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
