| |
Arm SPEv1.2 adds another 64-bits of event filtering control. As the existing perf_event_attr::configN fields are all used up for SPE PMU, an additional field is needed. Add a new 'config3' field.
Tested-by: James Clark <james.clark@arm.com> Signed-off-by: Rob Herring <robh@kernel.org> --- There's still an unresolved discussion about validating 'config3' with the options laid out here[1].
v4: - Rebase on v6.2-rc1 v3: - No change v2: - Drop tools/ side update
