Hi, I wonder if OpenSolaris is providing an API to control memory caching on x86? Clearly the AMD64 ISA covers this (global cache enable/disable, WBINVD, memory-type range registers (MTRRs), page-attribute table (PAT)). But is any of this available to user applications? man mmap does not give any hint.
I found however the following entry at http://jp.opensolaris.org/os/community/arc/caselog/2006/188/ --------------------------------------------------- Memory Cache Disable Support on x86 PSARC 2006/188 (Approved FastTrack) Submitted 21 March 2006 Status closed approved fast-track 4/5/2006 Duration 15 Days Submitter Eiji Ota Case Owner Shudong Zhou Case Materials Exposure: manual Case Event Log Date Event Comment 21 Mar 2006 CreatedFastTrack 21 Mar 2006 Associated 20060321_eiji.ota PSARC/2006/188 22 Mar 2006 New SACProject 2006/188 PSARC waiting fast-track 3/28/2006 22 Mar 2006 New Project 2006/188 03/21/2006 Memory Cache Disable Support on x86 30 Mar 2006 New Status waiting fast-track 4/4/2006 6 Apr 2006 New Status closed approved fast-track 4/5/2006 --------------------------------------------------- Thanks, Manfred -- This message posted from opensolaris.org _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
