Subject: [PATCH v2 03/19] perf test attr: Fix legacy event encodings in group tests
Date: Tue, 13 Oct 2026 17:13:58 -0300 [thread overview]
Message-ID: <20261013201415.36428-4-acme@kernel.org> (raw)
In-Reply-To: <20261013201415.36428-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Since commit b1c5efbfd92e ("perf parse-events: Remove hard coded legacy
hardware and cache parsing"), event names are resolved with sysfs/JSON
priority over the legacy encodings, so bare cache-misses and
instructions now become the core PMU sysfs/JSON events (on x86 type 4,
configs 0x412e and 0xc0) rather than the legacy
PERF_TYPE_HARDWARE/config=3 and config=1 events the tests expect, e.g.:
expected config=3, got 0
expected disabled=0, got 1
expected mmap=0, got 1
expected comm=0, got 1
expected freq=0, got 1
expected enable_on_exec=0, got 1
expected task=0, got 1
FAILED '.../test-record-group-sampling1' - match failure
The shown diff is against the cycles group leader, as no result event
matches the expected cache-misses member anymore.
Request the legacy encodings explicitly with the legacy-hardware-config
term, introduced for this purpose, keeping the original attribute
expectations unchanged, in:
test-record-group1
test-record-group2
test-record-group3
test-record-group-sampling
test-record-group-sampling1
test-record-group-sampling2
test-stat-group1
This went unnoticed until tests/attr.sh stopped ignoring attr.py's
return value.
Fixes: b1c5efbfd92eb84d ("perf parse-events: Remove hard coded legacy hardware and cache parsing")
