    Enlightment

Agenda

  • texture/pixmap update (graeme/ricardo)
  • clutk/unity update (jammy)
  • omap3 sgx meego drivers (asac)
  • omap4 driver update (ricardo)
  • xorg driver update (asac)
  • call for testing head acceleration with drivers: efl + qt
  • opengl rendering sinks -> graphics WG topic?

  • asac off next week

Minutes

  • Alexander on vacation next week
    • Jesse was going to lead next week's session, anyway :)

  • OpenGL rendering sinks
  • Clutter texture pixmap EGL (Alexandros, Ricardo)
    • Needs EGL image_pixmap extension.
      • In Mesa only available for drivers using the dri backend.
    • Alexandros tested example from mesa-demos and it too fails to work with EGL image extension.
      • Seems to need image_pixmap although EGL image is supposed to be deprecated superset of EGL image_pixmap.
    • ACTION: Ricardo to try Graeme's clutter EGL tfp patch on OMAP4.
    • ACTION: Alexandros to roll out EGL tfp enabled clutter package to facilitate Ricardo's test.
  • Clutk/Unity (Jammy, Ricardo)
    • Unity on freescale (Jammy)
      • segv when running Unity.
      • Perhaps tfp related?
      • Will build with debug info to get a more useful backtrace.
    • Unity on OMAP4 (Ricardo)
      • Mostly runs ok \o/.
      • Intermittent font rendering issues.
      • Font issues believed to be an issue with font cache in pango (Fabrice Olivero looking into this).
    • General need for full-debug packages
      • No debug symbols on PPA. May help debugging / backtrace.
      • Seems one needs to recompile from sources anyway.
      • Where to find the sources? Are source packages not enough? With patches applied?
      • Need to rebuild without optimizations for sane single step capabilities.
      • ACTION: Alexander to query about full-debug package support.
  • OMAP4 driver
    • No EULA for OMAP4!
    • Binary drivers for GL and X. Only kernel source open.
    • Is in private PPA, not yet cleared for public PPA (non-technical reasons).
  • OMAP3 driver
    • OMAP3 driver is maintained for meego (http://repo.meego.com).

    • Should be better than TI (seems they have added tfp support).
    • Alexandros tried meego GL drivers, but couldn't get them to work. Perhaps they are not compatible with our kernel modules?
    • ACTION: Ricardo to take a look at meego OMAP3 drivers.
  • Test -efl and -plasma images with OpenGL ES 2.0
    • Qt/X11 with ES 2.0 support in ppa:asac/armel2
    • EVAS with ES 2.0 support in ppa:asac/armel1
      • Need to export ELM_ENGINE=gl
  • HDMI
    • Nothing specific to do for HDMI from graphics point of view.
    • OMAP3 beagleboard has DVI, OMAP4 has real HDMI.

Actions

  • Ricardo to try Graeme's clutter EGL tfp patch on OMAP4.
  • Alexandros to roll out EGL tfp enabled clutter package to facilitate Ricardo's test.
  • Alexander to query about full-debug package support.
  • Ricardo to take a look at meego OMAP3 drivers.
