fsmp 1997/08/04 10:31:45 PDT Modified files: sys/i386/include apic.h smptests.h sys/i386/i386 mplock.s swtch.s Log: Eliminate frequent silo overflows by restoring the TEST_LOPRIO code. This code was eliminated when the PEND_INTS algorithm was added. But it was discovered that PEND_INTS only worsen latency for FAST_INTR() routines, which can't be marked pending. Noticed & debugged by: dave adkins <adkin003@gold.tc.umn.edu> Revision Changes Path 1.11 +6 -2 src/sys/i386/include/apic.h 1.19 +7 -1 src/sys/i386/include/smptests.h 1.16 +75 -13 src/sys/i386/i386/mplock.s 1.58 +9 -1 src/sys/i386/i386/swtch.s
