-FFmpeg & evaluating performance on the PowerPC Architecture HOWTO
-
-(c) 2003-2004 Romain Dolbeau <romain@dolbeau.org>
-
-
-
-I - Introduction
-
-The PowerPC architecture and its SIMD extension AltiVec offer some
-interesting tools to evaluate performance and improve the code.
-This document tries to explain how to use those tools with FFmpeg.
-
-The architecture itself offers two ways to evaluate the performance of
-a given piece of code:
-
-1) The Time Base Registers (TBL)
-2) The Performance Monitor Counter Registers (PMC)
-
-The first ones are always available, always active, but they're not very
-accurate: the registers increment by one every four *bus* cycles. On
-my 667 Mhz tiBook (ppc7450), this means once every twenty *processor*
-cycles. So we won't use that.
-
-The PMC are much more useful: not only can they report cycle-accurate
-timing, but they can also be used to monitor many other parameters,
-such as the number of AltiVec stalls for every kind of instruction,
-or instruction cache misses. The downside is that not all processors
-support the PMC (all G3, all G4 and the 970 do support them), and
-they're inactive by default - you need to activate them with a
-dedicated tool. Also, the number of available PMC depends on the
-procesor: the various 604 have 2, the various 75x (aka. G3) have 4,
-and the various 74xx (aka G4) have 6.
-
-*WARNING*: The PowerPC 970 is not very well documented, and its PMC
-registers are 64 bits wide. To properly notify the code, you *must*
-tune for the 970 (using --tune=970), or the code will assume 32 bit
-registers.
-
-
-II - Enabling FFmpeg PowerPC performance support
-
-This needs to be done by hand. First, you need to configure FFmpeg as
-usual, but add the "--powerpc-perf-enable" option. For instance:
-
-#####
-./configure --prefix=/usr/local/ffmpeg-svn --cc=gcc-3.3 --tune=7450 --powerpc-perf-enable
-#####
-
-This will configure FFmpeg to install inside /usr/local/ffmpeg-svn,
-compiling with gcc-3.3 (you should try to use this one or a newer
-gcc), and tuning for the PowerPC 7450 (i.e. the newer G4; as a rule of
-thumb, those at 550Mhz and more). It will also enable the PMC.
-
-You may also edit the file "config.h" to enable the following line:
-
-#####
-// #define ALTIVEC_USE_REFERENCE_C_CODE 1
-#####
-
-If you enable this line, then the code will not make use of AltiVec,
-but will use the reference C code instead. This is useful to compare
-performance between two versions of the code.
-
-Also, the number of enabled PMC is defined in "libavcodec/ppc/dsputil_ppc.h":
-
-#####
-#define POWERPC_NUM_PMC_ENABLED 4
-#####
-
-If you have a G4 CPU, you can enable all 6 PMC. DO NOT enable more
-PMC than available on your CPU!
-
-Then, simply compile FFmpeg as usual (make && make install).
-
-
-
-III - Using FFmpeg PowerPC performance support
-
-This FFmeg can be used exactly as usual. But before exiting, FFmpeg
-will dump a per-function report that looks like this:
-
-#####
-PowerPC performance report
- Values are from the PMC registers, and represent whatever the
- registers are set to record.
- Function "gmc1_altivec" (pmc1):
- min: 231
- max: 1339867
- avg: 558.25 (255302)
- Function "gmc1_altivec" (pmc2):
- min: 93
- max: 2164
- avg: 267.31 (255302)
- Function "gmc1_altivec" (pmc3):
- min: 72
- max: 1987
- avg: 276.20 (255302)
-(...)
-#####
-
-In this example, PMC1 was set to record CPU cycles, PMC2 was set to
-record AltiVec Permute Stall Cycles, and PMC3 was set to record AltiVec
-Issue Stalls.
-
-The function "gmc1_altivec" was monitored 255302 times, and the
-minimum execution time was 231 processor cycles. The max and average
-aren't much use, as it's very likely the OS interrupted execution for
-reasons of its own :-(
-
-With the exact same settings and source file, but using the reference C
-code we get:
-
-#####
-PowerPC performance report
- Values are from the PMC registers, and represent whatever the
- registers are set to record.
- Function "gmc1_altivec" (pmc1):
- min: 592
- max: 2532235
- avg: 962.88 (255302)
- Function "gmc1_altivec" (pmc2):
- min: 0
- max: 33
- avg: 0.00 (255302)
- Function "gmc1_altivec" (pmc3):
- min: 0
- max: 350
- avg: 0.03 (255302)
-(...)
-#####
-
-592 cycles, so the fastest AltiVec execution is about 2.5x faster than
-the fastest C execution in this example. It's not perfect but it's not
-bad (well I wrote this function so I can't say otherwise :-).
-
-Once you have that kind of report, you can try to improve things by
-finding what goes wrong and fixing it; in the example above, one
-should try to diminish the number of AltiVec stalls, as this *may*
-improve performance.
-
-
-
-IV) Enabling the PMC in Mac OS X
-
-This is easy. Use "Monster" and "monster". Those tools come from
-Apple's CHUD package, and can be found hidden in the developer web
-site & FTP site. "MONster" is the graphical application, use it to
-generate a config file specifying what each register should
-monitor. Then use the command-line application "monster" to use that
-config file, and enjoy the results.
-
-Note that "MONster" can be used for many other things, but it's
-documented by Apple, it's not my subject.
-
-If you are using CHUD 4.4.2 or later, you'll notice that MONster is
-no longer available. It's been superseeded by Shark, where
-configuration of PMCs is available as a plugin.
-
-
-
-V) Enabling the PMC on Linux
-
-On linux you may use oprofile from http://oprofile.sf.net, depending on the
-version and the cpu you may need to apply a patch[1] to access a set of the
-possibile counters from the userspace application. You can always define them
-using the kernel interface /dev/oprofile/* .
