Hello, FYI: don't use the oprofile tools tarball - use the latest from the CVS site on sourceforge. The last tarball on the website is more than a bit out of date. I'll follow up on your other questions in a separate email (in a little while....). /Mark > > #1: I looked at oprofile-0.9.1 and it lists this event for SB1 in the > events/mips/sb1 directory > -------------------------------------------------------------- > ---------- > --- > event:10 counters:1,2,3 um:zero minimum:500 > name:DCACHE_FILLED_SHD_NONC_EXC :Dcache is filled (shared, nonc, > exclusive) > ---------------------------------------------------------------- > > However this doesn't have an equivalent performance source > Listed in the sibyte manual (table 33 system performance > counter sources). Are you looking in Sb1-UM100-RDS.pdf? This is in table 95 in my copy, on page 96/97 (section 11). Also note that the table isn't in order -- event #10 appears on the top of the 2nd page. It's logical grouping, not numeric. > #2: how does the mapping from event numbers to performance > sources work for sibyte ? > > I looked at the op_model_mipsxx.c file in the 2.6 CVS tree > and the macro it uses doesn't seem to match the format > specified for perf_cnt_cfg register in sibyte. Are you using the kernel from CVS instead of git? The SB1 oprofile support didn't turn up in the kernel until sometime mid-January, and is only available through the git version (the CVS version of the kernel is long out of date). HTH, Mark
