This sec- tion only covers configuration details specific to this driver. The driver auto-detects all device information necessary to initialize the card. However, if you have problems with auto-detection, you can specify for UMS (Userspace Modesetting): VideoRam - in kilobytes MemBase - physical address of the linear framebuffer IOBase - physical address of the MMIO registers ChipID - PCI DEVICE ID In addition, the following driver Options are supported for both UMS (User- space Modesetting) and KMS (Kernel Modesetting): Option "SWcursor" "boolean" Selects software cursor. The default is off. Option "NoAccel" "boolean" Enables or disables all hardware acceleration. The default is to enable hardware acceleration. Option "ZaphodHeads" "string" 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. For example: Option "ZaphodHeads" "LVDS,VGA-0" will assign xrandr outputs LVDS and VGA-0 to this instance of the driver. Option "EXAVSync" "boolean" This option attempts to avoid tearing by stalling the engine until the display controller has passed the destination region. It re- duces tearing at the cost of performance and has been known to cause instability on some chips. The default is off. The following driver Options are supported for KMS (Kernel Modesetting): Option "ColorTiling" "boolean" The framebuffer can be addressed either in linear or tiled mode. Tiled mode can provide significant performance benefits with 3D ap- plications. Tiling will be disabled if the drm module is too old or if the current display configuration does not support it. On R600+ this enables 1D tiling mode. The default value is on for R/RV3XX, R/RV4XX, R/RV5XX, RS6XX, RS740, R/RV6XX, R/RV7XX, RS780, RS880, EVERGREEN, and CAYMAN and off for R/RV/RS1XX, R/RV/RS2XX, and RS3XX. Option "ColorTiling2D" "boolean" The framebuffer can be addressed either in linear, 1D, or 2D tiled modes. 2D tiled mode can provide significant performance benefits over 1D tiling with 3D applications. Tiling will be disabled if the drm module is too old or if the current display configuration does not support it. KMS ColorTiling2D is only supported on R600 and newer chips. The default value is off for R/RV6XX, R/RV7XX, RS780, RS880, EVER- GREEN, and CAYMAN. Option "EXAPixmaps" "boolean" Under KMS, to avoid thrashing pixmaps in/out of VRAM on low memory cards, we use a heuristic based on VRAM amount to determine whether to allow EXA to use VRAM for non-essential pixmaps. This option al- lows us to override the heuristic. The default is on with > 32MB VRAM, off with < 32MB. Option "SwapbuffersWait" "boolean" This option controls the behavior of glXSwapBuffers and glXCopySub- BufferMESA calls by GL applications. If enabled, the calls will avoid tearing by making sure the display scanline is outside of the area to be copied before the copy occurs. If disabled, no scanline synchronization is performed, meaning tearing will likely occur. Note that when enabled, this option can adversely affect the framer- ate of applications that render frames at less than refresh rate. The default value is on. Option "EnablePageFlip" "boolean" Enable DRI2 page flipping. The default is on. Pageflipping is sup- ported on all radeon hardware. The following driver Options are supported for UMS (Userspace Modesetting): Option "Dac6Bit" "boolean" Enables or disables the use of 6 bits per color component when in 8 bpp mode (emulates VGA mode). By default, all 8 bits per color com- ponent are used. The default is off. Option "VideoKey" "integer" This overrides the default pixel value for the YUV video overlay key. The default value is 0x1E. Option "ScalerWidth" "integer" This sets the overlay scaler buffer width. Accepted values range from 1024 to 2048, divisible by 64. Values other than 1536 and 1920 may not make sense. This should be set automatically, but no one knows what the limit is for which chip. If you think quality is not optimal when playing back HD video (with horizontal resolution larger than this setting), increase this value. If you get an empty area at the right (usually pink), decrease it. Note that this only affects the "true" overlay via Xv, and won't affect things like tex- tured video. The default value is either 1536 (for most chips) or 1920. Option "AGPMode" "integer" Set AGP data transfer rate. (used only when DRI is enabled) 1 -- 1x (before AGP v3 only) 2 -- 2x (before AGP v3 only) 4 -- 4x 8 -- 8x (AGP v3 only) others -- invalid The default is to leave it unchanged. Option "AGPFastWrite" "boolean" Enable AGP fast writes. Enabling this is frequently the cause of instability. Used only when the DRI is enabled. If you enable this option you will get *NO* support from developers. The default is off. Option "BusType" "string" Used to replace previous ForcePCIMode option. Should only be used when driver's bus detection is incorrect or you want to force an AGP card to PCI mode. You should NEVER force a PCI card to AGP bus. PCI -- PCI bus AGP -- AGP bus PCIE -- PCI Express bus (used only when DRI is enabled) The default is auto detect. Option "DisplayPriority" "string" Used to prevent flickering or tearing problem caused by display buffer underflow. AUTO -- Driver calculated (default). BIOS -- Remain unchanged from BIOS setting. Use this if the calculation is not correct for your card. HIGH -- Force to the highest priority. Use this if you have problem with above options. This may affect performance slightly. The default value is AUTO. Option "ColorTiling" "boolean" The framebuffer can be addressed either in linear or tiled mode. Tiled mode can provide significant performance benefits with 3D ap- plications. For 2D it shouldn't matter much. Tiling will be dis- abled if the virtual x resolution exceeds 2048 (3968 for R300 and above), or if DRI is enabled and the drm module is too old. If this option is enabled, a new DRI driver is required for direct rendering. Color tiling will be automatically disabled in interlaced or dou- blescan screen modes. The default value is on. Option "IgnoreEDID" "boolean" Do not use EDID data for mode validation. DDC is still used for monitor detection. This is different from NoDDC option. The default value is off. Option "CustomEDID" "string" Forces the X driver to use the EDID data specified in a file rather than the display's EDID. Also overrides DDC monitor detection. You may specify a semicolon-separated list of output name and file- name pairs with an optional flag, "digital" or "analog", to override the digital bit in the EDID which is used by the driver to determine whether to use the analog or digital encoder associated with a DVI-I port. The output name is the RandR output name, e.g., "VGA-0" or "DVI-0"; consult the Xorg log for the supported output names of any given system. The file must contain a raw 128-byte EDID block, as captured by get- edid. For example: Option "CustomEDID" "VGA-0:/tmp/edid1.bin; DVI-0:/tmp/edid2.bin:digital" will assign the EDID from the file /tmp/edid1.bin to the output device VGA-0, and the EDID from the file /tmp/edid2.bin to the output device DVI-0 and force the DVI port to use the digital encoder. Note that an output name must always be specified, even if only one EDID is specified. Caution: Specifying an EDID that doesn't exactly match your display may damage your hardware, as it allows the driver to specify timings beyond the capabilities of your display. Use with care. Option "PanelSize" "string" Should only be used when driver cannot detect the correct panel size. Apply to both desktop (TMDS) and laptop (LVDS) digital pan- els. When a valid panel size is specified, the timings collected from DDC and BIOS will not be used. If you have a panel with timings different from that of a standard VESA mode, you have to provide this information through the Modeline. For example, Option "PanelSize" "1400x1050" The default value is none. Option "EnablePageFlip" "boolean" Enable page flipping for 3D acceleration. This will increase perfor- mance but not work correctly in some rare cases, hence the default is off. It is currently only supported on R/RV/RS4xx and older hardware. Option "ForceMinDotClock" "frequency" Override minimum dot clock. Some Radeon BIOSes report a minimum dot clock unsuitable (too high) for use with television sets even when they actually can produce lower dot clocks. If this is the case you can override the value here. Note that using this option may damage your hardware. You have been warned. The frequency parameter may be specified as a float value with standard suffixes like "k", "kHz", "M", "MHz". Option "RenderAccel" "boolean" Enables or disables hardware Render acceleration. It is supported on all Radeon cards when using EXA acceleration and on Radeon R/RV/RS1xx, R/RV/RS2xx and RS3xx when using XAA. The default is to enable Render acceleration. Option "AccelMethod" "string" Chooses between available acceleration architectures. Valid options are XAA and EXA. XAA is the traditional acceleration architecture and support for it is very stable. EXA is a newer acceleration ar- chitecture with better performance for the Render and Composite ex- tensions. The default is EXA. Option "AccelDFS" "boolean" Use or don't use accelerated EXA DownloadFromScreen hook when possi- ble (only when Direct Rendering is enabled, e.g.). Default: off with AGP due to issues with GPU->host transfers with some AGP bridges, on otherwise. Option "FBTexPercent" "integer" Amount of video RAM to reserve for OpenGL textures, in percent. With EXA, the remainder of video RAM is reserved for EXA offscreen man- agement. Specifying 0 results in all offscreen video RAM being re- served for EXA and only GART memory being available for OpenGL tex- tures. This may improve EXA performance, but beware that it may cause problems with OpenGL drivers from Mesa versions older than 6.4. With XAA, specifying lower percentage than what gets reserved without this option has no effect, but the driver tries to increase the video RAM reserved for textures to the amount specified roughly. Default: 50. Option "DepthBits" "integer" Precision in bits per pixel of the shared depth buffer used for 3D acceleration. Valid values are 16 and 24. When this is 24, there will also be a hardware accelerated stencil buffer, but the combined depth/stencil buffer will take up twice as much video RAM as when it's 16. Default: The same as the screen depth. Option "DMAForXv" "boolean" Try or don't try to use DMA for Xv image transfers. This will reduce CPU usage when playing big videos like DVDs, but may cause instabil- ities. Default: on. Option "SubPixelOrder" "string" Force subpixel order to specified order. Subpixel order is used for subpixel decimation on flat panels. NONE -- No subpixel (CRT like displays) RGB -- in horizontal RGB order (most flat panels) BGR -- in horizontal BGR order (some flat panels) This option is intended to be used in following cases: 1. The default subpixel order is incorrect for your panel. 2. Enable subpixel decimation on analog panels. 3. Adjust to one display type in dual-head clone mode setup. 4. Get better performance with Render acceleration on digital panels (use NONE setting). The default is NONE for CRT, RGB for digital panels Option "ClockGating" "boolean" Enable dynamic clock gating. This can help reduce heat and increase battery life by reducing power usage. Some users report reduced 3D performance with this enabled. The default is off. Option "ForceLowPowerMode" "boolean" Enable a static low power mode. This can help reduce heat and in- crease battery life by reducing power usage at the expense of per- formance. The default is off. Option "DynamicPM" "boolean" Enable dynamic power mode switching. This can help reduce heat and increase battery life by reducing power usage when the system is idle (DPMS active). The default is off. Option "VGAAccess" "boolean" Tell the driver if it can do legacy VGA IOs to the card. This is necessary for properly resuming consoles when in VGA text mode, but shouldn't be if the console is using radeonfb or some other graphic mode driver. Some platforms like PowerPC have issues with those, and they aren't necessary unless you have a real text mode in console. The default is off on PowerPC and SPARC and on on other architec- tures. Option "ReverseDDC" "boolean" When BIOS connector information isn't available, use this option to reverse the mapping of the two main DDC ports. Use this if the X server obviously detects the wrong display for each connector. This is typically needed on the Radeon 9600 cards bundled with Apple G5s. The default is off. Option "LVDSProbePLL" "boolean" When BIOS panel information isn't available (like on PowerBooks), it may still be necessary to use the firmware-provided PLL values for the panel or flickering will happen. This option will force probing of the current value programmed in the chip when X is launched in that case. This is only useful for LVDS panels (laptop internal panels). The default is on. Option "TVDACLoadDetect" "boolean" Enable load detection on the TV DAC. The TV DAC is used to drive both TV-out and analog monitors. Load detection is often unreliable in the TV DAC so it is disabled by default. The default is off. Option "DefaultTMDSPLL" "boolean" Use the default driver provided TMDS PLL values rather than the ones provided by the BIOS. This option has no effect on Mac cards. En- able this option if you are having problems with a DVI monitor using the internal TMDS controller. The default is off. Option "DefaultTVDACAdj" "boolean" Use the default driver provided TVDAC Adj values rather than the ones provided by the BIOS. This option has no effect on Mac cards. Enable this option if you are having problems with a washed out dis- play on the secondary DAC. The default is off. Option "DRI" "boolean" Enable DRI support. This option allows you to enable to disable the DRI. The default is off for RN50/ES1000 and on for others. Option "DefaultConnectorTable" "boolean" Enable this option to skip the BIOS connector table parsing and use the driver defaults for each chip. The default is off Option "MacModel" "string" Used to specify Mac models for connector tables and quirks. If you have a PowerBook or Mini with DVI that does not work properly, try the alternate options as Apple does not seem to provide a good way of knowing whether they use internal or external TMDS for DVI. Only valid on PowerPC. On Linux, the driver will attempt to detect the MacModel automatically. ibook -- ibooks powerbook-external -- Powerbooks with external DVI powerbook-internal -- Powerbooks with integrated DVI powerbook-vga -- Powerbooks with VGA rather than DVI mini-external -- Mac Mini with external DVI mini-internal -- Mac Mini with integrated DVI imac-g5-isight -- iMac G5 iSight emac -- eMac G4 sam440ep -- SAM440ep embedded board The default value is undefined. Option "TVStandard" "string" Used to specify the default TV standard if you want to use something other than the BIOS default. Valid options are: ntsc pal pal-m pal-60 ntsc-j scart-pal The default value is undefined. Option "ForceTVOut" "boolean" Enable this option to force TV-out to always be detected as at- tached. The default is off Option "IgnoreLidStatus" "boolean" Enable this option to ignore lid status on laptops and always detect LVDS as attached. The default is on. Option "Int10" "boolean" This option allows you to disable INT10 initialization. Set this to False if you are experiencing a hang when initializing a secondary card. The default is on. Option "ATOMTvOut" "boolean" This option enables experimental TV-out support for R/RV5xx, R/RV6xx, and R/RV7xx AtomBIOS chips. TV-out is experimental and may not function on these chips as well as hoped for. The default is off. Option "R4xxATOM" "boolean" This option enables modesetting on R/RV4xx chips using AtomBIOS. The default is off. TEXTURED VIDEO ATTRIBUTES The driver supports the following X11 Xv attributes for Textured Video. You can use the "xvattr" tool to query/set those attributes at runtime. XV_VSYNC XV_VSYNC is used to control whether textured adapter synchronizes the screen update to the monitor vertical refresh to eliminate tear- ing. It has two values: 'off'(0) and 'on'(1). The default is 'on'(1). XV_CRTC XV_CRTC is used to control which display controller (crtc) the tex- tured adapter synchronizes the screen update with when XV_VSYNC is enabled. The default, 'auto'(-1), will sync to the display con- troller that more of the video is on; when this is ambiguous, the display controller associated with the RandR primary output is pre- ferred. This attribute is useful for things like clone mode where the user can best decide which display should be synced. The de- fault is 'auto'(-1). XV_BICUBIC XV_BICUBIC is used to control whether textured adapter should apply a bicubic filter to smooth the output. It has three values: 'off'(0), 'on'(1) and 'auto'(2). 'off' means never apply the filter, 'on' means always apply the filter and 'auto' means apply the filter only if the X and Y sizes are scaled to more than double to avoid blurred output. Bicubic filtering is not currently compatible with other Xv attributes like hue, contrast, and brightness, and must be disabled to use those attributes. The default is 'off'(0).
