Optionally install libnuma-devel but the test will cope if it's not available. Automatic package installation will be in 0.06 for opensuse at least but other distros can be easily supported if I know the names of the equivalent packages. The above command will run both with and without profiling. The profiles will be in work/log/pft-testrun/fine-profile-timer/base/ and an annotated profile will be included in the file. If you have "recode" installed the annotated profile will be compressed and can be extracted with something like grep -A 9999999 "=== annotate ===" oprofile-compressed.report | grep -v annotate | recode /b64..char | gunzip -c Each of the memcg functions will be small but when all the functions that are in mm/memcontrol.c are added together it becomes a big problem. What I actually showed at the meeting was based on piping the oprofile report through another quick and dirty script to match functions to filenames. The bulk of this patch is renaming profile-disabled-hooks-a.sh to profile-hooks-a.sh. Let me know if you run into problems. ---8<-- mmtests: Configure for PFT profile Signed-off-by: Mel Gorman <mgorman@...e.de> diff --git a/config b/config index 184864f..e1afb2a 100644 --- a/config +++ b/config @@ -9,9 +9,9 @@ export SKIP_WARMUP=yes # Profiling parameters export SKIP_NOPROFILE=no -export SKIP_FINEPROFILE=yes +export SKIP_FINEPROFILE=no export SKIP_COARSEPROFILE=yes -export OPROFILE_REPORT_ANNOTATE=no +export OPROFILE_REPORT_ANNOTATE=yes # Fixups if [ "`which check-confidence.pl 2> /dev/null`" = "" ]; then @@ -57,7 +57,7 @@ export SWAP_NBD_PORT=100`ifconfig eth0 | sed -n 2p | cut -d ":" -f2 | cut -d " " #export TESTDISK_NBD_PORT=100`ifconfig eth0 | sed -n 2p | cut -d ":" -f2 | cut -d " " -f1 | cut -d "." -f4` # List of monitors -export RUN_MONITOR=yes +export RUN_MONITOR=no export MONITORS_ALWAYS= export MONITORS_PLAIN= export MONITORS_GZIP="proc-vmstat top slabinfo" diff --git a/profile-disabled-hooks-a.sh b/profile-disabled-hooks-a.sh deleted file mode 100644 index c953dff..0000000 --- a/profile-disabled-hooks-a.sh +++ /dev/null @@ -1,48 +0,0 @@ -if [ "$SAMPLE_CYCLE_FACTOR" = "" ]; then - SAMPLE_CYCLE_FACTOR=1 -fi - -CALLGRAPH=0 -if [ "$OPROFILE_REPORT_CALLGRAPH" != "" ]; then - CALLGRAPH=$OPROFILE_REPORT_CALLGRAPH - if [ $SAMPLE_CYCLE_FACTOR -lt 15 ]; then - SAMPLE_CYCLE_FACTOR=15 - fi -fi - -# Create profiling hooks -PROFILE_TITLE="timer" - -echo "#!/bin/bash" > monitor-pre-hook -case `uname -m` in - i?86) - echo "oprofile_start.sh --callgraph $CALLGRAPH --sample-cycle-factor $SAMPLE_CYCLE_FACTOR --event timer" >> monitor-pre-hook - export PROFILE_EVENTS=timer - ;; - x86_64) - echo "oprofile_start.sh --callgraph $CALLGRAPH --sample-cycle-factor $SAMPLE_CYCLE_FACTOR --event timer" >> monitor-pre-hook - export PROFILE_EVENTS=timer - ;; - ppc64) - echo "oprofile_start.sh --callgraph $CALLGRAPH --sample-cycle-factor $SAMPLE_CYCLE_FACTOR --event timer" >> monitor-pre-hook - export PROFILE_EVENTS=timer - ;; - *) - echo Unrecognised architecture - exit -1 - ;; -esac - -echo "#!/bin/bash" > monitor-post-hook -echo "opcontrol --dump" >> monitor-post-hook -echo "opcontrol --stop" >> monitor-post-hook -echo "oprofile_report.sh > \$1/oprofile-\$2-report-$PROFILE_TITLE.txt" >> monitor-post-hook - -echo "#!/bin/bash" > monitor-cleanup-hook -echo "rm \$1/oprofile-\$2-report-$PROFILE_TITLE.txt" >> monitor-cleanup-hook - -echo "#!/bin/bash" > monitor-reset -echo "opcontrol --stop > /dev/null 2> /dev/null" >> monitor-reset -echo "opcontrol --deinit > /dev/null 2> /dev/null" >> monitor-reset - -chmod u+x monitor-* diff --git a/profile-hooks-a.sh b/profile-hooks-a.sh new file mode 100644 index 0000000..c953dff --- /dev/null +++ b/profile-hooks-a.sh @@ -0,0 +1,48 @@ +if [ "$SAMPLE_CYCLE_FACTOR" = "" ]; then + SAMPLE_CYCLE_FACTOR=1 +fi + +CALLGRAPH=0 +if [ "$OPROFILE_REPORT_CALLGRAPH" != "" ]; then + CALLGRAPH=$OPROFILE_REPORT_CALLGRAPH + if [ $SAMPLE_CYCLE_FACTOR -lt 15 ]; then + SAMPLE_CYCLE_FACTOR=15 + fi +fi + +# Create profiling hooks +PROFILE_TITLE="timer" + +echo "#!/bin/bash" > monitor-pre-hook +case `uname -m` in + i?86) + echo "oprofile_start.sh --callgraph $CALLGRAPH --sample-cycle-factor $SAMPLE_CYCLE_FACTOR --event timer" >> monitor-pre-hook + export PROFILE_EVENTS=timer + ;; + x86_64) + echo "oprofile_start.sh --callgraph $CALLGRAPH --sample-cycle-factor $SAMPLE_CYCLE_FACTOR --event timer" >> monitor-pre-hook + export PROFILE_EVENTS=timer + ;; + ppc64) + echo "oprofile_start.sh --callgraph $CALLGRAPH --sample-cycle-factor $SAMPLE_CYCLE_FACTOR --event timer" >> monitor-pre-hook + export PROFILE_EVENTS=timer + ;; + *) + echo Unrecognised architecture + exit -1 + ;; +esac + +echo "#!/bin/bash" > monitor-post-hook +echo "opcontrol --dump" >> monitor-post-hook +echo "opcontrol --stop" >> monitor-post-hook +echo "oprofile_report.sh > \$1/oprofile-\$2-report-$PROFILE_TITLE.txt" >> monitor-post-hook + +echo "#!/bin/bash" > monitor-cleanup-hook +echo "rm \$1/oprofile-\$2-report-$PROFILE_TITLE.txt" >> monitor-cleanup-hook + +echo "#!/bin/bash" > monitor-reset +echo "opcontrol --stop > /dev/null 2> /dev/null" >> monitor-reset +echo "opcontrol --deinit > /dev/null 2> /dev/null" >> monitor-reset + +chmod u+x monitor-* -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
