It is just a small optimization, userspace can skip the LRU lookup altogether if the generation didn't change. But of couse that only pays off if the kernel doesn't has to put much effort into maintaining the generation id. Something simple like increasing it each time the guest writes a register which affects plane_info. If you think it doesn't make sense from the driver point of view we can drop the generation. cheers, Gerd _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
