From fdb59f927ee739bbda9db671e11bf83d5a3143f3 Mon Sep 17 00:00:00 2001 From: jkoshy Date: Sun, 9 Nov 2008 17:37:54 +0000 Subject: - Separate PMC class dependent code from other kinds of machine dependencies. A 'struct pmc_classdep' structure describes operations on PMCs; 'struct pmc_mdep' contains one or more 'struct pmc_classdep' structures depending on the CPU in question. Inside PMC class dependent code, row indices are relative to the PMCs supported by the PMC class; MI code in "hwpmc_mod.c" translates global row indices before invoking class dependent operations. - Augment the OP_GETCPUINFO request with the number of PMCs present in a PMC class. - Move code common to Intel CPUs to file "hwpmc_intel.c". - Move TSC handling to file "hwpmc_tsc.c". --- sys/dev/hwpmc/hwpmc_tsc.h | 43 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 sys/dev/hwpmc/hwpmc_tsc.h (limited to 'sys/dev/hwpmc/hwpmc_tsc.h') diff --git a/sys/dev/hwpmc/hwpmc_tsc.h b/sys/dev/hwpmc/hwpmc_tsc.h new file mode 100644 index 0000000..a8b011e --- /dev/null +++ b/sys/dev/hwpmc/hwpmc_tsc.h @@ -0,0 +1,43 @@ +/*- + * Copyright (c) 2008 Joseph Koshy + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
