MATH_EMULATE opt_math_emulate.h
GPL_MATH_EMULATE opt_math_emulate.h
Revive backed out pmap related changes from Feb 2002. The highlights are: - It actually works this time, honest! - Fine grained TLB shootdowns for SMP on i386. IPI's are very expensive, so try and optimize things where possible. - Introduce ranged shootdowns that can be done as a single IPI. - PG_G support for i386 - Specific-cpu targeted shootdowns. For example, there is no sense in globally purging the TLB cache for where we are stealing a page from the local unshared process on the local cpu. Use pm_active to track this. - Add some instrumentation for the tlb shootdown code. - Rip out SMP code from <machine/cpufunc.h> - Try and fix some very bogus PG_G and PG_PS interactions that were bad enough to cause vm86 bios calls to break. vm86 depended on our existing bugs and this was the cause of the VESA panics last time. - Fix the silly one-line error that caused the 'panic: bad pte' last time. - Fix a couple of other silly one-line errors that should have caused more pain than they did. Some more work is needed: - pmap_{zero,copy}_page[_idle]. These can be done without IPI's if we have a hook in cpu_switch. - The IPI handlers need some cleanup. I have a bogus %ds load that can be avoided. - APTD handling is rather bogus and appears to be a large source of global TLB IPI shootdowns for no really good reason. I see speedups of between 1.5% and ~4% on buildworlds in a while 1 loop. I expect to see a bigger difference when there is significant pageout activity or the system otherwise has memory shortages. I have backed out a few optimizations that I had been using over the last few days in order to be a little more conservative. I'll revisit these again over the next few days as the dust settles. New option: DISABLE_PG_G - In case I missed something.
