURATION DETAILS
|
|
Please refer to __xconfigfile__(__filemansuffix__) for general configuration
|
|
details. This section only covers configuration details specific to this
|
|
driver.
|
|
.PP
|
|
The following driver
|
|
.B Options
|
|
are supported:
|
|
.TP
|
|
.BI "Option \*qSWcursor\*q \*q" boolean \*q
|
|
Selects software cursor. The default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qAccel\*q \*q" boolean \*q
|
|
Enables or disables all hardware acceleration.
|
|
.br
|
|
The default is
|
|
.B on.
|
|
|
|
.TP
|
|
.BI "Option \*qZaphodHeads\*q \*q" string \*q
|
|
Specify the RandR output(s) to use with zaphod mode for a particular driver
|
|
instance. If you use this option you must use this option for all instances
|
|
of the driver.
|
|
.br
|
|
For example:
|
|
.B
|
|
Option \*qZaphodHeads\*q \*qLVDS,VGA-0\*q
|
|
will assign xrandr outputs LVDS and VGA-0 to this instance of the driver.
|
|
.TP
|
|
.BI "Option \*qDRI\*q \*q" integer \*q
|
|
Define the maximum level of DRI to enable. Valid values are 2 for DRI2 or 3 for DRI3.
|
|
The default is
|
|
.B 3 for DRI3
|
|
if the Xorg version is >= 1.18.3, otherwise
|
|
.B 2 for DRI2.
|
|
.TP
|
|
.BI "Option \*qEnablePageFlip\*q \*q" boolean \*q
|
|
Enable DRI2 page flipping. The default is
|
|
.B on.
|
|
.TP
|
|
.BI "Option \*qTearFree\*q \*q" boolean \*q
|
|
Set the default value of the per-output 'TearFree' property, which controls
|
|
tearing prevention using the hardware page flipping mechanism. TearFree is
|
|
on for any CRTC associated with one or more outputs with TearFree on. Two
|
|
separate scanout buffers need to be allocated for each CRTC with TearFree
|
|
on. If this option is set, the default value of the property is 'on' or 'off'
|
|
accordingly. If this option isn't set, the default value of the property is
|
|
.B auto,
|
|
which means that TearFree is on for rotated outputs, outputs with RandR
|
|
transforms applied and for RandR 1.4 slave outputs, otherwise off.
|
|
.TP
|
|
.BI "Option \*qVariableRefresh\*q \*q" boolean \*q
|
|
Enables support for enabling variable refresh on the Screen's CRTCs
|
|
when an suitable application is flipping via the Present extension.
|
|
.br
|
|
The default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qAccelMethod\*q \*q" string \*q
|
|
Setting this option to
|
|
.B none
|
|
disables use of the glamor acceleration architecture. In that case, all 2D
|
|
rendering is done by the CPU, but 3D and video hardware acceleration can still
|
|
work. This is mainly useful for OpenGL driver bring-up.
|
|
.br
|
|
The default is to use glamor.
|
|
|
|
.PP
|
|
The following driver
|
|
.B Option
|
|
is supported for
|
|
.B glamor
|
|
:
|
|
.TP
|
|
.BI "Option \*qShadowPrimary\*q \*q" boolean \*q
|
|
This option enables a so-called "shadow primary" buffer for fast CPU access to
|
|
pixel data, and separate scanout buffers for each display controller (CRTC).
|
|
This may improve performance for some 2D workloads, potentially at the expense
|
|
of other (e.g. 3D, video) workloads.
|
|
Note in particular that enabling this option currently disables page flipping.
|
|
The default is
|
|
.B off.
