Good Morning,
We are seeing an issue on the rk3399 with certain Foresee emmc modules
where the module reports it supports command queuing but fails in actual
implementation.
Unfortunately there doesn't seem to be any method for the mmc core code
to detect this situation and disable command queue automatically.
There also appears to be no way to disable it at runtime.
Certain modified kernels have added a patch to enable runtime disable of
command queue entirely, but this will affect mmc core as a whole and not
just the buggy card.
Does anyone have any insight into this issue?
Thank you for your time.
Very Respectfully,
Peter Geis

Unfortunate, not me personally. I assume the issue is either be card
specific or host specific. Before looking at a disable option, we need
to know more about what goes wrong, I think.

Since v5.5, if you know how to use SDHCI debug quirks there is
SDHCI_QUIRK_BROKEN_CQE
e.g. kernel command line option sdhci.debug_quirks=0x0x2020000

TDL base cannot be zero, so the register values have been lost.
Could be a reset issue like this one but for sdhci-of-arasan.c :

Excellent, we will see if a similar implementation makes a difference

The bad news, the card still is broken, here is the kernel log:

You will need to enable dynamic debug to get more messages e.g.
kernel config: CONFIG_DYNAMIC_DEBUG=y
kernel command line:
dyndbg="file drivers/mmc/core/* +p;file drivers/mmc/host/* +p"
If it can't be made to work, you can set SDHCI_QUIRK_BROKEN_CQE in the
driver as needed.
