Good catch.  I checked the ARMv8 ARM and the function payloadlen(),
can confirm the fixing is correct.

[PATCH] perf: arm-spe: Fix check error when synthesizing events

2020-07-24 Thread Wei Li
In arm_spe_read_record(), when we are processing an events packet,
'decoder->packet.index' is the length of payload, which has been
transformed in payloadlen(). So correct the check of 'idx'.
