Subject: [PATCH 0/2] ipmi: ssif_bmc: Add support for adjustable response timeout
Date: Mon, 03 Feb 2025 21:09:12 +0800 [thread overview]
Message-ID: <20250203-ssif-response-timeout-ms-v1-0-6fe279740181@gmail.com> (raw)
The SSIF response is handled by a userspace application, which may exceed
the default 500 ms timeout when the BMC or application is under heavy load.
To provide flexibility, this patch introduces the `timeout-ms` property in
the device tree binding, allowing platforms to adjust the response timeout
as needed.
If `timeout-ms` is not specified, the default response timeout remains
500 ms, ensuring backward compatibility while giving platforms the option
to configure a longer timeout when necessary. This prevents timeouts in
cases where userspace processing may take longer.
