Subject: [PATCH v3 01/17] tools/rv: Do not skip idle in trace
Date: Tue, 15 Jul 2025 09:14:18 +0200	[thread overview]
Message-ID: <20250715071434.22508-2-gmonaco@redhat.com> (raw)
In-Reply-To: <20250715071434.22508-1-gmonaco@redhat.com>

Currently, the userspace RV tool skips trace events triggered by the RV
tool itself, this can be changed by passing the parameter -s, which sets
the variable config_my_pid to 0 (instead of the tool's PID).
The current condition for per-task monitors (config_has_id) does not
check that config_my_pid isn't 0 to skip. In case we pass -s, we show
events triggered by RV but don't show those triggered by idle (PID 0).

Fix the condition to account this scenario.

Fixes: 6d60f89691fc ("tools/rv: Add in-kernel monitor interface")
