Hi, After checking the data range restriction example included with the library (mont_rr.c, in the old_interface_ia64_examples directory) I've been trying to modify it to cover two different data ranges. The example has two arrays already defined: test_data and test_data_fake. I define a third one, test_data_fake2, and I get the start and end ranges, as done for test_data:
test_data_fake2 = (test_data_t*)malloc(sizeof(test_data_t)*TEST_DATA_COUNT); range_start_fake2 = (unsigned long)test_data_fake2; range_end_fake2 = range_start_fake2 + \ sizeof(test_data_t)*TEST_DATA_COUNT; Afterwards, I try to use a pair of debug registers to cover this new array: mont_inp.pfp_mont_drange.rr_limits[1].rr_start = range_start_fake2; mont_inp.pfp_mont_drange.rr_limits[1].rr_end = range_end_fake2; but I get an error message when I run the code: "cannot configure events: too many data ranges". Using the next pair (rr_limits[2]) I don't get any error, but I got the following output: [PMC5(pmc5)=0x200ce08 m=0 e=0 s=0 i=0 thres=0 all=0 es=0xce plm=8 umask=0x0 pm=0 ism=0x2 oi=0] MISALIGNED_LOADS_RETIRED [PMD5(pmd5)] [0x6000000000004010-0x6000000000004110): 4 register pair(s) start offset: -0x10 end_offset: +0x0 brp0: db0: 0x6000000000004080 db1: plm=0x8 mask=0x00ffffffffffff80 end=0x60000000000040ff brp1: db2: 0x6000000000004040 db3: plm=0x8 mask=0x00ffffffffffffc0 end=0x600000000000407f brp2: db4: 0x6000000000004000 db5: plm=0x8 mask=0x00ffffffffffffc0 end=0x600000000000403f brp3: db6: 0x6000000000004100 db7: plm=0x8 mask=0x00fffffffffffff0 end=0x600000000000410f [PMC41(pmc41)=0x1e078f6f6f6f6 cfg_dtag0=2 cfg_dtag1=2 cfg_dtag2=2 cfg_dtag3=2 ena_dbrp0=1 ena_dbrp1=1 ena_dbrp2=1 ena_dbrp3=1] data range : [0x6000000000004010-0x6000000000004110): 4 pair of debug registers used start_offset:-0x10 end_offset:+0x0 Fake data range2 : [0x6000000000004230-0x6000000000004330) start_offset:-0x0 end_offset:+0x0 fake data range: [0x6000000000004120-0x6000000000004220) So it looks the test_data_fake2 is in the range (0x60...4230,0x60...4330), but the debug registers (db0-db7) only show coverage from addresses 0x6...4080 to 0x6...410f. Any hint of what's wrong? Isn't it possible to cover two data ranges at the same time in Montecito/Montvale?. Perfmon2 documentation says that "Up to 4 ranges can be defined" in Montecito.
