Subject: [PATCH 0/2] firmware: arm_scmi/imx: Support dump syslog
Date: Wed, 10 Sep 2025 22:28:16 +0800 [thread overview]
Message-ID: <20250910-sm-syslog-v1-0-5b36f8f21da6@nxp.com> (raw)
This is the patch 5 and 6 from patchset [1] with switching to using raw
dump, per check with Sudeep and NXP i.MX SM firmware owner
System Manager firmware provides API to dump system log information.
So add the interface for Linux to retrieve the information.
In patch 1, I drop the two structures compared to patch 5 in [1]:
struct scmi_imx_misc_sys_sleep_rec
struct scmi_imx_misc_syslog
No other changes in this patch.
In patch 2, I switched to use debugfs to do raw dump the syslog, compared
with patch 6 in [1].
