Hi,
notes and actions from our Wednesday graphics working group call are available on the wiki:
+ https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/Notes/2011-02-09
Details about when and where of this meeting can be found here:
+ https://wiki.linaro.org/WorkingGroups/Middleware/Graphics#Weekly%20Public%20...
Summary =======
* Cairo patchset "gl: Replace built-in shader variables with custom variables" sent upstream for review. * Most of the team members able to access git.linaro.org from work place but not confirmed for everyone. * Added desktop GL support to glcompbench benchmark, in order to promote adoption and increase contributions and feedback. * Qtwebkit investigation shows that trace captures for websites (without <canvas>) can be performed without pixmap tracing. * Refactored most core Compiz plugins to make them GLES2 ready. * First experiments adding Mali(ARM's GPU) and UMP driver to Linaro kernel are ongoing. Bugs have been discovered and are being worked on with Samsung landing team. * First version of Unified Memory Management position: https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/Projects/UnifiedMe...
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 their blueprints and fix any pending issues. * Everyone to update blueprints to reflect current work item status.
Thanks,

btw, the access control aspect of this sort of reminds me of the DRM driver infrastructure, and authentication between direct rendering client and x-server (or whoever the DRM master is)..
I wonder if there is, or should be, a connection..

Rob,
It is certainly analogous to the DRM access control interfaces, and I would expect that access to memory objects from the graphics stack would go through those interfaces (i.e. Xorg/EGL calls libdrm, calls DRM kernel ioctl, calls memory manger inside the kernel), but we need to make sure we have equivalent interfaces setup for non-graphics applications to make sure that all access control policy is honored. So, in short, yes, there's a connection :-).
cheers, Jesse
