[meta-freescale] Any hope of vblank-synchronized rendering (from vivante) on i.MX6 soon?

[Gerard Bucas]

Thanks Daiane - will do. 

When is the next such meeting and who is actually the interface with Vivante that could put some pressure on them!?

DRI2 is used all over in the X11 code according to this so I think this is a critical area to solve the serious shortcomings and performance in the current X11 port on the I.MX6. See: http://en.m.wikipedia.org/wiki/DRI2 for more details.
