Fedora 35 sets DEBUGINFOD_URLS by default, which might lead to unexpected stalls in perf record exit path, when we try to cache profiled binaries. # DEBUGINFOD_PROGRESS=1 ./perf record -a ^C[ perf record: Woken up 1 times to write data ] Downloading from https://debuginfod.fedoraproject.org/ 447069 Downloading from https://debuginfod.fedoraproject.org/ 1502175 Downloading \^Z Disabling DEBUGINFOD_URLS by default in perf record and adding debuginfod option and .perfconfig variable support to enable id. Default without debuginfo processing: # perf record -a Using system debuginfod setup: # perf record -a --debuginfod Using custom debuginfd url: # perf record -a --debuginfod='https://evenbetterdebuginfodserver.krava' Adding single perf_debuginfod_setup function and using it also in perf buildid-cache command.
