This is # an alternative for the use of the 'xed' and 'objdump' disassemblers # # Data-type profiling improvements: # # - Resolve types for a->b->c by backtracking the assignments until it # finds DWARF info for one of those members # # - Support for global variables, keeping a cache to speed up lookups # # - Handle the 'call' instruction, dealing with effects on registers # and handling its return when tracking register data types # # - Handle x86's segment based addressing like %gs:0x28, to support # things like per CPU variables, the stack canary, etc # # - Data-type profiling got big speedups when using capstone for # disassembling. The objdump outoput parsing method is left as a # fallback when capstone fails or isn't available. There are patches # posted for 6.11 that to use a LLVM disassembler # # - Support event group display in the TUI when annotating types with # --data-type, for instance to show memory load and store events for # the data type fields # # - Optimize the 'perf annotate' data structures, reducing memory usage # # - Add a initial 'perf test' for 'perf annotate', checking that a # target symbol appears on the output, specifying objdump via the # command line, etc # # Vendor Events: # # - Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand # Ridge, Ice Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra # Forest, Sky Lake X, Sky Lake and Snow Ridge X. Remove info metrics # erroneously in TopdownL1 # # - Add AMD's Zen 5 core and uncore events and metrics. Those come from # the "Performance Monitor Counters for AMD Family 1Ah Model 00h- 0Fh # Processors" document, with events that capture information on op # dispatch, execution and retirement, branch prediction, L1 and L2 # cache activity, TLB activity, etc # # - Mark L1D_CACHE_INVAL impacted by errata for ARM64's AmpereOne/ # AmpereOneX # # Miscellaneous: # # - Sync header copies with the kernel sources # # - Move some header copies used only for generating translation string # tables for ioctl cmds and other syscall integer arguments to a new # directory under tools/perf/beauty/, to separate from copies in # tools/include/ that are used to build the tools # # - Introduce scrape script for several syscall 'flags'/'mask' # arguments # # - Improve cpumap utilization, fixing up pairing of refcounts, using # the right iterators (perf_cpu_map__for_each_cpu), etc # # - Give more details about raw event encodings in 'perf list', show # tracepoint encoding in the detailed output # # - Refactor the DSOs handling code, reducing memory usage # # - Document the BPF event modifier and add a 'perf test' for it # # - Improve the event parser, better error messages and add further # 'perf test's for it # # - Add reference count checking to 'struct comm_str' and 'struct # mem_info' # # - Make ARM64's 'perf test' entries for the Neoverse N1 more robust # # - Tweak the ARM64's Coresight 'perf test's # # - Improve ARM64's CoreSight ETM version detection and error reporting # # - Fix handling of symbols when using kcore # # - Fix PAI (Processor Activity Instrumentation) counter names for s390 # virtual machines in 'perf report' # # - Fix -g/--call-graph option failure in 'perf sched timehist' # # - Add LIBTRACEEVENT_DIR build option to allow building with # libtraceevent installed in non-standard directories, such as when # doing cross builds # # - Various 'perf test' and 'perf bench' fixes # # - Improve 'perf probe' error message for long C++ probe names" # # * tag
