Subject: [PATCH RESEND v1 12/13] perf arm-spe: Add more sub classes for operation packet
Date: Mon, 17 Aug 2020 15:53:47 +0100	[thread overview]
Message-ID: <20200817145348.14461-13-leo.yan@linaro.org> (raw)
In-Reply-To: <20200817145348.14461-1-leo.yan@linaro.org>

For the operation type packet payload with load/store class, it misses
to support below sub classes:

  - A load/store targeting the general-purpose registers;
  - A load/store targeting unspecified registers;
  - An MRS or MSR operation at EL1 transformed to a load/store.

This patch is to add support for these sub classes.
