I have a card with BKOPS_SUPPORT set in its ext_csd and I see the
following Message during boot:
mmc0: BKOPS_EN bit is not set.
>From the eMMC spec, it looks to me that the host should set this bit
if the card reports BKOPS_SUPPORT:
7.4.60 BKOPS_EN [163]
This field allows the host to indicate to the device if it is
expected to periodically manually start background operations by
writing to the BKOPS_START field.
Am I reading this correctly? Shouldn't the mmc driver write the
register after reading the ext_csd if it wishes to perform background
operations and the card supports it?
I'm running 3.12.17 but it appears to be handled the same in the latest
kernel source.
Thanks,
David
