Subject: [PATCH v2 4/6] perf arm-spe: Fill address info for samples
Date: Thu, 11 Feb 2021 15:38:54 +0200	[thread overview]
Message-ID: <20210211133856.2137-4-james.clark@arm.com> (raw)
In-Reply-To: <20210211133856.2137-1-james.clark@arm.com>

From: Leo Yan <leo.yan@linaro.org>

To properly handle memory and branch samples, this patch divides into
two functions for generating samples: arm_spe__synth_mem_sample() is for
synthesizing memory and TLB samples; arm_spe__synth_branch_sample() is
to synthesize branch samples.

Arm SPE backend decoder has passed virtual and physical address through
packets, the address info is stored into the synthesize samples in the
function arm_spe__synth_mem_sample().
