  • All to sign for session they want to lead at UDS/LDS in provided wiki page.
  • Whoever has patches for the OMAP4 driver send them to Vincent or Jeff at TI.
  • Ricardo to give the meego kernel drivers a try (doesn't hope for much, though)

Action Items from Previous Meeting

  • [Deferred] Alexander to query about full-debug package support.

Minutes

  • UDS/LDS
    • Will have a general session per toolkit, compositor etc and additional breakout sessions as required.
    • Get drivers to work, provide recipes for partners not familiar with Xorg driver development.
    • Need to define baseline features that drivers need to support.
    • Real world validation test cases.
  • Call for summit drafters for UDS/LDS
    • ACTION: Alexandros to create a wiki page so people can sign up for session leading.
    • ACTION: All to sign for session they want to lead at UDS/LDS in provided wiki page.
  • Clutter EGL tfp (Ricardo)
    • OMAP4
      • Driver supports EGL_KHR_image_pixmap but does not advertise it.
      • ACTION: .Whoever has patches for the OMAP4 driver send them to Vincent or Jeff at TI.
    • OMAP3
      • It seems to be supported with meego drivers.
      • Meego sgx drivers use a different kernel driver than the Ubuntu ones.
      • The accel. hardware use in N900 is slightly different than the BeagleBoard.

      • ACTION: Ricardo to give the meego kernel drivers a try (doesn't hope for much, though)
  • Glyph issue in unity gles2 on OMAP4 (Vincent)
    • Is related to mipmapping.
    • Workaround is to disable mipmapping in clutter.
  • Clutk (Jammy)
    • Segfault are related to gles2/cogl interleaving.
    • It's difficult to get the GL state when this happens, so as to make a more targeted fix.
    • Workaround patch is available
      • Verified on mesa x86, OMAP3 and imx51
      • There are still problems with freescale drivers. Investigation is in progress.
  • Xorg driver update (Jesse)
    • ARM to release enough code for a basic open source X driver for Mali.
    • Schedule slipped back about a month (to end of November).
    • ST-E is currently refactoring their Xorg drivers so that they can open source a part of it, waiting for ARM confirmation.
