mmc idle time bkops?

[Nikita Yushchenko]

Hi

Some months ago, you've been working on "idle time bkops" feature. The
latest (v6) sign of this work I could found is [1]

[1] https://lkml.org/lkml/2013/4/14/29

However this did not land in mainline, also no replies, and no sign of
any follow-up...  Complete mystery what has happened to this effort :(

What is the latest status of "idle time bkops" functionality?
Is any working implementation available?

TIA,
Nikita Yushchenko

Hi Nikita,

The patch got stuck for a while as there was a request to use the runtime
PM framework for implementing the idle time BKOPs and I didn't have the
ability to test it back then.
We plan to re-implement and test in the upcoming few months (aim to July).
Do you have a need for this feature in an earlier date or it can wait for
july?

Thanks,
Maya

Hi Maya.

Thanks for the information.

There are thoughts that missing support for "non-urgent" bkops request
could be reason of unexpected slowdowns of eMMC i/o that customer is
observing. Thus the interest on the current status.

However, no particular projects or needs yet.
