Revision ca71ba4d0cfcf5f7a8e9b24339547b5a72299f80 authored by John Baldwin on 26 January 2010, 20:58:09 UTC, committed by John Baldwin on 26 January 2010, 20:58:09 UTC
Optimize the cache flushing done when changing caching attributes of pages by doing nothing for CPUs that support self-snooping and using CLFLUSH instead of a full cache invalidate when possible. - On i386 take care of possible mappings of the page by sf buffer by utilizing the mapping for clflush, otherwise map the page transiently. Amd64 uses the direct map. - Do not use CLFLUSH on Intel CPUs due to problems with flushing the local APIC range by default. This can be further controlled via the hw.clflush_disable loader tunable. A setting of 1 disables the use of CLFLUSH. A setting of 0 allows CLFLUSH to be used for Intel CPUs when CPUID_SS is not present. Approved by: re (kib)
