I cannot find anything in the docs which suggest this solution is correct.
Different blocks in the DPU pipeline have their own CRC (MISR) registers
like LM, intf etc.
We dont need to change INPUT_SEL to tell DPU from which pipeline to take
the CRC from as each of them have their own registers.
INPUT_SEL is controlling whether the CRC needs to be calculated over the
entire display timings or only the active pixels. I am unable to tell at
the moment why this is making a difference in this use-case.
Since I am unable to find any documentation proving this solution is
correct so far, unfortunately I would hold this back till then.
We will investigate this issue and report our findings on this thread on
how to proceed.
Alright, we debugged and also found some more answers.
The correct solution is indeed to set INPUT_SEL = 1 but let me explain
why and what should be the correct way.
INPUT_SEL was indeed telling whether to compute CRC over active pixels
or active pixels + timings like I wrote before but this behavior changed
since some chipsets.
Now, INPUT_SEL = 0 means compute CRC *only* over timings and not the
active area (and not display + timings like before) and like mentioned
before this has nothing to do with what is the input to the CRC. Not
covering the active area will not change the CRC at all as Rob reported
but its not specific to CTM.
Which means we should have been setting INPUT_SEL=1 whenever we use INTF
CRC irrespective of whether CTM is used or not.
What this also means is INTF CRC was not working correctly at all so far
irrespecive of CTM or not because it was always computing CRC only on
the timings (non-active area).
This was not caught so far because it looks like IGT's
kms_pipe_crc_basic test which was used to validate this only compares
CRC between two frames of the same content to match if they were equal
and not changing contents and comparing like kms_plane does. It will
pass as CRC would not have changed.
Now coming to the fix, the reset value of this register INTF_MISR_CTRL
already sets the INPUT_SEL bit (or unsets it) correctly based on
whichever DPU version is used so we should just change the
dpu_hw_setup_misr() to a read on the register followed by ORing the
required bits without touching INPUT_SEL and write.
That will address this issue and also cover version control since the
expected value of this bit has changed across DPU revisions.
Ok, thanks for following up on this. Mind posting a patch to
supersede this one?
BR,

Yup, we will.
Thanks

I'm not sure about the dpu_encoder and dpu_hw_intf interfaces. But
dpu_hw_setup_misr definitely needs the `u8 input_sel` parameter
instead of `bool has_ctm`.
That seems a bit premature without knowing what the other values are.

taking directly register bitfield enum's..)

dpu_hw_intf and especially dpu_hw_util are not real abstractions. I
always viewed them as useful low-level helpers.
I think that has_ctm is valid at the dpu_encoder level, which selects
which input to use. on the lower levels has_ctm

That seems a bit premature without knowing what the other values are.
(And I also question a bit the whole abstraction layer thing if it is
taking directly register bitfield enum's..)

I'm not sure about the dpu_encoder and dpu_hw_intf interfaces. But
dpu_hw_setup_misr definitely needs the `u8 input_sel` parameter
instead of `bool has_ctm`.
Most likely, I'd use u8 for dpu_hw_intf operation too.
Could you please adjust?

[PATCH] drm/msm/dpu: Fix encoder CRC to account for CTM enablement
From: Rob Clark
Seems like we need to pick INPUT_SEL=1 when CTM is enabled. But not
otherwise.
