Action Items

  • Chunsang and Jesse to discuss UMP validation situation and its implications.
  • Jesse to ensure that we have valid conference call numbers for all members of the gfx WG (deferred from previous meeting).
  • Jesse to keep track of nux licensing issues (deferred from previous meeting).
  • Everyone to send Jesse a list of the licenses of the projects they are working on (both new and existing).
  • Everyone to review Rajeev's comments in blueprints and fix any pending issues.
  • Everyone to update blueprints to reflect current work item status (eg mark done items as DONE)

Minutes

  • Team member status reports
    • Fill them in at least 2 hours before the meeting, so that we get a chance to go over them before the meeting starts.
  • DRI/Mali (Chunsang)
    • Started first experiment adding UMP to Linaro (kernel + userspace components)
      • Working with Samsuing Landing team to resolve issues.
    • UMP will not be validated until Q3 2011
      • ACTION: Chunsang to discuss with Jesse UMP validation situation
  • Compiz (Travis)
    • Porting of main plugins is in progress.
    • Change of plans to deliver a working GLES2 version sooner
      • Start porting Compiz core when main plugins have been ported.
      • Don't block on extra plugins, port them afterwards.
      • TI is interested in testing Compiz GLES2
  • Cairo GLES (Alexandros)
    • Waiting for patchset "gl: Replace built-in shader variables with custom variables" to be accepted (or not) upstream.
      • With this patch we are quite close to having GL2/GLES2 compatible source code.
      • Cairo upstream is usually quite fast at reviewing (eg 1 week max).
    • Started working on cairo-egl and uncovered a bug in Mesa.
    • Still need build system changes to allow GL2/GLES2 build time selection.
  • Benchmarks (Alexandros)
    • Added glx and egl-gl support to glcompbench
      • Hope to benefit from greater adoption and feedback
    • Some first (not successful) experiments with pixmap tracing
      • As this is not a blocker we can postpone this for later in the cycle if needed.
      • Difficulty in correlating pixmap and window traces time-wise.
  • Blueprint status (Rajeev)
    • ACTION: Everyone to review Rajeev's comments in their blueprints and fix any pending issues.
    • ACTION: Everyone to update blueprints to reflect current work item status (eg mark done items as DONE)

Complete History

Team Work - Detailed

Alexandros Frantzis (alf)

  • Cairo GLES
  • Benchmarks
    • Added glx and egl-gl support to glcompbench (lp:glcompbench)
    • Continuing investigation on qtwebkit trace
      • Without any changes we can trace everything but <canvas>.

      • Have been experimenting with pixmap traces. It is not a real blocker now (but a nice thing to have).
      • Difficult to combine pixmap and window traces.

Jammy Zhou (jazh)

Chunsang Jeong

  • DRI/Mali
    • Need a further discussion for Mali/DRI implemenation with UMP in 11.05.
      • Mali uses only UMP for X11 implementation up to now and UMP will be verified by ARM and Samsung in 3Q 2011.
    • Finished adding Mali(ARM's GPU) and UMP driver to Linaro kernel.
      • Compiled Mali, UMP user space libraries and 3D sample application by using linaro toochain.
      • FB device open error happened while testing it with 3D sample application.
        • fb device open error happened in eglInitialize, trying to solve this with Samsung landing team.
  • Fixed security problem at work.
    • Fixed IRC problem by using XChat (Got a hint from Patrik Ryd), though still had a problem to access newcore.canonical.com.
    • Can access git.linaro.org

Shariq Hasnain

Travis Watkins (Amaranth)

  • compiz
    • ported most core plugins to use GLVertexBuffer instead of glVertex and friends
      • started porting plugins-main as well, is pretty straightforward except when it's not
    • new idea for handling shaders started, looks good so far, should land this week
    • spent time trying to find cause of decor graphical corruption with these changes, put off for now
