[PATCH v4 0/2] Add support for periodic BKOPS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch is based on the periodic BKOPS implementation in version 8 of "support BKOPS feature for eMMC" patch.
The patch was modified to answer the following issues:
- Since mmc_start_bkops is called from two contexts now, mmc_claim_host was moved to the beginning of the function
- Also, the check of doing_bkops should be protected when determing if an HPI is needed due to the same reason.

Changes in v4:
    - Separate the polling for BKOPS completion to a different patch
    - add a flag to indicate if polling for card completion is required

Changes in v3:
    - Move the call to stop_bkops to block.c. 
      This allows us to remove the mmc_claim_host from inside the function and doesn't cause additional degradation 
      due to un-neccessary calim host operation

Changes in v2:
    - Check the number of written / discarded sectors as the trigger for checking the BKOPS need.
    - Code review fixes
