Marius Strobl bda8e754a1 Make sparc64 compatible with NEW_PCIB and enable it: ... - Implement bus_adjust_resource() methods as far as necessary and in non-PCI bridge drivers as far as feasible without rototilling them. - As NEW_PCIB does a layering violation by activating resources at layers above pci(4) without previously bubbling up their allocation there, move the assignment of bus tags and handles from the bus_alloc_resource() to the bus_activate_resource() methods like at least the other NEW_PCIB enabled architectures do. This is somewhat unfortunate as previously sparc64 (ab)used resource activation to indicate whether SYS_RES_MEMORY resources should be mapped into KVA, which is only necessary if their going to be accessed via the pointer returned from rman_get_virtual() but not for bus_space(9) as the later always uses physical access on sparc64. Besides wasting KVA if we always map in SYS_RES_MEMORY resources, a driver also may deliberately not map them in if the firmware already has done so, possibly in a special way. So in order to still allow a driver to decide whether a SYS_RES_MEMORY resource should be mapped into KVA we let it indicate that by calling bus_space_map(9) with BUS_SPACE_MAP_LINEAR as actually documented in the bus_space(9) page. This is implemented by allocating a separate bus tag per SYS_RES_MEMORY resource and passing the resource via the previously unused bus tag cookie so we later on can call rman_set_virtual() in sparc64_bus_mem_map(). As a side effect this now also allows to actually indicate that a SYS_RES_MEMORY resource should be mapped in as cacheable and/or read-only via BUS_SPACE_MAP_CACHEABLE and BUS_SPACE_MAP_READONLY respectively. - Do some minor cleanup like taking advantage of rman_init_from_resource(), factor out the common part of bus tag allocation into a newly added sparc64_alloc_bus_tag(), hook up some missing newbus methods and replace some homegrown versions with the generic counterparts etc. - While at it, let apb_attach() (which can't use the generic NEW_PCIB code as APB bridges just don't have the base and limit registers implemented) regarding the config space registers cached in pcib_softc and the SYSCTL reporting nodes set up.		2011-10-02 23:22:38 +00:00
