94 Please refer to xorg.conf(5) for general configuration details. This
95 section only covers configuration details specific to this driver.
96 The following driver Options are supported:
98 Option "SWcursor" "boolean"
100 Selects software cursor. The default is off.
101 Option "Accel" "boolean"
103 Enables or disables all hardware acceleration.
104 The default is on.
105 Option "ZaphodHeads" "string"
107 Specify the RandR output(s) to use with zaphod mode for a par‐
108 ticular driver instance. If you use this option you must use
109 this option for all instances of the driver.
110 For example: Option "ZaphodHeads" "LVDS,VGA-0" will assign
111 xrandr outputs LVDS and VGA-0 to this instance of the driver.
112 Option "ColorTiling" "boolean"
114 The framebuffer can be addressed either in linear or tiled mode.
115 Tiled mode can provide significant performance benefits with 3D
116 applications. Tiling will be disabled if the drm module is too
117 old or if the current display configuration does not support it.
118 On R600+ this enables 1D tiling mode.
119 The default value is on for R/RV3XX, R/RV4XX, R/RV5XX, RS6XX,
120 RS740, R/RV6XX, R/RV7XX, RS780, RS880, EVERGREEN, CAYMAN, ARUBA,
121 Southern Islands, and Sea Islands and off for R/RV/RS1XX,
122 R/RV/RS2XX, RS3XX, and RS690/RS780/RS880 when fast fb feature is
123 enabled.
124 Option "ColorTiling2D" "boolean"
126 The framebuffer can be addressed either in linear, 1D, or 2D
127 tiled modes. 2D tiled mode can provide significant performance
128 benefits over 1D tiling with 3D applications. Tiling will be
129 disabled if the drm module is too old or if the current display
130 configuration does not support it. KMS ColorTiling2D is only
131 supported on R600 and newer chips and requires Mesa 9.0 or newer
132 for R6xx-ARUBA, Mesa 9.2 or newer for Southern Islands, and Mesa
133 10.1 or newer for Sea Islands.
134 The default value is on for R/RV6XX, R/RV7XX, RS780, RS880,
135 EVERGREEN, CAYMAN, ARUBA, Southern Islands, and Sea Islands.
136 Option "DRI" "integer"
138 Define the maximum level of DRI to enable. Valid values are 2
139 for DRI2 or 3 for DRI3. The default is 2 for DRI2.
140 Option "EnablePageFlip" "boolean"
142 Enable DRI2 page flipping. The default is on. Pageflipping is
143 supported on all radeon hardware.
144 Option "TearFree" "boolean"
146 Enable tearing prevention using the hardware page flipping mech‐
147 anism. This option currently doesn't have any effect for rotated
148 CRTCs. It requires allocating two separate scanout buffers for
149 each non-rotated CRTC. Enabling this option currently disables
150 Option "EnablePageFlip". The default is off.
151 Option "AccelMethod" "string"
153 Chooses between available acceleration architectures. Valid
154 values are EXA (for pre-TAHITI GPUs) and glamor (for R300 or
155 higher). The default is glamor as of TAHITI, otherwise EXA.
156 The following driver Options are supported for glamor :
159 Option "ShadowPrimary" "boolean"
161 This option enables a so-called "shadow primary" buffer for fast
162 CPU access to pixel data, and separate scanout buffers for each
163 display controller (CRTC). This may improve performance for
164 some 2D workloads, potentially at the expense of other (e.g. 3D,
165 video) workloads. Note in particular that enabling this option
166 currently disables page flipping. The default is off.
167 The following driver Options are supported for EXA :
170 Option "EXAVSync" "boolean"
172 This option attempts to avoid tearing by stalling the engine
173 until the display controller has passed the destination region.
174 It reduces tearing at the cost of performance and has been known
175 to cause instability on some chips. The default is off.
176 Option "EXAPixmaps" "boolean"
178 Under KMS, to avoid thrashing pixmaps in/out of VRAM on low mem‐
179 ory cards, we use a heuristic based on VRAM amount to determine
180 whether to allow EXA to use VRAM for non-essential pixmaps.
181 This option allows us to override the heuristic. The default is
182 on with > 32MB VRAM, off with < 32MB or when fast fb feature is
183 enabled for RS690/RS780/RS880.
184 Option "SwapbuffersWait" "boolean"
186 This option controls the behavior of glXSwapBuffers and glXCopy‐
187 SubBufferMESA calls by GL applications. If enabled, the calls
188 will avoid tearing by making sure the display scanline is out‐
189 side of the area to be copied before the copy occurs. If dis‐
190 abled, no scanline synchronization is performed, meaning tearing
191 will likely occur. Note that when enabled, this option can
192 adversely affect the framerate of applications that render
193 frames at less than refresh rate.
194 The default value is on.
196
199 The driver supports the following X11 Xv attributes for Textured Video.
200 You can use the "xvattr" tool to query/set those attributes at runtime.
201 XV_VSYNC
204 XV_VSYNC is used to control whether textured adapter synchro‐
205 nizes the screen update to the monitor vertical refresh to elim‐
206 inate tearing. It has two values: 'off'(0) and 'on'(1). The
207 default is 'on'(1).
208 XV_CRTC
211 XV_CRTC is used to control which display controller (crtc) the
212 textured adapter synchronizes the screen update with when
213 XV_VSYNC is enabled. The default, 'auto'(-1), will sync to the
214 display controller that more of the video is on; when this is
215 ambiguous, the display controller associated with the RandR pri‐
216 mary output is preferred. This attribute is useful for things
217 like clone mode where the user can best decide which display
218 should be synced. The default is 'auto'(-1).
219 XV_BICUBIC
222 XV_BICUBIC is used to control whether textured adapter should
223 apply a bicubic filter to smooth the output. It has three val‐
224 ues: 'off'(0), 'on'(1) and 'auto'(2). 'off' means never apply
225 the filter, 'on' means always apply the filter and 'auto' means
226 apply the filter only if the X and Y sizes are scaled to more
227 than double to avoid blurred output. Bicubic filtering is not
228 currently compatible with other Xv attributes like hue, con‐
229 trast, and brightness, and must be disabled to use those
230 attributes. The default is 'off'(0).
