Summary of DRI Driver Features

  • "YES" means that the feature is present in HW and supported by the driver.
  • "no" means that the feature is not present in the HW or driver.
  • "SW" means that the feature is not present in the HW, but is emulated by the driver anyway.
  • "HW" means that the feature is theoretically supported by the HW, but nobody's written the support into the driver. Yet.

  • "x" means "unknown." Nobody's bothered to fill in the blanks yet. Todo:

  • Nouveau guys, please add nVidia chipsets; I'm not familiar with your status.

  • Add the r300 driver.
