\brief This file provides macros to profile your code.
Here's how they work...
As you may or may not know, the Pentium class of
processors provides extremely fine grained profiling
capabilities through the use of what are called
Machine Specific Registers (MSRs). These registers
can provide information about almost any aspect of
CPU performance down to a single cycle.
The MSRs of interest for profiling are specified by
indices 0x10, 0x11, 0x12, and 0x13. Here is a brief
description of each of these registers:
MSR 0x10
This register is simple a cycle counter.
MSR 0x11
This register controls what type of profiling data
will be gathered.
MSRs 0x12 and 0x13
These registers gather the profiling data specified in
MSR 0x11.
Each MSR is 64 bits wide. For the Pentium processor,
only the lower 32 bits of MSR 0x11 are valid. Bits 0-15
specify what data will be gathered in MSR 0x12. Bits 16-31
specify what data will be gathered in MSR 0x13. Both sets
of bits have the same format:
Bits 0-5 specify which hardware event will be tracked.
Bit 6, if set, indicates events will be tracked in
rings 0-2.
Bit 7, if set, indicates events will be tracked in
ring 3.
Bit 8, if set, indicates cycles should be counted for
the specified event. If clear, it indicates the
number of events should be counted.
Two instructions are provided for manupulating the MSRs.
RDMSR (Read Machine Specific Register) and WRMSR
(Write Machine Specific Register). These opcodes were
originally undocumented and therefore most assemblers don't
recognize them. Their byte codes are provided in the
macros below.
RDMSR takes the MSR index in ecx and the profiling criteria
in edx : eax.
WRMSR takes the MSR index in ecx and returns the profile data
in edx : eax.
Two profiling registers limits profiling capability to
gathering only two types of information. The register
usage can, however, be combined in interesting ways.
For example, you can set one register to gather the
number of a specific type of event while the other gathers
the number of cycles for the same event. Or you can
gather the number of two separate events while using
MSR 0x10 to gather the number of cycles.
The enumerated list provides somewhat readable labels for
the types of events that can be tracked.
For more information, get ahold of appendix H from the
Intel Pentium programmer's manual (I don't remember the
order number) or go to
http://green.kaist.ac.kr/jwhahn/art3.htm.
That's an article by Terje Mathisen where I got most of
my information.
You may use this code however you wish. I hope it's
useful and I hope I got everything right.
