95 Please refer to xorg.conf(5) for general configuration details. This
96 section only covers configuration details specific to this driver.
97 The following driver Options are supported:
99 Option "SWcursor" "boolean"
101 Selects software cursor. The default is off.
102 Option "Accel" "boolean"
104 Enables or disables all hardware acceleration.
105 The default is on.
106 Option "ZaphodHeads" "string"
108 Specify the RandR output(s) to use with zaphod mode for a par‐
109 ticular driver instance. If you use this option you must use
110 this option for all instances of the driver.
111 For example: Option "ZaphodHeads" "LVDS,VGA-0" will assign
112 xrandr outputs LVDS and VGA-0 to this instance of the driver.
113 Option "ColorTiling" "boolean"
115 The framebuffer can be addressed either in linear or tiled mode.
116 Tiled mode can provide significant performance benefits with 3D
117 applications. Tiling will be disabled if the drm module is too
118 old or if the current display configuration does not support it.
119 On R600+ this enables 1D tiling mode.
120 The default value is on for R/RV3XX, R/RV4XX, R/RV5XX, RS6XX,
121 RS740, R/RV6XX, R/RV7XX, RS780, RS880, EVERGREEN, CAYMAN, ARUBA,
122 Southern Islands, and Sea Islands and off for R/RV/RS1XX,
123 R/RV/RS2XX, RS3XX, and RS690/RS780/RS880 when fast fb feature is
124 enabled.
125 Option "ColorTiling2D" "boolean"
127 The framebuffer can be addressed either in linear, 1D, or 2D
128 tiled modes. 2D tiled mode can provide significant performance
129 benefits over 1D tiling with 3D applications. Tiling will be
130 disabled if the drm module is too old or if the current display
131 configuration does not support it. KMS ColorTiling2D is only
132 supported on R600 and newer chips and requires Mesa 9.0 or newer
133 for R6xx-ARUBA, Mesa 9.2 or newer for Southern Islands, and Mesa
134 10.1 or newer for Sea Islands.
135 The default value is on for R/RV6XX, R/RV7XX, RS780, RS880,
136 EVERGREEN, CAYMAN, ARUBA, Southern Islands, and Sea Islands.
137 Option "DRI" "integer"
139 Define the maximum level of DRI to enable. Valid values are 2
140 for DRI2 or 3 for DRI3. The default is 3 for DRI3 if the Xorg
141 version is >= 1.18.3 and glamor is enabled, otherwise 2 for
142 DRI2. Note: DRI3 may not work correctly in all cases with EXA,
143 enable at your own risk.
144 Option "EnablePageFlip" "boolean"
146 Enable DRI2 page flipping. The default is on. Pageflipping is
147 supported on all radeon hardware.
148 Option "TearFree" "boolean"
150 Set the default value of the per-output 'TearFree' property,
151 which controls tearing prevention using the hardware page flip‐
152 ping mechanism. TearFree is on for any CRTC associated with one
153 or more outputs with TearFree on. Two separate scanout buffers
154 need to be allocated for each CRTC with TearFree on. If this
155 option is set, the default value of the property is 'on' or
156 'off' accordingly. If this option isn't set, the default value
157 of the property is auto, which means that TearFree is on for
158 rotated outputs, outputs with RandR transforms applied and for
159 RandR 1.4 slave outputs, otherwise off.
160 Option "AccelMethod" "string"
162 Chooses between available acceleration architectures. Valid
163 values are EXA (for pre-TAHITI GPUs) and glamor (for R300 or
164 higher). The default is glamor with R600 or newer (with Xorg >=
165 1.18.3, otherwise with TAHITI or newer), otherwise EXA.
166 The following driver Options are supported for glamor :
169 Option "ShadowPrimary" "boolean"
171 This option enables a so-called "shadow primary" buffer for fast
172 CPU access to pixel data, and separate scanout buffers for each
173 display controller (CRTC). This may improve performance for
174 some 2D workloads, potentially at the expense of other (e.g. 3D,
175 video) workloads. Note in particular that enabling this option
176 currently disables page flipping. The default is off.
177 The following driver Options are supported for EXA :
180 Option "EXAVSync" "boolean"
182 This option attempts to avoid tearing by stalling the engine
183 until the display controller has passed the destination region.
184 It reduces tearing at the cost of performance and has been known
185 to cause instability on some chips. The default is off.
186 Option "EXAPixmaps" "boolean"
188 Under KMS, to avoid thrashing pixmaps in/out of VRAM on low mem‐
189 ory cards, we use a heuristic based on VRAM amount to determine
190 whether to allow EXA to use VRAM for non-essential pixmaps.
191 This option allows us to override the heuristic. The default is
192 on with > 32MB VRAM, off with < 32MB or when fast fb feature is
193 enabled for RS690/RS780/RS880.
194 Option "SwapbuffersWait" "boolean"
196 This option controls the behavior of glXSwapBuffers and glXCopy‐
197 SubBufferMESA calls by GL applications. If enabled, the calls
198 will avoid tearing by making sure the display scanline is out‐
199 side of the area to be copied before the copy occurs. If dis‐
200 abled, no scanline synchronization is performed, meaning tearing
201 will likely occur. Note that when enabled, this option can
202 adversely affect the framerate of applications that render
203 frames at less than refresh rate.
204 The default value is on.
206
209 The driver supports the following X11 Xv attributes for Textured Video.
210 You can use the "xvattr" tool to query/set those attributes at runtime.
211 XV_VSYNC
214 XV_VSYNC is used to control whether textured adapter synchro‐
215 nizes the screen update to the monitor vertical refresh to elim‐
216 inate tearing. It has two values: 'off'(0) and 'on'(1). The
217 default is 'on'(1).
218 XV_CRTC
221 XV_CRTC is used to control which display controller (crtc) the
222 textured adapter synchronizes the screen update with when
223 XV_VSYNC is enabled. The default, 'auto'(-1), will sync to the
224 display controller that more of the video is on; when this is
225 ambiguous, the display controller associated with the RandR pri‐
226 mary output is preferred. This attribute is useful for things
227 like clone mode where the user can best decide which display
228 should be synced. The default is 'auto'(-1).
229 XV_BICUBIC
232 XV_BICUBIC is used to control whether textured adapter should
233 apply a bicubic filter to smooth the output. It has three val‐
234 ues: 'off'(0), 'on'(1) and 'auto'(2). 'off' means never apply
235 the filter, 'on' means always apply the filter and 'auto' means
236 apply the filter only if the X and Y sizes are scaled to more
237 than double to avoid blurred output. Bicubic filtering is not
238 currently compatible with other Xv attributes like hue, con‐
239 trast, and brightness, and must be disabled to use those
240 attributes. The default is 'off'(0).
