Subject: [PATCH V3 0/4] scsi: ufs: Improve UFS error handling
Date: Tue, 9 Jul 2013 14:46:14 +0530 [thread overview]
Message-ID: <1373361378-30749-1-git-send-email-sthumma@codeaurora.org> (raw)
The first patch fixes many issues with current task management handling
in UFSHCD driver. Others improve error handling in various scenarios.
These patches depends on:
[PATCH V3 1/2] scsi: ufs: Add support for sending NOP OUT UPIU
[PATCH V3 2/2] scsi: ufs: Set fDeviceInit flag to initiate device initialization
[PATCH V3 1/2] scsi: ufs: Add support for host assisted background operations
[PATCH V3 2/2] scsi: ufs: Add runtime PM support for UFS host controller driver
Changes from v2:
- [PATCH V3 1/4]: Make the task management command task tag unique
across SCSI/NOP/QUERY request tags.
- [PATCH V3 3/4]: While handling device/host reset, wait for
pending fatal handler to return if running.
Changes from v1:
- [PATCH V2 1/4]: Fix a race condition because of overloading
outstanding_tasks variable to lock the slots. A new variable
tm_slots_in_use will track which slots are in use by the driver.
- [PATCH V2 2/4]: Commit text update to clarify the hardware race
with more details.
- [PATCH V2 3/4]: Minor cleanup and rebase
- [PATCH V2 4/4]: Fix a bug - sleeping in atomic context
