2023-09-08trace-events: Fix the name of the tracing.rst fileThomas Huth
The file has been converted to .rst a while ago - make sure that the references in the trace-events files are pointing to the right location now. Signed-off-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2023-06-20meson: Replace softmmu_ss -> system_ssPhilippe Mathieu-Daudé
We use the user_ss[] array to hold the user emulation sources, and the softmmu_ss[] array to hold the system emulation ones. Hold the latter in the 'system_ss[]' array for parity with user emulation. Mechanical change doing: $ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss) Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20230613133347.82210-10-philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-03-10ebpf: fix compatibility with libbpf 1.0+Shreesh Adiga
The current implementation fails to load on a system with libbpf 1.0 and reports that legacy map definitions in 'maps' section are not supported by libbpf v1.0+. This commit updates the Makefile to add BTF (-g flag) and appropriately updates the maps in rss.bpf.c and update the skeleton file in repo.

2022-07-06ebpf: replace deprecated bpf_program__set_socket_filterHaochen Tong
bpf_program__set_<TYPE> functions have been deprecated since libbpf 0.8. Replace with the equivalent bpf_program__set_type call to avoid a deprecation warning. Signed-off-by: Haochen Tong <i@hexchain.org> Reviewed-by: Zhang Chen <chen.zhang@intel.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2021-09-17ebpf: only include in system emulatorsPaolo Bonzini
eBPF files are being included in user emulators, which is useless and also breaks compilation because ebpf/trace-events is only processed if a system emulator is included in the build.
