What's new

  • Vulkan has been updated to version 1.3.216.
  • OpenCL has been updated to version 3.0.11.
  • The VulkanSC ICD loader is now available as part of the com.qnx.qnx800.target.screen.base package. It is an experimental package.
  • New screen APIs have been added to manipulate float values:
    • screen_get_device_property_fv()
    • screen_set_device_property_fv()
    • screen_get_display_property_fv()
    • screen_set_display_property_fv()
    • screen_get_session_property_fv()
    • screen_set_session_property_fv()
    • screen_get_window_property_fv()
    • screen_set_window_property_fv()
  • The OpenWF Display Server (wfd-server) is now available as part of the com.qnx.qnx800.target.screen.base.wfd_server package. It is an experimental package.
    • The wfd-server is a resource manager that provides the ability to control display output independently from QNX Screen. The separation of the display controller from QNX Screen allows the display of critical elements directly to the display device through the use of OpenWF Display API in the event of a failure of other applications using QNX Screen or QNX Screen itself. The wfd-server package includes the resource manager, OpenWF Display API library, and demo and utility applications that highlight wfd-server capabilities and its potential use cases.
      Note:
      The wfd-server was tested on Imx8QM and j721e platforms only. Other platforms might have unexpected behavior.
  • A new SCREEN_PROPERTY_FOCUS_MODE display property has been added. This property enables Screen to tailor focus settings based on the specific connected display.
  • Support for the following Intel hardware has been added:
    • Elkhart Lake
    • Alder Lake
    • Tiger Lake
