Hi!
If one were to consider "borrowing" a Unichrome texture unit for Xv, is there some sort of locking mechanism or is the texture source address and stride accompanied with each command buffer it is used?
Just check/set the ctxOwner value in the sarea when X touches the 3d hardware. If the value is unchanged since you set it last time, the hardware is still yours, otherwise you need to restore all state except texture images. Have a look in via_context.c at viaGetLock(). Note this is only called on contended locks.
Ah, thanks. The new Unichrome Pros have two nice fast video processors that can color transform and scale to some degree as part of a blitting stage. For step-less down-scaling it might need some help.
