Perf cannot parse UPI (Intel's "Ultra Path Interconnect" [1]) events. # perf stat -e UPI_DATA_BANDWIDTH_TX event syntax error: 'UPI_DATA_BANDWIDTH_TX' \___ parser error Run 'perf list' for a list of valid events The JSON lists call the box UPI LL, while perf calls it upi. Add conversion support to JSON to convert the unit properly. Committer notes: [1] https://en.wikipedia.org/wiki/Intel_Ultra_Path_Interconnect "The Intel Ultra Path Interconnect (UPI) is a point-to-point processor interconnect developed by Intel which replaced the Intel QuickPath Interconnect (QPI) in Xeon Skylake-SP platforms starting in 2017. UPI is a low-latency coherent interconnect for scalable multiprocessor systems with a shared address space. It uses a directory-based home snoop coherency protocol with a transfer speed of up to 10.4 GT/s. Supporting processors typically have two or three UPI links."

When compiled with libunwind, perf does some preparatory work when processing side-band events. This is not needed when report actually don't unwind dwarf callchains, so it's disabled with dwarf_callchain_users bool. However we could move that check to higher level and shield more unwanted code for normal report processing, giving us following speed up on kernel build profile: Before: $ perf record make -j40 ... $ ll ../../perf.data -rw-------. 1 jolsa jolsa 461783932 Apr 26 09:11 perf.data $ perf stat -e cycles:u,instructions:u perf report -i perf.data > out Performance counter stats for 'perf report -i perf.data': 78,669,920,155 cycles:u 99,076,431,951 instructions:u # 1.26 insn per cycle 55.382823668 seconds time elapsed 27.512341000 seconds user 27.712871000 seconds sys After: $ perf stat -e cycles:u,instructions:u perf report -i perf.data > out Performance counter stats for 'perf report -i perf.data': 59,626,798,904 cycles:u 88,583,575,849 instructions:u # 1.49 insn per cycle 21.296935559 seconds time elapsed 20.010191000 seconds user 1.202935000 seconds sys The speed is higher with profile having many side-band events, because these trigger libunwind preparatory code.

The hist__account_cycles() function is executed when the hist_iter__branch_callback() is called. But it looks it's not necessary. In hist__account_cycles, it already walks on all branch entries. This patch moves the hist__account_cycles out of callback, now the data processing is much faster than before. Previous code has an issue that the ch[offset].num++ (in __symbol__account_cycles) is executed repeatedly since hist__account_cycles is called in each hist_iter__branch_callback, so the counting of ch[offset].num is not correct (too big). With this patch, the issue is fixed. And we don't need the code of "ch->reset >= ch->num / 2" to check if there are too many overlaps (in annotation__count_and_fill), otherwise some data would be hidden. Now, we can try, for example: perf record -b ... perf annotate or perf report -s symbol The before/after output should be no change. v3: --- Fix the crash in stdio mode. Like previous code, it needs the checking of ui__has_annotation() before hist__account_cycles() v2: --- 1. Cover the similar perf report 2. Remove the checking code "ch->reset >= ch->num / 2" Signed-off-by:

On Intel Westmere, a cmdline as follows: $ perf record -e cpu/event=0xc4,umask=0x2,name=br_inst_retired.near_call/p .... was failing. Yet the event+ umask support PEBS. It turns out this is due to a bug in the the PEBS event constraint table for westmere. All forms of BR_INST_RETIRED.* support PEBS. Therefore the constraint mask should ignore the umask. The name of the macro INTEL_FLAGS_EVENT_CONSTRAINT() hint that this is the case but it was not. That macros was checking both the event code and event umask. Therefore, it was only matching on 0x00c4. There are code+umask macros, they all have *UEVENT*. This bug fixes the issue by checking only the event code in the mask. Both single and range version are modified. Signed-off-by:
