Modified Files: src/sys/external/bsd/drm2/include/linux [netbsd-7]: io-mapping.h Log Message: Pull up following revision(s) (requested by riastradh in ticket #98): sys/external/bsd/drm2/include/linux/io-mapping.h: revision 1.3 Make Linux io_mapping actually work. Can't use bus_space_map/bus_space_unmap in interrupt context, where Linux uses this io_mapping abstraction. Instead, do uvm_km_alloc up front and then use bus_space_mmap/pmap_kenter_pa to map it. XXX Should bus_space_reserve the region (but that's x86-only for now). XXX Should use direct map if possible. XXX Should set an MTRR WC too in case of direct map or no PAT.
