2025-03-11perf test stat: Additional topdown grouping testsIan Rogers
Add a loop and helper function to avoid repetition, the loop uses arrays so switch the shell to bash. Add additional topdown group tests where a topdown event needs to be moved beyond others and the slots event isn't first in the target group. This replicates issues that occur on hybrid systems where the other events are for the cpu_atom PMU. Test with both PMU and software events. Place the slots event later in the event list.

2025-03-11perf parse-events: Corrections to topdown sortingIan Rogers
In the case of '{instructions,slots},faults,topdown-retiring' the first event that must be grouped, slots, is ignored causing the topdown-retiring event not to be adjacent to the group it needs to be inserted into. Don't ignore the group members when computing the force_grouped_index. Make the force_grouped_index be for the leader of the group it is within and always use it first rather than a group leader index so that topdown events may be sorted from one group into another. As the PMU name comparison applies to moving events in the same group ensure the name ordering is always respected. Change the group splitting logic to not group if there are no other topdown events and to fix cases where the force group leader wasn't being grouped with the other members of its group.

2025-03-11perf x86/topdown: Fix topdown leader sampling test error on hybridDapeng Mi
When running topdown leader smapling test on Intel hybrid platforms, such as LNL/ARL, we see the below error. Topdown leader sampling test Topdown leader sampling [Failed topdown events not reordered correctly] It indciates the below command fails. perf record -o "${perfdata}" -e "{instructions,slots,topdown-retiring}:S" true The root cause is that perf tool creats a perf event for each PMU type if it can create. As for this command, there would be 5 perf events created, cpu_atom/instructions/,cpu_atom/topdown_retiring/, cpu_core/slots/,cpu_core/instructions/,cpu_core/topdown-retiring/ For these 5 events, the 2 cpu_atom events are in a group and the other 3 cpu_core events are in another group. When arch_topdown_sample_read() traverses all these 5 events, events cpu_atom/instructions/ and cpu_core/slots/ don't have a same group leade, and then return false directly and lead to cpu_core/slots/ event is used to sample and this is not allowed by PMU driver. It's a overkill to return false directly if "evsel->core.leader != leader->core.leader" since there could be multiple groups in the event list. Just "continue" instead of "return false" to fix this issue.

2025-03-10perf mem: Don't leak mem event namesIan Rogers
When preparing the mem events for the argv copies are intentionally made. These copies are leaked and cause runs of perf using address sanitizer to fail. Rather than leak the memory allocate a chunk of memory for the mem event names upfront and build the strings in this - the storage is sized larger than the previous buffer size. The caller is then responsible for clearing up this memory. As part of this change, remove the mem_loads_name and mem_stores_name global buffers then change the perf_pmu__mem_events_name to write to an out argument buffer.

The EventCode field (as stored in the mhpmeventN CSRs) is actually 56 bits wide, but there is no need to keep leading zeroes in the JSON files.

2025-03-10selftests: drv-net: add xdp cases for ping.pyTaehee Yoo
ping.py has 3 cases, test_v4, test_v6 and test_tcp. But these cases are not executed on the XDP environment. So, it adds XDP environment, existing tests(test_v4, test_v6, and test_tcp) are executed too on the below XDP environment. So, it adds XDP cases. 1. xdp-generic + single-buffer 2. xdp-generic + multi-buffer 3. xdp-native + single-buffer 4. xdp-native + multi-buffer 5. xdp-offload It also makes test_{v4 | v6 | tcp} sending large size packets. this may help to check whether multi-buffer is working or not. Note that the physical interface may be down and then up when xdp is attached or detached. This takes some period to activate traffic. So sleep(10) is added if the test interface is the physical interface. netdevsim and veth type interfaces skip sleep.
