Subject: [PATCH 0/2] perf: arm_spe: make the PMSCR CX bit[3] consistent across the session
Date: Thu, 13 Jan 2022 17:54:15 +0000 [thread overview]
Message-ID: <20220113175417.5523-1-german.gomez@arm.com> (raw)
The value of the CX bit of the PMSCR register is not consistent across
a perf session. There is an example in [1/2] to reproduce the issue.
This cset applies a small correction to fix the consistency issue.
- [PATCH 1/2] Makes the CX bit consistent by caching the value during
the initialization of the SPE PMU event.
- [PATCH 2/2] Allows CONTEXT packets when profiling in CPU mode.
