Re: [PATCH v2 5/5] arm64/perf: Extend event mask for ARMv8.1

2016-01-29 Thread David Daney

Jan,

There was already a "[PATCH v2 5/5]" that differs from this one.

Perhaps you should resend the entire patch set and mark it v3.

Thanks,
David Daney

[PATCH v2 5/5] arm64/perf: Extend event mask for ARMv8.1

ARMv8.1 increases the PMU event number space. Detect the
presence of this PMUv3 type and extend the event mask.

The event mask is moved to struct arm_pmu so different event masks
can exist, depending on the PMU type.

[PATCH v2 5/5] arm64/perf: Extend event mask for ARMv8.1

2016-01-28 Thread Jan Glauber
ARMv8.1 increases the PMU event number space. Detect the
presence of this PMUv3 type and extend the event mask.

The event mask is moved to struct arm_pmu so different event masks
can exist, depending on the PMU type.
