Agenda

  • Welcome
  • previous actions status review
  • status update on texture pixmap
  • clutter/unity archive update
  • review linaro graphics WG topics for next cycle
  • camera-bin status

Minutes

  • EGL Video Rendering (Sachin)
    • More work to happen this week
  • camera-bin (Sachin, Rob)
    • Sachin in contact with Rob about camera-bin.
    • Questions mostly answered.
    • camera-bin still not inserting thumbnails.
  • gst-openmax consolidation (Rob)
    • Code is in public git repository.
    • Tested only on omap4.
    • gst-dsp is a better choice for omap3.
    • ACTION: Rob to send link to gst-openmax git repository and give a summary of the changes.
  • omap3/4 gfx packages (Ricardo)
    • Target is to push to multiverse (still in private PPA)
    • Packages depend on linux header or linaro headers to be compatible with Linaro kernel.
    • Have issue with mesa -dev packages that are needed to build applications.
    • sgx GL libs have different soname than Mesa libs, so we can't build against them.
    • omap4 packages currently copy omap3 packages (Vincent)
      • Have same soname issues as omap3
      • IMG makefiles are complicated to fix, but this seems to be the best way to alter SONAME.
      • TI-IMG interaction mainly through bugs/tickets.
      • ACTION:Alexander to establish connection with Meego folks so we can jointly solve the sgx driver SONAME issue.

  • Split call (Alexander)
    • From next week (Oct 4th-) call is going to be split in graphics and multimedia parts.
    • Graphics call: Every Monday 12:00 UTC .
    • Multimedia call: Every Tuesday 12:00 UTC .
  • Xorg consolidated driver
    • Make xorg driver with plugin architecture so it can accommodate different HW.
    • Base on Mali driver?
      • Perhaps not enough code is going to be released to be useful as a base to build on.
      • ACTION: Bring up driver release issue on Mali call.
    • gallium3D
      • The right way to go in the future
      • Maybe not enough performance (yet). But good place for the work to happen.
      • Vendors need to release GPU drivers for Gallium for this to be useful.
  • Kernel improvements
    • drm for non-pci
      • there was a pull that perhaps included these changes
      • Need to check
    • drm MM (memory management) standard
      • We need a set of interface to abstract details of MM used (GEM, TTM...)
      • Preferably work with upstream drm developers
      • ACTION: Jesse to initiate discussion on drm mm issue with upstream.
  • clutter, mutter, clutk. (Jammy, Alexandros)
    • Not fully working stack yet ...
    • ...but mutter and clutk now work on freescale/imx51 (with freescale gfx drivers)!
    • Progress done on clutk thanks to Jammy.
    • Mutter on beagleboard has issues
      • With Mesa only part of the screen drawn and mouse input is "a bit scaled" (vertical & horizontal).

      • SGX driver does segmentation faults.
      • Many things fixed in new clutter (according to upstream) but clutk not full tested on clutter 1.4.
  • Gfx libraries optimization
    • Skia has NEON support but hasn't got NEON runtime detection.
    • Pixman supports NEON runtime detection.
      • Should look at it as a base for ideas for a general purpose NEON optimization library.

Actions

  • Rob to send link to gst-openmax git repository and give a summary of the changes.
  • Alexander to establish connection with Meego folks so we can jointly solve the sgx driver SONAME issue.
  • Bring up driver release issue on Mali call.
  • Jesse to initiate discussion on drm mm issue with upstream.
