\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.
