\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.
