| H A D | pte.h | diff 254918 Mon Aug 26 17:18:51 MDT 2013 raj Introduce superpages support for ARMv6/v7. Promoting base pages to superpages can increase TLB coverage and allow for efficient use of page table entries. This development provides FreeBSD/ARM with superpages management mechanism roughly equivalent to what we have for i386 and amd64 architectures. 1. Add mechanism for automatic promotion of 4KB page mappings to 1MB section mappings (and demotion when not needed, respectively). 2. Managed and non-kernel mappings are now superpages-aware. 3. The functionality can be enabled by setting "vm.pmap.sp_enabled" tunable to a non-zero value (either in loader.conf or by modifying "sp_enabled" variable in pmap-v6.c file). By default, automatic promotion is currently disabled. Submitted by: Zbigniew Bodek <zbb@semihalf.com> Reviewed by: alc Sponsored by: The FreeBSD Foundation, Semihalf |
