Subject: [PATCH 05/11] shared/rap: Shorten the requester Control Point response timeout
Date: Thu, 1 Oct 2026 21:18:51 +0800 [thread overview]
Message-ID: <20261001131900.707485-6-cheng.jiang@oss.qualcomm.com> (raw)
In-Reply-To: <20261001131900.707485-1-cheng.jiang@oss.qualcomm.com>
RAP 4.5.4.1 gives the Requester two deadlines once it has written Get
Ranging Data, both enforced by sending Abort Operation: no On-demand
Ranging Data at all within 5 seconds of the command
(RAP/REQ/ORD/BI-01-C), and no following segment within 1 second of the
previous one (RAP/REQ/ORD/BI-02-C).
The watchdog the requester arms while waiting for a Control Point
response covered the first of those, but ran for 10 seconds, so it
would abort well after the specified deadline. Arm it for 5 seconds
instead. The per-segment deadline is handled separately by
ras_cp_arm_segment_timeout(), which uses RAS_SEGMENT_TIMEOUT.
