It is to be displayed in the single cacheline output: node It displays nodes hits related to cacheline accesses. The node filed comes in 3 flavors: - node IDs separated by ',' - node IDs with stats for each ID, in following format: Node{cpus %hitms %stores} - node IDs with list of affected CPUs in following format: Node{cpu list} User can switch the flavor with -N option (-NN,-NNN). It will be available in TUI to switch this with 'n' key. Signed-off-by: -

It is to be displayed in the single cacheline output: pid We currently don't have a single 'pid' sort/display entry, which would output just pid number, hence adding it into c2c code. Signed-off-by:

Adding helping macros to define header objects. It will be used in following patches, that add new dimensions. The c2c report will support 2 line headers, hence we only define line[0/1] in macros. Signed-off-by:

Store cacheline related entries in nested hist object for each cacheline data. Nested entries are sorted by 'offset' within related cacheline. We will allow specific sort keys to be configured for nested cacheline data entries in following patches. Signed-off-by:

Adding basic sample processing specific hist_entry allocation callbacks (via hists__add_entry_ops). Overloading 'struct hist_entry' object with new 'struct c2c_hist_entry'. The new hist entry object will carry specific stats and nested hists objects. Signed-off-by:

Allow to reuse 'struct sort_entry' objects within c2c dimension support. In case the 'struct sort_entry' object meets the need of c2c report we will use it directly in following patches. Signed-off-by:

Adding bare bones of dimension support for c2c report. Main interface functions are: c2c_hists__init c2c_hists__reinit which re/initialize 'struct c2c_hists' object with sort/display entries string, in a similar way that setup_sorting function does. We overload the dimension to provide multi line header support for sort/display entries. Also we overload base 'struct perf_hpp_fmt' object with 'struct c2c_fmt' to define c2c specific functions to deal with multi line headers and spans. Signed-off-by:

Adding c2c record subcommand. It setups options related to HITM cacheline analysis and calls standard perf record command. $ sudo perf c2c record -v -- -a calling: record -W -d --sample-cpu -e cpu/mem-loads,ldlat=30/P -e cpu/mem-stores/P -a ... It produces perf.data, which is to be reported by perf c2c report, that comes in following patches. Details are described in the man page, which is added in one of the following patches. Committer notes: Testing it: # perf c2c record -a sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 5.050 MB perf.data (412 samples) ] # ls -la perf.data -rw-------. 1 root root 5301752 Oct 4 13:32 perf.data # perf evlist cpu/mem-loads,ldlat=30/P cpu/mem-stores/P # perf evlist -v cpu/mem-loads,ldlat=30/P: type: 4, size: 112, config: 0x1cd, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|ADDR|ID|CPU|PERIOD|DATA_SRC|WEIGHT, read_format: ID, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1, task: 1, precise_ip: 3, mmap_data: 1, sample_id_all: 1, mmap2: 1, comm_exec: 1, { bp_addr, config1 }: 0x1f cpu/mem-stores/P: type: 4, size: 112, config: 0x82d0, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|ADDR|ID|CPU|PERIOD|DATA_SRC|WEIGHT, read_format: ID, disabled: 1, inherit: 1, freq: 1, precise_ip: 3, sample_id_all: 1 # # perf report --stdio <SNIP> # Total Lost Samples: 14 # Samples: 216 of event 'cpu/mem-loads,ldlat=30/P' # Event count (approx.): 15207 # Overhead Symbol Shared Object # ........ ..................................... ............................ 10.32% [k] update_blocked_averages [kernel.vmlinux] 3.43% [.] 0x00000000001a2122 qemu-system-x86_64 (deleted) 2.52% [k] enqueue_entity [kernel.vmlinux] 1.88% [.] g_main_context_query libglib-2.0.so.0.4800.2 1.86% [k] __schedule [kernel.vmlinux] <SNIP> # Samples: 196 of event 'cpu/mem-stores/P' # Event count (approx.): 14771346 # Overhead Symbol Shared Object # ........ ................................... ............................ 13.91% [k] intel_idle [kernel.vmlinux] 3.02% [.] 0x00000000022f06ea chrome 2.94% [.] 0x00000000001a1b4c qemu-system-x86_64 (deleted) 2.94% [.] 0x000000000019d8e4 qemu-system-x86_64 (deleted) 2.38% [.] 0x00000000001a1c52 qemu-system-x86_64 (deleted) <SNIP> Signed-off-by: -
