Subject: [PATCH 0/3] firmware: samsung: add ACPM debugfs support
Date: Mon, 24 Feb 2025 08:01:21 +0000 [thread overview]
Message-ID: <20250224-acpm-debugfs-v1-0-2418a3ea1b17@linaro.org> (raw)
The ACPM firmware saves debug information to SRAM. Add debugfs entries
in order to expose the ACPM logs.
acpm_framework/logb_gprio_level controls the ACPM print verbosity to
the SRAM log buffer. It encodes a 64 bit value, 4 bits for each of the
16 Plugin IDs, with verbosity levels from 0xf (log error) to
0x0 (log debug).
acpm_framework/log_level has a maximum value of 2 and controls which
SRAM log buffers are printed.
Finally, acpm_framework/acpm_debug_cmd provides a way to issue
ACPM DEBUG commands to the firmware.
Add ACPM debugfs support with the above capabilities.
