Subject: [cocci] [PATCH v2] scripts: coccicheck: filter *.cocci files by MODE
Date: Fri, 6 Jun 2025 14:09:36 +0800	[thread overview]
Message-ID: <20250606060936.2756980-1-quic_songchai@quicinc.com> (raw)

Enhance the coccicheck script to filter *.cocci files based on the
specified MODE (e.g., report, patch). This ensures that only compatible
semantic patch files are executed, preventing errors such as:

    "virtual rule report not supported"

This error occurs when a .cocci file does not define a 'virtual <MODE>'
rule, yet is executed in that mode.

For example:

    make coccicheck M=drivers/hwtracing/coresight/ MODE=report

In this case, running "secs_to_jiffies.cocci" would trigger the error
because it lacks support for 'report' mode. With this change, such files
are skipped automatically, improving robustness and developer
experience.
