Modified files: sys/conf files.powerpc sys/powerpc/include pmap.h sys/powerpc/powerpc machdep.c Added files: sys/powerpc/include mmuvar.h sys/powerpc/powerpc mmu_if.m pmap_dispatch.c Log: Insert a layer of indirection to the pmap code, using a kobj for the interface. This allows run-time selection of MMU code, based on CPU-type detection, or tunable-overrides when testing new code. Pre-requisite for G5 support. conf/files.powerpc - remove pmap.c - add mmu_if.h, mmu_oea.c, pmap_dispatch.c powerpc/include/mmuvar.h - definitions for MMU implementations powerpc/include/pmap.h - remove pmap_pte_spill declaration - add pmap_mmu_install declaration - size the phys_avail array - pmap_bootstrapped is now global-scope powerpc/powerpc/machdep.c - call kobj_machdep_init early in the boot sequence to allow kobj usage prior to SI_SUB_LOCK - install the OEA pmap code. This will be moved to CPU-specific init code in the future. powerpc/powerpc/mmu_if.m - Kobj MMU interface definitions powerpc/powerpc/pmap_dispatch.c - central dispatch for pmap calls - contains the global mmu kobj and the routine to locate the the mmu implementation and init the kobj Revision Changes Path 1.45 +3 -1 src/sys/conf/files.powerpc 1.1 +96 -0 src/sys/powerpc/include/mmuvar.h (new) 1.18 +6 -4 src/sys/powerpc/include/pmap.h 1.92 +4 -0 src/sys/powerpc/powerpc/machdep.c 1.1 +758 -0 src/sys/powerpc/powerpc/mmu_if.m (new) 1.1 +380 -0 src/sys/powerpc/powerpc/pmap_dispatch.c (new) _______________________________________________ cvs-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/cvs-all To unsubscribe, send any mail to "[EMAIL PROTECTED]"
