Andrii Nakryiko says: ==================== This patchset adds a high-level API for setting up and polling perf buffers associated with BPF_MAP_TYPE_PERF_EVENT_ARRAY map. Details of APIs are described in corresponding commit. Patch #1 adds a set of APIs to set up and work with perf buffer. Patch #2 enhances libbpf to support auto-setting PERF_EVENT_ARRAY map size. Patch #3 adds test. Patch #4 converts bpftool map event_pipe to new API. Patch #5 updates README to mention perf_buffer_ prefix. v6->v7: - __x64_ syscall prefix (Yonghong); v5->v6: - fix C99 for loop variable initialization usage (Yonghong); v4->v5: - initialize perf_buffer_raw_opts in bpftool map event_pipe (Jakub); - add perf_buffer_ to README; v3->v4: - fixed bpftool event_pipe cmd error handling (Jakub); v2->v3: - added perf_buffer__new_raw for more low-level control; - converted bpftool map event_pipe to new API (Daniel); - fixed bug with error handling in create_maps (Song); v1->v2: - add auto-sizing of PERF_EVENT_ARRAY maps; ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
