Subject: [PATCH 0/4] Add support for ARMv8.3-SPE
Date: Fri, 24 Jul 2020 17:16:03 +0800 [thread overview]
Message-ID: <20200724091607.41903-1-liwei391@huawei.com> (raw)
The ARMv8.3-SPE adds an Alignment Flag in the Events packet and filtering
on this event using PMSEVFR_EL1, together with support for the profiling
of Scalable Vector Extension operations.
Patch 1: Update the kernel driver, mainly for PMSEVFR_EL1.
Patch 2: Update the decode process of Events packet and Operation Type
packet in perf tool.
Patch 3-4: Synthesize unaligned address access events and partial/empty
predicated SVE events, also add two itrace options for filtering.
Wei Li (4):
drivers/perf: Add support for ARMv8.3-SPE
perf: arm-spe: Add support for ARMv8.3-SPE
perf auxtrace: Add new itrace options for ARMv8.3-SPE
perf: arm-spe: Synthesize new events for ARMv8.3-SPE
