Subject: [PATCH v1 0/5] mpt3sas: Improve device readiness handling and event recovery
Date: Wed, 29 Oct 2025 23:40:44 +0530 [thread overview]
Message-ID: <20251029181058.39157-1-ranjan.kumar@broadcom.com> (raw)
This patch series enhances the mpt3sas driver’s device bring-up,
readiness detection, and event recovery mechanisms to improve
robustness in environments with slow-responding or transient
SAS/PCIe devices.
The series introduces optional control over issuing TEST UNIT READY
(TUR) commands during device unblocking, configurable retry limits,
and a mechanism to requeue firmware topology events when devices are
temporarily busy. Together, these updates reduce discovery failures
and improve recovery reliability following firmware or link events.
Ranjan Kumar (5):
mpt3sas: Added no_turs flag to device unblock logic
mpt3sas: Added issue_scsi_cmd_to_bringup_drive module parameter part-1
mpt3sas: improve device discovery and readiness handling for slow
devices part-2
mpt3sas: Add firmware event requeue support for busy devices
mpt3sas: Add configurable command retry limit for slow-to-respond
devices
