| 8 | SYNOPSIS | |

| 10 | [verse] | |
| 11d232ec | 11 | 'perf buildid-cache <options>' |

| 13 | DESCRIPTION | |
| 14 | ----------- | |
| 8c31a1e0 ACM |
15 | This command manages the build-id cache. It can add and remove files to/from |
| 16 | the cache. In the future it should as well purge older entries, set upper | |
| 17 | limits for the space used by the cache, etc. | |

| 19 | OPTIONS | |
| 20 | ------- | |
| 21 | -a:: | |
| 22 | --add=:: | |
| 23 | Add specified file to the cache. | |
| fc1b691d AH |
24 | -k:: |
| 25 | --kcore:: | |
| 26 | Add specified kcore file to the cache. For the current host that is | |
| 27 | /proc/kcore which requires root permissions to read. Be aware that | |
| 28 | running 'perf buildid-cache' as root may update root's build-id cache | |
| 29 | not the user's. Use the -v option to see where the file is created. | |
| 30 | Note that the copied file contains only code sections not the whole core | |
| 31 | image. Note also that files "kallsyms" and "modules" must also be in the | |
| 32 | same directory and are also copied. All 3 files are created with read | |
| 33 | permissions for root only. kcore will not be added if there is already a | |
| 34 | kcore in the cache (with the same build-id) that has the same modules at | |
| 35 | the same addresses. Use the -v option to see if a copy of kcore is | |
| 36 | actually made. | |

37 | -r:: |
| 38 | --remove=:: | |
| 8c31a1e0 | 39 | Remove specified file from the cache. |
| fbb6976c | 40 | -M:: |
| 48000a1a | 41 | --missing=:: |
| fbb6976c | 42 | List missing build ids in the cache for the specified file. |
| eeb49845 NK |
43 | -u:: |
| 44 | --update:: | |
| 45 | Update specified file of the cache. It can be used to update kallsyms | |
| 46 | kernel dso to vmlinux in order to support annotation. | |
| ef12a141 ACM |
47 | -v:: |
| 48 | --verbose:: | |
| 49 | Be more verbose. | |
