[PATCH] drm/i915/display: Reduce log level for DP command signal timeout

[Vanshidhar Konda]

The log level for timeout after waiting for a signal on the  DP aux
channel control register is set to DRM_ERROR. But this is timeout not a
fatal error as the driver is expected to retry the command. Failure
after all retries is already captured as an error. Hence, reducing the
log for a timeout to warning instead of error.

I'll add the Signed Off by line when I re-submit the patch after a
review.

IIRC this indicates the hw is broken.

Does this indicate an issue with Intel GFX/display device, or the
display/monitor connected to the DP port?

FYI, this is for FDO #109982
(https://bugzilla.freedesktop.org/show_bug.cgi?id=109982).

From the logs, it seems like this timeout only occurs once. The next try
succeeds without issues.

There's nothing connected I believe. But in either case I believe
the aux hw should terminate with a proper timeout. I'm tempted to
blame the typec/tbt stuff here too.

From the two logs for the issue, e-DP1 is the only display connected to
the test machine when it generated this error.

>the aux hw should terminate with a proper timeout. I'm tempted to

If we think that there should be no timeout, would it make more sense to
return an error to the caller and having the caller handle the error?

Could it be possible that the addition of typec/tbt to ICL has added
additional latency to the DP register being signaled? Would it make
sense to increase the 10 ms timeout to something larger?

Imre just told me the hw timeout was increased to 4ms. So 10ms should
still be sufficient I guess. But it wouldn't hurt to at least test
longer timeouts a bit to see if the hw ever gets around to signalling
the timeout.
