How can it be both an integral part of the CPU and board-specific? Either it's under the direct control of the cpu or it's not. If it is, that's cpu-specific and handled by the regular cacheops. If it's not, that's board-specific and is called from a hook into something which the machine detection has set up. > I favor the idea where the cache takes care of external cache dynamically, > based on some parameters set up by board detection routine. So we end up filling the cache routines with tests for board-specific stuff? No way. The cache routines should be dependent ONLY on the CPU - two completely different boards with radically different designs should be able to use the exact same foo-cache.c if they have the same CPU. If it's board-specific we can put generic hooks in but testing for various boards in the cacheops is too expensive and too ugly. -- Keith M Wesolowski <wesolows@foobazco.org> http://foobazco.org/~wesolows ------(( Project Foobazco Coordinator and Network Administrator ))------ "I should have crushed his marketing-addled skull with a fucking bat."
