Hi,
I'm trying to rewrite my DirectFB 1.4.2 driver to make it work with
multiple processes. It's going well, but it's not clear to me exactly
what layer functions are required in the slave processes. It is my
understanding that the master is the one who configures the hardware;
the slaves shouldn't even touch the layer configuration. Is it legal for
the slaves to configure layers themselves? SaWMan seems to be doing
precisely that.
If I don't implement any layer functions in the slave (just set NULL
pointers for every function) will it work? Is it even correct?
Thanks,
Sorin
