This alarmed me; I don't want to see VIAs problem become a DRM wide=20 rule. But it seems as if this alignment is enforced only through the device=20 specific code (xxx_mm.c), and that there really is nothing to worry=20 about. Has me wondering though; Why does sis_mm.c enforce the same alignment?=20 Is this just a safe value? Why does this need to be overridden? Do some=20 engines on some sis hardware require wider alignment, while normal=20 alignment needs to be 16 bytes? Anyway, that's driver specific, not set in stone. Nice work, Luc Verhaegen. |
