2019-02-06perf thread-stack: Represent jmps to the start of a different symbolAdrian Hunter4-4/+33
The compiler might optimize a call/ret combination by making it a jmp. However the thread-stack does not presently cater for that, so that such control flow is not visible in the call graph. Make it visible by recording on the stack a branch to the start of a different symbol. Note, that means when a ret pops the stack, all jmps must be popped off first. Example: $ cat jmp-to-fn.c __attribute__((noinline)) int bar(void) { return -1; } __attribute__((noinline)) int foo(void) { return bar() + 1; } int main() { return foo(); } $ gcc -ggdb3 -Wall -Wextra -O2 -o jmp-to-fn jmp-to-fn.c $ objdump -d jmp-to-fn <SNIP> 0000000000001040 <main>: 1040: 31 c0 xor %eax,%eax 1042: e9 09 01 00 00 jmpq 1150 <foo> <SNIP> 0000000000001140 <bar>: 1140: b8 ff ff ff ff mov $0xffffffff,%eax 1145: c3 retq <SNIP> 0000000000001150 <foo>: 1150: 31 c0 xor %eax,%eax 1152: e8 e9 ff ff ff callq 1140 <bar> 1157: 83 c0 01 add $0x1,%eax 115a: c3 retq <SNIP> $ perf record -o jmp-to-fn.perf.data -e intel_pt/cyc/u ./jmp-to-fn [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0,017 MB jmp-to-fn.perf.data ] $ perf script -i jmp-to-fn.perf.data --itrace=be -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py jmp-to-fn.db branches calls 2019-01-08 13:24:58.783069 Creating database... 2019-01-08 13:24:58.794650 Writing records... 2019-01-08 13:24:59.008050 Adding indexes 2019-01-08 13:24:59.015802 Done $ ~/libexec/perf-core/scripts/python/exported-sql-viewer.py jmp-to-fn.db Before: main -> bar After: main -> foo -> bar Committer testing: Install the python2-pyside package, then select these menu options on the GUI: "Reports" "Context sensitive callgraphs" Then go on expanding the symbols, to get, full picture when doing this on a fedora:29 with gcc version 8.2.1 20181215 (Red Hat 8.2.1-6) (GCC): jmp-to-fn PID:TID _start (ld-2.28.so) __libc_start_main main foo bar To verify that indeed, this fixes the problem.

2019-02-06perf tools: Fix split_kallsyms_for_kcore() for trampoline symbolsAdrian Hunter1-0/+2
Kallsyms symbols do not have a size, so the size becomes the distance to the next symbol. Consequently the recently added trampoline symbols end up with large sizes because the trampolines are some distance from one another and the main kernel map. However, symbols that end outside their map can disrupt the symbol tree because, after mapping, it can appear incorrectly that they overlap other symbols. Add logic to truncate symbol size to the end of the corresponding map.

2019-02-06perf cs-etm: Set sample flags for exception return packetLeo Yan1-0/+44
When return from exception, we need to distinguish if it's system call return or for other type exceptions for setting sample flags. Due to the exception return packet doesn't contain exception number, so we cannot decide sample flags based on exception number. On the other hand, the exception return packet is followed by an instruction range packet; this range packet deliveries the start address after exception handling, we can check if it is a SVC instruction just before the start address. If there has one SVC instruction is found ahead the return address, this means it's an exception return for system call; otherwise it is an normal return for other exceptions. This patch is to set sample flags for exception return packet, firstly it simply set sample flags as PERF_IP_FLAG_INTERRUPT for all exception returns since at this point it doesn't know what's exactly the exception type. We will defer to decide if it's an exception return for system call when the next instruction range packet comes, it checks if there has one SVC instruction prior to the start address and if so we will change sample flags to PERF_IP_FLAG_SYSCALLRET for system call return.

2019-02-06perf cs-etm: Set sample flags for exception packetLeo Yan2-0/+259
The exception taken and returning are typical flow for instruction jump but it needs to be handled with exception packets. This patch is to set sample flags for exception packet. Since the exception packet contains the exception number, according to the exception number this patch makes decision for belonging to which exception types. The decoder have defined different exception number for ETMv3 and ETMv4 separately, hence this patch needs firstly decide the ETM version by using the metadata magic number, and this patch adds helper function cs_etm__get_magic() for easily getting magic number. Based on different ETM version, the exception packet contains the exception number, according to the exception number this patch makes decision for the exception belonging to which exception types. In this patch, it introduces helper function cs_etm__is_svc_instr(); for ETMv4 CS_ETMV4_EXC_CALL covers SVC, SMC and HVC cases in the single exception number, thus need to use cs_etm__is_svc_instr() to decide an exception taken for system call.

2019-02-06perf cs-etm: Change tuple from traceID-CPU# to traceID-metadataLeo Yan3-12/+31
If packet processing wants to know the packet is bound with which ETM version, it needs to access metadata to decide that based on metadata magic number; but we cannot simply to use CPU logic ID number as index to access metadata sequential array, especially when system have hotplugged off CPUs, the metadata array are only allocated for online CPUs but not offline CPUs, so the CPU logic number doesn't match with its index in the array. This patch is to change tuple from traceID-CPU# to traceID-metadata, thus it can use the tuple to retrieve metadata pointer according to traceID. For safe accessing metadata fields, this patch provides helper function cs_etm__get_cpu() which is used to return CPU number according to traceID; cs_etm_decoder__buffer_packet() is the first consumer for this helper function.

2019-02-06perf cs-etm: Set sample flags for trace discontinuityLeo Yan1-0/+19
In the middle of trace stream, it might be interrupted thus the trace data is not continuous, the trace stream firstly is ended for previous trace block and restarted for next block. To display related information for showing trace is restarted, this patch set sample flags for trace discontinuity: - If one discontinuity packet is coming, append flag PERF_IP_FLAG_TRACE_END to the previous packet to indicate the trace has been ended; - If one instruction packet is following discontinuity packet, this instruction packet is the first one packet to restarting trace. So set flag PERF_IP_FLAG_TRACE_START to discontinuity packet, this flag will be used to generate sample when connect with the sequential instruction packet.

2019-02-06perf cs-etm: Add last instruction information in packetLeo Yan2-0/+12
Decoder provides last instruction related information, these information can be used for trace analysis; specifically we can get to know what kind of branch instruction has been executed, mainly the information are contained in three element fields: last_i_type: this is significant type for waypoint calculation, it indicates the last instruction is one of immediate branch instruction, indirect branch instruction, instruction barrier (ISB), or data barrier (DSB/DMB). last_i_subtype: this is used for instruction sub type, it can be branch with link, ARMv8 return instruction, ARMv8 eret instruction (return from exception), or ARMv7 instruction which could imply return (e.g. MOV PC, LR; POP { ,PC}). last_instr_cond: it indicates if the last instruction was conditional. But these three fields are not saved into cs_etm_packet struct, thus cs-etm layer don't know related information and cannot generate sample flags for branch instructions. This patch add corresponding three new fields in cs_etm_packet struct and save related value into the packet structure, it is preparation for supporting sample flags.

2019-02-06perf arm cs-etm: Use event attributes to send sink information to kernelMathieu Poirier1-0/+44
The communication of sink information for a trace session doesn't work when more than on CPU is involved in the scenario due to the static nature of sysfs. As such communicate the sink information to each event by using the perf_event::attr:config2 attribute. The information sent to the kernel is an hash of the sink's name, which is unique in a system.
